2 - GENERAL DESCRIPTION

2.1 - GENERALITIES

PRO-DIALOG is a system for controlling units which use screw compressors:w Dual circuits

w Air cooled and water cooled chillers

w Non reversible heat machines

PRO-DIALOG controls compressors and loaders needed to maintain the desired leaving or entering watercontrol point. It automatically sets the position of the electronic expansion valve to maintain a correct refrigerantflow in the cooler. For air cooled units it controls the operation of the fans to maintain the correct condensingpressure in each circuit.

Safety circuits in the unit are constantly monitored by PRO-DIALOG to ensure its safe operation. PRO-DIALOGalso gives access to a Quick Test program covering all inputs and outputs excepted compressors outputs.

The control features of the 30GX&HX Pro-Dialog Plus are divided into standard features and options (additional board needed):

3.2 - Pressure sensors

They are used to measure in each circuit :

w Discharge gas pressure

w Suction pressure

w Economizer pressure

and in each compressor :

w Oil pressure

w Economizer pressure on first compressor and also in the second compressor if unit is not equippedwith economizer

They are electronic sensors which linearise the output signal and deliver a 0 to 5 Vdc to either the basic board orto an analog board. Three types of sensors are used.

3.2.1 - High pressure side sensors

They are used to measure discharge pressure and oil pressures when large band oil pressure transducer is notselected. Carrier part: OP12DA039

High pressure side transducer curve

3.2.2 - Large band pressure sensors

They are used to measure oil pressures for unit operating with low ambient (when large band oil pressuretransducer is selected). Carrier part: OP12DA057

3.2.3 - Suction Pressure and Economizer Pressure sensors

These are in the low pressure side. Suction pressure transducer takes the place of the low pressure switches,low pressure gauges and the low pressure safety switch (where these are usually fitted). Economizer pressure isused to measure the intermediary pressure between low and high pressure. The oil pressure is subtracted fromthis pressure to determine the oil differential pressure for oil pressure safety purpose.

Carrier part: OP12DA040

Low pressure transducer curve

3.3 - THERMISTORS

All thermistor, excepted the reset sensor, have similar characteristics (see next page). They have Carrier Part No. HH 79 NZ 047

3.3.1 - Discharge gas temperature

This is installed on the discharge pipe of each compressor. It is used to control the discharge superheat. Thedischarge gas temperature (lowest discharge compressor temperature or average discharge temperature of bothcompressors) is subtracted to the saturated condensing temperature to determine the discharge superheat.

Parameters from 1 to 16 in version 1.x are the same than those in the new version 2.X.

For Retrofit from verson 1.x to the new 2.x, it is better to write down in a paper, configuration items from 1 to 16. Use Service Tool to upload all the configuration from version 1 (example address 1).Then use address search function to change the address to 2 before downloading the new softwareversion 2.x. Use Service Tool to add a new controller with a different addresse (example address 1 forversion 1 and address 2 for version 2). Once Upload configuration is done, fill factory configuration inFACTORY table and then download this.

1. 1 = air cooled. 2 = water cooled . 3 = heat machine2. 0 = no fan

< 4 = each DO output of the 4xDO board support 1 fan . > 5 = DO # 1 and DO # 2 support 1 fan each. DO # 3 support 2 fans DO # 4 support 1 fan if circuit has 5 fans max

DO # 4 support 2 fans if circuit has 6 fans max DO # 4 support 3 fans if circuit has 7 fans max DO # 4 support 4 fans if circuit has 8 fans max

nb : these fans are not controlled by a varifan. For pro_dialog 4 Auxiliary board select, each DO output of the Auxiliary board support 1 fan





13. Yes = Use Pro_dialog 4 auxiliary boards instead of old 4xAO-2xAO board and 4xDO boardNo = Use old 4xAO-2xAO board & 4x DO board (shall be set to no for version 1 retrofit)

3. When this item is selected, both compressor use the common economizer transducer in the economizer.Otherwise, each compressor uses it own economizer transducer, located in the refrigerant injection pipeline, near the motor cooling valve. Economizer pressure represents the intermediary pressure betweenhigh pressure and low pressure. It is used to determine the oil differential pressure (oil pressure -economizer pressure).

4. The use of large band oil pressure transducer is required for low ambient application and is only applied onoil pressure transducers since high pressure range transducer can not read pressure lower than 2.4 bars,Calibration is automatically determined each time the control is in OFF mode and both suction anddischarge pressures are equalized. Differences between oil pressures and suction pressure are thenstored as offset (if less than 0.4 bar).

5. MTA configuration is required for capacity calculation, motor current measurement and protection. Thisvalue shall match the one read from MTA header configuration on screw compressor board, if not an alarmwill be generated.

6. If only reclaim sensor is selected and reclaim option is not, an 4xAI-2xAO board is required, and reclaimtemperature sensor are used for information only.

7. Reclaim option requires an Aquasnap Basic board for reclaim entering and leaving temperatures,solenoids, an analogue output to control the reclaim condenser water valve, 2 transducers for reclaimpumpdown injection pressure.

8. This items indicates the number of pass the cooler fluid goes through the cooler. For example, if coolerenters from circuit A and goes out by circuit A and only 1 time, then a number of 2 shall be entered. Thisitem is used for exv control when caculating cooler pinch.

