TYPICAL SYSTEM CONFIGURATION

QUANTUM LX CONTROL PANEL

The Quantum LX control panel contains all of the nec-essary control hardware and software within one selfcontained enclosure, and is mounted to the compressorpackage. The front of this control enclosure contains agraphic display and keypad to allow the operator to ac-cess essential information and to make necessary adjust-ments to setpoints, calibrations and features.

Operator access to this system is through various screens.A screen is the physical representation of data on the dis-play. Each screen has a title area and is descriptive ofthe screen. The current date and time is shown in this

title area. The day of the week, Sunday (Sun.) throughSaturday (Sat.) is displayed. The month of the year fromJanuary (Jan.) to December (Dec.) is displayed. The day ofthe month from 1 to 31 and the year from 0001 to 9999is displayed. The time displayed is the current time in 24hours (military) format. The hours, minutes and secondsare displayed.

Some screens are for informational purposes only, andcannot be modified. These screens typically show ana-log values such as temperatures, pressures and humidity,which are strictly functions of an associated sensor, andas such, cannot be modified. Other screens show setpointvalues which can be changed, in order to modify the units

Frick Compressor packages may be used individually, orin groups. This section will describe some of the variousconfigurations that may be used with regard to electricalcontrol.

Each individual Compressor unit is controlled by a com-puter based machine control system, known as the Quan-tum LX control panel. This controller continuously mon-itors the conditions and operation of the compressor unitand the various subsystems. It also directs the operationof components. It is fully self-contained.

The Quantum LX control panel user interface is used to

display graphic screens, which represent various aspectsof compressor operation. By pressing a key on the key-pad, the labeled or described function is recognized by thecontrol processor, and appropriate action is taken.

Although the primary means of operator interaction tothe compressor package is via the built-in QuantumLX control panel, there are two additional methods thatemulate the graphic control screens that may be usedremotely for compressor control. The following informa-tion is presented to help the operator interact with thesegraphic screens.

operating characteristics. For easier viewing, related in-formation is separated into boxes. Sometimes selectionsare hidden when that the feature is unavailable.

OPERATOR ACCESS

Operator access to this system is through various screens.A screen is the physical representation of data on the dis-play. Each screen has a title area. The title is descriptiveof the screen. The current date and time is shown in thistitle area. The day of the week, Sunday (Sun.) through

Saturday (Sat.) is displayed. The month of the year fromJanuary (Jan.) to December (Dec.) is displayed. The day ofthe month from 1 to 31 and the year from 0001 to 9999is displayed. The time displayed is the current time in 24hours (military) format. The hours, minutes and secondsare displayed.

TO CHANGE SETPOINTS

Some screens are for informational purposes only, andcannot be modified. These screens typically show ana-log values such as temperature and humidity, which arestrictly functions of an associated sensor, and as such,cannot be modified. Other screens show setpoint values

which can be changed, in order modify the units operatingcharacteristics. For easier viewing, related information isseparated into boxes. Sometimes selections are hiddenwhen that the feature is unavailable.

The setpoints define the operation and limits of each unit.These setpoints can be change by operators in the field.These setpoints are stored on the Compact Flash card.

NOTE:Setpoints are not lost after power is interrupted.However, we suggest that a list of Setpoints be recordedand stored safely to facilitate reentry, in case there is aneed to return to the original settings.

1. The data entry fields are identified by a black boxwith a white interior. The data is shown in black text.When on a screen that has adjustable setpoints, tabto the setpoint box that you wish to modify (or se-lect it on a web browser).

2. The current value of that setpoint is shown. Usethe keypad to enter the new value. Typing a new

value will completely erase the old value.3. Press the keypad [ENTER] or[Tab]key to inputthe new data in the data entry field and to move to

VOLUME:

Manual Automatic

RUN HOURS The total amount of time in hours thatthe compressor motor has run.

