I-E67-84-4B November 11, 2001 1-1

SPECIFICWARNINGS

Use this equipment only in those classes of hazardous locations listedon the nameplate. Uses in other hazardous locations can lead to unsafeconditions that can injure personnel and damage equipment.

Allow only qualified personnel (refer to INTENDED USER in SECTION 1 -INTRODUCTION) to commission, operate, service or repair this equipment.Failure to follow the procedures described in this instruction or theinstructions provided with related equipment can result in an unsafecondition that can injure personnel and damage equipment.

Consider the material compatibility between cleaning fluids and processliquids. Incompatible fluids can react with each other causing injuryto personnel and equipment damage.

Use solvents only in well ventilated areas. Avoid prolonged orrepeated breathing of vapors or contact with skin. Solvents can causenausea, dizziness, and skin irritation. In some cases, overexposureto solvents has caused nerve and brain damage. Solvents are flammable- do not use near extreme heat or open flame.

Do not substitute components that compromise the certifications listedon the nameplate. Invalidating the certifications can lead to unsafeconditions that can injure personnel and damage equipment.

Do not disconnect equipment unless power has been switched off at thesource or the area is known to be nonhazardous. Disconnectingequipment in a hazardous location with source power on can produce anignition-capable arc that can injure personnel and damage equipment.

Remove power from the unit and allow at least one minute for the unitto discharge before performing these procedures. Failure to do soconstitutes an electrical shock hazard that can injure personnel anddamage equipment.

Disconnect the AC line cord or power lines from the operating branchcircuit coming from the source before attempting electricalconnections. Instruments powered by AC line voltage constitute apotential for personnel injury due to electric shock.

Keep the enclosure and covers in place after completing the wiringprocedures and during normal operation. Do not disconnect or connectwiring or remove or insert printed circuit boards unless power has beenremoved and the flammable atmosphere is known NOT to be present. Theseprocedures are not considered normal operation. The enclosure preventsoperator access to energized components and to those that can causeignition capable arcs. Failure to follow this warning can lead tounsafe conditions that can injure personnel and damage equipment.

All error conditions are considered catastrophic. When such an errorhas been reported, the analyzer should be replaced with a known-goodanalyzer. The non-functional analyzer should be returned to thefactory for repair. Contact the factory for a Return MaterialsAuthorization (RMA) number.

SECTION 1 - INTRODUCTION

OVERVIEW

The TB84TC Series is a line-poweredconductivity/concentration analyzer withstate-of-the-art electronics, internal andexternal diagnostic functionality, aninnovative user-interface having HotKeycapability, two user-selectable modes ofoperation, and DIN-size packaging.

Diagnostic interrogation of the internalcircuitry and external sensing devices iscontinually conducted to ensure accuracy andimmediate notification of problem situationswhen they occur. Diagnostic routines monitorslope, PV drift and instability, processvariable over/under range, and temperatureover/under range. When these diagnosticconditions occur, the analyzer can beprogrammed to induce a repetitive modulationof a given magnitude in the output current orcan be link to a relay output thus providingthe ability to alert personnel of a problemcondition.

The analyzer packaging conforms to DINstandards and has mounting options thatinclude pipe, wall, hinge, and panelinstallations. Due to the modular design ofthe electronics, changing the analyzer sensingcapability to other analytical properties suchas four-electrode conductivity can be quickand easy.

The user interface is an innovative, patentedtechnology that facilitates a smooth andproblem-free link between the user andanalyzer functionality. The programmingstructure reduces programming difficulties byproviding a toggle between Basic and Advancedfunctions.

SECTION 2 - ANALYZER FUNCTIONALITY ANDOPERATOR INTERFACE CONTROLS

INTRODUCTION

The beginning of this section contains anoverview of the TB84TC Toroidal ConductivitySeries analyzer functionality and importantinformation for configuration personnel. Thelatter part of this section discusses theoperator interface controls. It includesdescriptions of the analyzer modes andfaceplate controls.

ANALYZER OVERVIEW

The TB84TC Series analyzer provides two analogoutput signals that can be configured to spana range of solution conductivity and/ortemperature as measured by the analyzer andsensor. In addition to the two analogoutputs, three integral relay outputs can beindividually configured as a high or lowsetpoint controller, cycle-timer controller,diagnostic alarm, or cleaner controller.

The analyzer is equipped with internaldiagnostics that monitor the operation of theanalyzer’s electronics and firmware for anypotential problems. This diagnosticcapability also includes the detection ofsensor integrity such as out of range processvariables and incorrect calibration values.

USER INTERFACE

The user interface consists of a tactilekeypad having four Smart keys, one hidden key,and a custom LCD. The LCD has a three andone-half digit numeric region that displaysthe process variable, a six-digit alphanumericregion that displays secondary information andprogramming prompts, and several status-indicating and programming icons.

I-E67-84-4B November 11, 2001 2-2

Using a patented technique, each of the fourkeys is located under a given set of icons.In each of the instrument modes and modestates, one icon over any given key will beilluminated and will represent that key’sfunction. These Smart Key assignments willvary as the user enters into differentprogramming modes and states. In addition tothe Smart Key assignments, text stringslocated in the six character alphanumericfield (i.e., secondary display) are used asprogramming prompts. The end result is aninterface that provides a great deal offlexibility and functionality.

MODULAR ELECTRONIC ASSEMBLIES

The TB84TC Series analyzer consists of threeseparate PCB assemblies that concentratespecific circuit functionality onto each ofthe three boards. This modular design allowsfor the ability to change the instrument fromone of four types of instruments: pH/ORP/pION,four-electrode conductivity, two-electrodeconductivity, and toroidal conductivity. Inaddition, analyzer repairs can be quicklyaccomplished by simply replacing the non-functioning board with one that isoperational.

TEMPERATURE COMPENSATION

The process temperature can be monitored usingone of three types of RTD inputs: 3 kohmBalco, Pt100, and Pt1000. The secondarydisplay area can also be set to display thetemperature in degrees Celsius or Fahrenheitwhen the TB84TC Series analyzer is in theMeasure mode of operation.

Since temperature affects the activity anddisassociation of ions and hence theconductivity of the solution, severaltemperature compensation functions areavailable to correct for these effects.Temperature compensation options forconductivity and concentration include Manual(0.1N KCl based) and seven types of AutomaticCompensation routines. See Section 1,Introduction, for compensation types.

I-E67-84-4B November 11, 2001 2-3

ANALOG OUTPUTS

The TB84TC Series analyzer has two analogoutputs. These outputs can be either director reverse acting and can be firmware-configured to a range of zero to 20 milliampsor four to 20 milliamps. Both outputs areseparately scalable, isolated from the input,and isolated from one another.

The analog outputs provide process informationto recorders, data loggers, and controlsystems. The information transmitted canrepresent (i.e., be sourced to) theconductivity, concentration, or temperature ofthe solution and be ranged across any portionof the particular measurement range. SeeTable 1-3, Specification, for minimum andmaximum range values.

RELAY OUTPUTS

The TB84TC Series analyzer has three Form C,SPDT relay outputs jumper-selectable as eitherNormally Open (NO) or Normally Close (NC).The relays can be independently programmed toperform various functions as required by theapplication.

These functions include:

C Process control (Setpoint or Cycle Timer).C Diagnostic condition notification.C Cleaner control.

High or Low Set Point

High or low setpoint relays are configurablefor any value within the measurement range.Each setpoint relay output allows for separateprogrammability of relay function (high orlow), set point value, deadband value, anddelay.

The example shown in Figure 2-1 illustrates ahigh setpoint relay output of 10.00 mS/cm witha deadband of 0.10 mS/cm. The relay activatesat 10.00 mS/cm and deactivates when theprocess drops below 9.90 mS/cm. The secondhalf of the figure shows the same situation

with a 1.0 minute delay. The delay actsbefore the high set point relay activates.Setpoint functions are programmable as high orlow acting. Setpoint, deadband, and delayvalues are tunable parameters available in theSetpoint/Tune Mode of Operation.

Figure 2-1. High SetPoint and Time Delay Example.

High or Low Cycle Timer

High or low cycle timer relays areconfigurable for any value within themeasurement range. A cycle timer relay outputallows for separate programmability of relayfunction (high or low), setpoint value, cycletime, and on time.

The example shown in Figure 2-2 illustrates acycle timer that will be active when theprocess variable exceeds the high setpointvalue of 10.00 mS/cm. Once active, the relayoutput energizes for the configured on time.As long as the process continues to exceed thesetpoint value, the timer will reset itself atthe end of the duty cycle (i.e., cycle time).The setpoint, cycle time, and on time are alltunable parameters available in theSetpoint/Tune Mode of Operation.

FIGURE 2.2. Cycle Timer High SetPoint Example.

I-E67-84-4B November 11, 2001 2-5

Cleaner

Automatic sensor cleaning can be accomplishedusing one of the three relay outputs. At aprescribed time interval (i.e., cycle time), acleaner relay output will energize and thusenable a cleaning device. The cleaner relaywill remain energized for a configuredcleaning period (i.e., on time). Since manycleaning devices use cleaning solutions thatcan affect the process measurement, the analogand non-cleaner relay outputs can be heldduring the cleaning period. If needed, non-cleaner relay outputs can be completelydisabled (i.e., de-energized) instead of held.Thus, an operator does not need to beconcerned with the possibility of a non-cleaner relay being held in an incorrect stateduring a cleaning cycle.

In addition to a cleaning period, a recoveryperiod can be programmed to extend anyconfigured hold and/or disabling conditionbeyond the cleaning period. This featureallows cleaning fluids to dissipate and/orsensor conditions to stabilize beforereturning to the normal mode of operation.

The cycle time, on time, and recovery periodare all tunable parameters available in theSetpoint/Tune Mode of Operation.

DAMPING

Damping can be adjusted from 0 to 99.9seconds. This feature is useful in noisyprocess environments to help stabilize thedisplayed process variable and output currentfrom excess bounce. Damping can be applied tothe displayed and/or analog output values.

Damping simulates a capacitive type lag wherereaction to any signal change is slowedaccording to an entered time constant. Forexample, a step change will reachapproximately 63 percent of its final value infive seconds for five seconds of damping.

I-E67-84-4B November 11, 2001 2-6

DIAGNOSTICS

Diagnostics are provided for both the analyzerand sensor. Diagnostic detection of an ErrorCode enables preset Safe Mode states. TheseSafe Mode states are configured by the userand forces the outputs either high and/or low.