9. This items indicates if cooler leaving temperature sensor is in the circuit A or not. If cooler leaving pipe lineis on side A, then Yes shall be entered, otherwise, no shall be required. This item is used for exv controlwhen caculating cooler pinch.

10. Cooler heater option requires an Aquasnap Basic board for refrigerant isolation solenoids and heateroutput.

11. Factory password is required when accessing the main interface factory menu. Factory password can beused to access to service and user configuration sub menus.

12. 1500 = For Muller valve, Unipolar, 1500 steps, 33 steps/s (1500 steps shall be kept !!!)15000 = For Muller valve phase 3, Bipolar, 15300 steps, 300 steps/s (for future use,)

Note: this table canl be downloadable at any time. However, modified value shall not be used by tasks until theunit is in off state . This shall not apply to the Varifan/water valves gains that shall be modified at any time andused immediately by the head pressure control tasks even if the unit is in operation.

1. > 1 = Water2 = Brine3 = Low Brine

Warning: This decision affects the freeze protection threshold.w water: 1.1°Cw brine & low brine: coldest setpoint - 4.4°C

2. Used to set fan cycling. Decreasing this value will increase fan cycling. This timer can be reduced since theunit is fitted with an important number of fan stages, as to increase the condensing control accuracy. But incertain cases, notably on units with few fan stages, at too small value can causes superheat huntingproblems.

3. Used to set fan cycling. Default value is 5 ^C, 11.1^C or higher value are recommanded if unit has varifan.This value can be increased on units with few fan stages to avoid superheat hunting problems.





4. This configuration applies to varifan or water valve upon unit type. It is used to adjust the head pressurecontrol PID loop. Normally this decision has not to be modified for Varifan. For water valve it can beadjusted upon water valve type and installation.

5. Upon the operating capacity, the discharge superheat is adjusted as follows : discharge superheat control point = setpoint + 3.8^C (7^F) if no loader ON.discharge superheat control point =setpoint + 1.7^C (3^F) if one loader ON.discharge superheat control point =setpoint if both loaders ON.

6. This setpoint is used by the EXV control in order to maintain an optimal cooIer exchange delta temperaturebetween leaving temperature and saturated suction temperature. This is done in compensation withdischarge superheat temperature which has higher priority.

7. This decision allows to set the high pressure override threshold:w If the saturated condensing temperature is greater than [the maximum condensing temperature override

threshold minus the maximum condensing temperature override differential] but less than the [maximumcondensing temperature threshold] then the capacity increase shall be inhibited.

w If the saturated condensing temperature is greater than the [maximum condensing temperature overridethreshold] then one stage capacity of the corresponding circuit shall be removed (doesn't apply to the laststage).

8. This decision allows to set the high current override threshold:w If the compressor current is greater than [the maximum current setpoint threshold minus the maximum

current override differential] but less than the [the maximum current setpoint threshold] then the capacityincrease shall be inhibited.

w If the compressor current is greater than [the maximum current setpoint threshold] then a loader of thecircuit or the compressor will be stopped.

w curr_max and curr_dif are in percent of MTA (Must Trip Amps). curr_max shall not exceed 85% as thescrew compressor board shall stop the compressor for alarm when current reaches 85% of MTA.

9. The Global chillers use compressors which have better performance at full load than at part load.Therefore the loading sequence strategy will be different from the one for flotronic II or pro-dialog 30 G & Hcontrol. When compressor is on, it will try to avoid the compressor operate at low capacity (no loader ON).If this item is enable, the control will use any stage of capacity in order to keep the exchanger leavingtemperature as closed at possible to the control point what ever the compressor performance. When thecircuit is in capacity override (compressor status LEDs in the synopsis are blinking), the control will forcethe close control capacity variable to enable until the circuit is no more in override.





10. This decision allows to set the setpoint which is used for auto Z Multiplier calculation. The Z Multipliercalculation tries to maintain, for each compressor, a maximum number of starts per hour equal to [zm_spt].Thus, decreasing the setpoint shall increase the reactivity of the auto Z Multiplier to compressors cycling.

11. The Z Multiplier parameter allows to adjust the on/off time delay between compressors staging. It doesn'taffect loaders staging. Increasing this value shall increase the on/off time delay but shall reduce theaccuracy on the leaving temperature control.

w Tthe current Z Multiplier is the result of calculation based on the number of starts of compressors.However, the maximum Z multiplier calculation will be limited to the value entered in this decision.

12. This item allows the entering fluid control. Default is leaving fluid control. Entering fluid control can be usedfor small charge.

4.2.6.5 - Master/Slave configuration table

The MST_SLV table can be accessed through the Modify Controller menu of the Network Service Tool or themain interface. This table needs to be configured if the master/slave function is used. Master/slave functionallows the Pro-Dialog unit to operate as master or a slave in a two chillers plant. See section 4.20.

Decisions description:

1. This decision allows the unit to operate as master or a slave in a two chillers master/slave. The masterchiller monitors all external commands as start/stop, demand limiting, setpoint select or reset via CCN bus.Control of the slave chiller is done through commands (start/stop, demand limit, setpoint, heat cool)emitted by the master chiller. The slave will not be allowed to operate as a slave if its CHIL_S_S,CTRL_PNT or DEM_LIM, HC_SEL variables has a force priority higher than a control force.

