The PLUSand MINUS keys are used for option selectionand editing. Selections must be confirmed bypressing the ENTER key. This also moves thecursor to the next function.Pressing the PLUS and MINUS keys at thesame time terminates programming (return tomain menu).
Note:
• If a change is made but notconfirmed by pressing the ENTERkey, the previous setting isretained.
• See the appendix of theseoperating instructions for anoverview of the menu structure.

Hold function: “freezes” the outputs
The current output is “frozen” in the setupmode and during calibration, i.e. the lastcurrent value is constantly output. The displayshows the “HOLD” message (see chapter 5.8,page 44 for hold settings).
Note:
• During automatic operation, allcontacts will go to their normalpositions.
• All hold settings are ignored for timer andthe external hold function, i.e. hold isalways activated for these functions.
• Any alarm delay accumulated will be resetto ‘0’.
• This function can also be activatedexternally via the hold input (seeconnection diagram in Fig. 3.7; digitalinput 1).
• The manual hold (field S3) remains activeeven after a power failure.
4.6 Access codes
All instrument access codes are fixed, i.e.they cannot be modified. Three access codesare distinguished (cf. Fig. 4.3):
• Any code: Read mode access, i.e. allsettings can be viewed but not modified(access with ENTER/CAL key, see Fig. 4.3).
• Code 22: Access to calibration and offsetmenus (access with CAL key, see Fig. 4.3).
• Code 22: Access to configuration menusfor instrument configuration and usersettings (access with ENTER key, seeFig. 4.3).
• See chapter 4.3, page 15 for hardwarelocking and unlocking.
4.7 Display during measurement
The measurement display can be individuallyadapted to user requirements.
Settings accessed with PLUS key:
• Press the PLUS key to display thetemperature in °F instead of °C.
• Press the PLUS key a second time tosuppress the temperature display.
• Press the PLUS key a third time to displaythe uncompensated conductivity value.
• Press the PLUS key a fourth time to returnto the standard display.
Settings accessed with MINUS key:
• Press the MINUS key to display the firsterror message.
• Press the MINUS key repeatedly to displaythe following error messages (up to ten).If no further errors exist, the display returnsto the measuring mode.
Note:
Function group F (alarm, seechapter 5.4.1) can be used to definean alarm for each individual errorcode.

Polarisation effects in the interface betweenelectrode and measuring solution limit themeasuring range of conductive conductivity
sensors. The ACM-X transmitter has the abilityto detect polarisation effects using anintelligent signal evaluation process.
PCS alarm (Process Check System)
This function is used to examine the measuringsignal for deviations. If the measuring signalis constant for a specific period of time (severalmeasured values), an alarm is issued. Thistype of sensor behaviour may be caused bysoiling, etc.

5.5 Relay contact configuration
The relay contacts described below can beselected and configured as required (up tofour with four contacts depending on optionsinstalled).
• Limit contactor for measured conductivityvalue: R2 (1)
• Limit contactor for temperature: R2 (2)• P(ID) controller: R2 (3)• Timer for cleaning function: R2 (4)• USP 23: R2 (6) (S version, conductive only)
5.5.1 Limit contactor for measured conductivity value and temperature
The relay contacts in the ACM-X can beassigned different functions.Switch-on and switch-off points and pickupand dropout delays can be defined for thelimit contactor. Moreover, an alarm thresholdcan be set to issue an error message and tostart a cleaning function.These functions may be used for conductivityand temperature measurement.
Please refer to Fig. 5.5 for a graphicrepresentation of the contact states of anyrelay or alarm contact.
When the measured value increases (maxfunction), the relay contact is closed at time t2when the switch-on point has been exceeded(t1) and the pickup delay (t2 – t1) has expired.When the alarm threshold (t3) is reached andthe alarm delay (t4 – t3) also has expired, thealarm contact is switched.When the measured value decreases, thealarm contact is reopened when themeasured value drops below the alarmthreshold (t5), and the relay contact alsoopens (t7, after the dropout delay t7 – t6).When the pickup and dropout delays are setto 0 s, the switch-on and switch-off points areidentical to the contact switching points.Settings analogous to the max function canalso be made for a min function.
5.5.2 P(ID) controller
The transmitter supports the definition ofvarious controller functions. On the basis ofthe PID controller, P, PI, PD and PIDcontrollers can be implemented. The
best control response is obtained using thecontroller best suited to the application inquestion:

P controller: Used for simple linear controlpurposes with small system deviations. Wheremajor changes are to be controlled,overshooting may occur. A control offset is tobe expected.
PI controller: Used for processes whereovershooting is to be avoided and permanentoffsets are not allowed.
PD controller: Used for processes thatrequire quick response and where peaks areto be corrected.
PID controller: Used for processes for whichthe type of control provided by a P, PI or PDcontroller is inadequate.
Adjustments of P(ID) controller
Three parameters can be adjusted in thecase of a PID controller:
– the control gain Kp (P influence)– the integral action time Tn (I influence)– the derivative action time Tv (D influence)

If there is no previous experience for thecontrol parameter settings, values should beused which guarantee maximum control loopstability (see table).
For optimisation, the control gain Kp is reduceduntil the control variable overshoots slightly.Then Kp is increased somewhat, and the Tnsetting is reduced (shorter times) to obtain theshortest possible correction time withoutovershooting.Tv must also be adjusted in the case of fastcorrection times.