For problems that do not render the instrumentin a non-functioning state (i.e., a ProblemCode), the user has the option of linkingthese conditions to a Diagnostic Spike that issuperimposed onto Analog Output One and/or toone or more relay outputs.

If the Diagnostic Spike is enabled, AnalogOutput One will modulate for one out of everysix seconds. The magnitude of the modulationcan be set from 0 to 100% of the analyzer’smaximum output (i.e., 0 to 16 or 20 mA).

Diagnostic conditions cause the FAULT andFAULT INFO icons to be energized.Interrogation of each fault condition isavailable with a single keystroke.

Analyzer

Four critical errors in operation aremonitored and linked to the Safe Mode feature.These conditions include inoperable orincorrect input circuit, bad RAM (RandomAccess Memory), and damaged EE (ElectricallyErasable) memory.

Sensor

The analyzer continually performs diagnosticchecks on sensor integrity. Inconsistenciesin sensor performance are notified by theFAULT and FAULT INFO icons as well as theSpike Output and/or Diagnostic Relay(s) ifconfigured.

Sensor faults include shorted/open temperaturesensor, high and low PV, high and lowtemperature, and many more. See Section 13,Diagnostics, for more details.

I-E67-84-4B November 11, 2001 2-7

Spike Output

Remote notification of a problem condition canbe initiated by the TB84TC Series analyzerusing the SPIKE State in the Configure Mode.The Spike Output option allows users toprogram a 0 to 100% (i.e., 0 to 16 mA for 4 to20 mA configurations or 0 to 20 mA for 0 to 20mA configurations) pulse that will beimpressed on Analog Output One for one secondout of a six second repeating cycle should aproblem condition be detected. Should theactual output of the analyzer be below mid-scale, the pulse will add current; if abovemid-scale, it will subtract current.

SECTION 3 - INSTALLATION

INTRODUCTION

This section of the manual will aide the userin all levels of the installation process.The intention is to provide simple proceduresfor placing the TB84TC Series analyzer intoservice.

SPECIAL HANDLING

Besides the normal precautions for storage andhandling of electronic equipment, the analyzerhas special static sensitive device (SSD)handling requirements. This equipmentcontains semiconductors subject to damage bydischarge of static electricity; therefore,avoid direct contact with terminal blockconductors and electronic components on thecircuit board.

To minimize the chances of damage by staticelectricity, follow these techniques duringwiring, service, troubleshooting, and repair.

1. Remove assemblies containingsemiconductors from their protectivecontainers only:

a. When at a designated static-free workstation.

b. After firm contact with an antistaticmat and/or gripped by a grounded individual.

2. Personnel handling assemblies withsemiconductors must be neutralized to astatic-free work station by a grounding wriststrap connected to the station or to a goodground point at the field site.

3. Do not allow clothing to make contactwith semiconductors. Most clothing generatesstatic electricity.

4. Do not touch connectors, circuit traces,and components.

I-E67-84-4B November 11, 2001 3-2

5. Avoid partial connection ofsemiconductors. Semiconductors can be damagedby floating leads. Always install electronicassemblies with power removed. Do not cutleads or lift circuit paths whentroubleshooting.

6. Ground all test equipment.

7. Avoid static charges during maintenance.Make sure the circuit board is thoroughlyclean around its leads but do not rub or cleanwith an insulating cloth.

NOTE: An antistatic field service kit, part number1948385_1, is available for personnel working ondevices containing static sensitive components. Thekit contains a static dissipative work surface (mat),a ground cord assembly, wrist bands, and alligatorclip.

UNPACKING AND INSPECTION

Examine the equipment upon receipt forpossible damage in transit. File a damageclaim with the responsible transportationcompany, if necessary. Notify the nearest ABBsales office.

Carefully inspect the packing material beforediscarding it to make certain that allmounting equipment and any specialinstructions or paperwork have been removed.Careful handling and installation will ensuresatisfactory performance of the unit.

Use the original packing material andcontainer for storage. Select a storageenvironment free of corrosive vapors andextreme temperature and humidity. Storagetemperatures must not exceed -40 degrees to+70 degrees Celsius (-40 degrees to +158degrees Fahrenheit).

Remove the protective film from the analyzerlens after the analyzer has been placed in itsfinal installed location.

I-E67-84-4B November 11, 2001 3-3

LOCATION CONSIDERATIONS

When mounting the unit, leave ample clearancefor removal of the front bezel and rear cover.Signal wiring should not run in conduit oropen trays where power wiring or heavyelectrical equipment could contact orinterfere with the signal wiring.

WIRING CONNECTIONS AND CABLING

CAUTION To prevent possible signal degradation,separate metal conduit runs are recommendedfor the sensor, signal, and power wiring.

Under ideal conditions, the use of conduit andshielded wire may not be required. However,to avoid noise problems, power, signal, andoutput wiring should be enclosed in separateconduit. Just prior to entering the housing,rigid conduit should be terminated and a shortlength of flexible conduit should be installedto reduce any stress to the housing.

Note: To maintain a NEMA 4X/IP65 rating, use approvedconduit connections or cord grips that have the same typeof ratings.

Power and signal wiring must bear a suitablevoltage rating, have a maximum temperaturerating of 75ºC (167ºF), and must be inaccordance with all NEC requirements orequivalent for the installation site. Useeither a standard three-prong groundedflexible CSA certified line cord or equivalentfor power supply connections or hard wiredirectly to the AC supply. If hard wiring theAC power supply, use stranded, 14 AWG copperconductor wire.

Signal wiring should not be run in the sameconduit or open trays where power wiring forhigh amperage electrical equipment exists.Ensure the final installation of signal andpower wiring prevents physical damage and/orelectrical interfere.

Note: Use weatherproof connections for all wiring ports.Heyco RLTF ½" and LTF 9 cable grips are available throughABB. See Section 17, Support Services.

The TB84TC Series analyzer accepts wire sizes12 to 24 AWG. Signal wiring should always betwisted, shielded pairs to ensure the bestperformance. Pin-style terminals arerecommended for all connections and availableas kits from the factory. See section 17,Support Services, for more information.

I-E67-84-4B November 11, 2001 3-10

Power Wiring

WARNING Disconnect the AC line cord or power linesfrom the operating branch circuit coming fromthe source before attempting electricalconnections. Instruments powered by AC linevoltage constitute a potential for personnelinjury due to electric shock.

WARNING Keep the enclosure and covers in place aftercompleting the wiring procedures and duringnormal operation. Do not disconnect orconnect wiring or remove or insert printedcircuit boards unless power has been removedand the flammable atmosphere is known NOT tobe present. These procedures are notconsidered normal operation. The enclosureprevents operator access to energizedcomponents and to those that can causeignition capable arcs. Failure to followthis warning can lead to unsafe conditionsthat can injure personnel and damageequipment.

The TB84TC Series analyzer does not requireany adjustments to accept different line-powervoltages. Power connections are located inthe back of the instrument housing. Theterminal block label identifies all linepower, output signal, and sensor connections.

Notes:1. ABB recommends installing a power line switch forsafety purposes and for providing power-up and power-downconvenience when servicing the analyzer.

2. Do not power the system from a transformer that alsopowers large motor loads (over five horsepower) or anyother type of equipment that generates line voltagesurges, sags and excessive noise.

Using Figure 3-7 as a reference, make linepower connections as follows:

1) Strip wire insulation back approximately0.250" (seven millimeters) to ensure the barewire will make good contact with the InsulatedPin Lug terminals and will not be exposedbeyond the pin insulator.

I-E67-84-4B November 11, 2001 3-11

2) Crimp Pin Lug terminals to wire usingPanaduit CT 570 or equivalent.

3) Connect the specified line voltage toTB1-1 (Line - L1), the neutral to TB1-2(Neutral - L2), and the ground to enclosureprotective ground terminal located below TB1.

Analog Output Signal Wiring

The terminal block label identifies the analogoutput connections. Terminal polarity isshown and must be observed to ensure properoperation. The maximum load resistance forthe analog outputs is specified in Table 1-3,Specifications. The maximum load resistancemust include all devices and wiring within theanalog output current loop. See Figure 3-7for additional wiring information.

Using Figure 3-7 as a reference, make analogoutput connections as follows:


2) Crimp Pin Lug terminals to the wire usingPanaduit CT 570 or equivalent.

3) Connect the wiring to the appropriateanalog output terminals.

Relay Output Signal Wiring

The relay outputs are shipped from the factoryin the default state of Normally Open. Thatis, the relay contacts will be open when therelay is not energized. To change the normalstate of any of the three relay outputs,switches on the power supply PCB assembly mustbe moved to different positions.

GROUNDING

The customer and/or wiring contractor isresponsible to ensure the analyzer, associatedcontrol or test equipment, and all exposedconductive materials are properly grounded.Grounding procedures should be in accordancewith local regulations such as the NationalElectrical Code (NEC), Canadian ElectricalCode (CEC), or equivalent. Equipmentinstallations must not pose a hazard,including under fault conditions, to operationand service personnel.

Signal wiring should be grounded at any onepoint in the signal loop. The analyzerenclosure should be connected to earth groundusing a large area conductor having less than0.2 ohms or resistance. Internal and externalearth ground terminals are provided forconvenience and shown in Figure 3-7.

I-E67-84-4B November 11, 2001 3-15

Notes:

1. Because of the prevailing differences in soil conditionsand in acceptable grounding practices throughout the world,the scope of this product instruction is not intended to beused to describe grounding electrode systems. The customer isresponsible to ensure a grounding electrode system isacceptable to the local building and wiring codes.

2. Using the structural metal frame of a building as therequired equipment grounding conductor for the analyzer is notadvised.

OTHER EQUIPMENT INTERFACE

The TB84TC Series analyzer provides twoisolated current outputs that are proportionalto the process variable(s). Since theanalyzer output is isolated, each current loopmay have a maximum of one non-isolated devicewithin its circuit. The maximum load on theeach current loop must not exceed thespecification listed in Table 3-1,Specifications.

INSTRUMENT ROTATION

The TB84TC Series analyzer has four pairs ofthreaded mounting holes. Since these holesare located at the corners of the instrument,the TB84TC Series analyzer can be positionedin any of the four positions as demonstratedin Figure 3-8.

SECTION 4 - OPERATING PROCEDURES

INTRODUCTION

The TB84TC Series analyzer has seven mainoperating modes: Measure, Calibrate,Output/Hold, Configure, Security, secondaryDisplay, and Setpoint/Tune. Within each mode,several programming states containingfunctions specific to the related mode areavailable.