WARNING/SHUTDOWNS STATUS BOX- The Warn-ing/Shutdowns Status is displayed below the Capac-ity/Volume status box. This status box is blank withno message if there are no warnings or shutdownspresent.

If a Warning or Shutdown occurs, a flashing mes-sage will be shown, identifying the type of warning orshutdown. As an example, if the Oil Temperature hasbeen less than or equal to the Low Oil TemperatureWarning setpoint for its time delay setting, then aLow Oil Temperature Warning will be shown. If thewarning is not cleared by the operator, and the Oil

Temperature continues to drop to a point that is lessthan or equal to the Low Oil Temperature Shutdownsetpoint for its time delay setting, then a Low OilTemperature Shutdown is issued, and the compres-sor, if running, will stop. The definitions for the twotypes of messages are as follows:

WARNING- A specific warning message flasheswhen a warning is present. A warning is a con-dition that requires operator acknowledgementbut allows the compressor to continue to run if itis already running.

A Warning message indicates that a warningsetpoint has been reached, or exceeded.

SHUTDOWN - This specific shutdown messageflashes when a shutdown is present. A shutdownis a condition that requires an operator to ac-knowledge, and causes the compressor to shutdown.

A Shutdown message indicates that a shut-down setpoint has been reached, or ex-ceeded.

When a Shutdown occurs, the display back-light will flash on and off to alert an operator

of the shutdown. This visual alarm will helpget the attention of the operator in a noisyengine room environment where audiblealarms may not be heard. Pressing any keyon the keypad will clear the flashing back-light.

OPERATING VALUES - Sequencing

ACCESSING:

DESCRIPTION:This screen will be available if Sequencing is enabled in Compressor configuration. This is strictly a statusscreen; no values can be changed from here.

Operating Values Se uencin

The following is a description of the Sequencing strategy:

Start/Stop

System Setup: Control Input Suction Pressure Control Direction Forward High Stage Link Disabled

Start Procedure

Before starting a compressor, the master mustdetermine that all running compressors are load-ed and that the Suction Pressure has risen to apoint where an additional compressor is needed.

First, the master checks that either no compres-sors are running or all the running compressors

average 90% capacity. If a running compressor isat less than 90% capacity but is in a Load Inhibitor Force Unload condition, for the purposes ofthis calculation it is assumed to be at 90% ca-pacity.

If all the running compressors are loaded themaster next begins comparing its Suction Pres-sure to the Autocycle Start setpoint. When theSuction Pressure rises above the Start setpoint,the start timer is initiated. If the start timerreaches the Autocycle Start Delay setpoint timeand the Suction Pressure has remained abovethe Start setpoint for the entire time, the master

attempts to start an additional compressor. If theAutocycle Start Delay setpoint is 0 minutes, themaster still waits 15 seconds before starting acompressor.

To determine which compressor to start, themaster first sorts all the compressors in the sys-tem based on their start number, low to high.If two compressors have the same start num-ber, the first one on the list remains ahead ofthe second. Next, the master starts at the topof the list and works down through list until itfinds a compressor that is available to run. To bedeemed available, a compressor must have goodsequencing communications and its CompressorMode and Capacity Mode must be set as RemoteSequencing. In addition the compressor mustbe off, and it cannot be in a Start Inhibit condi-

tion except for the Start Inhibit Slide Value TooHigh condition. The compressor with the loweststart number that also meets these conditions isthen sent a start command. If no compressorsare currently available to start, the master willcontinue checking until one becomes availableor until the Suction Pressure drops below theStart setpoint.

After a compressor has been sent a start com-mand, the master waits for that compressor toreach a Running state. If 3 minutes passes andthe compressor has not yet begun to run, themaster sends it a stop command. This com-


14/112


090.022-O (JUN 11)Page 14

pressor is then flagged as Unable to Start for 1hour. After that time the master may again try torestart the compressor if additional capacity isneeded. After a compressor begins running, orafter one fails to start and is sent a stop com-mand, the master can begin the process of start-ing another compressor.