2. This timer is started when all conditions to start the lag chiller are satisfied. Lag chiller shall not be starteduntil this timer is elapsed. To be set in the master unit table only.

3. This decision allows to activate two chillers lead/lag balance function. It is used for master/slave chillerrunning time equalization. When this function is active, once per day or each time the master chiller isswitched from the off to the on state the control determines the lead chiller based on both chillers run hoursdelta. When the run hours delta is greater than the configured lead/lag balance delta then a changeoverwill occur and the unit with the smallest operating hours value will become the lead. This function cannotoperate if the master chiller demand limit is less than 100%. In that case, the master chiller will always bethe lead. To be set in the master unit table only.

4. This function allows to set the lead/lag balance delta used for master/slave chiller running timeequalization. Lead/lag changeover occurs when the lead/lag operating time delta overlaps the configuredbalance value and provided that master unit is not under demand limit control.

5. This decision allows to set the lead chiller pull down duration before the lag chiller starts.





4.3 - Cooler Interlock contact

A contact to check the status of a safety loop is provided (cooler flow switch and customer interlock are wiredinternally in series). Its function is to prevent the unit from starting if the contact is open while the delay at startup hasexpired. The contact must also stay closed as long as the unit is not stopped through Local, Remote or CCN control.

If the cooler pump is controlled by the pro-dialog and if the cooler contact is closed after 2 minutes the cooler pumpis turned OFF provided that the contact is failed CLOSED, the alarm 75 shall be active and the unit can't no morestart until manual reset.

4.4 - Cooler heater control

This function is applied only for air cooled units and is related to the cooler pump function when the unit state is OFFor when unit operates as a lag chiller in master/slave operation and in standby mode. This is provided on outdoorunit as a safeguard against the cooler freezing. The cooler heater is associated with refrigerant isolation solenoids,one output per circuit whose goal is to prevent the refrigerant from migrating into the condenser when chiller isstopped.

The following logic shall be used:

w If the outdoor air temperature is below the cooler heater trip point and if either the saturated suction temperatureof circuit A or saturated suction temperature of circuit B are lower than the cooler heater trip point plus 3.3 ^C,the cooler heater shall be activated.

w Normally the isolation valves shall prevent refrigerant in the cooler from migrating into the condenser. For thiscase, cooler heater can ensure cooler protection efficiently without the need of using cooler pump.

w If it is not the case (SST remain low), the pump shall be turned on every 7 minutes to check freezing conditionsand additional heat to the cooler : cooler fluid temp (< 3° - [SSTa + SSTb]/2). Pump shall be turned of if coolerfluid temp > (8°C - [SSTa + SSTb]/2).

w If both saturated suction temperatures of circuit A and circuit B are greater than the cooler heater trip point plus5.5 ^C, the cooler heater shall be turned off. The pump shall be allowed to stop.

heater trip point = freeze + heat_spt (heat_sp from SERVICE2 table)freeze = 1.1 for water, coldest setpoint - 4.4^C for brine

4.5 - Oil heater control

Each circuit has its own oil separator fitted with an oil heater. Both circuit oil heater are controlled independently .Since there is no oil temperature sensor, the oil heater will be controlled based on the saturated condensingtemperature as follows :

wOil heater ON when outside temperature is below 17°C.wOil heater OFF when outside temperature is above 25°CwOil heater OFF when circuit is in operation or oil level is low (oil_sw is OPEN).

4.6 - Motor Cooling Control without plate exchanger economizer

The screw compressor motors used in the Global Chiller control are refrigerant cooled. The control strategy for motorcooling relies on vapor at light loads, and supplementary liquid refrigerant at high loads. Each compressor will haveits own cooling solenoid. An additional motor cooling solenoid is required when operating in high condensingtemperature. It is automatically controlled by pro-dialog even if it is not mounted in the units. The motor coolingsolenoids shall be cycled to allow liquid to cool the motor. The main motor cooling solenoid control is based on themotor temperature and its setpoint (83°C) using a quasi-fuzzy logic. The additional motor cooling solenoid control isjust based on the discharge gas temperature.



Rev: OriginalPage: 36/98


4.7 - Motor Cooling Control with sub cooling plate exchanger

The sub cooling plate exchanger replaces the old economizer for simple maintenance and cost reduction. Thus thescrew compressor motors are cooled by refrigerant from the plate exchanger, located between condenser and exv(see scheme below). The refrigerant flow through this exchanger for motor cooling purpose is controlled by athermal expansion valve. The opening of this valve is done by heating its internal resistor via 24 vac ouput signalfrom the screw compressor board, channel 13. For circuit which has 2 compressors, an additional solenoid (seescheme below, x=a for circuit A, x=b for circuit B) shall be controlled to balance motor temperatures. These solenoidoutput are located at channel 14 of the screw compressor board.

4.7.1 Motor Cooling Control with TQ feedback Signal Control

(refer to factory configuration and wiring for retrofit, pages, 21, 23 and 24)

Tq valve opening position depends on the heat (resistor is the image) on the TQ valve and also the equali-sation pressure located at plate exchanger (in our application, quite the same than economiser pressure).