The TB84TC Series analyzer is equipped with abuilt-in user interface through which allanalyzer functions are programmed ormonitored. Two display regions in the customLCD handle the majority of instrumentfunctions. These regions include a primarydisplay area for the process variable (e.g.,Conductivity) and a secondary display area forprogramming text prompts or auxiliaryinformation.

In addition to the user-friendly interface,the TB84TC Series analyzer is equipped with agroup of icons that alerts the user to anexisting FAULT condition, diagnostic SPIKEoutput, output HOLD condition, or activatedRELAY. These icons are located at the top ofthe LCD and are only energized when thespecified condition is detected. FAULTconditions are shown in the secondary displaywhen the instrument is in the Measure Mode ofOperation and the FAULT INFO key has beenpressed.

OPERATOR INTERFACE CONTROLS REVIEW

Liquid Crystal Display (LCD)

The LCD contains nine regions that provide theuser with information on the process variable,engineering unit, mode of operation, outputhold condition, fault, relay activation,secondary variable, and key functionassignments. Figure 4-1 shows a fullyenergized LCD, Smart Keys, and mode text.

Figure 4-1. Fully Energized Display AndSupporting Information.

The top set of icons informs the user ofabnormal operating conditions such as anoutput HOLD, FAULT, diagnostic SPIKE output,or RELAY activation. These icons are onlyenergized when such a condition is detectedand are active in all modes of operation.

For the mode of operation indicators (i.e.,right arrows positioned next to the modetext), only one indicator will be lit and willindicate the current mode of operation of theanalyzer. As a user moves from one mode tothe next, the appropriate indicator willenergize. The mode of operation indicatorsare active in all modes of operation.

The process variable is displayed in the threeand one-half digit, seven segment region.This display region is supported by theengineering unit region. These regions areactive in all modes of operation; however, insome programming states, the process variableregion will be used for data entry and theengineering unit region will reflect the dataunit.

I-E67-84-4B November 11, 2001 4-3

The secondary variable is displayed in thesix-character, fourteen segment region. Thisdisplay region is used for displayingsecondary information and fault information inthe Measure Mode of Operation and programmingprompts in all other modes of operation. Dueto the limited number of characters for thisdisplay region, much of the prompting takesthe form of text abbreviations (see Appendix Cfor a list of abbreviations.) This region isactive in all modes of operation.

The Smart Key assignments are grouped intofour sets of icons, each group directlypositioned above one of the four keys. Theseicons are textual representations of thefunction for the associated key. Only oneicon will be energized per Smart Key at anygiven time.

Multi-Function Smart Keys

A five-button, tactile keypad is located onthe front panel of the analyzer. Four of thebuttons are embossed to easily show theirlocation. A fifth, hidden button located top,center of the keypad has been included toprovide access to functions that areinfrequently used.

The four embossed keys are called Smart Keyssince their functions are dependent on themode and/or state of the instrument. Sincethese four keys do not have a pre-assignedfunction, multiple functions can be assignedto a single key at different times byenergizing the appropriate icon. Using thisSmart Key method, a smaller number of keys canbe used without complicating or reducinganalyzer functionality. If a Smart Key doesnot have an icon energized above its location,this Smart Key does not have a function andwill not initiate an action when pressed.

For each operating mode and/or state, pressingthe Smart Key initiates the displayed functionof that Smart Key. For example, the functionNEXT allows a user to cycle through a seriesof programming states for a given mode ofoperation. The function SELECT enables theuser to enter into the displayed mode or stateof operation. Using this method, the TB84TCSeries analyzer guides the user through thenecessary steps used to program or monitor anygiven function. A general description of eachSmart Key function is given in Table 4-1.

MODES OF OPERATION

The Measure Mode is the normal operating modeof the TB84TC Series analyzer and is thedefault mode upon power-up. The Measure Modeis the starting point for entry into othermodes of operation. Each mode contains aunique set of analyzer functions or states.These modes and their related functions arelisted in Table 4-2.

Display Used to select the variablethat will be shown in thesecondary display region whenthe analyzer is in theMeasure Mode of Operation.

SPT/Tune Used for on-line tuning ofrelay output parameters.

HOLD ICON

The Hold icon energizes when a hold conditionis active. Outputs can be either manually orautomatically held.

Manual activation is accessible in theOutput/Hold Mode of Operation. In this mode,the Hold State permits the output to be heldat the current level and/or state or at alevel and/or state manually set by the user.

When a relay output is configured as aCleaner, an option to enable an automatic holdcondition using the levels and states capturedirectly before initiating the cleaningoperation can be selected. The hold conditiononly occurs during the cleaning relay on andrecovery times and can be separately set forthe analog and relay outputs. If desired, therelay outputs can be disabled instead of heldduring a cleaning cycle.

FAULT ICON

The Fault icon energizes when a faultcondition has been detected by the TB84TCSeries analyzer. Fault conditions include allProblem and Error Codes as outlined in Section13, Diagnostics.

I-E67-84-4B November 11, 2001 4-7

SPIKE ICON

The Spike Output function modulates AnalogOutput One from the normal levelrepresentative of the process variable to avalue configured as a set percentage of outputcurrent. When the TB84TC Series analyzer hasdetected a fault condition and the SpikeOutput function has been enabled, AnalogOutput One will begin to modulate and theSpike icon will energize. For moreinformation on Spike Output and Faultconditions, see Section 13, Diagnostics.

RELAY ICONS

The Relay icons are composed of threeindividual icons. Each icon represents one ofthe three integral relay (i.e., Relay One,Relay Two, and Relay Three.) When a relaychanges from its normal state to an energizestate, the corresponding Relay icon alsoenergizes. Since the normal state of eachrelay can be set by a switch, the relay iconwill only inform the user of a state changeand not whether the relay has closed oropened.

I-E67-84-4B November 11, 2001 5-1

SECTION 5 - MEASURE MODE

INTRODUCTION

The Measure Mode is the normal operating modeof the analyzer and is the active mode uponanalyzer power-up. In this mode, the processvariable, output hold state, fault conditionstate, spike output state, relay outputstates, and secondary display information aredisplayed. From the Measure Mode, other modesof operation and fault information can beaccessed.

BOREDOM SWITCH

If an operating mode or state other than theMeasure Mode is active, the TB84TC Seriesanalyzer automatically returns to the MeasureMode of Operation after 20 minutes ofunattended use. This feature ensures theanalyzer will always be returned to its normalmode of operation.

PRIMARY DISPLAY

The primary display shows the processvariable. The value of this variable isdependent on the configured analyzer, type oftemperature compensation, temperature value,solution conductivity, and damping value. Theengineering units for the process variable aredependent only on the configured analyzer.Table 5-1 lists the analyzer types andcorresponding engineering units.

I-E67-84-4B November 11, 2001 5-2

SECONDARY DISPLAY

The secondary display has the ability to showa large variety of information. Since thedisplay area only has six characters, only oneitem can be shown at any given time.Typically, this region will be used fordisplaying the process temperature in degreesCelsius; however, it can be changed to displaythe process temperature in degrees Fahrenheit,output current in milliamperes (i.e., mA) foreach analog output (shown separately), sensortype, conductivity value and solute name for aconcentration analyzer, and firmware revision.See Section 10, Secondary Display, for moreinformation.

FAULT INFORMATION Smart Key

Fault information can only be accessed fromthe Measure Mode of Operation and isinterrogated using the FAULT Info Smart Key.A fault condition causes the FAULT icon toblink and the FAULT Info Smart Key to appear.These indicators will be energized as long asthe fault condition is present.

When pressing the FAULT Info Smart Key, thefirst fault condition will be shown in thesecondary display. A short text stringfollowed by the fault code will besequentially shown. Depressing the FAULT InfoSmart Key progressively moves from one faultto the next until all faults have been shown.Once all faults have been interrogated, theFAULT icon will no longer blink but remainsenergized until all fault conditions have beenremoved. If a new fault condition isdetected, the FAULT icon will begin to blinkto inform the user of the newly detectedcondition. For more information on faultconditions and codes, see Section 13,Diagnostics.

SPT Smart Key

The SPT or Setpoint Smart Key provides ashort-cut directly to the SPT/TUNE Mode ofOperation. This short-cut provides quickaccess to tunable relay parameters.

I-E67-84-4B November 11, 2001 5-3

MENU Smart Key

The MENU Smart Key provides access to allother modes of operation. By pressing theMENU Smart Key, the analyzer moves from onemode of operation to the next. Visualfeedback is provided in two manners: the modeindication arrow moves to the next mode ofoperation(e.g., Calibrate) and the secondarydisplay shows the text string representativeof that mode (e.g., CALIBR). Access into thedisplayed mode of operation is allowed usingthe SELECT Smart Key. An escape function tothe Measure Mode of Operation is providedusing the Exit to MEASURE Smart Key.

As seen by the detailed screen flow diagramshown in Figure 5-1, pressing the MENU SmartKey when in the Measure Mode moves the user tothe Calibrate Mode. Once in the CalibrateMode, pressing the Exit to MEASURE Smart Keyreturns the analyzer back to the Measure Mode,pressing the SELECT Smart Key moves theanalyzer into the Calibrate States ofOperation, and pressing the MENU Smart Keymoves the analyzer to the Output/Hold Mode ofOperation. Use Figure 5-1 to identify theSmart Key assignments and the resultingaction.

Each mode of operation contains many statesused to set or tune analyzer functions. Inthe following sections of this productinstruction manual, all modes of operationwill be discussed. Screen flow diagramsshowing the programming text prompts, SmartKey assignments, and the resulting action foreach Smart Key are also included. Refer toAppendix C for programming text stringdefinitions and a programming function treeshowing the relationship of all modes andstates of operation.

SECTION 6 - CALIBRATE MODE

INTRODUCTION

The Calibrate Mode of Operation provides theability to calibrate the sensor input,temperature input, and analyzer outputs.These functions (i.e., Calibrate States ofOperation) include process variable,temperature, edit, reset, and outputcalibration.

CALIBRATE STATES OF OPERATION

The Calibrate Mode consists of six states ofoperation. Table 6-1 describes the functionof each state of operation.

Process Sensor Calibrate State

The Conductivity/Concentration Calibrate Statecontains two calibration procedures:

1) ZERO.PT (Zero-Point Calibration) and,2) SPAN.PT (Span-Point Calibration).

Figure 6-2. Screen Flow Diagram ForConductivity/Concentration Calibrate State ofOperation.