Stop Procedure

If the Suction Pressure drops to a point whereone of the running compressors is no longerneeded, the master will stop the last compressorin the sequence list.

When the Suction Pressure drops below the Au-tocycle Stop setpoint, the stop timer is initiated.If the stop timer reaches the Autocycle Stop De-lay setpoint time and the Suction Pressure hasremained below the Stop setpoint for the en-tire time, the master attempts to stop one of therunning compressors. If the Autocycle Stop De-lay setpoint is 0 minutes, the master still waits 15seconds before stopping a compressor.

To select the compressor to stop, the master alsosorts all the compressors in the system accord-ing to their start number. Then the master startsat the bottom of the list and works up, lookingfor a running compressor that can be stopped.To be selected a compressor must have goodsequencing communications and its Compres-sor Mode and Capacity Mode must be set as Re-mote Sequencing. In addition, the compressorsrun time must be greater than the compressorsMinimum Run Time setpoint. If the Minimum

Run Time setpoint is 0 minutes, a compressorcan also be stopped if it is still in Starting mode.The compressor with the highest start numberthat meets these conditions is sent a stop com-mand. If no compressors are currently availableto stop, the master will continue checking untilone becomes available or until the Suction Pres-sure rises above the Stop setpoint.

After a compressor has been sent a stop com-mand, the master waits for that compressor togo to off. If 3 minutes passes and the compressorhas not yet turned off, the master then flags thiscompressor as Unable to Stop for 1 hour. After

that time the master may again try to stop thecompressor. After a compressor goes to off orafter one fails to stop within 3 minutes, the mas-ter can begin the process of stopping anothercompressor.

Load/Unload

System Setup:

Control Input Suction Pressure Control Direction Forward High Stage Link Disabled

Load Procedure

If the master compressors Suction Pressure isabove the Capacity Control setpoint, the mas-ter calculates the increase in capacity that is re-quired. The calculation is as follows:

Difference = Suction Pressure (Capacity Con-

trol Setpoint + Upper Dead Band)

If the Difference is less than the Upper Propor-tional Band:

Capacity Change = (Difference /Upper Proportional Band) * Upper

Cycle Time

If the Difference is greater than the Upper Pro-portional Band:

Capacity Change = UpperCycle Time

After the capacity increase has been calculated,the master then finds the compressor whose ca-pacity should be changed. To make this deter-mination, the master sorts all the compressorsbased on their start number. Beginning at thecompressor with the lowest start number, themaster finds the first compressor on the list thatis running but is not at its maximum capacity.A compressor is at maximum capacity if it is at100 percent capacity or if it is in a Load Inhibit orForce Unload condition.

If the selected compressor is running the Quan-tum LX software, the capacity increase is

added to the compressors current capacity. Thisnew value is then sent to the compressor as itsCapacity Command, and that compressor will tryto increase its capacity to match the Commandvalue.

If the selected compressor is controlled by aQuantum 1-4 or a Plus panel, the capacityincrease is interpreted as the time period for aload pulse and is sent to the compressor as aload command. The slave compressor will thenturn on its load output for the given number ofseconds.

Unload Procedure

If the master compressors Suction Pressure isbelow the Capacity Control setpoint, the mastercalculates the decrease in capacity that is re-quired. The calculation is as follows:

Difference = (Capacity ControlSetpoint - Upper Dead Band)

Suction Presure

If the Difference is less than the Lower Propor-tional Band:

Capacity Change = (Difference /


15/112


090.022-O (JUN 11)Page 15

Lower Proportional Band) * LowerCycle Time

If the Difference is greater than the Lower Pro-portional Band:

Capacity Change = LowerCycle Time

After the capacity decrease has been calculated,the master then finds the compressor whosecapacity should be changed. To make this de-termination, the master sorts all the compres-sors based on their start number. Beginning atthe compressor with the highest start number,the master finds the last compressor on the listthat is running and whose capacity is above itsMinimum Capacity setpoint. If two compressorsare currently running at or below their MinimumCapacity setpoints, the master will not allow anyadditional compressors to unload. This will al-low the Suction Pressure to continue to drop

and will cause the master to turn off one of theunloaded compressors. If the master sees thatonly one compressor is running in its system, itwill continue to unload the compressor down tothe masters Automatic Capacity Mode MinimumSlide Valve Position setpoint.