With the same economiser pressure, the higher heating signal is commanded (CPA1_PUL, orCPB1_PUL), the lower is the resistor and the more the valve is opened.

With same heating signal value, if the economiser pressure increases, the valve will tend to close. Andvice versa

Based on this relation, if the feedback signal is enabled, the control will check all the time the relation TQposition = F (economiser pressure/TQ resistor) and shall make a kind of override (absolutely required atthe start-up, resistor is very high)When a value of 200 is sent on CPA1_PUL or CPB1_PUL (hardware SIO variable) some time, that meansresistor value is a little above the minimum position, preheat is sent.This value is sent also when loading capacity.

When the economiser pressure is steady, and TQ resistor is near to the pre-opening position, regularcontrol (PID) is used.

TQ resistor sensor is connected to the EXV board. The value read is in K Ohms MTQ_RESA (for circuitA), MTQ_RESB (for circuit B). During regular operation, value read shall be from 0.7 k Ohm to 4 kOhms.





4.8 - CAPACITY CONTROL

This function adjusts the number of active compressors and loaders to keep the leaving water temperature at thesetpoint. The precision with which this is achieved depends upon the capacity of the water loop, the water flowrate, the load and the number of capacity control steps available. The control continuously takes account of thetemperature error with respect to the control point, the rate of change of the leaving fluid temperature and the deltaof temperatures between the entering and leaving fluid in order to determine the optimum time to add or subtractsteps of capacity.

Note: a too important number of starts of a particular compressor will automatically cause a limitation of thecompressors starts. This will affect the precision of the water loop temperature control.

4.8.1 - Logic description

4.8.1.1 - Basic logic

To operate the capacity control task uses the following inputs:w EWT Entering water temperaturew LWT Leaving water temperaturew CTRL_PNT Control pointw Cooling z_multiplier Z Multiplier (range: 1.0 to 6.0)w Heating z_multiplier Z Multiplier (range: 1.0 to 6.0)

The control calculates the SMZ: load/unload factor. It is compared to the z_multiplier to determine when to add orremove stage:

w If (sum/z) > +z_multiplier -> stage = +1 (add a compressor)w If (sum/z) > +0.6 and if a loader is available (loader is OFF) -> stage = +1 (add a loader)w If (sum/z) < - z_multiplier -> stage = -1 (remove one compressor)w If sum/z) < -0.6 and loader is avaialble (loader is ON) -> stage = -1 (turn off one loader)

Note: z_multiplier doesn't apply to loaders.

4.8.1.2 - Z Multiplier calculation

The z_multiplier factor allows to indirectly increase the compressor on/off time delay. In consequence, it can beadjusted (increased) to avoid compressors short cycling. This function requires the following Service configuration:

vAuto Z Multiplier sepoint (zm_spt). Default to 6.vCooling and heating Z Multiplier max value (hc_zm). default to 6.0.

This function adapts the z_multiplier to the unit compressor cycles number (the cycle number shall be based onthe compressor which has been the most started during an hour). The significant period for compressors cyclingshall be of one hour.

If the cycle counter exceeds the setpoint (zm_spt), then the z_multiplier value shall be increased based on thecycle number (PID loop). The function shall not take care of the loaders cycling.

The calculated value of the z_multiplier shall not exceed the configured hc_zm. If the unit returns to normal operating condition with a cycles counter going down then the calculated z_multipliershall progressively return to its normal value (zm = 1.0). The rate at which the calculated z_multiplier returns tonormal shall be lower than the rate at which it is increased.

The setpoint value shall allow to adapt the auto z multiplier calculation to the installation. The setpoint rangesfrom 4 to 6.

During normal operation, each modification of the unit capacity is followed by a dead time when no capacitymodification is possible. The duration of this dead time is 90 seconds.

4.8.1.3 - Overrides





sum/z ratio will be overridden if any one of the following conditions is satisfied.

1 Cooler freeze protection2,3 Very Low saturated suction temperature4 Low source temperature protection5,6 Low discharge superheat temperature7, 8 Low temperature Cooling/High temperature heating9 Demand limit10 Cooler Lock11 Slow change override12 Ramp loading13 Minimum ON/OFF delay14 High temperature cooling and low temperature heating15 System Manager control16, 17 High pressure18,19 High current20, 21 Low saturated suction temperature22,23,24,25 High condensing temperature28 Compressor startup with loader 1 on due to low condensing temperature26, 27 Low Oil Level when circuit is OFF29,30 Stopping circuit due to low oil level (allowed thrice within 2 hours) before going to alarm31,32 High motor temperature on economizer units (T° > 93°C) 33,34 Stopping compressor due high motor temperature (T° > 110°C, allowed thrice within 2 hours)

Note : When overrides 2,3 , 5, 6, 16, 17, 18, 19, 20, 21 are active, the variable close control (cls_ctrl) shall beenabled whatever the configuration to allow unloading the last loader in the circuit.

Chiller Current Override (override #35)

This function allows customer to limit the total current (it does not include current of fans, valves, heaters, oil pumps...) of all the compressors during operation. The chiller current limit can be modified through USER configuration(USER table or User configuration by main interface). This function is similar to demand limit function.

wIf the chiller current is greater than the chiller current limit , then a stage of capacity will be removed.wIf chiller current plus the added current of selected compressor is greater than the chiller current limit, the

increase of capacity will not be allowed. If the compressors is OFF, its added current is 80% of its MTA. If theselected compressor is on but deos not reach 100% capacity, an added stage on the same compressor will add40% of its current.