I-E67-84-4B November 11, 2001 6-4

As with the other modes and states ofoperation, the two calibration procedures canbe toggled using the NEXT Smart Key, selectedusing the SELECT Smart Key, and escaped usingthe Exit To MEASURE Smart Key.

Use Figure 6-2 to identify the Smart Keyassignments and the resulting action.

Zero-Point Calibrate State

The Zero-Point Calibrate State conducts anoffset adjustment on the sensor input. Thiscalibration procedure is typically termed anAir Calibration since the calibration isconducted with the sensor out of the processliquid or calibration standard. Variations intoroidal sensors require a Zero-PointCalibration on all new sensors. Also,periodically conduct this calibration as thesensor ages to ensure accurate performancecharacteristics.

Conduct a Zero-Point Calibration using thefollowing procedure:

1) Remove the sensor from the process pipingand thoroughly dry sensor if necessary.

2) Select the ZERO.PT in the Process SensorCalibrate State of Operation using theSELECT Key.

3) Accept the ZERO.VL by pressing the ENTERKey.

4) Confirm the displayed reading is stable(i.e., STABL?) using either the YES or NOKey. Pressing the YES Key confirms astable reading. Pressing the NO Keyreturns the TB84TC Series analyzer to theProcess Sensor Calibration State (i.e.,CON.CAL). For an unstable condition,conduct one or more of the followingsteps:

I-E67-84-4B November 11, 2001 6-5

a) Check to see if the TB84TC Seriesanalyzer detected a Faultcondition by looking for theFault icon on the LCD.Interrogate the fault by escapingto the Measure Mode using theExit to MEASURE Key and the FAULTInfo Key in that order.

b) See Section 14, Troubleshooting.

4) After a successful calibration, the Slopevalue is displayed. Press the NEXT Keyto the Offset value, or press the Exit toMEASURE Key to escape to the MeasureMode.

Poor calibration values can generate one ofthree types of warnings: BAD.CAL (i.e., BadCalibration value), UNSTBL (i.e., UnstableCalibration value), or DRIFT (i.e., DriftingCalibration value). If a BAD.CAL condition isencountered, the calibration value will not beaccepted and the analyzer will return to theCON.CAL State. If a UNSTBL or DRIFT conditionis encountered, the Slope and Offset valueswill be shown followed by a query to ACCEPTthe calibration. Though a poor calibrationvalue was encountered by the transmitter, itcan be overridden by pressing the YES Key toaccept the calibration value. The NO Keyrejects the calibration value. In both cases,the user is returned to the CON.CAL State.For more information on calibration problems,see Section 13, Diagnostics. For informationon sensor and/or transmitter troubleshooting,refer to Section 14, Troubleshooting.

Note: If an output Hold condition is present,the TB84TC analyzer inquires if this conditionshould be released.

Span-Point Calibrate State

The Span-Point Calibrate State adjusts theslope value to characterize the sensorresponse at conductivity values typical of thefinal installed location. This calibrationprocedure can be completed using two differentmethods: Grab Sample or Standard Solution.

Since toroidal conductivity sensors measure

I-E67-84-4B November 11, 2001 6-6

conductivity using inductive coupling, thesesensors are sensitive to the materials andproximity of the process piping. Thus, themost accurate calibration method uses a grabsample of the process solution while thesensor is installed in its final location.The conductivity of the grab sample ismeasured using an external validation devicewith the same type of temperaturecompensation. By subtracting the analyzerconductivity value, taken when the grab samplewas drawn, from the conductivity of the grabsample and adding this difference to thedisplayed value on the analyzer whenconducting the calibration provides an easy,accurate method of characterizing the sensorunder actual process conditions.

When the grab sample method is not practical,a Span-Point Calibration can be completedusing a known conductivity standard solutionand a sample container having the sameapproximate shape, size, and material of thesensor receptacle/piping configuration. Forthe known standard method, position the sensorin a container filled with the conductivitystandard in the same manner as it would be inthe final installed location. The calibrationvalue would be equal to the temperaturecompensated conductivity value of the standardor the actual conductivity of the standardwhen the TB84TC Series analyzer is in ManualTemperature Compensation set to 25ºC.

Conduct a Span-Point Calibration using thefollowing procedure.

1) Select the SPAN.PT in the Process SensorCalibrate State of Operation using theSELECT Key.

2) Remove the sensor from the process pipingif required.

3) Determine the conductivity of the processliquid or known solution depending on thetype of calibration methodology beingused.

I-E67-84-4B November 11, 2001 6-7

4) Enter the SPAN.VL (i.e., Span Value)using Key to increment the blinkingdigit and the Key to move to the nextdigit. Press the ENTER Key to enter thenew value.

5) Confirm the displayed reading is STABL?(i.e., stable) using either the YES or NOKey. Pressing the YES Key confirms astable reading exists. Pressing the NOKey returns the TB84TC Series analyzer tothe Process Sensor Calibration State(i.e., CON.CAL). For an unstablecondition, conduct one or more of thefollowing steps:

a) Check to see if the TB84TC Seriesanalyzer detected a Faultcondition by looking for theFault icon on the LCD.Interrogate the fault by escapingto the Measure Mode using theExit to MEASURE Key and the FAULTInfo Key in that order.

b) See Section 14, Troubleshooting.

Poor calibration values can generate one ofthree types of warnings: BAD.CAL (i.e., BadCalibration value), UNSTBL (i.e., UnstableCalibration value), or DRIFT (i.e., DriftingCalibration value). If a BAD.CAL condition isencountered, the calibration value will not beaccepted and the analyzer will return to theCON.CAL State. If an UNSTBL or DRIFTcondition is encountered, the Slope and Offsetvalues will be shown followed by a query toACCEPT the calibration. Though a poorcalibration value was encountered by theanalyzer, it can be overridden by pressing theYES Key to accept the calibration value. TheNO Key rejects the calibration value. In bothcases, the user is returned to the CON.CALState. For more information on calibrationproblems, see Section 13, Diagnostics. Forinformation on sensor and/or transmittertroubleshooting, refer to Section 14,Troubleshooting.

I-E67-84-4B November 11, 2001 6-8

Note: If using a known standard method, the measurementprinciple used by a toroidal conductivity sensor isinherently sensitive to surfaces surrounding thesensing area of the sensor. To combat this effect,clearance around the sensing area should mimic theprocess sensor fitting/piping to obtain repeatableresults.

Note: If an Output Held condition is present, theTB84TC Series analyzer inquires if this conditionshould be released.

Temperature Calibrate State

The Temperature Calibrate State is a smartcalibration routine that allows for bothsingle- and dual-point calibration. Bycalibrating the temperature at two pointswhich are at least 20 C apart, the TB84TCo

Series analyzer automatically adjusts theoffset and/or slope. Since this routine onlyuses the most recent calibration data,calibrations can be conducted throughout thesensor’s life to ensure accurate measurementof the temperature sensing device. If anincorrect calibration has been entered, theReset Calibrate State can restore thecalibration to factory settings. See ResetCalibrate State in this section.

Note: The Reset Calibrate State will reset allcalibration values including the processvariable and temperature; therefore, processvariable and temperature calibrations arerequired after performing the Reset Calibrationprocedure.

Conduct a Temperature Calibration using Figure6-3 and the following procedure:

1) Before installing the sensor into itsfinal installed location, allow thesensor to reach ambient temperature.

2) Select the Temperature Calibrate State ofOperation using the SELECT Key.

3) Set the engineering unit by pressing the Key to toggle the unit between C (i.e.,o

degrees Celsius) or F (i.e., degreeso

Fahrenheit), and press the ENTER Key touse the displayed engineering unit.

5) Edit the temperature TMP.OFF value usingthe Key to increment the blinkingdigit and the Key to move to the nextdigit. Press the ENTER Key to enter thenew value or to proceed to the EditCalibrate State. Press the Exit ToMEASURE Key to escape to the MeasureMode. Valid offset values are +/- 40 C.o

Reset Calibrate State

The Reset Calibrate State sets all calibrationdata (i.e., sensor and temperature) to factoryvalues. This state purges calibration historyand should be initiated before calibrating anew sensor.

When interrogating the calibration valuesafter a reset has been performed, the slopeand offset values for both the processvariable and temperature will be set to 1.000and 0.000, respectively.

Conduct a Reset Calibrate using the followingprocedure.

1) Select the Reset Calibrate State ofOperation using the SELECT Key.

I-E67-84-4B November 11, 2001 6-12

2) Confirm or refuse the RESET? operationusing either the YES or NO Key,respectively.

Note: The Reset Calibration State will reset allcalibration values including the processvariable and temperature; therefore, processvariable and temperature calibrations arerequired after performing the Reset Calibrationprocedure.

Analog Output One & Two Calibrate State

The Analog Output One and Two Calibrate Statetrim their respective output signals tomaintain precise transmission of the processvariable to the final monitoring system.Though the TB84TC Series analyzer outputcurrent is factory calibrated, the output canbe trimmed to compensate for otherinput/output devices.

Conduct an Output Calibration using thefollowing procedure.

1) Select the Output Calibrate State ofOperation using the SELECT Key.

2) Use the or Keys to increase ordecrease the 1 or 4 milliampere outputsignal. Press the ENTER Key to enter thenew value or to proceed to the 20milliampere output level.

Note: If the YES key was used to commission ahold condition on any output, initiating theescape function will not affect the commissionedHold condition. To release this Hold condition,the Hold State must be re-entered and the Holdcondition released either by using the YES Keywhen requested to release all hold conditions(i.e., REL.HLD) or by removing the holdcondition using the NO Key when individuallysetting each output.

If a hold condition(s) already exists and theuser selects the Hold State of Operation, theTB84TC Series analyzer will request whetherall hold conditions should be released (i.e.,REL.HLD). Press the YES Key if all holdconditions should be released and the NO Keyto edit the existing hold conditions.

Analog Output One Rerange State

The Analog Output One Rerange Output/HoldState provides the ability to change theoutput range of Analog Output One. One orboth end point values can be changed to anyvalue or range of values that are within thespecifications listed in Table 1-3.

If a non-linear output is configured,reranging the end point values will affect thenon-linear relationship. Since the non-linearrelationship is set as a percentage inputagainst a percentage output, changing the endpoint values should accompany a review of thebreak point relationship. See Section 8,Configure Mode, for information on viewing andmodifying the non-linear break points.

