Im going out to do my first Centinel install. What do I need to know?

1. Read the Manual.2. CAUTION:When working with the Centinel with Datalogging Option (see What Centinel Do I Have below)

ensure that that the terminal marked Neutral on the Vortex GCS is the return connection and that 120VAC on theVortex is Hot. If these connections are reversed the panel may appear to function properly until an externalground is introduced to the panel (Connecting the GCS Programmer kit or a laptop serial port). This will result ina direct short from hot to ground and will damage the Vortex, and most likely the computer or GCS programmer.

3. Ensure that the Centinel surface panel is loaded with the latest matching software versions. Do this before thepanel gets to the field if possible. The latest versions as of this publication are listed below.

CIM: 2.40

Expansion I/O: 1.40

Vortex GCS (Datalogging Option): 8.30

GCS Display: 6.204. Review this FAQ, it contains information we have learned to help you deal with application specific issues. (ICS

drive interface, alarm setup, analog configuration etc)

What Centinel Surface Electronics Panel (SEP) do I have?

Any Centinel Surface Electronics Panel (SEP) contains, at a minimum, a Centinel Interface Module (CIM) and aCentinel Power Supply (CPS 902260). The Block Control Schematic in Appendix B of the manual contains detailsabout other modules in each panel. In general there are two basic flavors of SEP.

1. Centinel Interface Module (CIM) as a Controller of the CITIBus, where all CITIBus transmissions are initiatedby the CIM.2. Centinel Interface Module (CIM) as a CITIBus Module, where the CIM responds to requests for data fromsome other CITIBus Controller but is not in charge of the CITIBus traffic.

How do you tell the difference?

If there is a GCS Vortex or a GCS Electrospeed on the CITIBus that device will be the CITIBus Controllerand therefore the CIM will be a CITIBus Module (MR/SL Jumper IN).

If there is no Vortex or Electrospeed to take control of the CITIBus, then the CIM will be configured asa CITIBus Controller (MR/SL Jumper OUT).

As per Appendix B of the Manual, the CIM is a CITIBus Controller in the following part numbers:

902533 - Stand -Alone Surface Electronics Panel902534 - Stand -Alone SEP with analog output902822 - Stand -Alone SEP with Centinel 3, analog output

The CIM is a CITIBus Module in the following part numbers:902536 - Stand-Alone Dataloggable SEP with Analog902537 - Stand-Alone Dataloggable SEP with Enhanced SCADA (VCI-142)902823 - Stand-Alone Dataloggable SEP with Centinel 3, Analog Output902637 - GCS Retrofit Kit

To make a stand-alone SEP Dataloggable or give it SCADA capabilities, a Vortex GCS controller is added to theSEP to act as the CITIBus Controller, thus the CIM becomes a CITIBus Module and the MR/SL jumper is inserted

Whats with the Master / Slave jumper on the front label, it seems to be backwards?

The original drawing for the CIM label was Black on White (Left Below). This clearly illustrates that the jumper should beIN to set the Centinel Interface Module as a Slave. When the production label was made, the colors were reversed (rightbelow) and as a result the meaning of the jumper gets confusing. Consider that the small circles in both drawings are the

jumper PINS visible through the opening when no jumper is installed.

NOTE:This same issue applies to the CPS config Jumpers. Again consider the circles to be visible pins NOT covered bya jumper.

How do I configure a Centinel Interface Module (CIM) as a CITIBus Slave so it can beintegrated with a Vortex or Electrospeed GCS?

To set the CIM as a GCS Slave device, complete the following steps (Refer to pictures above and below):1. Insert the Master / Slave shunt on the front panel.2. Remove the End Of Line (EOL) shunts on the front panel.3. Check and remove the fail-safe biasing shunts directly behind the CITIBus connector INSIDE the CIM

module (requires removing the 2 screws on the lid and sliding the CIM circuit board out of its enclosure)

How do I configure a Centinel Interface Module as a CITIBus Master so it can be operatedindependently, without a Vortex or Electrospeed GCS?

To set the CIM as a GCS Slave device, complete thefollowing steps (Refer to pictures above and right):

1. Remove the Master / Slave shunt on the frontpanel.

2. Insert the End Of Line (EOL) shunts on the frontpanel.

3. If operating in electrically noisy environments,consider installing the fail-safe biasing shuntsdirectly behind the CITIBus connector INSIDE

the CIM module (requires removing the 2 son the lid and removing the CIM from itsenclosure)

How do the Centinel Analog Outputs work?

