OVERVIEW OF OPERATOR INTERFACEThe compressor unit is controlled by a computer basedmachine control system. The controller continuouslymonitors the conditions and operation of the compressorunit and the various subsystems. It also directs theoperation of components.

The panel user interface is designed to allow an operatorto efficiently access and control the operation of thecompressor unit and subsystems. The control panelscreen is used to display graphic screens. By pressing akey on the keypad, the labeled or described function isrecognized by the control processor.

The following information is presented to help the operatorinteract with the graphic screens and the Quantum™compressor control panel. This manual is intended todescribe all presently available features for thecompressors listed in Compressor Model Differences.Reference this section for the differences of thecompressor models that will apply to the displayed dataand the setup and setpoint entry. If applicable is usedthroughout this manual to indicate when something mightapply. This is because of the compressor model (seeCompressor Model Differences) or because this feature oroption was selected from a setup.

COMMON TERMINOLOGY

Shutdown - A critical safety limit has been reached orexceeded and the compressor has been shutdown.

Alarm - An alarm setpoint has been reached or exceeded.The compressor will continue to run if running.

Manual - The device is being controlled from directcommands or keys at the local controller.

Auto (Automatic) - The device is being controlled fromsetpoints at the local controller.

Remote - The device is being controlled by a remotecontroller.

OPERATOR ACCESS

Operator access to this system is through various screens.A screen is the physical representation of data on thedisplay. Icons have been used to help an operator quicklyidentify functions. An icon is a small, graphic symbolrepresentation. Each screen has a title area. The title isdescriptive of the screen. The current day; date and time,is shown in this title area. The day of the week; Sundaythrough Saturday (Sun. - Sat.) is displayed. The month ofthe year from January to December (Jan. - Dec.) isdisplayed. The day of the month from 1 to 31 and the yearfrom 0001 to 9999 are displayed. The time displayed is theactual time in 24 hours (military) format. The hours,minutes, and seconds are displayed. The labeled keys onthe panel keypad provide quick access to the operator'sneeds. By pressing a labeled key on the keypad, thecorresponding function is recognized. Most of the screenshave screen keys that describe or show a function that isrecognized when the coinciding keypad key to the right ofthe screen is pressed. The screen keys provide access toother screens or commands. For easier viewing, relatedinformation is separated into boxes. The setup andsetpoint entry is separated into logical controlcomponents. Setup selection of features and options havebeen provided to prevent the operator from unnecessaryviewing and entering of unused control settings. Therequired control settings are clearly presented. To furtherassist the operator, on-line help is provided. Someselections appear faded to indicate that this feature isunavailable. A feature can be unavailable because ofsetup selections such as the compressor model. Someselections appear faded to indicate that this feature mightbe available in a future software release.

TO CHANGE SETPOINTSWARNING

The Quantum™ has the capability of being modifiedby the user/owner in order to obtain differentperformance characteristics. Any modification to thestandard default settings may have a severe negativeimpact on the operation and performance of theequipment. Any modification to these control settingsis the sole responsibility of the user/owner and Frickdisclaims any liability for the consequences of thesemodifications. It is possible that the modification ofthese settings may cause improper operation andperformance that results in property damage,personal injury or death. It is the responsibility of theuser/owner to evaluate and assess the consequencesof their actions prior to modifying the controls for thisunit.

The setpoints define the operation and limits of thecompressor unit and subsystems operation. Adjustablesetpoints are setpoints that an operator can easily changein the field. These setpoints are stored in EEPROM (non-volatile memory).

NOTE: Adjustable Setpoints are not lost after power isinterrupted. However, we suggest that a list of AdjustableSetpoints be recorded and stored safely to facilitatereentry, in case there is a need to return to the originalsettings.

1. From an adjustable setpoint screen, select the[Change Setpoints] key. This positions thecursor at the first data entry field. The selecteddata entry field can be identified by the blackbackground and white text.

2. Use the arrow keys to move the cursor to thedata entry field to be modified.

3. Having selected the setpoint to be changed, thenumerical keys and the decimal key may be usedto enter the new setpoint. Typing a new value willcompletely erase the old value.

4. To remove a typing mistake, the left and rightarrow key can be used to position the cursor onthe mistake and then use the [DELETE] key toerase it.

5. Press the [ENTER] key to input the new data inthe data entry field.

6. If the value is out of bounds, an error messagebox displays the proper value range. Press the[OK] key to acknowledge the error message.Re-enter the correct value.

7. Pressing the [Enter] key inputs the new setpointand selects the next data entry field.

8. When finished making any changes to the dataon an adjustable setpoint screen press the [OK]key to accept all changes or press the [CANCEL]key to cancel all of the data changes.

Note: When the display units are selected to display inPSIG, then an entry of a pressure value above 29.7 isassumed to be PSIG. An entry less than or equal to 29.7will cause a message box to appear after pressing the[ENTER] key. This message prompts the operator toselect the unit of measure. The operator must select eitherthe [HG] or the [PSIG] key.

• Suction Pressure Mode 1• Suction Pressure Mode 2

• Process Temperature Mode 1• Process Temperature Mode 2• Discharge Pressure Mode 1• Discharge Pressure Mode 2• User Selectable Control Mode 1• User Selectable Control Mode 2

Following is an example of a Capacity Control setpointscreen:

Suction Pressure Control

The following setpoints are required for each of theCapacity Control setpoint screens:

Capacity Control - This setpoint is used to controlthe loading and unloading of the compressor when

the Slide Valve Position is in the Automatic (AUTO)mode.

The Proportional Band setpoint determines a range ofCapacity Control values where pulsed output is used.


Beyond the proportional band the output is continuouslyenergized. The length of time the output will be pulsed onis proportional to the distance the actual reading is fromthe Capacity Control setpoint. The further the distancefrom setpoint, the longer the output is pulsed on and theshorter the output is off. The closer the distance tosetpoint, the shorter the output is pulsed on and the longerthe output is off. If the actual reading is midpoint fromsetpoint, the output is on and off an equal amount of time.

Upper Proportional Band - A band, measured in theunits of the Capacity Control setpoint, above theupper dead band, where proportional load control isused. If the actual reading rises into this proportionalband, the load output will be pulsed as explainedabove in the description about proportional band.

Lower Proportional Band - A band, measured in theunits of the Capacity Control setpoint, below the lowerdead band, where proportional unload control is used.If the actual reading falls into this proportional band,the unload output will be pulsed as explained above inthe description about proportional band. Upper Dead Band - A band, measured in the units ofthe Capacity Control setpoint, above the setpoint atwhich the compressor will neither load nor unload.

Lower Dead Band - A band, measured in the units ofthe Capacity Control setpoint, below the setpoint atwhich the compressor will neither load nor unload.

The Cycle Time setpoint determines the amount of timethe output is on and off, when in the proportional band. Atthe completion of the cycle time the actual reading andnecessary response is re-evaluated. If a four secondperiod is selected, then the following will result:

Proportional DistanceActual Reading is From

Setpoint

OutputPulsed On(seconds)

Output Off(seconds)

0 0 41/4 1 31/2 2 23/4 3 11 4 0

Upper Cycle Time - This setpoint determines theamount of time in seconds that the load output is onand off, when in the upper proportional band. Referto the above description about cycle time.

Lower Cycle Time - This setpoint determines theamount of time in seconds that the unload output ison and off, when in the lower proportional band.Refer to the above description about cycle time.

Start Autocycle - The compressor is started at thissetpoint when it is under automatic control.

Stop Autocycle - The compressor is stopped at thissetpoint when it is under automatic control.

Start Time Delay - The minimum time in minutesthat the actual Capacity Control value must equal orexceed the start autocycle (automatic cycling)setpoint before the compressor will start. This timerhelps prevent cycling a compressor on and off due toshort or sudden changes in load within therefrigeration system.

Stop Time Delay - The minimum time in minutesthat the actual Capacity Control value must equal orexceed the stop autocycle (automatic cycling)setpoint before the compressor will stop. This timerhelps prevent cycling a compressor on and off due toshort or sudden changes in load within therefrigeration system.

Motor Control

The following information should be recorded from themotor nameplate:

• Motor Amps• Volts• Service Factor - Note: Not required if using RAM

DBS.• Horse Power• CT Factor - The Current Transformer Factor is

printed on the current transformer in thecompressor motor starter. Note: Not required ifusing RAM DBS.

To verify that the CT has been sized properly,use the following equation:

CTF = FLA (Full Load Amps) x Service Factor x1.1 = Recommended CT (Round up to nexthighest 100 Amps)

EXAMPLE: FLA = 182 Amps SF = 1.0 CTF = (182 x 1.0 x 1.1) = 200.2 > Round up to 300 [use 300:5 CT]

The following setpoint is required for safe motor operation:

Recycle delay - Each time the compressor is started,this value will be loaded into the Recycle Delay timer.This time must elapse prior to allowing thecompressor to restart. The timer will time out while thecompressor is running or stopped since the RecycleDelay is a start-to-start protection.

