A. TROUBLESHOOTING GUIDE

Before applying power to the VISSION MicroController panel, all wiring to the panel should beper NEC. Specifically check for proper voltage and that the neutral is grounded at the source.An equipment ground should also be run to the panel.

In the event of a problem with the Vilter VISSION MicroController, the help screen, along with

your electrical drawings, will help to determine the cause.

PROBLEM POSSIBLE SOLUTION

1. Vission MicroController does notboot up, no lights on any boards.

a) Check to make sure 120VAC is run to L1 on the Relayboard. This is the board on the inside left back of the

panel. L1 is the fifth connector down from the top and thetop terminal. The neutral should be brought to any N onthe relay board.

b) Check F1 fuse on relay board.c) Check F1 fuse on the power supply, located on the front of

the door. If all of the above is okay, the power supply may

be bad. Check DC voltages on the single board computerinterface board, which is the big green board above the

power supply. Along the right edge of this board, justabove the power supply connector J14, are test points. If

proper voltages are not located at these test points, thepower supply may be faulty.

2. Vission MicroController appearsto be booted, lights seen onboards and E-stop switch, butno touch screen is evident.

a) Check cable connections located on the LCD Inverterboard. This board is located inside the door on the LCDtouch screen back plane above the single board computer.The connector with the pink and white wires, located on theleft center of the board is the power supply to the board.

The connector on the top right of the board with the blackwires has the data wires. If these are inserted correctly,the problem could be bad solder joint on the LCD Inverterboard or a component failure.

3. Vission MicroController boots upbut all data temperatures andpressures are zeroed and do notupdate.

a) Check Analog board jumpers J41 & J46. They should beon pins 1 & 2 (center and right pins).

b) Check the upper DIP switch on the analog board. Thisidentifies the node address of the Analog board. Onlyswitch #1 should be on, the rest off.

c) The Vission MicroController has (2) boards runningseparate programs. The Analog board located inside the

panel on the back right calculates pressures, temperatures,amps and monitors inputs. The single board computerrequests this data for action and display. The single boardcomputer will instruct the Analog board to activate outputsor relays as needed. Communication between the boardsis RS-485 running at 115200 baud. The cable is basically

phone cable with phone jack style connectors. The


7/70



connector to the single board computer is on the touscreen back panel and is labeled RS-485 Com2 to AnaloBd. The connector on the Analog board is located on tbottom of the board. There are 2 connectors on the analboard, either one can be used.

If this cable is open or disconnected, there will be ncommunications between the boards. The top two grelights on the Analog board (D10 & D11), located on thbottom left of the board, will be off. The pressures atemperatures will not update. Ensure the cable is pluggin correctly. Try rebooting again. If the problem persistry moving the cable on the Analog board to the othconnector. If not successful, try a different cable on t

Analog board to the other connector on the board. If nsuccessful, try a different cable. Any phone style coshould work. If neither of these help, contact the VilHome Office.

4. On Bootup, the message Thedirectory entry for VSSPROG.retspecifies an incorrect file size.Do you want this problemautomatically repaired now?

a) Select YES and the program will continue booting.

5. A bank of pressure ortemperature channels no longerfunction.

a) There are four fuses on the Analog board that limit thcurrent on the 24VDC to the Analog channels. The fusare 500 milliamp, located near the power suppconnectors and brown in color. LEDs next to the fusgive a visual indication of the status of the fuse, howeveris best to pull the fuse and check them with an ohmmete

If any are blown, find the shorted device that is responsibfor the blown fuse and replace.

F1 protects the +24VDC supply to the pressutransducers and relays.

F2 protects the 12VDC supply which is subregulated 5VDC required for multiplexers, analog to digital converand temperature channels.

F3 protects the +12VDC supply which is subregulated

+5VDC, required for multiplexers, analog to digiconverters, and temperature channel.

F4 protects the main +5VDC supply required for most the components on the analog board.

If F1 blows, the pressure transducers will produ


8/70



erroneous readings and the relays on the relay board willdrop out (de-energize). If F2, F3 or F4 blows, all analogreadings will be affected.

6. A pressure channel reads anegative number over 140.

a) This indicates the transducer wiring or transducer is eitheropen or shorted. Check wiring to print.

b) Check fuses F1, F2, F3 and F4 on analog board.

7. A temperature channel reads a

large negative value over 400.

a) This indicates the RTD wiring or RTD is open. Checkwiring to print.

b) Check fuses F1, F2, F3 & F4 on analog board.