Centinel analog outputs are handled differently depending on whether your Centinel is a CITIBus Controller orCITIBus Module. (See previous question)

Centinel as a CITIBus Controller

When the Centinel is a CITIBus Controller, it is automatically programmed to send its internal Pressure andTemperatures to analog outputs IFGCS Expansion I/O modules are connected (as in 902534, 902822).

In this case the output signals will be as per the table on the Centinel Manual page 8.EIO1, Analog Out 1 = Well PressureEIO1, Analog Out 2 = Well TempEIO2, Analog Out 1 = Motor Temp (Centinel 3)

Centinel as a CITIBus Module

When the Centinel is a CITIBus Modulethe information from the Centinel is passed digitally to the GCS Vortex orGCS Electrospeed. In this case the Centinel data is equivalent to any analog in the GCS system. A GCS Vortexor Electrospeed system allows any analog value to be sent to an analog output or configured to alarm on a userdefined threshold. Configuring analog outputs and alarms follows the standard for any GCS analog, and isdocumented in the GCS Operators Manual. We explain the process specific to Centinel below.

How do I conf igure Analog Outputs to track Centinel Module data if the Centinel is a CITIBusModule?

NOTE:This procedure requires 7.20 of System Controller and 5.22 of Graphic Display software.

Select Prog Logic Funct.

Select Analog Output Control

Select an analog output in the system to configure (X1 = Expansion I/O Module 1)


5/15

Scroll thru the list (left / right arrow keys) to select the specific Centinel Data for the Analog Output and pressEnter

Example configuration for Centinel 3.

How do I conf igure USER DEFINED ALARMS for Centinel Data?

To setup a User alarm, go to the bottom right hand corner of the main menu and enter the Prog Logic Funct.screen.

Then select User Defined alarms


6/15

Once you press ENTER, youll see this screen for user alarm 1, inactive.

Press ENTER while the cursor is on DATA SOURCE and youll get this next screen.

Move the cursor to Cntl Mtr Tem and press ENTER to get the next screen.

At this point, pick Alarm Type Hi Thld, then enter your high threshold value, and set the enable/disable and timedelays the same as all other GCS alarms.

How Can I Simulate Changes in Centinel Channel Data to Test Analog Outputs or SetpointControl (PID)

The minimum reading o f a GCS analog must not be edited. The best way to simulate a range of pressuresor Temperatures from a Centinel to check the scaling of an external device (such as an ICS) is to use the offsetparameters. These are only accessible when you have Field Service Security. This is equivalent to inserting thecode enable jumper on a system control board. Since there is no jumper on the Centinel board, you will need tocreate a field service security PC Card and insert that into the display unit. Once the security card has beenrecognized, the GCS Centinel setup screen will show additional parameters as illustrated by the before and after

screen shots below.

No Code Key Access Code Key Access

To make a code key access card, simply create a file called code.kee on a PC Card and the PC Card into the GDThe file need not contain any data, so long as it is called code.kee.

Once you have these additional parameters available, use the Pres Offset parameter to experiment with yourpressure reading. It can only be adjusted between -3276.7 and +3276.8, so you cannot simulate a full 5000 PSI ifyou have less than 1724 PSI downhole. (5000-3276 = 1724psi). Be aware that the offset values you enter intothese parameters take effect only after the next full reading packet is received from down hole. That means itcould take up to 20 seconds or so for the offset value to be added to the reading. Just be sure to reset thoseoffsets to zero when you are finished testing.

If you must simulate a full 5000 PSI reading, youll have to use an I/O module that is not slaved to the Centineldevice so that you can manually adjust the output of the 4-20mA. Alternatively, you can use a commerciallyavailable current loop test box that both produces and measures a 4-20mA signal.

The Centinel stand-alone init ializes properly and displays data but the Centinel output appearsto be stuck at approximately 15 mA. (Using an outside 4-20 mA source confirms that the ICSdrive analog inputs seem to function properly.)

BOTTOM LINE: Dont mess with the Max & Config or Min Reading parameters.

This is a known software issue described in a recent tech brief (MATB 05-002) that can occur in the followingcases:

a. A Stand-alone Centinel in Datalogging configuration (c/w a Vortex GCS) has had its Analog OutputSource parameters set to Centinel channels and then at some time afterward the 'max and config'parameter OR the 'minimum reading' parameter has been changed.

b. The Centinel automatically configured the analog outputs at boot-up, but someone has modified theminimum rdng or the span and config of one of the analog output readings.