If the selected compressor is running the Quan-tum LX software, the capacity decrease is sub-tracted from the compressors current capacity.This new value is then sent to the compressor asits Capacity Command, and that compressor willtry to decrease its capacity to match the Com-mand value.

If the selected compressor is controlled by aQuantum 1-4 or a Plus panel, the capacity de-crease is interpreted as the time-period for anunload pulse and is sent to the compressor asan unload command. The slave compressor willthen turn on its unload output for the given num-ber of seconds.

High Stage/Booster

The High Stage System Link setpoint is providedto tie a system of Booster compressors to a sys-tem of High Stage compressors. For example, ifthe Booster compressors are setup on System #1

and the High Stage Compressors are on System#2, the High Stage System Link setpoint fromSystem #1 would be set as System 2.

When the Booster Systems master wants tostart the first Booster compressor, it first checksthat a Booster compressor is available to run andthen sends a signal to the High Stage Systemsmaster telling it to start a High Stage compres-sor. If all the High Stage compressors are off, theHigh Stage Systems master will start its firstcompressor, regardless of what the High StageControl Input is reading. When the Booster Sys-tems master observes that a High Stage com-

pressor is running, it will allow a Booster com-pressor to start.

After the first High Stage compressor beginsto run, compressors in both systems will cycleon and off as their Control Inputs move up anddown. The only stipulation to the control strat-

egy is that one High Stage compressor must al-ways remain on as long as at least one Boostercompressor is running. If all the Booster com-pressors turn off, the High Stage compressor canthen turn off as well.

Establish Sequencing Communications Using AnEthernet Connection

Perform the following steps on each panel thatwill be part of the sequencing group:

From the Main Menu, select [Session].

SYSTEM STATUS - Maintenance

The usage of this screen is that the user can assign upto seventeen different areas of compressor operationthat they would like to schedule routine maintenance for.

As an example, the above screen shows a row labeledas Oil Analysis. The next column (Service Every) on thesame row has a value of 10000 Hrs. The last column(Next Scheduled At) of this row has a value of 1000 Hrs.When the compressor is running, this time value is be-ing clocked. After 1000 hours of compressor run time, amessage will be generated and placed on the Event Logscreen. This particular message will read Maintenance-- Oil Analysis. This is to notify the operator that it istime to have the Oil checked. At this point, the operatorshould notify the proper maintenance personnel that theappropriate maintenance be performed. The user shouldaccess the Event Screen on a regular basis (perhaps onceper week) to review the information provided there.

Once the message has been entered in the Event Log,the values for the row will be automatically updated, withnew values as predetermined by an internal programmedmaintenance schedule, based upon the type of compres-sor. The values for the Next Scheduled at column arebased upon the Compressor Run Time hours (shown atthe bottom of this screen).

At the bottom of the left-most column is the user de-fined Maintenance Required column. This is where customnames may be entered for the various items that the userwould like to track.

SETPOINTS - Capacity Control

Capacity Control is setup by accessing the Configurationscreen. From that screen, the user can enable or disableany of the four possible modes, as well as select the chan-nel that they wish to control from, and select whether thecontrol will be Forward or Reverse acting.