Pressure Units Select units of measure for pressure readings. Choices are psi, kg/cm2 and kPa. Affects pressures displayed on main screen. On other screens, units aredisplayed in psi. On the main screen with psi selected, negative gauge pressures willdisplay as inches of mercury vacuum with the unit Hg. On other screens, negativenumbers are scaled as Hg.

Temperature Units Select units of measure for temperature. Choices are Fahrenheit orCelsius.

Refrigerant Select type of refrigerant used in compressor. Current choices are R717(Ammonia), R22, R134A and R290 (Propane).

Anti-Recycle The operator can select from the following AntiRecycle options: True,Accumulative, Modified, or Hot Starts. These select the strategy used to prevent excessivestart/stop cycles of the compressor. Timers and counters used to enforce anti-recycling areadjusted and monitored in the Compressor Timer Settings screen, reached from the Menuscreen. Help for the Timer Settings screen explains how the different settings and

strategies operate.

Compressor Control Via Operator can choose the method or mode of compressorcontrol. This determines which measured variable is used in making loading (capacitycontrol) decisions. The choice selected here determines which setpoints are madeavailable for adjustment on the Compressor Control Setpoints screen.

Delete Operator Operator can choose to delete operator names from the authorizedoperator listing. A name in the list is selected by touching it. The selected name will bedeleted from the list when this button is pushed. If you delete all the names (besidesVILTER), be sure you add at least one before leaving this screen.

Add Operator This button will take you to the screen pictured in Figure 2. The buttonopens a dialog for entry of a new name/password pair. Nothing (leaving the password textbox blank) is a legal password. The password is not obscured as it is typed in, sountrusted parties should not be permitted to view the screen during entry. The password isnot confirmed with a repeat entry, so verify it visually before pressing okay. Up to 25name/password pairs can be added. The Operator Name list box will acquire a scroll barwhen it fills.

Modbus Slave Network Address When multiple Vission MicroControllers are connectedon a Modbus Network, each controller must have a unique address from the other Vissions

on the network. Duplicate node addresses are not allowed. The node address of eachVission is determined through the SETUP menu. The Vission that will initiate allconversation on the network MUSTbe defined as node 100 (this is defined as the masternode). All other node numbers should be in the range of 101 through 174.

This must be set when the extra special port (Com4) is used to control or monitor thecompressor via Modbus. It also must be set when the multi-compressor sequencing


11/70



feature is used. Even though Ethernet is used for the comms, this address establishes thecompressors identity and role in the sequencing logic.

Reset After Power Fail When Auto is selected, the compressor will attempt to restart onpowering up if it was running in Auto when powered down and enabling conditions aremet. When Manual is selected, the compressor powers up into the Stop mode and anexplicit command to run is required from an operator or comms channel.

Min Run Capacity When enabled, the Minimum Run Capacity setting on the AdditionCompressor Setpoints screen operates as described in the help for that screen. Whenmultiple compressor sequencing is used, selecting Disable here does not interfere with useof the Min Run Capacity setting in the sequencing logic.

Setpoint #1 Oil Pump, Setpoint #2 Oil Pump For single stage and high stage operationpart time or normal oil pump function is used. The oil pump is shut off after dischargepressure has risen sufficiently to drive oil injection. Oil pump operating mode isindependently settable for setpoint groups #1 and #2.

Liq Inj Solenoid Control Determines which measured temperature is used for control ofthe liquid injection solenoid. This setting only applies when liquid injection is used for oicooling.

Slide Movement Alarm enable and disable buttons permit selecting whether an alarmshould be generated when failure of slides to move is detected.

These screens enable the operator to view and adjusts settings that affect compressor control.

From the Setup screen (Figure 2), the operator can choose the method or mode ofcompressor control:

Compressor Control Via Suction PressureProcess TemperatureDischarge Pressure

Once the method is chosen, the appropriate setpoints are then displayed on the CompressorControl Setpoints screen. The compressor will decide when to increase or decrease capacity

by comparing the controlled variable to the setpoints. The maximum on time and minimum offtime settings for slide actuator motors can be used to reduce hunting or improve responsetime. The default settings of 3 and 20 seconds respectively, provide good operation over awide range of conditions.

Also on this screen, the following buttons are displayed:

Event List Provides a chronological event listing. This includes log in and setpoint changesperformed by operators on the compressor package.