Overview of the Oil Pump Operation

A Prelube Pump is turned on if the Slide Valve is too high.While the compressor is running the Prelube Pump isturned off. A Full Time Pump is always turned on while thecompressor is starting and running. The Cycling Pump iscycled on and off while the compressor is running in

response to the pressure differential calculation. Thedifferential equals the Discharge Pressure reading minusthe Suction Pressure reading. The pump is turned on if[Discharge – (1.4k * Suction)] < 35. The pump is turned offif [Discharge – (1.4k * Suction)] > 45.

During the compressor stop cycle, the Oil Pump is usedfor a postlube operation that is performed to help unloadthe Slide Valve. During the postlube, the Oil Pump will beturned on for five (5) minutes or until the Slide Valve isunloaded to or below the Highest Slide Valve position toallow starting the compressor setpoint. The compressorcan not be restarted unless the Slide Valve is less than theHighest Slide Valve position to allow starting thecompressor setpoint. If the Slide Valve does not unloadbelow this setpoint within 5 minutes, the alarm messageCompressor Unload Failure - Alarm is issued.

Dual Pumps are enabled in Factory Setup. The lead pumpis the pump selected to be the first pump to run. If the leadpump has a pump auxiliary failure, an alarm message isissued and the other pump will be turned on. If thecompressor has a Low Oil Pressure Alarm failure, thesecond pump will be turned on; then after a 30 secondsdelay, the lead pump will be turned off. If while thecompressor is running the second pump has an auxiliaryfailure or low Oil Pressure is encountered, a shutdownmessage and action is issued.

Setting up a PID Channel

NOTE: The basic steps in setting up a device for PIDcontrol is:

1. Setup Input channel

• First, decide which physical input channelyou will be using. As an example, if youwanted to use Suction Pressure, lookthrough the wiring diagram, and locate theSuction Pressure input channel number(channel 9). Note: If you wish to use anAuxiliary Analog channel, it will requirebeing completely setup as its ownchannel before attempting the remainderof this procedure.

• Although we are setting up the inputparameters for the PID, we need to accessthe Output Setup to do this. Call up theAnalog Output Setup screen. To locate thisscreen, from the Operating Status screen,press [Menu], then [Calibration], andanswer the Warning message with [OK].Next, press the [More…] key, then [AnalogOut Calibration].

• On this screen, you can assign the PID toeither Analog 1 or 2 (Note: Analog Outputs 1and 2 are reserved for physical analog board# 1, and Analog Outputs 5 and 6 arereserved for physical analog board # 2). Forthis example, Suction Pressure inputchannel is 9 and is located on analog board# 1, therefore, we are free to use eitherAnalog Output 1 or 2. For this example, wewill use Analog Output 1.

• Press the [Calibration Setpoints] key. Thetop box will be highlighted in the column thatis labeled as Input Channel to Output. Thisbox corresponds to Analog Output 1, whichis the one that we wish to use. Enter a [9](for the channel number) into this box, andpress the [OK] key.

• The value to the immediate right of this box(in the Input column), will display the actualvalue that the device attached to channel 9is reading. The Output column ismeaningless at this point.

2. Setup Output parameters

NOTE: This step will normally never needsetting up, as the factory default values arepreset to work for most applications. Ifhowever, these values must be modified, useextreme care. If not properly setup, unreliableresults could occur.

• Press the [Analog 1 Out Calibration] key.Notice that a new screen appears. This iswhere you can assign a Top End Value, aBottom End Value, and an Offset. The text atthe bottom of this screen helps to definethese fields. When finished entering data on


this screen, press the [Previous Screen]key.

3. Setup PID parameters

• From the Operating Status screen, pressthe [Menu] key. Next press the [CapacityControl], then [More…]. Finally, press the[PID Setup] key.

• On the PID Setup screen, press the key thatis adjacent to the Analog channel that hasalready been set up, in this case, channel 1.

• It is on this Setup screen that the remainderof the PID parameters are entered. For adetailed description of these parameters,refer to the Overview to Tuning a PIDController.

Note: After having performed the above setup procedure,if any portion of step 1 or 2 must be changed, then repeatthe entire procedure to ensure that all parameters arecorrect per the new settings. Also, be aware that eachdevice that is utilized for PID control must also be properlycalibrated.

Overview to Tuning a PID Controller

The purpose of this section is to give some basicguidelines for tuning Proportional, Integral, and Differentialgains of a PID controller. To tune a PID controller, it wouldbe advantageous to hook the system up to some testequipment to allow you to record the appropriatevariables. At the very least, the appropriate data will haveto be monitored and recorded by hand from the systemscreen for subsequent evaluation and possiblespreadsheet graphing.

Differential Gain

Once ready, set all gains to zero (Proportional, Integraland Derivative). If you suspect that you will not needdifferential control, then skip down to the paragraph thatdiscusses the Proportional Gain. Otherwise, start byadjusting the Differential Gain. You cannot use Differentialcontrol alone the way that the software is coded, so setthe Proportional Gain to some small value (one or less).Check to see how the system works. If it oscillatesProportional Gain, you should be able to cure it withDifferential Gain. Start with about 100 times moreDifferential Gain than Proportional Gain. Now, startincreasing the Differential Gain until you see oscillation,excessive noise, or excessive (more than 50%) overshoot.Note that the oscillation from too much Differential Gain ismuch faster than the oscillation for not enough DifferentialGain. A good strategy is to push the Gain up until thesystem is on the verge of oscillation, then back the Gainoff by a factor of two or four. At this point, your system willprobably be responding very sluggishly, so it is time totune the Proportional and Integral Gains.

Proportional Gain

If it isn't already, set the Proportional Gain to a startingvalue between 1 and 100. Your system will probably eithershow terribly slow performance, or it will oscillate. If you

see oscillation, drop the Proportional Gain by factors ofeight or ten until the oscillation stops. If you don't see0scillation, increase the Proportional Gain by factors ofeight or ten until you start seeing oscillation or excessiveovershoot. As with the Differential Controller, a goodstrategy is to tune right up to the point of too muchovershoot, then reduce the Gain by a factor of two or four.Once you are close, fine-tune the Proportional Gain byfactors of two until you like what you see.

Integral Gain

Once you have the Proportional Gain set, start increasingthe Integral Gain. Your starting values will probably befrom 0.0001 to 0.01. Here again, you want to find therange of Integral Gain that gives you reasonably fastperformance, without too much overshoot, and withoutbeing too close to oscillation.

Proportional Only Control

There will be certain applications in which onlyproportional control is required for good performance.When this is the case, the Integral and Differential Gainscan simply be set to zero, and the Proportional Gain set toa calculated value. An example will help clarify how theProportional Gain can be calculated to producepredictable results:

Suppose you wish to control the Suction Pressure toa setpoint of 50 PSIA, and you want the output to be100% when the measured value us 35 PSIA (andbelow), and you want the output to be 0% when themeasured value is 50 PSIA (and above).

Let the term PB represent the Proportional Band, andPG represent the Proportional Gain that you wish tocalculate. Also, let the term R represent the Range ofthe particular sensor. Then, if the input channel is setfor 1-5 Vdc use PG = (1.25 x R) / PB, if the inputchannel is set for 0-5 Vdc, use PG = R/PG. In theseexamples, the Proportional Band is 15 (50 - 35). TheRange of a Suction Pressure sensor is 0 - 200 PSIA.Therefore, PG = (1.25 x 200) / 15 = 16.66. Since onlyinteger values are used by the Quantum™ control forgain factors, 17 would be entered for the ProportionalGain. Because of this roundoff, the output will reach100%, close to but not exactly at 35 PSIA.

In this example, the Action of the control loop shouldbe set to Reverse (the further the measured value isbelow the Setpoint, the higher the Output). If theopposite is desired in a particular control loop (thefurther the measured value is above the Setpoint, thehigher the Output), then the Action should be set toForward.

PB = 1.25 R PG


Digital Output #18 Control

Condenser Control

The Condenser Control screen is shown if a type ofCondenser Control was selected in Panel Setup. Onlythe setpoints of the selected Condenser Control will show.Sequence set points are based on the system DischargePressure, analog channel 11. An additional pressuresensor for system discharge is required. The dischargelevel the condensers are operating on has its ownpressure to maintain. The control system maintainsDischarge Pressure by sequencing the condenserdevices. Digital control is used to turn on and off thecondenser digital outputs. Analog control is used to varythe analog signal of the condenser analog output.

This setpoint is required for both Digital Control andAnalog Control:

Condenser Control Setpoint - This is used to controlthe sequencing on and off of the condenser digitaloutputs and/or the signal strength of the condenseranalog output.

A Digital Control data box is shown if digital control isselected. The status of the condenser outputs is shown:

On - This output is energized.

Off - This output is de-energized.