The Capacity Control screens shown above can display upto four window areas of information:

Capacity Control

Autocycle Mode Safeties Low Suction

NOTE:If the Capacity Control mode is set to controlbased upon suction pressure, then the Low Suctionwindow will appear blank, and the Mode Safetieswindow values will act to protect the compressor forLow Suction situations. If Capacity Control is not con-trolled from Suction Pressure, then the Low Suctionwindow will be populated with values because theMode Safeties window will act to monitor the Ca-pacity Channel, but Low Suction data must also bemonitored simultaneously.

The four widow areas are described as follows:

CAPACITY CONTROL - Capacity Control can be set toact in either Forward or Reverse control. In Forwardcontrol, as the value of the capacity control channelincreases the Quantum LX increases the capacity ofthe compressor. In Reverse control, as the value ofthe capacity control channel decreases the QuantumLX increases the capacity of the compressor. The fol-lowing setpoint boxes are provided:

Setpoint- This setpoint is used to control theloading and unloading of the compressor when

the Capacity Control is in the AUTO (Automatic)or in REM SEQ (Remote Sequencing) modes.

Proportional Band High - A band, measured inthe units of the Capacity Control setpoint, abovethe Dead Band High, where proportional load orunload control is used. If the actual reading risesinto this proportional band the load or unloadoutput will be pulsed as explained below in thedescription about proportional band.

Proportional Band Low - A band, measured inthe units of the Capacity Control setpoint, belowthe Dead Band Low, where proportional load orunload control is used. If the actual reading fallsinto this proportional band the load or unloadoutput will be pulsed as explained below in thedescription about proportional band.

DESCRIPTION OF PROPORTIONAL BANDCONTROL:The Proportional Band setpointdetermines a range of Capacity Control val-ues where pulsed output control is used.Outside of the proportional band the out-

put is continuously energized. The lengthof time the output will be pulsed on is pro-portional to the distance the actual readingis from the Capacity Control setpoint. Thefurther the distance from setpoint, the lon-ger the output is pulsed on and the shorterthe output is off. The closer the distance tosetpoint, the shorter the output is pulsed onand the longer the output is off. If the actualreading is midpoint from setpoint, the out-put is on and off an equal amount of time.

Dead Band High - A band, measured in the unitsof the Capacity Control setpoint, above the set-

point at which the compressor will neither loadnor unload.

Dead Band Low- A band, measured in the unitsof the Capacity Control setpoint, below the set-point at which the compressor will neither loadnor unload.

Cycle Time High- This setpoint determines theamount of time in seconds that the load or un-load output is on and off, when in the upper pro-portional band. Refer to the description belowabout cycle time.

Cycle Time Low- This setpoint determines theamount of time in seconds that the load or un-load output is on and off, when in the lower pro-portional band. Refer to the description belowabout cycle time.

DESCRIPTION OF CYCLE TIME:The Cycle

Time setpoint determines the total amountof time for one on/off cycle, when in theproportional band. At the completion of thecycle time the actual reading and necessaryresponse is re-evaluated. If a four secondperiod is selected, then the following willresult:

ProportionalDistance (Ac-tual Reading isFrom Setpoint)

OutputPulsed On(seconds)

OutputOff

(seconds)

0 0 4

1/4 1 3

1/2 2 2

3/4 3 1

1 4 0

VFD Proportional Band- This is the value abovethe Capacity Control setpoint for forward actionat which the output to the drive will match themaximum output setpoint. Typically, proportionalcontrol alone will not permit running at the con-trol setpoint. If the pressure is within the propor-tional band but not increasing the output will notincrease with proportional control only.

VFD Integration Time - This is the value thatsets the increase of the proportional componentover time.

Example:

Actual Value = 21 PSIGCapacity Control [20 PSIG]Maximum Output [100%]Minimum Output [20%]VFD Proportional Band [4 PSIG]VFD Integration Time [30 sec]

With the actual pressure at 21 PSIG, theproportional component would be 20%. TheProportional Component is calculated as:

[(Actual Value Setpoint) / PB] X (Max-imum output Minimum Output).