I-E67-84-4B November 11, 2001 7-7

Conduct a Rerange of the output values usingthe following procedure:

1) Select the Rerange State of Operationusing the SELECT Key.

2) Edit the process variable value for thezero or four milliampere point(determined by the analyzer’sconfiguration) using the Key toincrement the blinking digit and the Key to move to the next digit and pressthe ENTER Key to enter the new value, orpress the ENTER Key to continue to the 20milliampere value. Press the Exit ToMEASURE Key to escape to the MeasureMode.

3) Press the ENTER or Exit To MEASURE Key toescape to the Measure Mode, or edit theprocess variable value for the 20milliampere point using the Key toincrement the blinking digit and the Key to move to the next digit and pressthe ENTER Key to enter the new value.

Damping State

The Damping State applies a lag function onthe input signal for Basic configuration orcan apply different lag functions to thedisplay process variable, Analog Output One,and Analog Output Two for Advancedconfigurations. The Damping function reducesthe fluctuations caused by erratic processconditions. Damping values can be set from0.0 to 99.9 seconds and represent the timerequired to reach 63.2% of a step change.

For Basic configurations, the damping value isapplied to the analyzer’s input signals. Inthis case, damping will be applied to thedisplayed process variables and analogoutputs. For Advanced configurations,different damping values can be applied toeach output element (i.e., the displayedprocess variables, Analog Output One, andAnalog Output Two.)

SECTION 8 - CONFIGURE MODE

INTRODUCTION

The Configure Mode of Operation establishesthe operating parameters of the TB84TC Seriesanalyzer. These parameters includeprogramming mode, analyzer type, temperaturesensor type, temperature compensation type,analog output ranges, relay output parameters,damping value(s), diagnostic functionality,safe mode levels, and spike magnitude (i.e.,level).

A description of each configuration item andrelated parameters will be included. Revieweach of the following sections beforeconfiguring the TB84TC Series analyzer.

PRECONFIGURATION DATA REQUIRED

Before attempting to configure the TB84TCSeries analyzer, the following requirementsmust be defined.

1. Analyzer parameters.

2. Analog Output Range values.

3. Relay Output function and parameters.

4. Security requirements.

5. Sensor Diagnostic functionality.

Use the worksheets found in Appendix D to helpestablish the proper settings for any givenapplication. Use these sheets during theconfiguration entry procedure and retain themas a historical record for future reference.

CONFIGURE VIEW/MODIFY STATE

Upon selecting the Configure Mode ofOperation, a decision point is reached toModify or View the configuration of the TB84TCSeries analyzer.

the ability to view configuration information,the View Configure State can be enteredwithout using a security code.

Figure 8-1. Screen Flow Diagram ForModify/View and Basic/Advanced ConfigureStates of Operation.

As seen in Figure 8-1, the TB84TC Seriesanalyzer queries if the user would like toModify the configuration. Pressing the YESSmart Key moves the user into the ModifyConfigure State, pressing the NO Smart Keymoves the user to the View configurationquery, and pressing the Exit To MEASURE SmartKey escapes to the Measure Mode.

I-E67-84-4B November 11, 2001 8-3

If a configuration requires modification andthe user is in the View Configure State,access to the Modify Configure State isprovided through a HotKey function. TheHotKey links the View Configure State to theModify Configured State using the ENTER SmartKey. For example, the TMP.SNS (i.e.,temperature sensor) in the View ConfigureState can be modified from PT 100 to None bypressing the ENTER Smart Key when viewing thePT 100 option. An intermediate confirmationscreen will query the user on their desire tomodify this option using the YES or NO SmartKeys. If the Modify Configure State has beensecured, the security code will be requested.Upon entering the correct code or if theModify Configure State has not been secured,the TB84TC Series analyzer will go directly toTMP.SNS Modify Configure State and allow theuser to change the type of temperature sensor.After completing the change, pressing Exit ToMEASURE Smart Key moves the user to theconfiguration SAVE? State. Pressing the YESSmart Key saves the new temperature sensoroption and returns the analyzer to the MeasureMode.

BASIC/ADVANCED PROGRAMMING MODE

The Configure Mode is split into twoprogramming modes: Basic and Advanced. Thesetwo options are specified by nomenclature andcontrol the number of configuration optionsavailable in the Modify Configure State.

The Basic Programming Mode contains a subsetof configuration options found in the Advancedmode. Separation into two programming groupsreduces confusion and the possibility ofconfiguration errors.

When Advanced programming is ordered, theprogramming toggle (i.e., Basic/Advanced) mustbe set in two locations: the User State in theUtility Mode and the Modify Configure State inthe Configure Mode. In order to select eitherthe Basic or Advanced Programming Mode in theModify Configure State, the Programming Modemust be set to Advanced in the User State.See Section 12, Utility Mode, for more

I-E67-84-4B November 11, 2001 8-4

information on setting the User Stateprogramming mode to Advanced.

When in the Configure Mode and Advancedprogramming has been set in the User State,the TB84TC Series analyzer queries if the userwould like Basic programming. Pressing theENTER Smart Key moves the user to the ModifyConfigure States, pressing the NEXT Smart Keymoves the user to the Advanced programmingquery, and pressing the Exit To MEASURE SmartKey escapes to the Measure Mode. To set theanalyzer to Advanced programming, the userpresses the ENTER Smart Key when queried toset the programming to Advanced. See Figure8-1 for the corresponding screen flows.

MODIFY CONFIGURE STATES OF OPERATION

Since the View Configure State only displaysthe configured options, the following sectionswill strictly focus on each Modify ConfigureState and the available options for thesestates.

The Modify Configure State contains all theavailable settings that establishes thefunctionality of the TB84TC Series analyzer.Upon receipt of the analyzer, the defaultconfiguration (unless otherwise specified bythe customer when ordering the TB84TC Seriesanalyzer) will be used once the analyzer hasbeen powered. See the Preface for the defaultconfiguration settings.

Before installing the analyzer, theconfiguration should be modified to reflectthe final installed application. The ModifyConfigure States define the analyzer type,temperature sensor type, temperaturecompensation type, output parameters, anddiagnostic functionality. Table 8-1 describeseach of these programming modes and theirfunction.

Conductivity Analyzer State (Basic/Advanced)

The Conductivity Analyzer State does notcontain any other states of operation. OnlyABB Toroidal Sensors are compatible with theTB84TC Series analyzer.

Configure a Conductivity Analyzer State usingthe following procedure:

1) Select the ANALZR (i.e., Analyzer) Statein the Configure Mode of Operation usingthe SELECT Key.

2a) If the Programming Mode is set to Basic,the TB84TC Series analyzer will skip theAnalyzer State and go directly to theTemperature Sensor State.

2b) If the Programming Mode is set toAdvanced, choose the COND State by usingthe NEXT Key to toggle between COND andCONCEN (i.e., Conductivity andConcentration, respectively). Once thecorrect option is displayed, press theENTER Key to accept the choice.

I-E67-84-4B November 11, 2001 8-9

Note: CONCEN State is only available when theAdvanced Programming State has been purchasedand selected. See Section 12, Utility Mode,for Programming Mode selection.

Concentration State (Advanced)

The Concentration State converts conductivityvalues to concentration units. This stateapplies temperature-compensated conductivitymeasurements to a pre-defined or user-definedfunction that converts the conductivitymeasurements to concentration values having afixed decimal point location (i.e., automaticdecimal point ranging is not supported).

The Concentration State provides the followingpre-defined configurations:

! 0 to 15% Sodium Hydroxide (NaOH)! 0 to 20% Sodium Chloride (NaCl)! 0 to 18% Hydrochloric Acid (HCl)! 0 to 20% Sulfuric Acid (H SO )2 4

These pre-defined configurations are based ondata contained in the International CriticalTables. For more information on pre-definedconcentration configurations, see Appendix B,Concentration Programming.

The user-defined configuration providescapability for selecting an Engineering Uniticon, decimal point position, custom textdescription, and six-point linear curve fit.The Engineering Unit icon options includepercent (i.e., %), parts-per-million (i.e.,ppm), parts-per-billion (i.e., ppb), and noEngineering Unit icon.

The six-point linear approximation sets theend-point and break-point values of thedesired conductivity-to-concentrationconversion. The end-point values define thefull-scale output range, and the break-pointsidentify the transition points between thefive line segments that define theconductivity-to-concentration curve.

I-E67-84-4B November 11, 2001 8-10

To define the end- and break-point values, aplot of temperature-compensated conductivityagainst solute concentration must be dividedinto five line segments that best approximatethe shape of the conductivity-to-concentrationcurve. The beginning of the first and end ofthe fifth line segment identify the end-pointvalues of the linear approximation and outputrange.

Table 8-3 and Figure 8-3 show example data anda linear approximation. As can be seen bythis example, the conductivity-to-concentration curve is a non-linear functionwhich has been divided into five linesegments. The end-points represent PointNumbers 1 and 6, while the break-pointsrepresent Point Numbers 2 through 5. Alsonote, the analyzer output is linear relativeto the solute concentration. Since the end-points (i.e., Point Numbers 1 and 6) definethe full-scale output range, rerange of theoutput values is restricted to the rangebetween Point Numbers 1 and 6. For moreinformation, see Appendix B, ConcentrationProgramming.

10) Set the final end-point values (i.e.,X6.COND/Y6.CONC) using the same techniquedescribed in steps 7 and 8.

Temperature Sensor State (Basic/Advanced)

The Temperature Sensor State configures thetemperature input for a Pt100, Pt1000, 3 kohmBalco, or none. When the NONE option isentered, the temperature and temperaturecompensation will be fixed at 25 C and MANUAL,o

respectively. To change the fixedtemperature, a temperature calibration to thedesired temperature value is required.

Set the Temperature Sensor State using thefollowing procedure.

1) Select the TMP.SNS (i.e., TemperatureSensor) State in the Configure Mode ofOperation using the SELECT Key.

2) Choose the desired temperature sensor byusing the NEXT Key to toggle betweenNONE, 3K.BLCO (i.e., 3 kohm Balco),PT100, and PT1000. Enter the option byusing the ENTER Key when the correctchoice is displayed in the secondarydisplay.

Temperature Compensation State (Basic/Advanced)

Temperature has a marked effect on theconductance of many solutions. The effect isgenerally nonlinear and dependent on the typesof ions and their concentration.