Disabled - A zero (0) has been entered for thesequence order, which disables this output from beingturned on.

The digital control settings on this screen are useful forsequencing condenser fans and pumps. The following setpoints are required:

Upper Dead Band - A Discharge Pressure bandabove the Condenser Control setpoint at which thecondenser digital outputs will neither be turned on orturned off.

Lower Dead Band - A Discharge Pressure bandbelow the Condenser Control setpoint at which thecondenser digital outputs will neither be turned on orturned off.

Upper Delay- The minimum time in seconds that thesystem Discharge Pressure must be at or above theCondenser Control setpoint plus the upper dead bandbefore an output is turned on. This timer is used toallow the system to respond to the change in theamount of condensing. If the pressure falls below thispressure for any reason at any time, the start timedelay will be reset to start counting again if needed.

Lower Delay - The minimum time in seconds that thesystem Discharge Pressure must be at or below theCondenser Control setpoint, minus the lower deadband before an output is turned off. This timer is usedto allow the system to respond to the change in theamount of condensing. If the pressure rises abovethis pressure for any reason at any time, the start timedelay will be reset to start counting again if needed.

Sequence Order - A number will indicate the order inwhich the condenser output is turned on. Sequencingstarts from 1, and goes up in numerical order.Stopping of condenser devices is in reverse order ofthe starting. The number zero (0) should be enteredto disable that device from being sequenced on. Acondenser output that is given a zero (0) will beimmediately turned off. The following condenseroutputs require a setpoint for a sequence position:

• Condenser Output #1• Condenser Output #2• Condenser Output #3• Condenser Output #4 - If digital control is

selected, this output is sequenced using thedigital control setpoints. When analog controlis selected, the output is coupled with theanalog output.

An Analog Control data box is shown if analog control isselected. The status of condenser output #4 is shown inthe analog data box along with the relative percent valueof the analog output signal.

The following analog control settings are required:

Upper Dead Band - A Discharge Pressure bandabove the Condenser Control setpoint at which thecondenser analog output signal will neither beincreased or decreased.

Lower Dead Band - A Discharge Pressure bandbelow the Condenser Control setpoint at which thecondenser analog output signal will be neitherincreased or decreased.

Response Time - A response time of 1 to 20 refers tothe relative time in seconds it takes to raise theanalog signal to its maximum output if the systemDischarge Pressure is greater than or equal to theCondenser Control setpoint plus the analog controlupper dead band. The response time is also used asthe relative time in seconds it takes to lower theanalog signal to its minimum output if the systemDischarge Pressure is less than or equal to theCondenser Control setpoint minus the analog controllower dead band. A response time of 1, is the slowestand 20 is the fastest.

A toggle key is provided that changes when the condensercontrol is active:

[Condenser Active Always] - Selects the CondenserControl to be active always even when thecompressor is not running.

[Condenser Active Running] - Selects theCondenser Control to be active only when thecompressor is running.

[Not Active] - Selects the Condenser Control to becurrently not active.

Digital Condenser Control

The following is a description of the Condenser Controllogic when only digital condenser control is enabled.

If the System Discharge Pressure is above thecondenser control setpoint the following is repeateduntil all condenser outputs are turned on:

• If the System Discharge Pressure continues torise and is greater than or equal to theCondenser Control setpoint plus the digitalcontrol upper dead band, then the nextcondenser output is turned on. When acondenser output is turned on, the upper delaytime is used to set a timer that must time outbefore the next condenser output will be turnedon.

If the System Discharge Pressure is below theCondenser Control setpoint the following is repeateduntil all condenser outputs are turned off:

• If the System Discharge Pressure continues tofall and is less than or equal to the CondenserControl setpoint minus the digital control lowerdead band, then the last condenser output that ison, is turned off. When a condenser output isturned off, the lower delay time is used to set atimer that must time out before the nextcondenser output will be turned off.


Analog Condenser Control

The following is a description of the Condenser Controllogic when only analog Condenser Control is enabled.

If the System Discharge Pressure is above the CondenserControl setpoint:

• If the System Discharge Pressure is greater thanor equal to the Condenser Control setpoint plusthe analog control upper dead band, thencondenser output #4 is turned on (if it is notalready on) and the analog output signal isincreased using the response time.

If the System Discharge Pressure is below the CondenserControl setpoint:

• If the System Discharge Pressure continues tofall and is less than or equal to the CondenserControl setpoint minus the analog control lowerdead band, then the analog output signal isdecreased using the response time. When thesignal reaches its minimum output, condenseroutput #4 is turned off.

Digital and Analog Condenser Control

The following is a description of the Condenser Controllogic when digital and analog Condenser Control isenabled:

If the System Discharge Pressure is above theCondenser Control setpoint, the following is repeateduntil all condenser outputs are turned on:

• If the System Discharge Pressure is greater thanthe Condenser Control setpoint, plus the DigitalControl Upper Dead Band for the Upper Delayperiod of time, the first output is turned on. If the

System Discharge Pressure remains high foranother Upper Delay period of time, the secondoutput is turned on. This continues until all theavailable outputs are turned on, or the SystemDischarge Pressure drops below the ControlSetpoint plus the Upper Deadband.

• In addition, after Condenser Output #4 is turnedon, the analog output signal begins to increase.This continues as long as the System DischargePressure is greater than the Condenser Controlsetpoint plus the Analog Control Upper DeadBand. After Condenser Output #4 turns on,additional digital outputs will not turn on until theanalog output signal reaches 100%. The rate atwhich the analog output signal increases, ordecreases, is determined by the Response Time.

If the System Discharge Pressure is below theCondenser Control setpoint the following is repeateduntil all condenser outputs are turned off:

• If the System Discharge Pressure is less than theCondenser Control setpoint minus the AnalogControl Lower Dead Band, the analog outputbegins to decrease. After the analog outputsignal reaches 0%, it the System DischargePressure has been less than the CondenserControl setpoint minus the Digital Control LowerDead Band for the Lower Delay period of time,the last output is turned off. If the SystemDischarge Pressure remains low for anotherLower Delay period of time, the second output isturned off. This continues until all the outputs areturned off, or the System Discharge Pressurerises above the Control Setpoint minus the LowerDeadband.


Compressor Sequence Control (MODE 1)

This screen is shown if the Sequence Mode 1Compressor Sequencing option was selected in PanelSetup. For quick access to this screen there is a[Compressor Sequence Setpoints] screen key on theOperating Status -2 screen. This sequencing is intendedfor compressors that are operating to maintain the sameCapacity Control setpoint. The settings on this screen areused to sequence the compressors when a compressor isin the remote start mode of operation and in remote SlideValve mode and available to run i.e. not in shutdown(cutout) or Recycle Delay. This sequence control is onlyused for compressors with a variable Slide Valve and willwork with existing Frick RWB, RXB, and RXF panels.Serial communication using the Com-1 port is used for thissequencing (drawing nos. 640A0042 and 640A0050.

The setpoints that are currently being used for CapacityControl are only shown here for referencing. Thesesetpoints are taken from the active Capacity Controlsettings at the panel where Compressor Sequencing isactivated. Current Value is the current reading or actualreading of the pressure or temperature process variablethat was chosen as the Capacity Control method.Compressor Sequencing can be enabled from panel setupand entered on more than one panel. However; for propercontrol, only the Compressor Sequencing settings at onepanel should be made active. The following describes howCompressor Sequencing uses the Capacity Controlsetpoints:

Capacity Control - This is the reading that the controlsequence will attempt to maintain for the indicatedprocess. This setpoint is used to control the loadingand unloading of the compressors. The Proportional Band setpoint determines a range ofCapacity Control values where proportionally timedpulsed output is used. Beyond the proportional bandthe output is continuously energized. The length oftime the output will be pulsed on is proportional to thedistance the current reading of the process variable is

from the Capacity Control setpoint. The further thedistance from setpoint, the longer the output is pulsedon and the shorter the output is off. The closer thedistance to setpoint, the shorter the output is pulsedon and the longer the output is off. If the actualreading is midway from setpoint, the output is on andoff an equal amount of time. (See Cycle Time).

Upper Proportional Band - A band, measuredin the units of the Capacity Control setpoint,above the upper dead band, where proportionalload control is used. If the actual reading risesinto this proportional band, the load output will bepulsed as explained above in the descriptionabout proportional band.

Lower Proportional - A band, measured in theunits of the Capacity Control setpoint, below thelower dead band, where proportional unloadcontrol is used. If the actual reading falls into thisproportional band, the unload output will bepulsed as explained above in the descriptionabout proportional band.

Upper Dead Band - A band, measured in theunits of the Capacity Control setpoint, above thesetpoint at which the compressor will neither loadnor unload.

Lower Dead Band - A band, measured in theunits of the Capacity Control setpoint, below thesetpoint at which the compressor will neither loadnor unload.