4.9 - COMPRESSORS & LOADERS LOADING SEQUENCE

4.9.1 - General Description

The Global chillers uses compressors which have better performance at full load than at part load. Therefore, theloading sequence strategy will be different than for the flotronic II or for the Pro-dialog 30 G & H. The following list applies only to capacity control. For High Ambient Unloading, it can be overridden.

1. A compressor will not be started until all other running compressors are 100% loaded.

2. On units with 3 compressors, both circuits cannot have their loaders off at the same time once 3 ormore of the compressors in the unit are on. Where possible, the circuit which is starting acompressor will be the one which is to be unloaded.

3. Any time a lag compressor in a circuit is starting, the loaders in the circuit shall be turned off(unloading all compressors in the circuit). This shall be done 15 seconds prior to starting the newcompressor. 15 seconds after the new compressor has started, the loaders shall be set to theirdesired state. When a lead compressor is starting, all loaders shall be turned off when thecompressor relay is turned on (+/- 2 seconds), and shall be set to their desired state 15 secondsafter the compressor has been started.

4. There shall be a configuration decision for "close control", which (when selected) will cause thecontrol to utilize all of the loading devices to achieve better leaving water temperature control.

5. Whenever any compressor in a circuit is going to be stopped normally, the circuit shall be fullyunloaded for 15 seconds prior to shutting down the compressor. This shall not apply when thereason for a shutdown is due to an alarm condition.

7. For any shutdown, all compressors and loaders will be shut down at the same time.

For more than 2 compressors, two types of sequencing are available and configurable by the user through either theMain Interface or through the CCN network:

w Equal circuit loading: The control shall attempt to maintain equal capacity between the circuits as the machineloads and unloads.

w Staged circuit loading: The control shall load the lead circuit completely before the lag circuit is started. Whenthe load is decreasing the lag circuit shall be unloaded first.

Circuit compressors sequence select shall try to equalize the compressor starts number. That means anycompressor in the circuit can become the lead compressor if it has the lowest starts number, however, this shall bebalanced with the operating hours.

Loaders in the same circuit are commanded simultaneously. Thus one loader variable is displayed.

When a circuit is overridden (compressor status are blinking in the synopsis) because of low suctiontemperature, low or high discharge temperature or high condensing temperature (high pressure), or highcurrent then no capacity increase shall be allowed on the affected circuit. This circuit is selected to unloadcapacity first when unloading capacity condition is required.

4.9.2- Compressor capacity determination

Each compressor has three stages capacity. Simulation had been done to determine the average capacitycorresponding to those stages as following :

No loader ON -> 40%Only loader_1 -> 70%Both loaders ON -> = 100%

4.10 - EXV CONTROL

4.10.1 - General

The EXV is controlled to maintain minimum pinch for insuring the cooler exchange performance through the deltatemperature between the cooler fluid and the saturated suction temperature. EXV opening movement will normallydecrease the cooler pinch and thus increase the cooler exchange performance. But it shall not open too muchprovided a drop in discharge superheat , low oil pressure and refrigerant flow.

The EXV control shall deal with two goals : Smaller Cooler Pinch and Discharge Superheat Protection.

Additional protection against excessive EXV opening is applied to ensure the condenser heat transfer (sub cooling).It may happen when operating in high condensing temperature and indirectly high discharge superheat, exv wouldtend to open continuously to get the lower pinch due to the setpoint and unfortunately in certain conditions, this valuehas reached the limit, though it is higher than the setpoint. Therefore, EXV position limit shall be set when there isno more variation in cooler pinch for a variation of EXV position of 4 percent.

EXV position shall also be limited to avoid hunting problem due to low discharge superheat protection. It may occurwhen operating in a low condensing temperature, the discharge superheat protection can switch from enable todisable in few scans and so on.

This control uses a kind of auto adaptive method whose goal is to find out the optimal position of EXV for insuring anoptimal pinch with a correct discharge superheat and sub cooling.

4.11 - Air Cooled Condensing Pressure Control

Head pressure differential value and head pressure differential timer can be adjusted in the Service menu.Decreasing these values will increase fan cycling. This differential value and timer can be reduced since the unit isfitted with an important number of fan stages, as to increase the condensing control accuracy. But in certain cases,notably on units with few fan stages, at too small value can causes superheat hunting problems.Varifan PID gains can be modified in the Service menu (not recommended). See section 4.2.3.

SCT control point without varifan

To avoid fan cycles and also to ensure a minimum expected SCT for oil pressure, SCT control shall beadjusted based on OAT, the same for SCT differential as

4.13 - Water Cooled Condensing Pressure Control

The control of a common water valve for both circuits is required. The water valve control will be based on thehighest saturated condensing temperature of both circuit or based on the operating circuit if the other is OFF.

Water valve PID gains can be modified in the Service menu (when unit is OFF). See section 4.2.3. They areaccessible though the table SERVICE1 and can be modified during operation.