[(21 20) / 4] X (100 20) = 20%

When this proportional component is addedto the minimum outpoint setpoint, the to-tal output is 40% proportionally at an actualvalue of 21 PSIG. It is the Integration Timesetpoint which will increase the output overtime without an increase in the actual value.As long as the actual value, (21 PSIG) doesnot change, the Integration Time setpoint,in this case [30 sec], will increase the outputby the proportional component over every30 seconds to drive the actual value back tothe Capacity Control setpoint. If the actual

value remains 21 PSIG, the Integration TimeSetpoint would increase the drive output to100% over 1.5 minutes.

The following status indicator is provided:

Channel - Shows which analog channel isbeing used to control this mode, as set onthe Compressor Configuration screen.

AUTOCYCLE - The following setpoint boxes are pro-vided:

Start- The compressor turns on when the value

of the capacity control input reaches this set-point. This setpoint is used in both AUTO (Au-tomatic) or in REM SEQ (Remote Sequencing)modes.

Start Delay The time in minutes that the valueof the capacity control input must be above (for-ward) or below (reverse) the start setpoint be-fore the compressor will start.

Stop - The compressor is stopped when thevalue of the capacity control input reaches thissetpoint. This setpoint is used in both AUTO(Automatic) or in REM SEQ (Remote Sequenc-ing) modes.

Stop Delay- The time in minutes that the valueof the capacity control input must be below (for-ward) or above (reverse) the stop setpoint be-fore the compressor will stop.

MODE SAFETIES:

Forward Acting As the Capacity Control val-ue drops below the capacity control setpoint,these setpoints will protect the compressor bydecreasing the capacity, or if necessary shuttingdown the compressor.


32/112


090.022-O (JUN 11)Page 32

Reverse Acting- As the Capacity Control valuerises above the capacity control setpoint, thesesetpoints will protect the compressor by de-creasing the capacity, or if necessary shuttingdown the compressor.

Load Inhibit - This setpoint prevents

the compressor from loading.

Force Unload - This setpoint will ac-tively decrease the capacity of the compres-sor to avoid reaching the warning and shut-down setpoints.

Warning - If the Capacity Control valueis less than (forward) or greater than (re-verse) this setpoint for the Warning Delay, awarning occurs.

Shutdown - If the Capacity Controlvalue is less than (forward) or greater than

(reverse) this setpoint for the Shutdown De-lay, a shutdown occurs.

Each of the four Modes has a set of Safeties andLow Suction Safeties. Additionally, each also hasa Control Channel and is configured with a Con-trol Direction of either Forward or Reverse. TheSafety Setpoints monitor the Control Channel fortheir Mode.

If the Control Direction for a Mode is set to For-ward, its Safeties are activated as the ControlChannels value drops below the Safety Setpoints.

Example:Control Channel = Process TemperatureControl Direction = ForwardSafety Warning Setpoint = 35.0 F

Note:For the above conditions a Warn-

ing will occur if the Process Tempera-ture drops below 35.0 F.

If the Control Direction for a Mode is set to Re-verse, its Safeties are activated as the ControlChannels value rises above the Safety Setpoints.

Example:

Control Channel = Discharge PressureControl Direction = ReverseSafety Load Inhibit Setpoint = 170.0PSIG

Note: For the above conditions a LoadInhibit condition will occur if the Dis-charge Pressure rises above 170.0 PSIG.

LOW SUCTION - The following setpoint boxes areprovided (NOTE: This box will be empty if SuctionPressure has been selected as the Mode control

channel):

Load Inhibit As the suction pressure dropsbelow this setpoint, the compressor is pre-vented from loading.

Force Unload When the suction pres-sure reaches this setpoint, the capacity ofthe compressor will be decreased to avoidreaching the low warning and shutdownsetpoints.

Warning - If the Suction Pressure is lessthan this setpoint for the Warning Delay, a

warning occurs.