The Cycle Time setpoint determines the amount of timethe output is on and off, when in the proportional band. Atthe completion of the cycle time the actual reading andnecessary response is re-evaluated. If a 4 second periodis selected, then the following will result:

Proportional DistanceActual Reading is

From Setpoint

OutputPulsed On(Seconds)

Output Off(seconds)

0 0 41/4 1 31/2 2 23/4 3 11 4 0

Upper Cycle Time - This setpoint determines theamount of time in seconds that the load output is onand off, when in the upper proportional band. Refer tothe above description about cycle time. Lower Cycle Time - This setpoint determines theamount of time in seconds that the unload output ison and off, when in the lower proportional band.Refer to the above description about cycle time.

Start - A compressor is started at this setpoint. This isthe Start Autocycle setpoint of the active CapacityControl. A compressor is started at this setpointduring Compressor Sequencing.

Stop - A compressor is stopped at this setpoint. Thisis the Stop Autocycle setpoint of the active CapacityControl. A compressor is stopped at this setpointduring Compressor Sequencing.

The load limiting setpoints are used if no compressors arerunning and the equalized system is to be slowly pulleddown to normal. These setpoints limit the compressorloading when starting the first compressor:

Slide Valve Position - the Slide Valve position setpoint that the control system will hold the Slide Valveuntil the duration timer has timed out.

Duration Time - the amount of time in minutes tohold the compressor at the Load Limiting Slide ValvePosition setpoint. If load limiting is not desired, set thistime to zero (0).

When the first compressor is started, thesequence will allow that compressor to load up tothe Slide Valve Position setpoint and hold thecompressor at this setpoint until the DurationTime has timed out or the current reading of theprocess variable falls below the Start setpoint.

The following set points are required for each compressoron the suction level:

(A - D) Compressor ID - A through D represent thesequence position. Any machine can be set for anysequence position. The letter determines the startingorder of the compressors, position A is the firstposition. If the Start setpoint is maintained, the lead orfirst machine started, will always load up first and thenthe next sequence position on up as they are needed.The stopping of compressors is done in the reverse

order of the starting. Each compressor must have aunique ID# entered at their control panel. A zero (0)disables or removes a compressor ID from beingsequenced.

Unload Minimum Slide Valve Position - This is theSlide Valve position a compressor will be allowed tounload to. The compressors will unload to theminimum Slide Valve position for that machine, whenthe reading is below the Capacity Control lowerdeadband. This set point is only used if more thanone compressor is running. When only onecompressor is running it is allowed to fully unload.This set point can prevent short cycling ofcompressors in the unload sequence. Short cyclingoccurs when a compressor is stopped and the currentreading quickly rises and an already runningcompressor is unable to compensate because it isrunning at full load, so a compressor is cycled backon very shortly after a compressor was stopped. Ascrew compressor has some minimum built-incapacity that cannot be shed, generally in the rangeof 10-15% of full load capacity, when the compressoris stopped the control system needs to compensatefor this loss. If a compressor that is running at full loadis allowed to unload to a minimum Slide Valveposition, this compressor will then be able tocompensate for the extra load that occurs whenanother compressor is stopped.

The computer will not unload a compressor below thisset point during normal system operation. Forexample, if compressor A is running at 100 %capacity and compressor B is running and has beenunloaded to the minimum Slide Valve position, B isstill contributing somewhat to the capacity. To take Boff line would be to lose approximately 10% of thetotal capacity. If A was already loaded to 100%capacity, it would not be able to load to compensatefor losing the 10% B dropped off. The current readingwould rise and B would be cycled on again. If thecurrent reading remains low (below the lowerdeadband) for the predetermined time (stop timedelay), B will then stop. A will have sufficient reservecapacity to maintain the loss of B. The control of thisset point is in percentage of Slide Valve, notcompressor capacity. With some experimentation, it ispossible to find the right value for the minimum SlideValve position set points that neither under-compensate for the built-in capacity, resulting in shortcycling of the compressors, nor over-compensates forthe built-in capacity, resulting in inefficient operation(where the sum of the capacity of the compressorsthat are running is significantly less than the full loadcapacity of the next compressor in the unloadsequence).

Start Time Delay - The minimum time in minutes thatthe current reading must be at or above the Startsetpoint before a compressor will start. This timerhelps prevent cycling compressors on and off due toshort sudden changes in load within the system. If thecurrent reading falls below the Start setpoint for anyreason at any time, the start time delay will be reset tostart counting again if needed. When a compressor isstarting, the start time delays will be reset to startcounting again if needed for a next compressor.


Stop Time Delay - The minimum time in minutes thatthe current reading must be at or below the Stopsetpoint before a compressor will stop. This timerhelps prevent cycling compressors on and off due toshort sudden changes in load within the system. If thecurrent reading rises above the Stop setpoint for anyreason at any time, the stop time delay counter will bereset to start counting again if needed. When acompressor is stopping, the stop time delays will bereset to start counting again if needed for a nextcompressor.

Minimum Run Time - The minimum time in minutesthat the compressor must run before it is allowed tostop. This time should be as long as the RecycleDelay time. If the compressor has run out its RecycleDelay time and is turned off it will still be available torun as soon as required.

A toggle key is provided for compressor sequencing:

[Activate] - Selects the compressor control to becurrently active.

[De-Activate] - Selects the compressor control to becurrently not active.

Note: Only 1 panel should have CompressorSequencing active.

Compressor Sequence Status

The active Capacity Control setpoints and CapacityControl reading are only shown here for referencing.

The following data is displayed for each compressor to besequenced:

Slide Valve % - The actual % reading of the SlideValve position. Slide Valve Status - One of the following could beshown:

• Load - Indicates the compressor is beingtold to load.

• Unload - Indicates the compressor is beingtold to unload

• Idle - Indicates the compressor is neitherbeing told to load or unload.

Note: The displayed status does not necessarilyreflect the current solenoid status.

Sequence Status - One of the following text stringscould be shown:

• Off in Remote Start

• Off in Manual Start

• Off in Autocycle StartOff in Recycle Delay

• Shutdown

• Running in Remote Start

• Running in Manual Start

• Running in Autocycle Start

• Not Communicating

• Not in Remote Start

• Slide Valve not in Remote

• Unable to Start

• Starting

Compressor Sequence Overview (Mode 1)

The above settings are used to sequence the selectedcompressors. Only a compressor that is in both remotecompressor mode and remote Slide Valve mode will bestarted, stopped, loaded or unloaded using this sequencecontrol. If one of these compressors is failed, shutdown(cutout), in Recycle Delay, or unable to communicate, thatcompressor will be skipped and the next compressor inthe sequence (if there is one) will be controlled.

Compressor Sequencing allows for staging thecompressors in an energy efficient method and providing asmooth transition from one compressor to another, whilealso giving operator flexibility.

The deadband determines how quickly the system willrespond to a change in the process. For an example, abooster compressor might have a deadband of 0.5 PSIGfor a quicker response than the high stage compressorwith a deadband of 1.0 PSIG.

The proportional band and the cycle time determine howsmoothly the compressor loads or unloads, and can beused to prevent overshooting the process setpoint.

Lowering the Unload Minimum Slide Valve Positionsetpoint, or lengthening the Stop Time Delay, orlengthening the Minimum Run Time can be used toprevent a compressor from cycling off and on too quickly.

The refrigeration load refers to the demand for loading ofcompressors to reduce the rise in capacity that hasresulted from an increased need for refrigeration in theplant. When the load rises this means the capacity hasrisen. When the load falls this means the capacity hasfallen. Compressors need to load if the Current Value isgreater than or equal to the Capacity Control setpoint plusthe Upper Dead Band setpoint and they need to beunloaded if the Current Value is less than or equal to theCapacity Control setpoint minus the Lower Dead Bandsetpoint.

When starting a compressor, a start command is sent fromthe panel that has Compressor Sequencing activated tothe selected compressor every 30 seconds for 3 minutes.Should the compressor not start in that time period, thesequence status message Unable to Start is shown. If thisoccurs, the next compressor in the sequence (if there isone) will be sent the start command when it’s Start Delaytimes out. The Unable to Start message will clear after atime delay. The time delay is based on the worst casesituation which requires 3 minutes for each availablecompressor. If there are 4 compressors, the delay will be12 minutes. When this message is cleared, thecompressor is again available for sequencing.


The following is an example of sequencing compressors:

On System Start-up - The first available compressorin the order of A, B, C and D will start if the capacity isgreater than or equal to the Start setpoint for it’s StartDelay time period. If A is not available then B will startwhen it’s Start Delay has timed out. If B is notavailable then C will start when it’s Start Delay hastimed out. If C is not available then D will start whenit’s Start Delay has timed out.

On an initial or cold start-up (no compressors arerunning) and Load Limiting has been enabled, thenthe first compressor started will load to the LoadLimiting Slide Valve Position setpoint and remainthere until the Load Limiting Duration Time has timedout or until the current reading of the process variablefalls below the Start setpoint.