The TB84TC Series analyzer contains a numberof pre-programmed correction algorithms thatcompensate for the effect of temperature onconductivity (See Table 8-5). For the BasicProgramming Mode, the conductivity referencetemperature is fixed to 25 C. For the Advancedo

Programming Mode, the reference temperaturecan be set to values other than 25 C. Valido

reference temperature values are limited tothe Specifications found in Section 1,Introduction.

I-E67-84-4B November 11, 2001 8-14

The options for temperature compensation aregrouped into two sets: MANUAL and AUTO (i.e.,Automatic). MANUAL temperature compensationdoes not contain any additional options and islocked to a specific process temperatureindependent of the selected temperaturesensor. If a different process temperature isdesired, the new temperature can be set usinga temperature calibration and will be used totemperature compensate the process variable tothe reference temperature.

The AUTO compensation options use thetemperature values measured by the input fromthe temperature sensor. Within the AUTOState, compensation algorithms includeStandard KCl (0.1N KCl based), 0 to 15% SodiumHydroxide, 0 to 20% Sodium Chloride, 0 to 18%Hydrochloric Acid, 0 to 20% Sulfuric Acid, andUser-Defined.

The User-Defined temperature compensationoption requires uncompensated conductivitydata from the reference temperature of 25 C too

the maximum process temperature using arepresentative sample of the process solution.With this data, the ratio of uncompensatedconductivity to conductivity at the referencetemperature of 25EC is calculated. Theseratios are plotted against the temperature.If a different reference temperature isdesired, the new reference temperature can beentered after entering the ratio datareferenced at 25 C, or the referenceo

temperature can remain at 25 C if the enteredo

ratio data is referenced at the desiredreference temperature.

Table and Figure 8-4 show an example of atypical user-defined temperature compensationplot. As seen in this example, the non-linearplot is segmented into five linear sections.The points (i.e., columns 1 and 3 of Table 8-4) in each row are used to define the break-points for the user-defined temperaturecompensation option. Each set of point areentered in sequence from the lowest to thehighest (e.g., 0EC/0.70 for TMP1EC/K1/K25,25EC/1.00 for TMP2EC/K2/K25, ..., 200EC/0.88for TMP6EC/K6/K25).

Analog Output One State (Basic/Advanced)

The Analog Output One State sets the outputspan, range, and function. The output span issoftware selectable for either zero to 20milliamperes or four to 20 milliamperes and issourced to the Primary Process Variable. ForBasic configurations, the output function canonly be linear. Lower and upper range valuesare defaulted to the full scale processvariable range and can be changed to any setof values conforming to Table 3-1,Specifications. For Advanced configurations,the output function can be linear or non-linear. For a non-linear output, lower andupper range values must also be set as well asfive break point values.

Linear Output State (Basic/Advanced)

The Linear Output State establishes the lowerand upper range values. The default valuesfor the output represent the full scaleprocess variable range. See Table 1-3,Specifications, for full scale variableranges.

For a reverse acting output, reverse the zeroor four and 20 milliampere values (e.g., 199.9mS/cm for the zero or four milliampere valueand 0 mS/cm for the 20 milliampere value).

Set the Linear Output State using Figure 8-5as a reference and the following procedure:

1) Select the AO1.OUT State in the ConfigureMode of Operation using the SELECT Key.

2) Set the output span using the NEXT Key totoggle between 4-20MA and 0-20MA, andpress the ENTER Key to enter the desiredspan.

I-E67-84-4B November 11, 2001 8-20

Non-Linear Output State (Advanced)

The Non-Linear Output State sets the end pointand break point values for a non-linear outputfunction. The default values for the outputrange represent the full scale processvariable range (e.g.,0 to 199.9 mS/cm). Thedefault break points are set for a linearoutput (e.g., 20% input equals 20% output).

To define the break point values, a plot ofthe process variable against the desiredoutput (or variable that represents the outputvalue) must be segmented into six linearregions that best fit the non-linearrelationship. The points where the linearregions intersect should fall on the non-linear function and represent the break pointsthat are entered into Non-Linear Output State.

As with the Linear Output State, the outputrange must be defined and will represent the0% input/0% output and 100% input/100% outputpoints. Since the 0% and 100% points aredefined by the output range, the break pointinformation (e.g., X-1/Y-1, X-2/Y-2, etc.values) should not include the 0% input/0%output and 100% input/100% output values. Thebreak points must be entered as a percentageof input range and output span. Also as witha linear output, a reverse acting non-linearoutput can be implemented by reversing thezero or four and 20 milliampere processvariable and break point values (e.g., 199.9mS/cm for the 0 or 4 milliampere value and 0mS/cm for the 20 milliampere value).

Set the Analog Output One Non-Linear Stateusing Figure 8-5 as a reference and thefollowing procedure:


2) Set the output span using the NEXT Key totoggle between 4-20MA and 0-20MA, andpress the ENTER Key to enter the desiredspan.

Setpoint Relay Output (Basic/Advanced)

A Setpoint Relay Output can be configured toenergize when the Process Variable orTemperature exceeds or falls below a definedlevel (i.e., a High or Low Setpoint,respectively). Valid Setpoint values arelimited to the Process Variable and/orTemperature ranges defined in Table 1-3,Specifications.

To prevent relay chatter, a Setpoint Relay

I-E67-84-4B November 11, 2001 8-29

Output has an configurable Deadband. TheDeadband control keeps the relay energizeduntil the Process Variable or Temperature hasdecreased below a High Setpoint value orincreased above a Low Setpoint value by theDeadband value. Valid Deadband values are 0.0µS/cm to 200 mS/cm, 0 to 10% of the configuredConcentration range for Concentrationconfigurations, and 0 to 10 C (18 F) foro o

Temperature sources.

A Time Delay control also refines the functionof a Setpoint Relay. Entering a Time Delayvalue greater than 0.0 minutes enables awaiting period before energizing the relayonce the setpoint condition has been met.Valid Time Delay values are 0.0 to 99.9minutes.

Set the Setpoint parameters of a Relay Outputusing Figure 8-11 as a reference and thefollowing procedure:

1) Set the Setpoint activation condition(i.e., HI SPT or LO SPT) using the Keyto increment the blinking digit and the Key to move to the next digit, and

press the ENTER Key to enter the newvalue.

2) Set the Deadband (i.e., DBAND) using the Key to increment the blinking digit andthe Key to move to the next digit and,press the ENTER Key to enter the newvalue.

3) Set the Time Delay in minutes (i.e.,DLY.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

Diagnostic Relay Output (Basic/Advanced)

A Diagnostic Relay Output simply energizeswhen a diagnostic condition has be detected.These conditions include all sensor andinstrument diagnostic events described inSection 13, Diagnostics.

I-E67-84-4B November 11, 2001 8-31

Set the trigger for the Diagnostic RelayOutput using the following procedure:

1) Set the Diagnostic trigger using theENTER Key to set the Relay trigger toDIAG.

Cycle Timer Relay Output (Advanced)

A Cycle Timer can only be sourced to theProcess Variable and can energize the relayfor either a High or Low setpoint condition.

Valid Setpoint values are limited to theProcess Variable range defined in Table 1-3,Specifications. Valid Cycle Time and On Timevalues are 0.0 to 99.9 minutes.

As with a Setpoint Relay Output, the Setpointcondition functions in the same manner. TheDeadband control is replaced with the CycleTime (CYC.MIN). A Cycle Timer energizes theRelay Output for a set amount of time(ON.TIME) and de-energizes for the remainderof the cycle (CYC.MIN). This cycle repeatsuntil the Setpoint condition is no longer met.For more information on the Cycle Timer, seeSection 2, Overview.

Set the Cycle Timer parameters of a RelayOutput using Figure 8-12 as a reference andthe following procedure:

1) Set the Setpoint activation condition(i.e., LO SPT or HI SPT) using the Keyto increment the blinking digit and the Key to move to the next digit, and


2) Set the Cycle Time in minutes (i.e.,CYC.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

Cleaner Relay Output (Advanced)

Automatic sensor cleaning can be achievedusing any one of the three relay outputs. Ata prescribed time interval, a Cleaner RelayOutput will energize and allow the activationof a cleaning device. While in the energizedstate, analog and relay outputs can be held tovalues captured prior to the cleaning cycle(i.e., energized state). If a relay holdcondition is not desirable, non-cleaner relayoutputs can be disable during a cleaningcycle.

I-E67-84-4B November 11, 2001 8-33

To specify a cleaning cycle, the Cycle, On,and Recovery Times must be defined. The CycleTime defines the repeating period betweencleaning cycles, the On Time defines thelength of time the relay will be energized,and the Recovery Time defines the length oftime after the relay has been de-energizedbefore the hold and/or disable condition(s)will be removed. Valid times for Cycle Timeare 0.0 to 99.9 hours and for On and RecoveryTimes are 0.0 to 99.9 minutes.

Set the Cleaner parameters of a Relay Outputusing Figure 8-13 as a reference and thefollowing procedure:

1) Set the Cycle Time in hours (i.e.,CYC.HRS) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.


3) Set the Recovery Time in minutes (i.e.,RCV.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

4) Hold the Analog Outputs (i.e., AO.HLD)during the On and Recovery Times usingthe YES Key, or leave the Analog Outputslive during the On and Recovery Timesusing the No Key.

5) Hold the Relay Outputs (i.e., RO.HLD)during the On and Recovery Times usingthe YES Key, or continue onto the DisableRelay Outputs State using the No Key.

6) Disable the Relay Outputs (i.e., DSBL.RO)during the On and Recovery Times usingthe YES Key, or leave the Relay Outputslive during the On and Recovery Timesusing the No Key.

Safe Mode One State (Basic/Advanced)

The Safe Mode One State determines the AnalogOutput One level if an error condition occursthat renders the analyzer inoperable. Theavailable states are FAIL.LO (i.e., fail low)or FAIL.HI (i.e., fail high). For moreinformation on error conditions, see Section13, Diagnostics.

Set the Safe Mode One State using thefollowing procedure:

1) Select the SAF.MD.1 State in theConfigure Mode of Operation using theSELECT Key.

2) Set the safe mode by using the NEXT Keyto toggle between FAIL.LO and FAIL.HI,and use the ENTER Key to enter the newvalue.

Safe Mode Two State (Basic/Advanced)

The Safe Mode Two State determines the AnalogOutput Two level if an error condition occursthat renders the analyzer inoperable. Theavailable states are FAIL.LO (i.e., fail low)and FAIL.HI (i.e., fail high). For moreinformation on error conditions, see Section13, Diagnostics.