Chart Provides a line graph showing process values over a range of time.

Auto Places the capacity slides into automatic mode. In automatic mode, the capacityslide moves control setpoint information.

Manual Places the capacity slides into manual mode. In manual mode, the capacity slidemoves direct input from the operator.

Setpoints on this screen:

Suction Pressure On/Off The compressor will automatically cycle ON and OFF at thesetpoints entered. Suction Pressure On/Off control is only active if the Compressor ControVia Suction Pressure option is selected on the Setupscreen (Figure 2). If a compressoshutdown is desired on a suction pressure drop and a manual reset is required, set theOFF value below the Low Safety Pressure Safety Trip value. This will shut down the uni

and a reset will be required to restart it.

Suction Pressure Capacity Increase The capacity of the compressor will increase whensuction pressure is at or above the Increase ON setpoint, and the increase off timer hascycled. Capacity will continue to increase until the Suction Pressure Capacity IncreaseOFF setpoint is reached. If closer system control is desired, set the ON and OFF setpointsat the same values. This will essentially eliminate any differential between the ON andOFF setpoints.

Suction Pressure Capacity Decrease The capacity of the compressor will decreasewhen suction pressure is at or below the ON setpoint, and the decrease off timer has

cycled. Capacity will continue to decrease until the Suction Pressure Capacity DecreaseOFF setpoint is reached. If closer system control is desired, set the ON and OFF setpointsat the same values. This will essentially eliminate any differential between the ON andOFF setpoints. While this setting is only available for adjustment on the Control Setpointsscreen when the Compressor Control Via Suction Pressure option is selected on the Setupscreen (Figure 2), it has an override effect when control is via process temperature asdescribed below.

Capacity Control F On/Off The compressor will automatically cycle ON and OFF at thesetpoints entered. Capacity Control F On/Off is only active if the Compressor Control viaProcess Temperature option is selected on the Setup screen (Figure 2). If compresso

shutdown is desired on a process temperature drop and a manual reset is required, set theOFF value below the Low Control Temperature safety trip value. This will shut down theunit and a reset will be required to restart it.

Capacity Control F Increase The capacity of the compressor will increase whenprocess temperature is at or above the ON setpoint, and the increase off timer has cycledCapacity will continue to increase until the Capacity Control F Increase OFF setpoint is


18/70



reached. If closer system control is desired, set the ON and OFF setpoints at the samevalues. This will essentially eliminate any differential between the ON and OFF setpoints.Process temperature control of the capacity is active only if the Compressor Control ViaProcess Temperature option is selected on the Setupscreen (Figure 2).

Process Temperature Control provides for a Suction Pressure Override feature. If thesuction pressure should drop below the Suction Pressure Capacity Decrease OFF setpoint,the Suction Pressure Capacity Decrease OFF setpoint will override the Capacity Control FIncrease and prevent the compressor capacity from increasing (loading). If the suction

pressure should continue to decrease below the Suction Pressure Capacity Decrease ONsetpoint, the compressor capacity will be forced to decrease until the suction pressure is

just above the Suction Pressure Capacity Decrease ON setpoint. This will help stabilizethe suction pressure, allowing for the process temperature to be gradually pulled down.The Suction Pressure Capacity Decrease ON and OFF setpoints can be viewed oradjusted by temporarily selecting Processor Control Via Suction Pressure on the Setupscreen (Figure 2).

Capacity Control F Decrease The capacity of the compressor will decrease when theprocess temperature is at or below the ON setpoint and the decrease off timer has cycled.Capacity will continue to decrease until the Capacity Control F Decrease OFF setpoint isreached. If closer system control is desired, set the ON and OFF setpoints at the samevalues. This will essentially eliminate any differential between the ON and OFF setpoints.

B. Level 1 Access Additional Compressor Setpoints

F I G U R E 1 1 . A D D I T I O N A L C O M P R E S S O R S E T P O I N T S S C R E E N

High Discharge Pressure Unloading Setpoints 1&2 Active in Suction Pressure orProcess Temperature Capacity Control mode. These setpoints limit the compressor fromloading at high discharge pressure conditions. They override the Suction Pressure orProcess Temperature Capacity Control setpoints. The capacity of the compressor wildecrease when the discharge pressure is at or above the cut-in set point. When the cutousetpoint is reached, the compressor will stop from unloading any further.