4.14 - High Pressure (Maximum Condensing Temperature) Override

This function shall be used to avoid circuit high pressure trip while the condensing pressure reaches a configurableoverride threshold (Service 1 Configuration).

wIf the saturated condensing temperature is greater than the maximum condensing temperature (mct_sp) minusthe maximum condensing temperature override differential (mct_diff) but less than the maximum condensingtemperature (mct_sp) then the circuit capacity increase shall be inhibited.

wIf the saturated condensing temperature is greater than the maximum condensing temperature (mct_sp) then thecircuit capacity shall be reduced. The first capacity stage shall never be turned off even if that causes a circuithigh pressure trip.

wIf the circuit capacity has been reduced due to high condensing temperature override then the circuit capacityincrease will not be allowed for 5 minutes even if the saturated condensing temperature is below the maximumcondensing temperature (mct_sp) minus the maximum condensing temperature override differential. This shallavoid compressor cycling.

4.15 - High Current Override

This function shall be used to avoid circuit high current trip while the motor current reaches a configurable overridethreshold (Service 1 Configuration).

wIf the current is greater than the maximum current threshold (curr_max) minus the maximum current overridedifferential (curr_diff) but less than the maximum current threshold (curr_max) then the circuit capacity increaseshall be inhibited.

wIf the current is greater than the maximum current threshold (curr_max) then the circuit capacity shall be reducedby removing a loader or the affected compressor.

wIf the circuit capacity has been reduced due to current override then the circuit capacity increase will not beallowed for 5 minutes what ever current measured. This shall avoid compressor cycling.

4.16 - Stopping Function

4.16.1- Stopping a compressor by capacity unloading

If the selected compressor is operating with at least one loader ON, then all the loaders in the same circuit shall bede-energized for 15 seconds before stopping the compressor.

4.16.2- Stopping the unit by manual command (OFF)

Both circuit shall decrease its capacity progressively every 15 seconds. One loader is immediately de-energized. Thelast loader will be de-energized in 15 seconds later. Then all compressors, oil solenoids and oil pump will bede-energized in 15 seconds after the last loader is turned OFF.Here is an example of the stopping function with time indicator for a circuit with both loaders ON before receiving aSTOP command. t = t0 loader_2 = OFF t = t0 + 15s loader_1 = OFF, t = t0 + 30s All the compressors, oil solenoids and oil pumps shall be de-energized

The exv shall be closed in one minute after the last compressor is de-energized or after the difference between discharge and suction pressure is lower than 58 psi

note : Both circuits can be stopped in different timing depending on the status of their loaders when theSTOP command is received. Maximum duration for stopping the unit is 30 seconds. A circuit can be stoppedimmediately if no loader is ON before going to stopping procedure.

4.16.3- Stopping a circuit by failure

If the circuit or the hole unit are failed by alarms freeze, low sst, cooler flow, all the compressors are shut offimmediately. Otherwise, it shall respect procedure above.





4.17- Oil pressure control

4.17.1- Oil pressure Setpoint determination

The following algorithm applies to all unit types:

104 86 70 Oil setpoint 1(kpa)> 350240 < AND <350< 240Suction pressure (kpa)

Oil Setpoint2 is calculated as follows:

0.63645* (DP - SP) + 35 2* (DP - SP) - 1516 0.235* (DP - SP) + 4Oil setpoint 2(kpa)> 1137861 < AND < 1137< 861DP - SP (kpa)

* DP = Discharge Pressure* SP = Suction pressure

4.17.2- Oil pump control

The oil pump is generally used to provide pre-lubrification of the compressor. Moreover, it is controlled to insure acorrect oil pressure during capacity transition or during operation with low condensing temperature that cause a dropof oil pressure to avoid tripping in alarm.

Thus the oil pump is turned ON when the Differential Oil Pressure is lower than Oil Setpoint 1 plus 13 kpa. and remained ON until Differential Oil Pressure is greater than Oil Setpoint 1 plus 35 kpa AND difference betweendischarge and economizer pressure is greater than Oil Setpoint 1 plus 150 kpa to avoid oil pump cycles.

ALARM 68 for Compressor A1, ALARM 69 for Compressor A2, ALARM 70 for Compressor B1, ALARM 71 forCompressor B2.

Criteria For Trip Tested only when the compressor is ON.

DOP: Differential Oil Pressure for the appropriate compressor. DOP = Oil pressure - Economizer pressure.

Economizer pressure is the common (econ_sel = YES) Economizer Pressure transducer reading for thecircuit involved or the appropriate economizer pressure transducer (econ_sel = NO) associated to thecompressor.

A. Compressor has started with Normal Ambient (oat > 10 °C) or or condenser temperature (temp > 18°C)

1. If the compressor has been running for less than 5 seconds then ignore the alarm.

2. If the compressor has been running for more than 5 seconds but less than 30 seconds andDOP < (Oil Setpoint1/30)*(Comp. Running Time [in seconds])for 3 continuous readings, then the alarm shall be tripped.

3. If the compressor has been running for 30 seconds or more, then if:a). DOP < Oil pressure setpoint1 for 15 continuous seconds,

ORb). (Poil - Psuction) < Oil pressure setpoint2 for 15 continuous seconds,then the alarm shall be tripped

B. Compressor has started with Low Ambient (oat < 10 °C) or low condenser temperature (temp < 18°C)

1. If the compressor has been running for less than 90 seconds then ignore the alarm.





2. If the compressor has been running for more than 90 seconds but less than 180 seconds andDOP < (Oil Setpoint1/90)*(Comp. Running Time [in seconds] - 90)for 3 continuous readings, then the alarm shall be tripped.