In either case the 4-20 mA output calculation is corrupted and the output value can get stuck at one specific valuetypically about 15 mA.

If the ICS has a PHD Signal Conditioner installed, this board should be removed when an analog input board orCIB is installed so that the PHD board does not interfere with the analog signals from the Centinel I/O.

The Analog Outputs from the Centinel are not accurate.

Most likely the expansion I/O module is not properly calibrated. This could have occurred because the IOM wasnot calibrated before a software upgrade or when setpoints were not reloaded previously. When loading software

version 1.30 into the IOM, the existing calibration information will be retained assuming it is valid.

Alternately, consider the FAQ below that discusses improper operation while the ICS is running.

We have a procedure for re-calibrating the IOM when it is attached to a Vortex GCS (Centinel Datalogging option)on the Controls Web Site on the GCS Software page. The IOM calibration procedure with a CIM should besimilar, though we are working on a specific procedure. Generally we would avoid calibrating IOMs in the fieldunless you have the proper 4-20 mA meter or unless no spares modules are available. For now, call us if youhave to do this and need help.

When I enter values to calibrate the Expansion I/O module, the numbers revert back to theoriginal or 0. Why cant I complete the calibration?

We have had reports that after re-loading software calibration values entered would not stay or revert back to 0.This is likely caused by reloading software in the IOM before reloading software in the GCS Vortex. As a resultthe IOM factory calibration mode (wormhole) is closed.

The solution is to reload software in the IOM a second time and then proceed with the calibration procedure.

Setpoint Control from Centinel Inputs does not function properly

This is likely a result of one of the other symptoms listed in this FAQ. Try to determine if your symptoms aresimilar to any of the others. If NOT, please contact us.

Note the following known issues with ICS software:

When the lo alarm is set at or below the zero value the drive will accelerate to the low speed clampfrequency and stay there.

If the controller enters an alarm state, it will lock the output frequency until the alarm goes away or thedrive is stopped. This was to compensate for PHDs that would have some dead spots in their operationcaused by the wiper of the pot loosing contact.

When the drive is stopped, the Centinel Data transfers to the ICS properly. Once the drive isstarted, the GCS Display updates are very slow and the ICS Analogs are not reading properly.

This symptom was discovered in our testing but may be responsible for inaccurate readings on the ICS.

It has been discovered that the electrical harmonic noise from a VSD can greatly affect CITIBus communicationsunder certain situations. Since the CITIBus communication link is a high speed RS-485 system, propertermination is required on both ends of the bus. If the terminations are not present, the system is more susceptibleto electrical noise.

Make sure that the CITIBus controller has the shunt blocks in for the termination and failsafe bias resistors. TheCITIBus controller can be:

a) a Vortex-GCS motor controller in a dataloggable stand-alone Centinel system (see Figure 1),b) a Centinel Interface module (CIM) in a non-dataloggable stand-alone Centinel system (see Figure 2),c) or a System Control board in a dataloggable Centinel system. (There are no shunt blocks for

terminations on this board. Terminations are always present).


10/15

The shunt block locations are circled in the diagrams below.

Figure 1 Vortex GCS Shunt Blocks Figure 2 Centinel Interface Module Shunt Blocks

On a typical CITIBus system with a display unit at the end of the line, the addition of just the two shunt blocks(termination resistors) provides acceptable communications. For systems without a permanent display, it isadvisable to have all shunt blocks installed.

We also found that adding a ferrite core inductor similar to those used on other cables in the ICS cabinetimproved the situation significantly. The inductor was added to the signal wires between the Exp I/O moduleanalog output and the Analog Input board. This marked improvement was witnessed when the shunt blocks onthe CITIBus controller boards were not installed.

Note 1: By default, all six (6) shunt blocks are installed for the Vortex GCS motor controller.

Note 2: By default, just the two EOL shunt blocks are installed for the Centinel Interface module. In our testconfiguration using an ICS drive, CITIBus communication with the CIM as the controller was solid with or withouta display with just the two shunt blocks providing end-of-line terminations.

My Centinel in Master mode boots up, I hear relays click 4 times but the power supply levelnever changes from 100%, then everything stops with no fault annunciation or a CentinelShort Circuit alarm. Any suggestions?

Depending on the display software version, you may need to reboot the display (see next faq)

Centinel Short Circuit alarm simply indicates that the CIM did not receive any change in signal from the down holegauge, thus no data. This could be caused by several factors.