Motor Amp. Load Limit Setpoints 1&2 This control limit is the motor full load currentdraw and the maximum current draw. This control limit will only prevent the compresso

from loading and does not shut down the compressor if the maximum current draw setpoinis exceeded. The actual values entered may depend on particular circumstances. Thefunction of the setpoint is as follows:

If the motor is operating at the full load amperage (FLA) setting, the compressor isprevented from loading. If the motor amps exceed the MAX setpoint, the compressor is


20/70



forced to unload until the current is at 1.0625 times above the FLA setting. If the motorbeing used has a service factor below 1.0625, use a value for the FLA that is 10% lowerthan the MAX value.

Oil Separator Heater Temperature This control limit determines when the oil separatorheater is energized. A decrease in oil separator temperature below the cut-in setpointenergizes the oil separator heater. On an increase in oil separator temperature above thecutout setpoint, the oil heater is de-energized.

Oil Pump Restart To determine cut-in and cut-out values for the pressure ratios, take theabsolute discharge pressure (PSIA), and divide it by the absolute suction pressure (PSIA).If the pressure ratio is below cut-in setpoint value, the oil pump will restart and stay on untilthe pressure ratio increases above the cutout setpoint. This enables a high stagecompressor with a part time oil pump to temporarily operate under conditions requiring afull time oil pump.

Capacity Lag Step The lag step value determines the increment the lag compressor isallowed to load or unload on a call for capacity increase or decrease from the leadcompressor. This setpoint is active only when the Lead/Lag Enable operator option isselected.

Capacity Slide Adjustment Range This control limit determines the capacity range thevolume Slide Adjustment factor will be active. The factor will be active from 0% capacity

and will be deactivated when the cutout setpoint is reached. On a decrease in capacitybelow the cut-in set point, the factor will be active.

Minimum Run Capacity The Minimum Run Capacity is the minimum capacity thecompressor will be allowed to run at. When the compressor is started, it will be loaded tothe Minimum Run Capacity control setpoint minus 5%. This is done to prevent the capacitycontrol from hunting if the load is not great enough to keep the compressor capacity at theMinimum Run Capacity setpoint. On a call for unloading, the compressor will unload until itreaches the Minimum Run Capacity control setpoint. It will remain there until the suction

pressure reduces and the compressor cycles off on the Suction Pressure On/Off controlsetpoint.

Economizer Solenoid This control limit determines when the economizer solenoid isenergized. When the percentage of compressor capacity reduces below the EconomizerSolenoid cut-out set point, the solenoid is energized.

Current Transformer Ratio The value entered must agree with the Current TransformerRatio on the current transformer being used. The current transformer is mounted in the


21/70



compressor motor conduit box. The ratio is stated as the ratio of measured current to anominal full scale current in the secondary of 5 amps; only the first of these is entered. Forexample, if the ratio reads 250/5, enter 250.

Low Suction Pressure Load Limit Active in Discharge Pressure Capacity Control modeonly. These setpoints limit the compressor from loading at low suction pressure conditionsThey override the discharge pressure capacity control setpoints. When the cutout setpoinis reached (at or below setpoint), the compressor will not be allowed to load any further. Ithe suction pressure continues to fall, the capacity of the compressor will decrease whenthe suction pressure is at or below the cut-in set point. It will stop decreasing when thesuction pressure rises to a point that is just below the cut-out set point.

Low Suction Pressure Setpoints 1&2 This is the low suction pressure safety. Thissafety is active in both temperature and pressure control modes. An alarm or trip will beactive on a drop in suction pressure below the setpoint value.

High Discharge Pressure Setpoints 1&2 This is the high discharge pressure safety.The alarm or trip will be active on a rise in discharge pressure above the setpoint value.

Low Suction Temperature This is the low suction temperature safety. The alarm or tripwill be active if the suction temperature should drop below the setpoint value.


23/70



High Discharge Temperature This is the high discharge temperature safety. The alarmor trip will be active if the discharge temperature should rise above the setpoint value.

Low Oil Separator Start Temperature This is the starting low oil separator temperaturesafety. The compressor is prevented from starting or running if the oil in the separator isbelow the trip value. After a time delay (Oil Separator Temperature Safety Changeover)this safety is deactivated and the Lo Oil Separator Run Temperature is the active setpoint.