Set the Safe Mode Two State using thefollowing procedure:

I-E67-84-4B November 11, 2001 8-37

1) Select the SAF.MD.2 State in theConfigure Mode of Operation using theSELECT Key.

2) Set the safe mode by using the NEXT Keyto toggle between FAIL.LO and FAIL.HI,and use the ENTER Key to enter the newvalue.

Spike State (Advanced)

The Spike State sets the diagnostic spikelevel as a percent of output. This level willdetermine the magnitude of the spike imposedon Analog Output One.

When the Spike has been set for any levelgreater than 0% and is enabled in the SpikeOutput State, the TB84TC Series analyzer willmodulate the Analog Output One signal by theconfigured level for one second out of everysix seconds when a problem condition isdetected. Using this modulation, the analyzerinforms the operator of a detected diagnosticcondition. For more information on problemconditions, see Section 13, Diagnostics. Fora description of the diagnostic spike feature,see Section 2, Analyzer Functionality AndOperator Interface Controls.

Set the Spike State using the followingprocedure:

1) Select the SPIKE State in the ConfigureMode of Operation using the SELECT Key.

2) Set the SPK.MAG (i.e., spike magnitude)using the Key to increment theblinking digit and the Key to move tothe next digit, and press the ENTER Keyto enter the new value. The SpikeMagnitude is entered as a percentage ofthe 16 milliampere output range for afour to 20 milliampere output or 20milliampere output range for a zero to 20milliampere output (e.g., 10% willgenerate a 1.6 milliampere spike for afour to 20 milliampere output range).

SECTION 11 - SETPOINT/TUNE MODE

INTRODUCTION

The Setpoint/Tune Mode of Operation provides adirect method to tune relay output parameters.Though this mode of operation can not be usedto change the function of a relay, it doesprovide the ability to quickly change relayparameters pertinent to process control. Tochange the relay output function, see Section8, Configure Mode.

SETPOINT/TUNE STATES OF OPERATION

The Setpoint/Tune Mode consists of threestates of operation: RELAY1, RELAY2, andRELAY3. Each state provides the ability toupdate operational parameters for theconfigured relay functions. For example ifRelay Output One is configured to function asa High Process Variable Setpoint, theSetpoint, Deadband, and Time Delay will betunable parameters available in theSetpoint/Tune Relay One State of Operation.

Since the tunable parameters are dependent onthe configured relay function, the followingsections will only describe the adjustment ofthese parameters.

Setpoint Relay Output (Basic/Advanced)

A Setpoint Relay Output can be configured toenergize when the Process Variable orTemperature exceeds or falls below a definedlevel (i.e., a High or Low Setpoint). ValidSetpoint values are limited to the ProcessVariable and/or Temperature ranges defined inTable 1-3, Specifications.

I-E67-84-4B November 11, 2001 11-2

To prevent relay chatter, a Setpoint RelayOutput has an configurable Deadband. TheDeadband control keeps the relay energizeduntil the Process Variable or Temperature hasdecreased below a High Setpoint value orincreased above a Low Setpoint value by theDeadband value. Valid Deadband values are 0.0µS/cm to 200 mS/cm for conductivity, 0 to 10%of the configured Concentration range forConcentration configurations, and 0 to 10 Co

(18 F) for Temperature sources.o

A Time Delay control also refines the functionof a Setpoint Relay. Entering a Time Delayvalue greater than 0.0 minutes enables awaiting period before energizing the relayonce the setpoint condition has been met.Valid Time Delay values are 0.0 to 99.9minutes.

Set the Setpoint parameters of a Relay Outputusing Figure 11-1 as a reference and thefollowing procedure:



2) Set the Deadband (i.e., DBAND) using the Key to increment the blinking digit andthe Key to move to the next digit and,press the ENTER Key to enter the newvalue.

3) Set the Time Delay in minutes (i.e.,DLY.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

Cycle Timer Relay Output (Advanced)

A Cycle Timer can only be sourced to theProcess Variable and can energize the relayfor either a High or Low setpoint condition.

As with a Setpoint Relay Output, the Setpointcondition functions in the same manner;however, the Deadband control is replaced withthe Cycle Time. Thus, a Cycle Timer energizesthe Relay Output for a set amount of time(ON.TIME) and de-energizes it for theremainder of the cycle (CYC.MIN). This cyclerepeats until the Setpoint condition is nolonger met. For more information on the CycleTimer, see Section 2, Overview.

Valid Setpoint values are limited to theProcess Variable range defined in Table 1-3,Specifications. Valid Cycle Time and On Timevalues are 0.0 to 99.9 minutes.

I-E67-84-4B November 11, 2001 11-5

Set the Cycle Timer parameters of a RelayOutput using Figure 11-3 as a reference andthe following procedure:



2) Set the Cycle Time in minutes (i.e.,CYC.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.


Cleaner Relay Output (Advanced)

Automatic sensor cleaning can be accomplishedusing any one of the three relay outputs. Ata prescribed time interval, a Cleaner RelayOutput will energize and allow the activationof a cleaning device. While in the energizedstate, analog and relay outputs can be held tovalues captured just prior to the cleaningcycle (i.e., energized state). If a relayhold condition is not desirable, non-cleanerrelay outputs can be disable during a cleaningcycle.

To specify a cleaning cycle, the Cycle, On,and Recovery Times must be defined. The CycleTime defines the repeating period betweencleaning cycles, the On Time defines thelength of time the relay will be energized,and the Recovery Time defines the length oftime after the relay has been de-energizedbefore the hold and/or disable condition(s)will be removed. Valid times for Cycle Timeare 0.0 to 99.9 hours and for On and RecoveryTimes are 0.0 to 99.9 minutes.

I-E67-84-4B November 11, 2001 11-6

1) Set the Cycle Time in hours (i.e.,CYC.HRS) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.


3) Set the Recovery Time in minutes (i.e.,RCV.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

4) Hold the Analog Outputs (i.e., AO.HLD)during the On and Recovery Times usingthe YES Key, or leave the Analog Outputslive during the On and Recovery Timesusing the No Key.

SECTION 12 - UTILITY MODE

INTRODUCTION

The TB84TC Series analyzer contains a UtilityMode of Operation that provides access topowerful functions not used during normaloperating conditions. These functions havebeen separated into two categories: Factoryand User. Factory functions are strictlyreserved for ABB personnel.

User functions include Programming Mode, resetconfiguration to default settings, removesecurity, reset all parameters to defaultsettings, and software reboot routines.

FACTORY/USER STATE

The Factory and User States of Operation canbe accessed using the hidden fifth key locatedtop, center on the keypad. Once the hiddenkey has been pressed, the textual prompt USERwill be displayed in the secondary displayregion. Pressing the SELECT Smart Key bringsthe user into the User State, pressing theNEXT Smart Key brings the user to the Factoryselection, and pressing the Exit to MEASURESmart Key escapes back to the Measure Mode.

User State

The User State contains the primary toggle forsetting the Programming Mode, three resetfunctions, and a software reboot operationthat initiates the self-test mode. Table 12-1describes the function of each User State.

The NEXT Smart Key sequentially moves througheach of the four User States. This cyclerepeats until a state is selected or theescape function is chosen using the Exit toMEASURE Smart Key. To select a state, pressthe SELECT Smart Key when the desired UserState is shown in the secondary displayregion.

SECTION 13 - DIAGNOSTICS

INTRODUCTION

The TB84TC Series analyzer performs a numberof diagnostic checks on hardware, firmware,and sensor functions. If a nonconformingcondition is detected, the user is alerted tofaults locally by a flashing FAULT indicatingicon, and if configured, remotely bymodulating Analog Output One (i.e., SpikeOutput) and/or energizing a Relay Output(i.e., Diagnostic Relay Output).

Diagnostic faults are interrogated using theFAULT Info Smart Key. A short text string andfault code are alternately shown in thesecondary display region. If multiple faultsexist, the FAULT Info Smart Key moves the userto the next fault. Once all faults have beeninterrogated, the analyzer returns to theMeasure Mode of Operation.

The following section describes the types offault conditions and their applicability tothe TB84TC Series functionality.

FAULT CODES

Fault conditions are grouped into twocategories based on severity. Conditions thatresult in degradation of analyzer performanceare reported as Problem Codes (PC), whileconditions that render the analyzer inoperableare reported as Error Codes (EC).

Fault codes are reported in the secondarydisplay region in a first in, first out order(i.e., the first detected fault condition isthe first condition that is displayed uponinterrogation). All active fault conditionscan be viewed at any time while in the MeasureMode using the FAULT Info Smart Key. Aflashing Fault icon indicates a new faultcondition that has not been interrogated. Anon-flashing Fault icon indicates all faultconditions have been interrogated but notresolved. When all fault conditions areresolved, the Fault icon and FAULT Info SmartKey are de-energized.

I-E67-84-4B November 11, 2001 13-2

Problem Codes

Problem Codes result from fault conditionsthat impact the performance of the TB84TCSeries analyzer. In most cases, theseconditions can be resolved by the user usingstandard practices.

The occurrence of a Problem Code faultcondition triggers the Fault icon to energize,the Spike output to modulate (if configured),and a Diagnostic Relay Output to energize (ifconfigured). These diagnostic indicatorsprovide local and remote reporting capability.

Tables 13-1 and 13-2 contain all the ProblemCodes supported by the TB84TC Series analyzer.Each entry lists the Problem Code number,displayed text string, and a short descriptionof the fault. See Section 14,Troubleshooting, for resolving a faultcondition.

Error Codes

Error Codes result from fault conditions thatrender the TB84TC Series analyzer inoperable.In most cases, these conditions can not beresolved by the user using standard methods.

The occurrence of an Error Code faultcondition triggers the Fault icon to energizeand the Safe Mode outputs to enable (i.e., theAnalog Output One and Two currents are fixedhigh or low based on the configured Safe Modelevels). These diagnostic indicators providelocal and remote reporting capability.

I-E67-84-4B November 11, 2001 13-5

Calibration Diagnostic Messages

During a Conductivity or Concentrationcalibration, the TB84TC Series analyzermonitors the quality and value of the processvariable signal. Poor signals will generateone of three type of warnings: BAD.CAL (i.e.,Bad Calibration value), UNSTBL (i.e., UnstableCalibration value), or DRIFT (i.e., DriftingCalibration value). A BAD.CAL conditionoccurs when the analyzer can not lock onto asignal. This condition typically only occurswhen a PV Overrange/Underrange Error (i.e.,EC1 or EC2 Error Code, respectively) exists.A BAD.CAL condition rejects the calibrationvalue and returns the analyzer to the CON.CALState after displaying the BAD.CAL textstring. Unstable (i.e., UNSTBL) or DRIFTconditions are also undesirable occurrencesand considered problematic; however, for theseoccurrences the user has the option to acceptthe calibration after viewing the calibrationslope and offset data.