Check the CPS Config jumpers on the CIM and ensure they are installed closest to the Bottom of the module.Similar to the MR/SL jumper FAQ above, consider the circles in the label to be pins visible and not covered by a

jumper.

Next consult the troubleshooting steps found on page 28 of the Centinel Manual (Rev 1.39)

The Centinel in Master mode boots up and starts work ing but doesnt seem to recognize thegauge. I hear relays click 4 times and then everything stops with NO error enunciated. Whatnow?

There is a known issue with Display software 5.22 when connected to a Centinel Master. In this case the alarmannunciation is only updated when the display is powered up and will not update after that time. If the Centineldoes not appear to be working and there is no indication of what is wrong, try unplugging the display and pluggingit back into the CITIBus. This will reboot the display without restarting the Centineland should allow theCentinel alarm to annunciate properly.


11/15

Next consult the troubleshooting steps found on page 28 of the Centinel Manual (Rev 1.39)

Why does my User Defined Alarm cause a low threshold shutdown on Centinel pressure eventhough the reading is above the threshold?

During the development of the Centinel there were several changes mad to the spanning capabilities forparameters and alarm trip calculations. Some parameters are spanned 0-9999, some versions were spanned -

32768 to +32767 and the latest versions span Centinel pressure 0 to 65535 for maximum resolution.

GCS products support User Definable Alarms in latest software versions accessed via the User Prog Func menu.

Problems can be encountered when combining older versions of system controller, CIM and IOM software. Werecommend you upgrade all software to the latest available versions as per the first FAQ at the top of thisdocument.

Is there any way to annunciate a high or low alarm using a digi tal output on a Centinel Stand-alone?

If the Centinel stand-alone product has the Datalogging option (comes with a GCS Vortex in the panel) it ispossible to configure a contact closure to indicate a high or low alarm condition. This is made possible bycombining two GCS features: User Alarms, and Digital Output Control.

Two configuration steps are required assuming a working Centinel SEP:

1. Configure a User Alarm with the desired Centinel data as the data source. Set the threshold as high or low,enable the Alarm and set the desired threshold.

2. Configure the Digital Output Control for the desired digital output. Select the Alarms column and scroll downto User Alarm configured in #1 (approximately 7 right key presses). Note that the name of the user alarm inthe list of alarms will have changed to the data source name.

The system will change the state of the digital output as soon as the Centinel data exceeds the user alarm

threshold. The shutdown and bypass delays on the user alarm configuration menu are not relevant because theGCS Vortex is not actually controlling a motor.


12/15

My Centinel is communicating intermittently. Is there something I can try?

Centinel software versions 2.00 and previous use an auto-ranging algorithm to determine optimal voltage to thedownhole tool. In certain applications this algorithm could select an output voltage that is right at the minimumlevel required for the gauge. This results in the gauge dropping out on an underpower situation intermittently. Itis possible to adjust the power level to the gauge using the following procedure:

1. From the main Menu select GCS Modules then Onboard I/O.2. press the right arrow key 2 times to change to theAnalog Output 1 menu.

3. increment the present value by a few percent monitoring the gauge operation.

One other source of intermittent communication to a downhole tool is an improperly calibrated CIM module. It isrecommended that the calibration information on intermittent units be checked as per the FAQ below.

How do I check the calibration of my CIM?

1. Configure the CIM as a Master (Master/Slave Jumper OUT) and supply it 24 volts.

We can get 24 volts from a CIM Auxiliary Power supply (902455 &902538). Alternately it is possible to 'steal' power from a GCS Vortex orElectrospeed by making a special cable that only connects CITIBus power and

ground from these units. +24 is on pins 7&8 of a CITIBus cable and ground is on Pins 3&4. If we take astandard CITIBus cable and cut the wires to pins 1,2,5 and 6 then there will not be any CITIBus conflicts.

2. Connect a Graphic Display.3. Insert a Code Key PC Card.

4. Navigate to the System menu and select the Diagnostics sub-menu that now appears5. In this menu select DAC Lvl:

6. The calibration values for AO1 are on line 4 in the 3rd

(min) and 4th

(max)columns. If the max value is 255, the calibration has likely beencorrupted. The other values in this table are not used in the CIM.

Is it possible to re-calibrate a CIM module as a stand-alone device:

1. Configure the CIM as a Master (Master/Slave Jumper OUT) and supply it 24 volts.

If we take a standard CITIBus cable and cut thewires to pins 1,2,5 and 6 then there will not be any CITIBus conflicts.