3. If the compressor has been running for 180 seconds or more, then if:a). DOP < Oil pressure setpoint1 for 15 continuous seconds,

ORb). (Poil - Psuction) < Oil pressure setpoint2 for 15 continuous seconds,then the alarm shall be tripped.

4.18 - Reclaim Operation

4.18.1 - General Description

This function shall control the air cooled to reclaim or the reclaim to air cooled changeover process.

Reclaim changeover shall be caused either by:w A manual reclaim select change due to a local, remote or CCN command on the unitw A heat reclaim temperature change while reclaim has been selected. This algorithm monitors the entering

reclaim sensor temperature and compares it with the reclaim setpoint to determine if the reclaim can be activeor not.

If the reclaim function has been selected, the reclaim shall become active when the entering reclaim temperaturecomes below the reclaim setpoint minus the reclaim deadband and delay between the last air cooled to reclaimsession is elapsed. It shall become inactive when the entering reclaim temperature comes over the reclaim setpointplus the reclaim deadband.

Non-reclaim to reclaim Changeover shall follow this procedure:

w Turn on the reclaim condenser pumpw Verify the condenser flow is established, if not after 1 minute delay has elapsed, reclaim operation shall be

aborted and an alarm shall be displayed.w Wait for 3 minutes after condenser pump is ON and until the saturated condensing temperature reaches (30

deg C) and superheat is greater than 8.6 ^Cw If saturated condensing temperature is greater than reclaim setpoint + 3.3^F, go to reclaim operation directly (it

is not necessary to make an pumpdown) otherwise, go through pumpdown (see below)w Start the pumpdown sequence : reclaim discharge valve shall be closed and reclaim pumpdown injection valve

shall be open.w Close EXV 6.67 or 3.33% upon the number of compressors on circuit every 10 seconds while pumpdown

pressure is greater than 300 kpa (44 psi), during first minute if EXV is less than 15 % opened. w After a 10 minutes duration or as soon as pumpdown pressure is lower than 300 kpa (44 psi), reclaim injection

valve shall be closed, reclaim operation is effective. Open EXV 13.33% as avoid low saturated suction alarm.w When reclaim operation is active, each circuit fan staging has its own saturated condensing control point

determined as follows:sct_ctrl_x = (hr_ewt + hr_lwt)/ 2 + rsp_x_a * capacity_x + rsp_x_b (x for circuit), rsp_x_a and rsp_x_b areservice parameters in table SERVICE2.

w Pumpdown shall not be necessary if saturated condensing temperature is greater than reclaim setpoint + 6 ^C

Reclaim to non-reclaim Changeover shall follow this procedure:w Turn off the condenser pump. w Close the reclaim pumpdown valve. w Open the reclaim discharge valve if at least a compressor is ON. Otherwise, Close it.

During reclaim operation, if the pumpdown pressure is greater than 400 kpa (59 psi), the pumpdown procedure innon_reclaim to reclaim session shall be initiated. When the number of these abnormal sessions exceeds 2 times,the reclaim operation shall be aborted, the circuit shall return to air cooled mode and an alarm shall be displayed.

At power up or after reset or after the unit capacity goes down to 0%, the function shall return to air cooled mode.

4.18.2 - Reclaim To Air Cooled Changeover Initiation

This shall determine whether the unit shall return to air cooled mode. This can be caused by the following:

Cause #1: Reclaim operation active and reclaim select is no more active

Cause #2: Reclaim mode is active and the entering reclaim temperature is above the range of the reclaimsetpoint + the reclaim dead band divided by 2 : HR_EWT >rsp + hr_deadb/2

Cause #3: Number of consecutive reclaim pumpdown sessions exceeds 2 times

Cause #4: entering reclaim temperature sensor failure





4.18.3 - Air Cooled To Reclaim Changeover Initiation

A non-reclaim to reclaim injection session has been required and at least one compressor is on and the unit is notfailed and the entering reclaim temperature is not failed and this one is below the reclaim setpoint - half of configuredreclaim deadband and delay between the last reclaim injection has elapsed.

4.18.4 - Reclaim Operation status hr_status Description

Information on reclaim operation is available on table RECLAIM (hrstatus) or on INFORMATION menu (hr_status).hr_status parameter shall contain reclaim operation indicator of both circuit in two digits, one digit per circuit (left digitfor circuit A, the other for circuit B) with the following description :

Reclaim failed due to flow switch 5

Reclaim pumpdown failed 4

Reclaim operation active3

Reclaim pumpdown mode2

Reclaim mode request 1

Air cooled operation0

Status descriptionreclaim operationindicator

*note : in case of reclaim operation failure (alarm # 83 for circuit A, alarm # 84 for circuit B), hr_status will not beinitialized until the manual reset on main interface is done.