Load Rises - If the current reading continues to begreater than or equal to the Capacity Control setpointplus the Upper Dead Band setpoint, then the firstcompressor in the order of A, B, C, and D that isrunning will be loaded to 100%, followed by the nextrunning compressor in the sequencing. When at100%, the load signal will be sent to that compressorevery minute to insure the compressor remains fullyloaded.

If all running compressors are loaded greater than90% slide valve position, then the next availablecompressor in the order of A, B, C, and D will bestarted if the current reading of the process variable is

greater than the Start setpoint for it’s Start Delay time.

Load Falls - If the current reading of the processvariable falls to or below the Stop setpoint, then thelast compressor in the order of A, B, C, and D that isrunning will be unloaded to its Min. Slide ValvePosition setpoint, followed by the next runningcompressor in reverse sequencing. For example, if Aand B are running, B is unloaded to it’s Min. SlideValve Position setpoint and then A is unloaded to it’sMin. Slide Valve Position setpoint.

Only the last two running compressors may unload totheir Min. Slide Valve Position setpoint while anyother running compressor will remain loaded. If arunning compressor drops below its Min. Slide ValvePosition setpoint it will be given a load pulse every 15seconds to bring it back to the Min. Slide ValvePosition. If more than one compressor is running andthe compressors have unloaded to their Min. SlideValve Position setpoint, then the last compressor inthe sequence will be stopped if the Current Value isless than the Stop setpoint for the Stop Delay timeand the compressor has run for longer than it’s Min.Run Time setpoint.

If only one compressor is running, then thiscompressor may unload completely and stop whenthe current reading of the process variable is lessthan the Stop setpoint.


Compressor Sequence Control (MODE 2)

This screen is shown if the Compressor Sequencing Mode2 option was selected in Panel Setup. This option is notapplicable for standard Frick products. It is only availablefor Gram compressors. Compressor Sequencing setpointsare based on the suction level that the compressors to besequenced are operating on. The compressors must be onthe same suction level because each suction level has itsown settings to maintain. The settings on this screen areused to sequence the compressors when a compressor isin the remote mode of operation and in remote Slide Valvemode and not in shutdown. This sequence control is onlyused for compressors with a variable Slide Valve. Thepanels selected for compressor sequence control mode 2must be connected via the proper hardware connection.

Compressor Sequence StatusThe active capacity control setpoints and Capacity Controlreading are shown here for referencing.

The following data is displayed for this compressor:

Sequence Control:

• Activated - This compressor is beingcontrolled from the Compressor SequencingMode 2 control logic.

• De-Activated - This compressor is not beingcontrolled from the Compressor SequencingMode 2 control logic.

Control Type:

• Master - The panel is selected as the Masterfor compressor sequencing control. TheMaster is able to control one or moresubsequent Slaves.

• Slave - This panel is selected as a Slave forcompressor sequencing control. The Slaveswill be controlled by the setpoint of theMaster.

Slide Valve Pos. - The actual % reading of the SlideValve position.

Slide Valve Status - One of the following could beshown:

• Load - Indicates the compressor is beingtold to load.

• Unload - Indicates the compressor is beingtold to unload.

• Idle - Indicates the compressor is neitherbeing told to load or unload.

Sequence Status - One of the following text stringscould be shown:

• Off in Remote Start

• Off in Manual Start

• Off in Autocycle Start

• Off in Recycle Delay

• Shutdown

• Running in Remote Start

• Running in Manual Start

• Running in Autocycle Start

• Not in Remote Start

• Slide Valve not in Remote

Output Status (Digital Board 2):

• Start (Output 1) - This output is energized tosignal the next panel to start the compressor.This output is de-energized to signal the nextpanel to stop the compressor.


• Capacity Up (Output 2) - This output isenergized to signal the next panel to load thecompressor.

• Capacity Down (Output 3) - This output isenergized to signal the next panel to unloadthe compressor.

• Slide Valve > Minimum (Output 8) - Thisoutput is energized to signal the previouspanel that the Slave’s slide valve reading isabove the Minimum Capacity when Runningsetpoint.

Input Status (Digital Board 2):

• Start (Input 5) - This input is energized tosignal this panel to start the compressor.This input is de-energized to signal thispanel to stop the compressor.

• Capacity Up (Input 6) - This input isenergized to signal this panel to load thecompressor.

• Capacity Down (Input 7) - This input isenergized to signal this panel to unload thecompressor.

• Slide Valve > Minimum (Input 4) - Thisinput is energized to signal this panel thatthe Slide Valve reading of the nextcompressor is above that panel’s MinimumCapacity when Running setpoint.

The active capacity control setpoints are shown here forreferencing. The active Capacity Control setpoints aretaken from the Capacity Control settings at this panel.Actual is the current reading of the pressure ortemperature that was chosen as the Capacity Controlsetpoint. For proper control, only one panel should beselected as the Master for compressor sequencing. TheMaster compressor sequence controller attempts tomaintain the Capacity Control setpoint by loading andunloading in response to the following capacity controlsetpoints. The Slave compressor sequence controller issignaled from a previous panel to load or unload and thenuses the following Capacity Control setpoints to determinewhen to pulse the panel’s local Slide Valve load and SlideValve unload outputs. The signal for loading or unloadingfrom the previous panel overrides the Slave’s CapacityControl settings that might be determining the oppositelocal Capacity Control. For example, the Slave’s localsettings could indicate it should be loading but a signalfrom a previous panel could be telling it to unload. In thissituation, the Slave will unload but it will pulse according toits local settings. The Slave’s local settings are used todetermine pulse loading or unloading and if these settingsdon’t coincide with the Master’s settings, then improperpulsing can result. For good Capacity Control, it isimportant that each panel is properly setup. The followingdescribes the compressor sequencing Capacity Controlsetpoints:

Capacity Control - This is the reading which theMaster compressor sequence controller will attempt to

maintain. This setpoint at each panel is used tocontrol the loading and unloading of the compressor.

The Proportional Band setpoint determines a range ofcapacity control values where pulsed output is used.Beyond the proportional band the output is continuouslyenergized. The length of time the output will be pulsed onis proportional to the distance the actual reading is fromthe Capacity Control setpoint. The further the distancefrom setpoint, the longer the output is pulsed on and theshorter the output is off. The closer the distance tosetpoint, the shorter the output is pulsed on and the longerthe output is off. If the actual reading is midpoint fromsetpoint, the output is on and off an equal amount of time.

Upper Proportional Band - A band, measured in theunits of the Capacity Control setpoint, above theupper dead band, where proportional load control isused. If the actual reading rises into this proportionalband, the load output will be pulsed as explainedabove in the description about proportional band.When in this band the Master compressor sequencecontroller will begin the process of starting thecompressor.

Lower Proportional Band - A band, measured in theunits of the Capacity Control setpoint, below the lowerdead band, where proportional unload control is used.If the actual reading falls into this proportional band,the unload output will be pulsed as explained above inthe description about proportional band.

Upper Dead Band - A band, measured in the units ofthe Capacity Control setpoint, above the setpoint atwhich the compressor will neither load nor unload.

Lower Dead Band - A band, measured in the units ofthe Capacity Control setpoint, below the setpoint atwhich the compressor will neither load nor unload.

The Cycle Time setpoint determines the amount of timethe output is on and off, when in the proportional band. Atthe completion of the cycle time the actual reading andnecessary response is re-evaluated. If a 4 second periodis selected, then the following will result:

Proportional DistanceActual Reading is

From Setpoint

OutputPulsed On(seconds)

Output Off(seconds)

0 0 41/4 1 31/2 2 23/4 3 11 4 0

Upper Cycle Time - This setpoint determines theamount of time in seconds that the load output is onand off, when in the upper proportional band. Refer tothe above description about cycle time.

Lower Cycle Time - This setpoint determines theamount of time in seconds that the unload output ison and off, when in the lower proportional band. Referto the above description about cycle time.


The following setpoints are required for each compressorto be sequenced:

Minimum Capacity when Running - This is the slidevalve position a compressor will continuously load to,when started. The compressor will not unload belowthis setpoint during normal system operation. The lastcompressor that was signaled to start will be the firstcompressor to unload to it’s Minimum Capacity whenRunning setpoint. Once the compressor has unloadedto this capacity position, a previous compressor isthen allowed to unload. When the Slide Valve isabove this setpoint + 1, the Slave sequence controllerenergizes the Slide Valve > Minimum Capacity output.

Minimum Capacity to Stop Next Compressor - Ifthis compressor unloads to or below this setpoint andthe next compressor stop delay has timed out, thenthe Slave Start output signal is de-energized to tell thenext compressor to stop. This compressor unloads tothis capacity position after the next compressor isrunning at or below it’s Minimum Capacity whenRunning setpoint.