13/15

2. Connect a Graphic Display.3. Re-load CIM software version 2.20 or newer.4. With power disconnected, connect a 4-20 mA measurement device or a 100 ohm resistor with a voltmeter to

measure Analog output1.5. Power up the system and use the standard Factory Calibration menu on the System menu to view the Analog

Output 1 calibration menu

Select Enter, Press right arrow twice

6. Set a value in the A01 Raw parameter that causes the output to read 4 mA. Typically this is a value of 7 or 8.7. Enter the Raw value that produced 4 mA out into the Minimum Value parameter.8. Adjust the A01 Raw value again to produce a value of 20 mA output. Typically in the range of 187 to 220.9. Enter the Raw value that produced 20 mA output into the Maximum Value parameter.10.These steps should be repeated for analog output 2 (one right key press).11.Once the 4 values are entered, go back to the System menu and set Factory Calibration to NO.

NOTE: The CIM will not start it's auto-ranging algorithm unless the Enable Cal parameter is set to no.

How can I configure my Centinel to cause a shutdown if the system detects a gauge problem?

My Centinel gauge is communicating intermit tently, but I want to keep running the well. Howdo I prevent the system from shut ting down i f communication to the gauge is lost?

The parameter on the Centinel Setup menu labelled Centinel Receiver Com Alarm controls whether the systemwill cause a shutdown if the CIM looses communication with the downhole gauge. If this parameter is set to NO,

the system will annunciate the alarm condition in the alarm window but will not shut the well down or prevent itfrom being started.

My Centinel temperature is displaying as expected but the pressure is reading 0. Whats theproblem?

This is a known issue with version 2.00 of Centinel software that occurs when the pressure reading is greater than3276.7. In this case the data actually overflows a signed data type and is negative. As a result the system forcedthe value to 0.

This has been fixed in Centinel software version 2.20.


14/15

Is it possible to view the results of the auto-ranging process?

There is one CIM troubleshooting capability that may not be widely known. The CIM automatically ranges theoutput voltage to achieve the optimum signal strength from the downhole gauge. This is completed by setting theoutput voltage in 12.5% increments and measuring the maximum and minimum signal at each output level. Thenthe level where the largest difference between max & min is noted selected for operation.

It is possible to view the data collected for signal strength in the auto ranging process using the following steps:

1. The CIM must be in MASTER mode. Jumper OUT.2. Insert a Code Key PC Card (a PC Card with a code.kee file on it)3. From the main menu, select Status to view the Centinel Status menu.

4. Position the cursor over the Intake Pressure parameter and press ENTER to display the calibration menu

The calibration shows the min and max values read at the analog input (signal from Centinel gauge) for eachoutput voltage level (DAC ranges from min calibration value to max calibration value, thus 4-20 mA.

In the example above the table has been initialized to maximum and minimum values but since NO gauge wasconnected, the system never detected any signal from the CIM and never even tried to auto-range.

If the gauge was ever detected, the values in this table should be in the range of 300 to 1000 counts. Thedifference between the min an max values at each DAC Level (output voltage level) is the strength of thesignal. The DAC level of 14 above represents and output of 12%, the 40 is 25% etc up to 222 which represents100% power supply output.

Looking at this table may give us some additional information about why the re-initializers do what they do. It mayalso provide more clues to some of the non-working Centinels.

We have a GCS Electrospeed that shows invalid input voltage values but only when theCentinel is connected as a slave GCS device. What is wrong?

This is a known issue with CIM software version 2.20. When the CIM is used as a CITIBus slave along with anI/O module in an Electrospeed or Electrostart switchboard the CIM responds with invalid data which overwritesanalogs in the system controller. You may also notice that the system controller will report that an RDCM modulehas been noted on the CITIBus. (GCS Modules -> Modules Status).


15/15

The solution to this issue is to update to version 2.40 of CIM software. Also, unless there really is an RDCM inthe system, navigate to the GCS Modules-> Modules Status menu and disable the RDCM so the system does notwaste time trying to communicate with a module that is not in the system.

Weve upgraded a Centinel Interface Module with the new software revision 2.40 and now theCentinel Intake Pressure displayed 358 bar, while it has to be 35.8 bar. What should we do?

The work-around is to change the Centinel Unit setting (basic setup menu) from SI to IMP. Wait for a while andset it back to SI. This should correct the decimal problem.