Low Oil Separator Run Temperature This is the running low oil separator temperaturesafety. After a time delay (Oil Separator Temperature Safety Changeover), the Lo OiSeparator Start Temperature is bypassed and Lo Oil Separator Run Temperature is theactive setpoint. The alarm or trip will be active if the oil temperature of the separator dropsbelow the setpoint value.

Low Oil Injection Temperature This is the low oil injection safety. The alarm or trip wilbe active if oil injection temperature drops below setpoint value after a time delay (OiInjection Temperature Safety Changeover).

High Oil Injection Temperature This is the high oil injection temperature safety. Thealarm or trip will be active on a rise in oil injection temperature above the setpoint value.

Prelube Oil Pressure If the oil pressure does not rise above the reset setting for a timeexceeding the Minimum Compressor Prelube Time and the pump runs longer than thePrelube Pump Time Limit, an alarm or trip will occur. These time limits are set on theCompressor Timer Setpoints screen. Prelube oil pressure is defined as the amount thatthe oil pump drives manifold pressure above the discharge pressure.

Low Oil Pressure This is the running oil pressure safety. An alarm or trip will be active ifthe oil pressure should drop below the setpoint value. This occurs once the Oil PressureBypass timer has expired. The time limit is set on the Compressor Timer Setpoints screen.For the single screw compressor, oil pressure is defined as manifold pressure minussuction pressure.

High Filter Differential Pressure Start This safety setpoint is active when thecompressor is in the start cycle. An alarm or trip will be active if the filter inlet pressureexceeds the filter outlet pressure by the setpoint value.

High Filter Differential Pressure Run This safety setpoint is active when thecompressor is in the run cycle. An alarm or trip will be active if the filter inlet pressureexceeds the filter outlet pressure by the setpoint value.

High Motor Amps This safety setpoint is active after the Volume Decrease At StartTimer expires. This timer is not user settable, and in standard applications, is 15 seconds.

A trip will occur if the motor amperage exceeds the safety setpoint value. The setpointshould be set at 125% of the motor full load amperage.

To change a timer setting, you must Logon to Edit first. Push the Set button then push onthe timer setpoint value you wish to change. After the setpoint is changed, press the Refreshbutton. This will refresh the Current window, which shows the elapsed time of the timers.

Capacity Decrease At Start At compressor startup, the capacity motor is held atminimum position for this time period. After the timer expires, the slide is free to move inaccordance to the system demands.

Compressor Starter Auxiliary Contact Bypass The auxiliary motor starter contact isbypassed for this period during startup. If it does not close after the time has cycled, thecompressor will shut down and a motor overload failure will be displayed. Likewise isometime after the delay, the auxiliary contact should open, the same failure screen displaywill be shown.


26/70



Volume Slide Adjustment Timer This timer determines the intervals the volume slide isadjusted. If the volume slide is between 2% & 7% away from the desired volume ratio,the motor is pulsed once toward the desired volume. If the volume slide is more than 7%away from the desired value, the volume slide motor is continuously energized until thevalve is within 2% of the desired value. If the actual position is within 2% of the desiredvalue, no adjustment will be made.

Minimum Compressor Prelube Timer This is the length of time the oil pump will runafter establishing the Prelube Oil Pressure, to prime oil circuit before starting thecompressor.

Oil Pressure Bypass At Compressor Start This timer bypasses the Low Oil Pressurelimits. The timer starts when the compressor starts. After the timer has cycled, the Low OilPressure setpoint is active.

Prelube Oil Pump Time Limit This timer puts a limit on how long the prelube oil pump isallowed to run without establishing the Prelube Oil Pressure.

Filter Differential Pressure Safety Changeover This timer bypasses the Hi Run FilterDifferential Pressure setting during start, to allow the Hi Start Filter Differential Pressure toprotect against High Filter Differential during start. After the timer has cycled, the Hi RunDifferential Pressure Safety is active.

Low Oil Separator Level Bypass Timer This timer bypasses the low oil level switch formomentary drops in the oil level. If the switch is still open after the Low Oil Separator LevelBypass Timer has timed out, the compressor will be shut down and an alarm will bedisplayed. This timer is available if the unit is equipped with a low oil separator float switch.The oil level switch is standard on all liquid injection units and optional on all others.

Auto Restart After Power Failure This timer forces the microprocessor to wait for theset time period after a power failure before starting the compressor unit. By staggering thetime settings, the compressors can be allowed to start automatically, one at a time, after a

power failure. This prevents excessive loads on the power system that could be caused byall of the equipment coming online at the same time. The Power-Up Auto Start operatoroption must be selected on the Setup screen (Figure 2) for this option to be active.