Next Compressor Start Delay - The minimum timein minutes that the actual capacity must be at orabove the starting capacity control setting before theMaster sequence controller will start it’s compressor.Also, the minimum time in minutes that a compressormust be at or above 98% slide valve position beforethe Slave Start output signal is energized to start thenext compressor and the Capacity Up output signal isenergized to tell the next compressor to load. Thistimer helps prevent cycling compressors on and offdue to short sudden changes in load within thesystem. If the Master’s current reading falls below it’sCapacity Control setpoint plus the Upper Dead Bandsetpoint, the Master’s start time delay will be reset tostart counting again. If a running compressor’s slidevalve position falls below 98%, the start time delay forstarting the next compressor will be reset to startcounting again.

Next Compressor Stop Delay - The minimum time inminutes that a running compressor must be at orbelow the Minimum Capacity to Stop NextCompressor slide valve position before the SlaveStart output is de-energized to signal the nextcompressor to stop. This is also the minimum time inminutes that the actual capacity must be at or belowthe Capacity Control setpoint minus the Lower DeadBand setpoint before the Master that has alreadyunloaded the compressor to at or below its MinimumCapacity when Running setpoint + 1, will furtherunload the compressor to below its Minimum SlideValve Position to Start setpoint, and then stop.

This timer helps prevent cycling compressors on andoff due to short sudden changes in load within thesystem. If a running compressor’s Slide Valve positionrises above the Minimum Capacity to Stop NextCompressor setpoint, the stop timer for stopping thenext compressor will be reset to start counting again.And if the actual capacity rises above the Master’sstopping Capacity Control setting, the Master’s stoptime delay counter will be reset to start counting again


[Compressor Sequencing Activate] - Selects to usecompressor sequencing to control this compressor.The delay timers that are present when sequencecontrol is activated won’t change by simply changingthe setpoint. Sequence control must be de-activatedand then activated again.

[Compressor Sequencing De-Activate] - Selects tonot use compressor sequencing to control thiscompressor. The Digital Board 2 outputs 1 through 3and 8, are turned off.

A toggle key is provided for control type:

[Control Type Master] - Only one panel should beselected as the Master. The Master compressorsequence controller attempts to maintain it’s capacitycontrol setpoint by being the first compressor to startand then loads and unloads in response to it’sCapacity Control setpoints and furthermore will signalthe next panel (a Slave) to do likewise.

[Control Type Slave] - The Slave compressorsequence controller is signaled from a previous panelto load or unload, and then uses it’s capacity controlsetpoints to determine when to pulse the panel’s localSlide Valve load and Slide Valve unload outputs.

Compressor Sequence Overview (Mode 2)

The above settings are used to sequence thecompressors that have been setup for compressorsequence control mode 2. The panels selected forcompressor sequence control mode 2 must be connectedvia the proper hardware connection. Only a compressorthat is in both remote compressor mode and remote SlideValve mode and not in shutdown, will be started, stopped,loaded or unloaded using this sequence control.

The refrigeration load refers to the demand for loading ofcompressors to reduce the rise in capacity that hasresulted from an increased need for refrigeration in theplant. When the load rises this means the capacity hasrisen. When the load falls this means the capacity hasfallen. Compressors need to load if the Master sequencecontroller’s capacity reading is above it’s Upper DeadBand setpoint plus the Capacity Control setpoint andcompressors need to unload if the Master sequencecontroller’s capacity reading is below it’s Capacity Controlsetpoint minus the Lower Dead Band setpoint. Duringcompressor sequencing, if the Capacity Up output(request to load the next compressor) is energized, thenthe Capacity Down output (request to unload the nextcompressor) is not energized; and likewise, if the CapacityDown output is energized, then the Capacity Up output isnot energized.

If one of these compressors has been told to run butremains off due to remaining Recycle Delay time or otherconditions preventing the compressor from running, thenno sequencing will happen until the compressor is runningor shutdown.

If one of these compressors is not in remote compressormode or is not in remote Slide Valve mode or is in


shutdown, that compressor is not available to besequenced. However, it will signal its Capacity Controlrequirements to the next compressor.

Because the next compressor is forced to load to theMinimum Capacity when Running setpoint, excesscapacity could occur causing the previous compressor toadjust by unloading a little. If the load continues to risethen the previous compressor that unloaded to below 98%will load again to at or above 98% prior to signaling thenext compressor to load.

The following is an example of sequencing compressors:

On System Start-up - The Master compressor willstart if the capacity is greater than or equal to theUpper Dead Band plus the Capacity Control setpointfor the Next Compressor Start Delay time period. Ifthe Master is not available to be sequenced, then theMaster’s Start Slave output and Capacity Up outputare energized. If the Slave with the Start Slave inputand the Capacity Up input energized is not availableto be sequenced, then the Slave’s Start Slave outputand Capacity Up output are energized.

On an initial start-up of a compressor, the compressorstarted will load to the Minimum Capacity whenRunning setpoint and remain at or above this setpointuntil stopping. A Slave sequence controller energizesthe Slide Valve > Minimum Capacity output when theSlide Valve is above the Minimum Capacity whenRunning setpoint + 1.

Load Rises - If the Actual reading continues to begreater than or equal to the Upper Dead Band plusthe Capacity Control setpoint at the Master sequencecontroller, then the first available compressor in theorder the panels are wired, starting with the Mastersequence control panel is selected to load to 100%,followed by the next compressor.

If the running compressor loads to at or above 98%Slide Valve position for the Next Compressor StartDelay time period, then the Start Slave output andCapacity Up output are energized.

Load Falls - If the Actual reading falls to or below theCapacity Control setpoint minus the Lower DeadBand setpoint at the Master sequence controller, thenthe last compressor that is running will be selected forunloading. If the Start Slave output is energized(indicating another compressor has been told to run)the Capacity Down output is energized. If the StartSlave output is not energized and the Capacity Downinput is energized then this compressor is unloaded toit’s Minimum Capacity when Running setpoint. If theStart Slave output is energized and the Slide Valve >Minimum Capacity input is not energized (indicatingthe next compressor has been unloaded to at orbelow the Minimum Capacity when Running setpoint)then this compressor is unloaded to or below itsMinimum Capacity to Stop Next Compressor setpoint.When the Next Compressor Stop Delay has timedout, then the Start Slave and Capacity Down outputsare de-energized.

A running compressor that is signaled to stop willunload to or below it’s Highest Slide Valve Position toallow starting the compressor setpoint and then willstop. The Master sequence controller is the lastcompressor to unload. The Master will unload thecompressor to the Minimum Capacity when Runningsetpoint and if the Master’s stop delay has timed out,the Master will unload the compressor to it’s HighestSlide Valve Position to allow starting the compressorsetpoint before stopping this compressor.

Compressor Interlock

This screen is shown if the [Compressor Interlock]option of Compressor Sequencing was selected inPanel Setup. For quick access to this screen there is a[Compressor Interlock Setpoints] screen key on theOperating Status -2 screen. Compressor interlocking isused to interlock the running of one high stagecompressor with one booster compressor. This optionshould be selected and setup on the booster compressorand requires serial communication between the twocompressors using the Com-1 port. Reference drawingnos. 640A0042 and 640A0050. These compressors aresequenced only if the compressor is in the remote startmode of operation and in remote Slide Valve mode andavailable to run i.e. not in shutdown (cutout) or RecycleDelay.

When Compressor Interlock is activated, the programchecks the running status of the two compressors. Whenthe booster is started, the program checks if the high

stage machine is running. If it is not running, it is told tostart. After the high stage is confirmed to be running, thebooster will start. If the booster is running and the highstage compressor has a shutdown, the booster shutsdown with a Compressor Interlock Failure. If the booster isstopped, both machines will stop.

This screen has the following setpoint:

High Stage ID – The Identification number of the highstage compressor.


[Activate] - Selects the compressor control to becurrently active.

[De-Activate] - Selects the compressor control to becurrently not active.


Input Module Selection

This screen is shown if the [Input Module CapacityControl Selection] was enabled in Panel Setup. Thesemodes will only be selected when Capacity Control sourceis remote. The following control logic is concluded aboutinput module 19 and 20:

When input module 19 is de-energized:The enabled Capacity Control that is listed first on theCapacity Control screen will be the Capacity Controlthat will be made active using the following controllogic:

• When input module 20 is not energized:Mode 1 is the active Capacity Control.

• When input module 20 is energized:Mode 2 is the active Capacity Control.

When input module 19 is energized: If a secondCapacity Control has been enabled, the enabled

Capacity Control listed secondly on the CapacityControl screen will be the Capacity Control that willbe made active using the following control logic:

• When input module 20 is not energized:Mode 1 is the active Capacity Control.

• When input module 20 is energized:Mode 2 is the active Capacity Control.

When this feature is enabled, these inputs force whichCapacity Control is active, even if a different CapacityControl mode is selected somewhere else. Only if theCapacity Control mode was forced by these inputs willRemote-I/O be displayed for the Capacity Control sourceon the Operating Status screen. The [Make Active] keywill not be available on a Capacity Control setpoint screenwhen this feature has been enabled.