Shutdown- If the Suction Pressure is lessthan this setpoint for the Shutdown Delay, ashutdown occurs.

[Shutdown and delay] - If the DischargePressure is greater than or equal to thissetpoint, for the shutdown time delay, thecompressor will be shut down.

[Highest Capacity to Permit Starting] The Slide Valve position must be equal to orless than this setpoint to allow the compres-sor to start.

[Starting Period Before Permitting Capac-ity Increase] This setpoint indicates thetime period after the compressor goes tothe Running State that the Slide Valve willnot be allowed to load.

[Stopping Period for Capacity Unload] When the compressor is commanded tostop, the Slide Valve will unload for this pe-riod, or until the Slide Valve is at or belowthe Highest Capacity to Permit Starting set-point.

[Compressor Automatic Mode MinimumCapacity] When the compressor is Run-ning and the Compressor Mode and Capac-ity Modes are both in Automatic, the SlideValve will be loaded so as to keep the Ca-pacity at or above this setpoint.

[Capacity Unload Assist] A drop downmenu is provided to either enable or disablethis feature. When enabled, this control willbreak the possible hydraulic lock betweenthe slide stop and slide valve that may oc-cur, particularly with large diameter rotors(283 & 355mm compressors). If the Vi (vol-ume ratio) is 4.8 or lower and the slide valve

is 100%, then the slide stop will be givenan increase command simultaneous to theslide valve unload command. Once the slidevalve has moved by a value in percent thatis equal to the Capacity Unload Assist set-point, a decrease command will be given tothe slide stop while the slide valve continues

to receive a unload command. If the Vi orvolume ratio is greater than 4.8 and the slidevalve is 100% the slide stop will be givena decrease signal simultaneous with a slidevalve unload signal. Once the slide valve isseen to have moved by a value in percentthat is equal to the Capacity Unload Assistsetpoint, the slide stop will be allowed tomove back to the proper operating positionbased on compression ratio.

ing control settings will be active:

[Port Value] If the Economizer is On andthe Pressure Input selection is not Disabled,this setpoint is used in calculating the Vol-ume Ratio. A value of 1.6 is used for RXFmodels, and a value of 1.4 is used for RWF

models.

[Pressure Input]

Disabled

Fixed Pressure Setpoint If this isselected, then this setpoint is used tocalculate the Volume Ratio.

Economizer Analog Input If this isselected, then this Input value will beused in calculating the Volume Ratio.

Balance Piston This is a digital output.

[Balance Piston]

Disabled Output is off.

Enabled When Enabled, and if thecompressor is running, the output iscontrolled by comparing the Slide Valvepositions to the On and Off setpoints

[Ignore Delay] The length of time that theBalance Piston safety checks are not per-formed.

[Fail Delay] Delay Period for the BalancePiston safety checks.

[Oil Log]

Disabled Oil Log is disabled.

Enabled If for the Oil Log Delay set-point period, the oil pump has been onand the compressor is Off or Startingwithout going into Running, an Oil Logshutdown will occur.

[Oil Pump Unload Assist]

Disabled Oil Pump Unload Assist isdisabled.

Enabled Oil Pump Unload Assist isenabled.

[Main Oil Injection]

Is Above (Setpoint) - The Main Oil In-jection output will energize when theDischarge Temperature exceeds thissetpoint.

For (Delay) Once the Main Oil Injec-tion output has been energized by theabove setpoint, it will remain energizedfor this amount of time.

SETPOINTS - Package Safeties

ACCESSING:

DESCRIPTION:Package safeties are important for the safe operation of the compressor.

Setpointsetpoints

Packa eackage

The following pull-down menus and setpoint boxes maybe shown here:

Low Oil Separator Temperature:

[Warning] - If the Oil Separator Tempera-ture is less than or equal to this setpoint,for the warning alarm time delay, a warningoccurs.

[Warning Delay]- The minimum timein seconds that the Oil Separator Tem-perature is less than or equal to theLow Oil Separator Temperature Warn-ing setpoint before notification of thewarning.