In addition to the above real time calibrationdiagnostics, the TB84TC Series analyzerperforms automatic efficiency and offsetcalculations relative to a theoreticallyperfect conductivity and/or temperature sensorduring each calibration cycle. Calibrationhistory is retained for future interrogationand modification using the Edit CalibrateState. The calibration constants that aredisplayed are Slope and Offset for the ProcessVariable and Temperature.

A Slope of less than 0.2 or greater than 5indicates a potentially bad processcalibration point or poorly performing sensor.In these cases, the text string BAD.CAL (i.e.,bad calibration) is displayed in the secondarydisplay region and the calibration data isreturned to the previously stored values. Theanalyzer returns to the beginning of thecalibration cycle after a bad calibration hasbeen reported.

I-E67-84-4B November 11, 2001 13-6

An Offset value of less than -100 mS/cm orgreater than 100 mS/cm also indicates apotentially bad process calibration or poorlyperforming sensor. Again, the problem isdisplayed using the text string LO OFF (i.e.,Low Offset) or HI OFF (i.e., High Offset). Aswith the slope variances, the calibration datais returned to prior values when a bad processcalibration is encountered.

For temperature, a bad calibration will bereported and calibration values will not beaccepted for Slope values that are less than0.2 or greater than 1.5 and Offset values thatare less than -40 C or greater than +40 C.o o

Temperature calibrations use smart softwareroutines that automatically adjust the Slope,Offset, or both values based on thecalibration value being entered andcalibration history if it exists.

Additional Diagnostic Messages

Other diagnostic messages may appear duringanalyzer programming. These messages includeBAD.VAL (i.e., bad value), DENIED and RAM.ERR. BAD.VAL indicates the attempted numeric entryof a value which is out of the allowedanalyzer range. See Table 1-3,Specifications, for analyzer range limits.

DENIED indicates incorrect entry of a securitypassword. See Section 9, Security Mode, forinformation on the Security Mode of Operation.

RAM.ERR indicates a Random Access Memoryread/write error. The analyzer willautomatically reset when this error has beenencountered. If the analyzer continues toreset, contact ABB for problem resolution.

SENSOR TROUBLESHOOTING

If the sensor is suspected of being the sourceof problems, a quick visual inspection in manycases will identify the problem. If nothingcan be seen, a few electrical tests using adigital multimeter can be performed todetermine if the sensor is at fault. Some ofthese tests can be performed with the sensoreither in or out of the process stream.

Visual Sensor Inspection

Remove the sensor from the process andvisually check the following:

Sensor bodyInspect the sensor body for cracks anddistortions. If any are found, contact ABBfor alternative sensor styles and materials.

Cable and connectors Inspect the sensor cable for cracks, cuts, orshorts. If a junction box and/or extensioncable are used, check for moisture, oil,corrosion, and/or particulates where

RTC'(((T&25)(0.0045)%1)(3000

I-E67-84-4B November 11, 2001 14-6

connections are made. All connections must bedry, oil-free, corrosion-free, andparticulate-free. Even slight amounts ofmoisture, corrosion, and particulates canshort sensor signals and affect conductivityreadings. Check to see that all wiring is dryand not shorting against any metal, conduit,or earth grounds. See Section 15,Maintenance, for sensor cleaning procedures.

O-ring sealsInspect the O-ring seals for attack by theprocess liquid. If the O-rings show evidenceof corrosion, distortion, or deterioration,contact ABB for replacement O-rings oralternate material choices.

Sensor Electronic Test

Toroidal conductivity sensors can beelectronically tested to verify the integrityof the sensor and cable. The sensor and RTDmust be disconnected from the analyzer beforeany tests can be performed. Additionally,these tests require a Digital Multimeter (DMM)that has a conductance function capable of 0to 200 nS and a resistance function capable of0 to 20 kohms.

The RTD can be tested with the sensor in theprocess as follows:

1. Check the resistance of the TemperatureCompensator by measuring the resistancebetween the yellow and blue TemperatureCompensator leads.

For a 3 kohm Balco RTD, the expectedresistance can be calculated using:

where T is in degrees Celsius. The measuredresistance should be within the expected valueby ± 15%.

For a Pt100 RTD, the expected resistance canbe calculated using:


For a Pt1000 RTD, the expected resistance canbe calculated using:


Moisture inside the sensor can be detectedwithout removing the sensor from the processusing the following procedure:

1. Check the conductance between the yellowRTD lead and each of the other sensor leads(i.e., blue, red, white, black, and heavygreen leads). The reading must be less than0.05 nS.

2. Check the conductance between the blueDrive lead and one of the Sense leads (i.e.,white or red). The reading must be less than0.05 nS.

3. Check the conductance between the blueDrive lead and the exposed metal surface onthe back of the sensor. Repeat using the redSense lead. Both readings must be less than0.05 nS.

4. Check the conductance between the heavygreen lead (i.e., Shield) and each of theother sensor leads (i.e., blue, yellow, black,green, red, and white leads). The readingmust be less than 0.05 nS.

APPENDIX A - TEMPERATURE COMPENSATION

GENERAL

The TB84TC Series analyzer has a variety ofstandard conductivity temperature compensationoptions. These include manual (0.1 N KCl),standard automatic (0.1 N KCl), temperaturecoefficient (0 to 9.99%/ C), zero to 15 percento

sodium hydroxide (NaOH), zero to 20 percentsodium chloride (NaCl), zero to 18 percenthydrochloric acid (HCl), zero to 20 percentsulfuric acid (H SO ), and user-defined.2 4

The concentration analyzer configurationoffers the same temperature compensationoptions as for the standard conductivityanalyzer configuration.

CONDUCTIVITY AND CONCENTRATION ANALYZER

For these two analyzer types, eight differenttypes of temperature compensation areavailable. Manual temperature compensation isbased on 0.1 N KCl. For Basic Programming,the reference temperature is fixed to 25degrees Celsius. Advanced Programmingprovides the ability to set the referencetemperature to any value within full scaletemperature range of -20 to 200 degreesCelsius.

Automatic temperature compensation can be setto one of several temperature compensationoptions. When automatic compensation isconfigured, the analyzer will measure theprocess temperature via the resistivetemperature device located either in theconductivity sensor or external to the sensorand will automatically adjust the rawconductivity to a conductivity referenced to avalues established by the user (25 degreesCelsius is the default setting.) As withManual compensation, the reference temperatureis limited to the range of -20 to 200 degreesCelsius.

The temperature coefficient option allows fora fixed correction that is based on apercentage change of the referenceconductivity (i.e., conductivity at thereference temperature - typically 25 C) pero

degree Celsius. The temperature compensationfactor is derived from the equation:

where:

" and TC.COEF = percentage change in thereference conductivity per degree Celsius.

K = conductivity at temperature T ( C).To

K = conductivity at the standard temperatureREFof 25 C.o

T = temperature of the solution in degreesCelsius.

Typical ranges for temperature compensationcoefficients are:

C Acids = 1.0 to 1.6%/ C.o

C Bases = 1.8 to 2.0%/ C.o

C Salts = 2.2 to 3.0%/ C.o

C Neutral Water = 2.0%/ C.o

The zero to 15 percent NaOH compensationoption characterizes an average temperaturecorrection required to cover a zero to 15percent NaOH concentration range. Since NaOHhas a relatively constant set of temperaturecoefficients over a large range ofconcentrations, this compensation can be usedfor weak as well as concentrated solutions ofNaOH.

APPENDIX B - CONCENTRATION PROGRAMMING

GENERALThe concentration analyzer configurationconsists of four solute option and a user-defined option. The specific solute optionsinclude zero to 15 percent NaOH, zero to 20percent NaCl, zero to 18 percent HCl, and zeroto 20 percent H SO . The user-defined option2 4

provides a six-point, five-segment linearapproximation of a conductivity-to-concentration curve. For this option, customunits can be used by either selecting one ofthree engineering unit icons and/or entering asix-character, alphanumeric character string.

USER PROGRAMMED CONCENTRATION TO CONDUCTIVITY CURVES

The TB84TC Series concentration analyzer canbe use with any ABB Model TB404 Toroidalconductivity sensor. The user-defined optionallows the characterization of aconcentration-to-conductivity curve which hasbeen determined separately in a laboratory orfrom published data such as the InternationalCritical Tables. This curve must be segmentedinto five straight lines and programmed intothe function generator using the format asillustrated in Figures B-1 through B-5.

Unlike other concentration analyzers, usersmay enter any conductivity and concentrationvalues in an ascending or descending method.Use the following rules when entering data fora Concentration Analyzer configuration:

1. Point 1 for both conductivity andconcentration is always the 0% (i.e., 0or 4 mA) output point.

2. Point 6 for both conductivity andconcentration is always the 100% (i.e.,20 mA) output point.

3. All conductivity must be sequentiallyascending. Concentration points can beeither sequentially ascending ordescending.

I-E67-84-4B November 11, 2001 B-2

4. If a reverse acting output is desired,swap the output range values either inthe modify configure state or theoutput/hold mode.

5. The output range (i.e., 0 or 4 and 20 mAoutput range) can not exceed Point 1 and6 concentration range; however, theoutput range can be compressed using thererange (RERNGE) function in the OUT/HOLDmode of operation.

Users may also define their own engineeringunits by selecting either the PPM, PPB, or %icon. This icon will be energized in theprimary display. If one of these icons is notapplicable, the option of not using an icon isavailable. In these cases, the six-character,alphanumeric description field can be used topermanently or temporarily display processvariable information in the secondary displayfield.

For processes with fixed solute types, theuser can select one of the four pre-definedsolute options. These options include zero to15 percent NaOH, zero to 20 percent NaCl, zeroto 18 percent HCl, and zero to 20% H SO .2 4

For reference processes, the followinginformation is provided for these fourpreprogrammed options. This information hasbeen compiled and extrapolated from theInternational Critical Table. All data andcurves are referenced at 25 C. Thiso

information has been curve-fitted to simpleequations for use in the TB84TC Seriesanalyzer and only approximates the actualconcentration curves. If improved accuracy isrequired, especially in a narrow region ofconcentration, it is suggested that the user-defined option is selected and the data bemanually entered.