Oil Separator Temperature Safety Changeover This timer allows Low Oil SeparatorStart Temperature Safety setpoint to protect the compressor against cold oil during starting.

After the timer has cycled, the Low Oil Separator Run Temperature is then active.

Low Oil Injection Temperature Bypass This timer bypasses the Low Oil InjectionTemperature Safety Setpoint during start-up. After the timer cycles, the Low Oil InjectionTemperature Safety is set.

Hot Starts / Hr Counter This counter counts compressor starts. After every start, a one-hour timer is reset and starts timing. If the timer times out, the hot starts counter is reset.When the counter reaches its preset value, it will not allow another compressor start until


27/70



the one-hour timer times out and resets the counter. In other words, the hot starts countewill be reset when the time between compressor starts total one hour. This counter allowsrepetitive compressor starts, but once the counter has reached its set point, it requires aone-hour window between compressor starts in order for the counter to be reset.

True Anti-Recycle Timer Once the compressor turns off, the timer will keep thecompressor off for the setting of True Anti-Recycle Timer. This timer is used to prevenshort cycling of the compressor.

Accumulative Anti-Recycle Timer This timer also forces a specified time betweencompressor starts. When the compressor starts, the timer reset, starts timing andaccumulates running time. Once the compressor shuts down, it will not be allowed torestart for the remainder of the time left on the Accumulative Anti-Recycle Timer. Unlikethe True Anti-Recycle Timer, if the compressor has run for a time period that exceeds thesetpoint of the Accumulative Anti-Recycle Timer, then when the compressor shuts down, iwill be allowed to restart immediately.

The compressor restart options (Hot Starts or Anti-Recycle Timers) are selected from theSetupscreen (Figure 2). One additional Anti-Recycle Timer that can be selected from theSetupscreen (Figure 2) is the Modified Anti-Recycle Timer.

Modified Anti-Recycle Timer Normally, this anti-recycle timer will function as a TrueAnti-Recycle Timer. However, if the operator presses the stop button, or if a failure occursthe anti-recycle timer switches functions and acts as an accumulative type anti-recycletimer. It will allow the compressor to restart when the accumulated runtime and the presenoff time meets or exceeds the setting of this timer.

This screen allows the operator to setup a sequencing network. Current, the Vission iscapable of sequencing 5 compressors. In order for a Vission to participate on the network, imust have a unique address from the other Vissions on the network. Duplicate nodeaddresses are not allowed. The node address of each Vission is done through the Setupmenu (Figure 2).

The Vission which will initiate all conversation on the network MUST be defined as node 100.This is defined as the master node. All other node numbers should be in the range of 101through 174.

Ethernet Peer To Peer In addition to having unique node addresses, all compressors onthe Ethernet network must have unique IP addresses and unique names. These areentered from the Think and Do Configuration Utility screen, accessed from the VILTERONLY screen. The Ethernet IP addresses of each of the five compressors listed arerequired to be:

Equipment: Ethernet IP AddressCmp#1: 10.8.0.73Cmp#2: 10.8.0.74Cmp#3: 10.8.0.75Cmp#4: 10.8.0.76Cmp#5: 10.8.0.77

The Compressor Sequencing screen only needs to be setup on the Master node. Theelements of this screen are:


30/70



Equipment Allows the operator to select the size of each compressor. This informationis used to make sequencing decisions based on the CFM of the compressor. A valid sizeMUST be chosen for a compressor to participate in sequencing. This field also allows theoperator to change the name of each of the five compressors listed.

Node These node address fields tell the sequencing algorithm which the Vission will beparticipating in the sequencing network. Input the node addresses of each Vission,participating on the network, in these fields.

NOTE:The node addresses for each Vission panel are defined and entered under the Setup screen(Figure 2) at each individual Vission panel.

Central Off/On Buttons These buttons indicate whether the compressor has beenselected to operate under Central Control. If the button reads On, the compressor will beincluded in the Central Control System. If the button reads Off, the compressor will not beincluded in the Central Control system. Pushing once on the button will toggle the buttonbetween Off and On.