Auxiliary Setup

This screen is shown if a type of [Auxiliary 1 and 2]control was selected in Panel Setup. The auxiliary digitalinput modules can be selected as an alarm or a shutdownwhen the auxiliary input is de-energized. The auxiliary canbe checked either Always Active or When running.

• Always Active means that at anytime the inputmodule is de-energized, the selected type ofauxiliary will occur if the module remains de-energized for the length of the delay period.

• When running means that only when thecompressor is running and the input module isde-energized, the selected type of auxiliary willoccur if the module remains de-energized for thelength of the delay period.

The following screen keys are used to setup how theauxiliary will function:

[Change Setpoints] - Changes the number ofseconds to delay prior to producing either an alarm ora shutdown.

A toggle key is provided that changes between thefollowing types of auxiliary:

[Auxiliary 1 Type Alarm] - If the Auxiliary 1 ispresently a shutdown type of auxiliary this screen keyis shown so that the operator can change the auxiliaryto an alarm type.

[Auxiliary 1 Type Shutdown] - If the Auxiliary 1 ispresently an alarm type of auxiliary, this screen key isshown so that the operator can change the auxiliaryto a shutdown type.

A toggle key is provided that changes when the auxiliary ischecked:

[Auxiliary 1 Checked Always] - If the Auxiliary 1input module is presently checked When running, thisscreen key is shown so that the operator can changewhen it is checked to Always Active.

[Auxiliary 1 Checked Running] - If the Auxiliary 1input module is presently checked Always Active, thisscreen key is shown so that the operator can changewhen it is checked to When running.

Note: If an Auxiliary 2 option was also selected, thenthe screen keys described above but labeled Auxiliary2 are relevant to setting up the Auxiliary 2 inputmodule.


Pull Down

This screen is shown if the Pull Down option was selectedin Panel Setup. Pull Down is only valid when in SuctionPressure Capacity Control. With this option enabled, theSuction Pressure can be slowly lowered in steps from theStarting Suction Pressure setpoint to the Suction PressureCapacity Control setpoint. Slowly walking the pressuredown prevents rapid drops in system pressure that causesviolent boiling of refrigerant in the system. When theSuction Pull Down feature is activated and the compressoris started, the Capacity Control setpoint is changed to thecurrent Suction Pressure. After the Amount of Timesetpoint has timed out the Capacity Control setpoint ischanged again. The Capacity Control setpoint is reducedby the amount of the pressure band. The system stepsdown to this setpoint and stays there until the time-outperiod has again elapsed. Then the Capacity Controlsetpoint is reduced again. The Capacity Control setpointchanges regardless of whether the system is following it ornot. The Suction Pressure Pull Down feature is re-activated every time the machine is started unless it is de-activated.


Suction Pressure Reduction Step Pressure Band -This is the amount of Suction Pressure that will beused to step down the system. This value issubtracted from the starting Suction Pressure toprovide a Capacity Control setpoint. The CapacityControl setpoint continues to be calculated bysubtracting the pressure band from the previouslycalculated Capacity Control setpoint until the SuctionPressure reading reaches the operator enteredCapacity Control setpoint.

Suction pressure Reduction Step Amount of Time– This is the time in minutes the Suction Pressure ismaintained at each step during Suction Pressure pulldown.

Pull Down using Slide Valve Position

• Slide Valve Position - The percentage oftravel that the Slide Valve is permitted toload upon Compressor starting, andthereafter determined by the Amount of Timesetpoint. For example, if this setpoint is 5%,and the Amount of Time setpoint is 1 Minute,then the Slide Valve will be permitted to load5% of its stroke every minute, until such timeas the compressor has reached capacity. Itwould take 20 minutes for the Slide Valve tofully load to 100% at this rate. When theSlide Valve is not moving, the followingmessage will be displayed on the OperatingStatus screen Stop Load - Slide ValvePulldown: xx% where xx is the Slide ValvePosition percentage. Once capacity hasbeen achieved, this function is ignored, untilsuch time as the compressor is restarted.

• Amount of Time - The amount of timebetween when the Slide Valve is permitted tomove. See Slide Valve Position description.

Note: It is recommended to use Suction Pull Down whenusing Suction Pressure Mode 1 or 2, for best results, useSlide Valve Pull Down.


Vibration Monitoring

This screen shows the setpoints for Vibration Monitoring (ifapplicable). Pressing the [More…] key will show thesecond screen of parameters. To change setpoints, pressthe [Change Setpoints] key, and scroll to the setpoint youwish to change.

For more information, refer to Frick® document E70-020TB (PhD Vibration Monitoring System).


Security Setup

Security can be setup to allow different operators differentaccess rights to setpoints. If access is presently deniedwhen an operator selects to [Change Setpoints] then amessage box will appear prompting the operator to enter apassword. If an operator has not changed any setpointwithin the last 15 minutes, the access level will change tono access.

Three levels of access rights to changing setpoints isprovided:

1. Full Access - allows an operator to change allsetpoints and passwords. If a password isrequired, a level 1 password provides full access.

2. Moderate Access - allows an operator to changesetpoints, but prevents changing safety setpointsand passwords.

3. No Access - prevents an operator from changingany setpoint or password.

To have full access requiring a password, enter apassword other than zero for the full access entry. Tohave moderate access, enter a different password for themoderate access entry than the full access entry. If anoperator does not know an entered password then theyare prevented from changing any setpoints. To disablesecurity, enter zero for both full and moderate accessentries. Disabling security allows any operator to changeall setpoints without entering a password.

The following information about the current securityaccess is shown:

Current Security Privilege Level:

1. No Access2. Moderate Access3. Full Access

Change Setpoints from Keypad:

1. Enabled2. Disabled

If a password exists, then selecting a screen key willcause a password entry box to appear. To change apassword the operator must enter their password andaccept it (OK) which will cause another password entrybox to appear. It prompts the operator to enter thepassword for this access level. Accepting it will causeanother password entry box to appear. It prompts theoperator to reenter the password to verify it. Properlyreentering the password will cause a message box toappear that says Pass Number Changed. Improperlyreentering the password will cause a message box toappear stating Bad Verify Pass Number Not Changed.

The following screen keys are used to setup security.

[Change Full Access] - Select this key to change thefull access password. The operator can also enter thecurrent password to acquire full access privilegewithout changing the password.

[Change Moderate Access] - Select this key tochange the moderate access password. The operatorcan also enter the current password to acquiremoderate access privilege without changing thepassword.

[No Access] - Select this key to change the currentaccess privilege to no access. This cancels securityaccess to the system. A password must be re-enteredto gain security access after pressing this key.


CALIBRATION AND SETUPCalibrations should be performed anytime one or moreanalog channels appear to be inaccurate, or whenever anew analog device or analog board is replaced or installedin the system. All analog calibrations should be checkedon a regular basis to ensure proper operation of thesystem. This should be considered as part of the normalmaintenance schedule, and will vary as to the frequency of

the individual customers requirements. A good startingpoint would be to check all calibrations once per year. Thistime frame can then be modified as conditions warrant.

Analog Output Setup

The screens on this page are used to assign physicalanalog input channels to an analog output.

Note: If re-transmitting any analog channels, ensure thatthey are properly configured before doing analog setup.


Analog Output Setup

Use this screen only if the analog output signal needscalibration and it can not be calibrated at the device.

The Quantum’s analog outputs have a range ofapproximately 0 to 25 mA, but most devices that are beingcontrolled by the Quantum require a signal that variesbetween 4 and 20 mA. To restrict the analog outputs tothe proper values, each of the outputs must be calibratedbefore they can be used. Every output channel has a TopEnd and a Bottom End setpoint that are used forcalibration. Both values can be set from 0% to 100%. Theoutput channel’s maximum value is represented by 100%and its minimum value is represented by 0%. To calibratethe channel the Top End percentage is decreased until themaximum output for the channel is limited to 20mA. Also,the Bottom End percentage is increased until the minimumoutput for the channel is 4mA.

Below is a step by step procedure for calibrating oneanalog output.

8. Press the [Select Rate of Change] key once todecrease the Rate of Change to 1.00.

9. Use the [Increase Top End] key and the[Decrease Top End] key to again find the valueclosest to 20 mA.

10. Repeat steps 8 and 9 for Rate of Change valuesof 0.1 and 0.01 to bring the output value as closeas possible to 20mA.

11. Press the [Previous Screen] key.

12. Press the [Set Output to Bottom End] key andthe output value should drop to 0%.

13. Press the [Calibrate Bottom End] key.

14. Check that the Rate of Change value is 10.00. Ifit is not, press the [Select Rate of Change] keyuntil it is displayed as 10.00.

15. If the channel’s output is greater than 4 mA,press the [Decrease Bottom End] key. If thechannel’s output is less than 4 mA, press the[Increase Bottom End] key. Use these keys tofind the output value closest to 4 mA.