4.18.5 - Reclaim Operation Using Air Cooled Exchanger

To avoid high pressure problem, the remained condenser (hr_val_x) can be turned ON if SCT is above reclaimsetpoint + 8.3 deg C and all fans are ON provided that fans staging is not enough to avoid the risk of exceeding highpressure override threshold. When turning ON, the remained condenser (hr_val_a) is kept to ON for at least 3minutes to let fans staging to be stabilized. This condenser can be turned OFF if it has been ON for more than 3minutes and if saturated condensing temperature is below the reclaim setpoint (rsp) to ensure the reclaim operationperformance.

4.18.6 - Reclaim Condenser Water Valve Control

if unit is not in reclaim operation, then the reclaim condenser water valve remains in minimum position.

In reclaim operation : wIf reclaim entering temperature is below 20 deg C, then reclaim condenser valve is at minimum position.wIf reclaim entering temperature is above 40 deg C, then reclaim condenser valve is at maximum position.wIf entering temperature is within the range 20 degC and 40 deg C, then reclaim condenser water valve positionwill be an interpolation between minimum and maximum position.

4.18.7 - Reclaim Condenser Heater Control

Reclaim condenser heater is ON when entering or leaving fluid are lower than 3.0 deg C( 37.4 degF). It is turnedOFF when both temperatures are above 4.4 deg C (40.0 deg F).





4.19 - Two Units Master/Slave Control

4.19.1 - General

This function allows to perform master/slave plant control between two chillers linked by the CCN network. Masterand slave chiller need to operate on the same bus. Master/slave operations shall operate in cooling or heating mode.

To operate properly, the master and the slave chillers must have an additional CHWS sensor located on thecommon chilled leaving piping when the water control is done on the outlet side. This CHWS sensor shall beconnected on each chiller basic board. When the water system control is done on the inlet side no additional CHWSsensor is required.

Parallel chiller control with dedicated pumps is recommended. Chiller must start and stop its own water pumplocated on its own piping. If pumps are not dedicated for each chiller pimping, chiller isolation valves are required:each chiller must open and close its own isolation valve through the control (valve shall be connected to the pumpoutputs).

Water system control with no individual chiller pump control is feasible. It is not recommended when the system loadis low or if the control point is close from the freeze water tripping point (because of system instability that can becaused by the freeze protection override). System flow is constant even if the master or the slave chiller is stopped.In that case, the system pump shall be controlled by the master chiller.

Series chillers with dedicated primary pumping and constant flow shall be feasible but not recommended. Pumpstart/stop must be controlled externally. Each series chiller must control its own isolation and bypass valves: stoppedchiller must be isolated from water flow (chiller pump command shall be used for valves control. Each chiller mustopen and close its own chilled isolation valve).

The master chiller shall monitor all external commands as start/stop, demand limiting or setpoint select. It needs tobe started in Master operating type. The slave chiller must operate in CCN mode. If the master chiller is turned offwhile the master/slave function is active then, the slave chiller shall be stopped.

The master/slave linkage shall not be allowed to operate if any one of the slave chiller CTRL_PNT, DEM_LIM,LAG_LIM, CTRL_PNT HC_SEL or LCW_STPT variables has a force priority higher than a control force. In that case,the master slave operations shall not be allowed or shall be disabled.

The control of the slave chiller shall be done through commands emitted by the master chiller. The slave chiller hasno action in the master/slave operations: it shall only verify that CCN communication with its master is correct.

The master function shall provide the ability to select a lead chiller among the master and the slave. Selection shallbe based on the delta between the master and the slave run hours and shall try to optimize the runtime hours. If thisfunction is unused then, the lead chiller shall always the master. Lead/lag changeover between the master and theslave due to hour balance shall occur during chiller operations odd days at 12:00 a.m. or at startup.

The lead chiller shall always be started first and the lag chiller shall be maintained at zero percent capacity throughmaster forcing the lag demand limit value (LAG_LIM) to 0%. The lag water pump shall be maintained off. When thelead chiller cannot be loaded anymore (because it is loaded at its full available capacity or at the master demandlimit value) then the lag start timer is started. When the lag start timer is elapsed, if the error on the master controlledsetpoint is greater than 3^F and if the pulldown time is elapsed then, the lag chiller water pump shall be turned on (ifrequired by configuration) and the lag chiller shall be allowed to start through master forcing the lag chiller demandlimit value (LAG_LIM) to its own demand limit value. To ensure that the lag chiller will be unloaded first in case ofwater load decrease then, the lead chiller setpoint error shall be reset of upwards 4^F provided that the lag capacityis not zero.





The lead pulldown time tells how long after starting the lead chiller (one time after the master chiller status has beenmanually started) before checking whether to start an additional chiller. This time delay gives the lead chiller achance to pull down the loop temperature before starting another chiller.

If a communication failure is detected between the master and the slave then, all master/slave functions shall bedisabled and chillers shall return to standalone operations until communication is reestablished.

Note: to ensure that no compressor is started before the flow rate is correctly established then, the water flow controlis absolutely required on the lag chiller for master slave operations.

The figures below illustrate master/slave application for the most common plant layouts. Those figures are notexhaustive.

4.19.2 - Abnormal conditions

If a communication failure is detected between the master and the slave then all master/slave functions shall bedisabled and chillers shall return to standalone operations until communication is reestablished.

If any chiller is stopped due to failure then the other chiller will be allowed to start with no delay.

If master/slave configuration error occurs, master/slave shall be disable.