Priority The Priority fields are used to assign the compressor priority for Central Control.The lower the priority number, the greater the priority of the compressor. Priority #1compressor is the highest priority compressor. Compressors with higher priority numberswill be lag compressors. A compressor with a priority of 1 will be considered the leadcompressor. The suction pressure of priority #1 compressor is used to control the system

pressure.

Step This field sets the amount of capacity change that will occur when a compressor isloading or unloading.

NOTE:Because of the method used to position the slide valve, and the method used to determinewhen the slide valve position is close enough to the target value, the step value should neverbe less than 5%.

Min Cap The Minimum Capacity is the lowest capacity, in percentages, that thiscompressor is allowed to reach during operation. If the system needs to remove additionalsystem capacity, it may shut a compressor off.

Max Cap The Maximum Capacity is the highest capacity, in percentage, that this

compressor is allowed to reach during operation. If the system needs to increase capacityafter this compressor has reached its maximum, it may turn on another compressor.

Stop Tmr The Stop Timer (in seconds) is the amount of time the system must hold acompressor at minimum capacity before the compressor can be shut off.


31/70



PRESSURE SETPOINTS:

The 7 pressure setpoints are used to control the system pressure. With the exception of theStart #1 and Start Lag setpoints, all other setpoints must be in decreasing pressures from the

previous value.

Start #1 The Start #1 pressure setpoint is the system pressure at which the Priority 1compressor will be started.

Start Lag The Start Lag pressure setpoint will only start the lag compressor, and onlyafter the lead compressor has reached the Max Cap value, and the Machine Start Timerhas timed out. The Lead compressor is normally priority, unless it is not available to stardue to waiting hot starts, safety trips, etc.

Load Rate 2 If the system pressure exceeds the Load Rate 2 pressure setpoint for thetime specified in the Load Rate 2 Timer, Central Control will attempt to increase thecapacity of the system.

Load Rate 1 If the system pressure exceeds the Load Rate 1 pressure setpoint for thetime specified in the Load Rate 1 Timer, Central Control will attempt to increase thecapacity of the system.

Unload Rate 1 If the system pressure falls below the Unload Rate 1 pressure setpoint forthe time specified in the Unload Rate 1 Timer, Central Control will attempt to decrease thecapacity of the system.

Unload Rate 2 If the system pressure fails below the Unload Rate 2 pressure setpoint forthe time specified in the Unload Rate 2 Timer, Central Control will attempt to decrease the

capacity of the system.

Stop If the system pressure falls below the Stop setpoint, Central Control will immediatelytry to shut down the lowest priority lag compressor. If there is only one compressorunning, Central Control will shut down.

CAP Load Timers These timers are directly related to the setpoint values describedabove. The timers are the minutes and seconds that the Central Control algorithm will holdbefore deciding on an action. The CAP Load Rate Timers are related to the appropriateLoad 1 and 2 increase setpoints described above.

CAP Unload Timers The Capacity Unload Rate Timers are similar to the timersdescribed above, however, they work to decrease system capacity. The CAP Unload RateTimers are related to the appropriate Unload Rate 1 and 2 decrease setpoints described

previously.

Machine Start Time This timer is the time the system will wait until another compressoris started in an attempt to increase capacity.

The calibration procedure of the actuator is done in two steps:1) the actuator control module calibration is performed. Instructs the actuator motor control

module to the rotation minimum position and rotational maximum position of the motor.The actuator motor control module puts out 0 volts DC at the rotational minimum position ofthe motor and 5 volts DC at the rotation maximum position of the motor.

2) After the actuator motor control module has been calibrated, the micro-controller channelcorresponds to the actuator motor. Either the capacity or volume channel has to be

calibrated.


41/70



Actuator Motor Control Module Calibration Procedure

1. Turn power off to micro-controller panel completely.

2. With new actuator motors already mounted, wire new actuators per the wiring diagramsshown in Figures 22, 23 or 24. Use the already installed electrical conduit to run thenew cables. The old electrical wires can be used to pull the new cables through theconduit from the actuator to the control panel. Do not use the same conduit for theDC and AC cables. Do not connect the Power Cables (Yellow Turck cable) or thePosition Transmitter Cables (Gray Turck cable) to either of the actuator motors yet.

Because the actuator motors have not been calibrated, the transmitter output of theactuator motor will fluctuate wildly until they are calibrated. To prevent damage toactuator motors, do not connect the Power Cable (Yellow turck cable) or the PositionTransmitter Cable (Gray Turck cable) until instructed to do so in this procedure.