[Shutdown] - If the Oil Separator Tempera-ture is less than or equal to this setpoint, forthe shutdown time delay, the compressorwill shut down.

[Shutdown Delay] - The minimumtime in seconds that the Oil SeparatorTemperature is less than or equal to theLow Oil Separator Shutdown setpointbefore the compressor will shut down.

Low Oil Temperature:

[Warning] - If the Oil Temperature is lessthan or equal to this setpoint, for the warn-

ing time delay, a warning occurs.

[Warning Delay] - The minimum timein seconds that the Oil Temperature is

less than or equal to the Low Oil Warn-ing setpoint before notification of thewarning.

[Shutdown]- If the Oil Temperature is lessthan or equal to this setpoint, for the shut-down time delay, the compressor will shutdown.

[Shutdown Delay] - The minimum timein seconds that the Oil Temperature isless than or equal to the Low Oil Shut-down setpoint before the compressorwill shut down.

High Oil Temperature:

[Warning]- If the Oil Temperature is great-er than or equal to this setpoint, for thewarning time delay, a warning occurs.

[Warning Delay]- The minimum timein seconds that the Oil Temperature isgreater than or equal to the High OilTemperature Warning setpoint beforenotification of the warning.

[Shutdown] - If the Oil Temperature is

greater than or equal to this setpoint, forthe shutdown time delay, the compressorwill shut down.

[Shutdown Delay] - The minimumtime in seconds that the Oil Tempera-ture is greater than or equal to the High

Oil Temperature Shutdown setpoint be-fore the compressor will shut down.

Low Oil Pressure:

[Warning]- If the Oil Pressure is less thanor equal to this setpoint, for the warningtime delay, a warning occurs.

[Warning Delay] - The minimum timein seconds that the Oil Pressure is lessthan or equal to the Low Oil PressureWarning setpoint before notification ofthe warning.

[Shutdown] - If the Oil Pressure is less thanor equal to this setpoint, for the shutdowntime delay, the compressor will shut down.

[Shutdown Delay] - The minimumtime in seconds that the Oil Pressureis less than or equal to the Low OilPressure Shutdown setpoint before thecompressor will shut down.

High Filter Pressure:

[Warning] - If the Filter Pressure is greater

than or equal to this setpoint, for the warn-ing time delay, a warning occurs.

[Warning Delay]- The minimum timein seconds that the Filter Pressure isgreater than or equal to the High FilterPressure Warning setpoint before noti-fication of the warning.

[Shutdown]- If the Filter Pressure is great-er than or equal to this setpoint, for theshutdown time delay, the compressor willshut down.

[Shutdown Delay] - The minimum timein seconds that the Filter Pressure isgreater than or equal to the High FilterPressure Shutdown setpoint before thecompressor will shut down.

[High Level Shutdown Delay] - The time inseconds to delay after the High Liquid Levelinput is energized before the compressorwill shut down.

[Low Oil Level Delay]- The time that mustelapse before the Low Oil Level Shutdowncan be initiated.

[Oil Pump Lube Time Before Starting] -The amount of time that the compressorwill be delayed from starting to allow theOil Pump to properly lube the compressorcomponents.

[Dual Pump Transition Time] - If enabled.

The lead pump is the pump selected to bethe first pump to run. If the lead pump hasa pump auxiliary failure, an alarm messageis issued and the other pump will be turnedon. If the compressor has a Low Oil Pres-sure Warning failure, the second pump willbe turned on; then after a 30 seconds delay,the lead pump will be turned off. If while thecompressor is running the second pump hasan auxiliary failure or Low Oil Pressure is en-countered, a shutdown message and actionis issued.

Pull Down:

With this option enabled, the Suction Pressurecan be slowly lowered in steps. Slowly walkingthe pressure down prevents rapid drops in sys-tem pressure that