The control contact in question outputs aswitched signal. The intensity of this signal isproportional to the controller’s control output.A distinction is made according to the type ofsignal output:
• Pulse length modulationThe greater the calculated control output,the longer the contact in question remainspicked up. The period can be adjustedbetween 0.5 and 99 s. Pulse length-modulated outputs are used to controlsolenoid valves.
• Pulse frequency modulationThe greater the calculated control output,the higher the switching frequency of thecontact. The maximum switchingfrequency 1/T can be adjusted between60 and 180 min–1. The ON period tON isconstant. Pulse frequency-modulatedoutputs are used to control solenoid-operated metering pumps.

Control characteristic for direct and inverted control action
Field R236 offers two control characteristicsfor selection which have the effects shown inthe following diagram.
5.5.3 USP 23 function (conductive only)
The transmitter ACM-X can measure andmonitor the uncompensated conductivity(R2 (6)) according to USP (“United StatesPharmacopeia”) guidelines.
USP requirements on measurement
The measurement is performed as follows:
• Measurement of uncompensatedconductivity
• Temperature measurement at place ofconductivity measurement
• Rounding of temperature to the next5 °C step
• Determination of applicable monitoringvalue from a table (see below)
• Alarm signalling in the event the monitoringvalue is exceeded.
The measurement is performed withoutcompensation, and the measured value iscompared to a monitoring value (see table)for pure water.An alarm is issued when the monitoring valueis exceeded.An adjustable pre-alarm can be used to alertto undesirable operating conditions in time.

5.6 Temperature compensation
The temperature coefficient specifies thechange in conductivity per degree oftemperature change. It depends on thechemical composition of the medium andthe temperature itself.
In order to compensate for this dependence,four different compensation types can beselected in the ACM-X:
Linear compensation
The change between two temperature pointsis considered to be constant, i.e. α = const.The α value can be edited for the linearcompensation type. The reference temperatureis 25 °C.
NaCl compensation
The NaCl compensation (according toIEC 746) is based on a fixed nonlinear curvethat defines the relationship between thetemperature coefficient and the temperature.This curve is used for lower concentrations.
Ultrapure water compensation
Just like the NaCl compensation, the ultrapurewater compensation is based on a nonlinearcurve stored in the instrument.This curve is split up into NaCl solution andultrapure water components. These arecalculated separately but then used togetherto determine the overall relationship.

Temperature compensation with table(S version only; available as an option)
The user can set up a table containing up toten value pairs for a special user-definedmedium so that the temperature dependenceof the temperature coefficient for any fluid canbe handled.
If the temperature coefficient for differenttemperatures is known, the correspondingvalues can be entered in the table. If thetemperature dependence of the medium isnot known, it first needs to be determined asfollows:
– Select the temperature range in which themeasurement is to take place.
– Take a sample of the process medium.– Measure the uncompensated conductivity
at different temperatures. Heat up thesample slowly to do this. Determine theuncompensated conductivity at differenttemperatures.
– The α value which corresponds to thetemperature and the conductivity value isdetermined using the following formula:
α(x) =
T(x) =
The values thus calculated are entered in thetable.

5.7 Concentration measurement
The transmitter ACM-X in the S version canconvert conductivity values to concentrationvalues.
Since the relationship between concentrationand conductivity also depends on thetemperature, the conversion is performedbased on a user-defined field (threevariables: temperature, conductivity,concentration).
The calculation requires a field limited byuser-defined upper and lower limits (the8 values depicted in Fig. 5.15). The expectedmeasured values must be located in therange between the curves defined by the user(hatched area).The curve defined by the user must risemonotonically (as shown in Fig. 5.15) or fallmonotonically.
Note:
The temperature coefficient isdetermined as described in chpt. 5.6;the corresponding concentration isto be determined separately.

5.10 Calibration
This function group is used to calibrate thetransmitter. Two different types of calibrationare possible:
• Calibration by measurement in a calibrationsolution of a known conductivity.
• Calibration by entry of the exact cell constantof the conductivity sensor.
Note:
• If the calibration procedure isaborted by pressing the PLUS andMINUS keys at the same time(return to C114, C126 or C136) orif the calibration is faulty, then theprevious calibration data arereinstated. A calibration error isindicated by the “ERR” messageand flashing of the sensor symbolon the display.Repeat calibration!
• The instrument is automaticallyswitched to hold during calibration(factory setting).