Procedure to Calibrate the Capacity Actuator Motor and the Capacity Channel

1. Open the plastic cover of the capacity motor by removing the four #10 Pan HeadPhillips screws. Gently lift the cover and tilt it toward the Turck connectors. Raise thecover enough to be able to press the blue calibrate button and be able to see the redLED on the top of the assembly.

CAUTIONHandling the cover too aggressively may break the four wires attaching the covermounted connector to the circuit board.

2. Go to Menu on the main screen, then to Slide Calibration screen on the microcontroller.

3. At this point, Slide Valve Calibration screen appears. Once this menu appears, youcan now safely connect the Power Cable (Yellow Turck cable) and the PositionTransmitter Cable (Gray Turck cable) to the Capacity motor. Press INC or DEC tomove the slide valves to check the rotation. (See Table 1 for proper shaft rotation.)

If for any reason the Increase or Decrease command on the panel does not correspondto the slide increase or decrease, swap the blue & brown wires of the Yellow Turckcable in the control panel to reverse the rotation of the motor.

4. Quickly press and release the BLUE CALIBRATION BUTTON on the actuator motoronce. This instructs the actuator motor to enter the calibration mode. The red LEDwill begin flashing.

5. Use the DEC button on the micro-controller panel to drive the capacity slide to itsminimum mechanical stop position.


42/70



CAUTIONDO NOT CONTINUE TO ENERGIZE THE ACTUATOR MOTOR AFTER THE SLIDE HASREACHED THE MECHANICAL STOP. Doing so may cause mechanical damage to themotor or shear the motor shaft key.

When the slide has reached the mechanical stop position, use the INC button to pulsethe motor so the capacity slide is just off of its minimum position and there is notension on the motor shaft.

6. Quickly press and release the BLUE CALIBRATION BUTTON on the actuator motoronce. The red LED will now flash at a slower rate. This instructs the actuator motorthat this point is the minimum slide position. This point will correspond to 0 volts

AFTER the actuator calibration procedure completion.

7. Use the INC button on the micro-controller to drive the capacity slide to its maximummechanical stop position.

CAUTIONDO NOT CONTINUE TO ENERGIZE THE ACTUATOR MOTOR AFTER THE SLIDE HASREACHED THE MECHANICAL STOP. Doing so may cause mechanical damage to themotor or shear the motor shaft key.

When the slide has reached the mechanical stop position, use the DEC button to pulsethe motor the capacity slide is just off of its maximum position and there is no tensionon the motor shaft.

8. Quickly press and release the BLUE CALIBRATION BUTTON on the actuator motoronce. The red LED will stop flashing. This now instructs the actuator motor that this

point is the maximum slide position. This point corresponds to 5 volts. The actuatorcalibration procedure is complete.

Now the Capacity Channel can be Calibrated

1. Use the DEC button to drive the actuator motor back towards its minimum position.Watch the millivolt readout on the micro-controller screen. When the millivolts in theCurrent window above the Set Min button reads approximately 500 millivolts,

discontinue pressing the DEC button. Now use the DEC and INC buttons to positionthe slide until a value close to 300 millivolts is on the screen. At this point, press theSet Min button in the Capacity Slide Valve Potentiometer window. This tells the micro-controller where the minimum millivolt position is. Realize that the Current Capwindow will show a value, but it has no meaning at this point.


43/70



2. Use the INC button to drive the actuator motor towards its maximum position. Watchthe millivolt readout on the micro-controller screen. When the millivolts readapproximately 9200 millivolts, discontinue pressing the INC button. Now use the INCbutton to pulse the slide until the millivolt readout saturates or stops increasing. Thisis around 9500 millivolts. At this point, pulse the DEC button until the millivolts just starto drop. This is the point where the channel drops out of saturation. Press the SeMax button. Calibration of the slide is completed AFTER pressing the Main button, toexit the Slide Calibration screen. If you re-enter the Slide Calibration Screen, thecorrect value will be displayed in the Current Cap window and on the Main screen.

3. At this point, the capacity motor will energize automatically and drive the capacity slideback to its minimum position. The calibration for the capacity slide is completed.

4. Gently lower the plastic cover to where it contacts the base and o-ring seal. Aftermaking sure that the cover is not in a bind, gently tighten the four #10 Phillips screws.

CAUTIONIt is possible to crack the plastic cover by overtightening the screws.

Repeat the same procedure for the Volume slide motor.