16. Press the [Select Rate of Change] key once todecrease the Rate of Change to 1.00.

17. Use the [Increase Bottom End] key and the[Decrease Bottom End] key to again find thevalue closest to 4 mA.

18. Repeat steps 16 and 17 for Rate of Changevalues of 0.1 and 0.01 to bring the output valueas close as possible to 4mA.

19. Press the [Previous Screen] key.

20. Press the [Standard Output Control] key toallow the output to return to standard control.

Each of the schedules may be customnamed. This screen is based upon the MaintenanceSchedule that is provided in the IOM manual for thespecific compressor package.

The usage of this screen is that the user can define up tofifteen different areas of compressor operation that theywould like to schedule routine maintenance for. As anexample, the above screen shows a row labeled as OilAnalysis. The next column (Service Every) on the samerow has a value of 10000 Hrs. The last column (NextScheduled At) of this row has a value of 1000 Hrs. Whenthe compressor is running, this time value is beingclocked. After 1000 hours of compressor run time, analarm will be generated alerting the user with an alarmmessage which will read Maintenance -- Oil Analysis. Thisis to notify the operator that it is time to have the Oilchecked. At this point, the operator should notify theproper maintenance personnel that the appropriatemaintenance be performed.

Once the alarm has occurred, the values for the row thatthe alarm occurred in will be automatically updated, withnew values as predetermined by an internal programmedmaintenance schedule, based upon the type ofcompressor. The values for the Next Scheduled at columnare based upon the Compressor Run Time hours. The left most column is the user defined MaintenanceRequired column. This is where custom names may be

OPERATION OVERVIEWInitial Setup Procedure:

1. Factory Setup should be performed by a FactoryRepresentative or Distributor to setup the customerspecific control features which should not need to bechanged by operators.

2. Panel Setup is performed to setup panel features andoptions, which can later be changed by an operator.Features such as the panel time, and screen color arechanged here. Options such as Condenser Controlare enabled here. The operator can avoid viewing andentering settings of unused controls by keepingunused options disabled.

3. Calibrate the control devices. 4. From Control Setup, enter and setup the control

settings. 5. From Security Setup, establish the desired access

rights of the operators. 6. The Operating Status screens now provide quick

access to the most important information and controlsof the compressor unit and the subsystems.

Compressor Start-Up Procedure:

• Starting is shown for the Compressor status on theOperating Status screen.

• All the safeties are checked. If any shutdowncondition is present the corresponding alarmmessage is shown and the compressor is preventedfrom starting.

• The oil lubrication is checked. A Prelube pump needsa 5 lb. oil pressure differential to allow the compressorto start. A full time pump needs a 20 lb. Oil Pressuredifferential to allow the compressor to start. Othercompressor manufacture’s Oil Pumps needs a 30 lb.Oil Pressure differential to allow the compressor tostart. If one of these conditions is not present analarm message is issued and the compressor isprevented from starting.

• The Slide Valve position is checked to see if it is lessthan or equal to the Highest Slide Valve Position toallow starting the compressor setpoint. If the SlideValve position is higher than this, the compressor isprevented from starting.

• If none of the above conditions has prevented thecompressor from starting, a timer delay is started thatrequires the starting conditions to remain satisfied fora period of five seconds for all compressor modeltypes except [Other Compressor Manuf.]. The Othercompressor model type uses a 20 seconds delay.After the time delay the compressor and the RecycleDelay timer are started.

• If within 30 seconds, the Compressor Start Auxiliaryinput has not been energized, or Motor Current is notdetected, then an alarm message is issued and thecompressor is shut down.

• When the compressor begins running, the OilPressure values are in a state of change. For a periodof 10 seconds after the compressor status switches toRunning, the low Oil Pressure alarm and shutdownsafeties are ignored.

Compressor Stopping Procedure:

During the compressor stopping, the Slide Valve unloadsolenoid remains energized until the Slide Valve isunloaded to or below the Highest slide valve position toallow starting the compressor setpoint. If the Slide Valvedoes not unload below this setpoint within 5 minutes, thealarm message Compressor Unable to Unload - Alarm isissued.

Setup For Automatic Control:

In order to operate a compressor at peak efficiency, underfull load and part load conditions complex controlsequences must be used. In order to obtain theefficiencies, Automatic Control is almost mandatory.Automatic control of the Slide Stop and Slide Valveincreases the compressor efficiency over a wide operatingrange. The following steps (which are relevant) should betaken to control in Automatic:

• The compressor should be in automatic(automatic cycling) so the compressor will startand stop according to the Autocycle setpoints.

• The Oil Pump should be in auto because it’soperation coincides with that of the compressor.

• The Slide Valve and the Slide Stop should be inAutomatic so they are controlled by setpoints andinternal control logic.

Note: If there is a shutdown in response to a safetysetting, a compressor in Automatic mode is placedinto Manual mode requiring operator intervention.

Remote Control Of The Compressor:

The following digital outputs and inputs (on Digital Board2) have been provided that can be used to control thecompressor from another controller such as a PLC:

• (Module 1) - Ready to Run - This output isenergized while the compressor is not shutdownand the Recycle Delay has timed out.

• (Module 2) - Remote Enabled - This output isenergized while the compressor is in RemoteStart mode.

• (Module 3) - Remote Start / Run / Stop - If thecompressor is in Remote Start mode with noRecycle Delay time and this input is energized,the compressor is started. If this input isenergized and the compressor is started, it willcontinue to run. If this input is de-energized, thecompressor is stopped.

• (Module 4) - Remote Load or Remote C.C step1 for step units

• Remote Load - If the Slide Valve is inRemote Mode and this input is energized,the Slide Valve load solenoid will beenergized provided there are no safetyoverrides preventing loading.

• Remote C.C step 1 for step units - If theCapacity Mode is in Remote this input isused to step on and off capacity according tothe Remote Capacity Control chart.


• (Module 6) - Remote Unload or Remote C.Cstep 2 for step units

• Remote Unload - If the Slide Valve is inremote and this input is energized, the SlideValve unload solenoid will be energized.

• Remote C.C step 2 for step units - If theCapacity Mode is in Remote this input isused to step on and off capacity according tothe Remote Capacity Control chart.

• Recycle Delay (If compressor is off) - Thisoutput is energized while the remaining timein minutes for Recycle Delay is greater thanzero (0). Recycle delay time is the time thatmust elapse prior to allowing the compressorto restart. This timer times out while thecompressor is running or stopped since theRecycle Delay is a start-to-start protection.The Recycle Delay time is intended toprevent damage to the motor fromsuccessive restarts. For further setup seethe Motor Control Setpoints screen

• Sequence Input (If compressor is on) –Reports the status of Stop Load or ForceUnload (See Slide Valve and Slide StopStatus box for further details).

The Hot Gas Bypass/SV Setpoint option can be used.This option, which is enabled in Panel Setup, is notavailable for all compressor models (ReferenceCompressor Model Differences). Three digital outputs areprovided that signal when the Slide Valve has reachedpreset positions. For further setup, see the Slide ValveSetpoints screen.

The Remote Control Setpoint option can be used. Thisoption, which is enabled in Panel Setup, is not available

for all compressor models (Reference Compressor ModelDifferences). This uses the Remote Control Setpointanalog input and the Remote Control Setpoint analogoutput for Capacity Control of compressors. For furthersetup see the Calibrate Remote Control Setpoint screenand the [Remote Setpoint] command key from the SlideValve Mode screen command keys on the OperatingStatus screen.

The Remote Slide Valve Position option can be used. Thisoption which is enabled in Panel Setup is not available forall compressor models (Reference Compressor ModelDifferences). This uses a (4-20 ma) input signal to theRemote Slide Valve Position analog input (Channel #13on Analog Board #1) to control the Slide Valve. For furthersetup see the Calibrate Slide Valve Position screen andthe [Remote Slide Valve] command key from the SlideValve Mode screen command keys on the OperatingStatus screen.

The Slide Valve Position \ Capacity analog output can beused to determine the present Slide Valve position % orCapacity % dependent on the compressor model(Reference Compressor Model Differences). A (4-20 ma)output signal to the Slide Valve Position \ Capacity analogoutput (Channel #3 on Analog Board #1) corresponds tothe present (%) value displayed on the Operating Statusscreen.

ASCII communication to the Com-2 port can be used(reference S90-010 CS Communications Setup manual).A compressor should be in both Remote CompressorMode and Remote Slide Valve or Capacity Mode forRemote Control.

Note 1: If the compressor is in Remote mode andcommunication through the communication port hasnot occurred for 5 minutes, then the compressor isplaced into Automatic mode and the Slide Valve isplaced into Auto mode.

Note 2: If there is a shutdown in response to a safetysetting, a compressor in Remote mode is placed intoManual mode requiring operator intervention.
