USER'S MANUAL
Features Compressor The BSC Series semi hermetic screw compressors incorporated in the chillers follow state-of-the-art manufacturing processes which are ISO 9001 certified and use high precision machinery. The salient features of these compressors are:
•
Highly efficient with low noise levels
•
Tested in accordance with ARI Standards
•
Due to few moving parts such as Male and Female Screws and Slider valve, these compressors have minimal wear and tear
•
Each compressor has the latest 5 to 6 Patented Profile design, with separate Radial and Axial force Bearings, Built-in Oil Separator, PTC Motor winding protection, Discharge temperature protection with its controller, Oil level switch and Oil differential pressure switch. This guarantees reliability and long life of bearings under heavy working operating conditions.
•
Each Compressor has Step capacity control from 25% to 100%, making it suitable for part load applications and efficient under part load conditions. The capacity control also helps in limiting the starting current.
Liquid Injection The refrigerant suction gas cools the winding of the Semi hermetic Screw Compressor Motor. During part load operation where the suction gas circulation is less, as an abundant precaution, liquid refrigerant is injected to the suction side of the compressor to cool the motor winding. Liquid injection during this period keeps the motor winding temperature within limits. This is provided as a standard feature to enhance the life of the compressor.
Evaporator The shell and tube evaporator has inner grooved copper tubes for better heat transfer. The tubes are designed to optimize for refrigerant and water velocities.

•
In-built time delays for compressor single phase / phase reversal protection and anti freeze protection
•
Password protection at two levels.
Optional features in Control Centre
•
RS 485 port & TCP/ IP web gate for remote connectivity, fault indication and status facility
•
PC connectivity and remote monitoring without BMS through dedicated telephone line, Gateway and Modem.
•
BMS compatibility with JC N2, BACnet and Modbus protocol with Translator.
•
Windows based support system to provide complete status on all operations both locally and remotely. History, static and dynamic graphing to aid in commissioning, trouble shooting and evaluation. These features help in accurate operation and protection of the chiller.
Following additional features are available in Air Cooled version:
Economiser Refrigerant liquid to liquid plate type heat exchanger is provided for the economiser system. The liquid refrigerant is sub cooled to enhance the capacity thereby reducing power consumption (IKW/ TR) and enhancing the Coefficient of Performance (COP).
Oil Cooler Effective lubrication of bearing depends on the viscosity of lubricant, which in turn depends on the oil temperature. To ensure effective lubrication for longevity, oil cooler is provided as a standard option for Aircooled Application.

SCREW CHILLER (Air & Water Cooled)

USER'S MANUAL
Rigging and Installation Rigging When the chiller arrives at Warehouse/Site, proper rigging and handling is mandatory during unloading and leading the unit into position. Care must be taken to keep the unit upright during rigging. Avoid unnecessary jerking or rough handling. Proper hoisting straps should be used when rigging (nylon flat rope). It is also mandatory that an experienced and reliable rigger be selected to handling unloading and final placement of the equipment. The rigger must be advised that the unit contains internal components that require to be kept in an upright position. Care must be exercised to avoid twisting of the equipment.
Storage Check for transportation damages if any and take up with factory for any damages. In case the site is not ready to install the chiller, proper care should be taken to store the chiller in a covered space. Check up the pressure of the unit when received. If the pressure is not retained in the system, the system should be pressure tested immediately, repair the leakages if any and charge the system with Nitrogen. Never keep the system without pressure.
Installation (Aircooled) Proper care should be taken to make the foundation for the Chiller. Study the GA drawings of respective models and arrange for wider foundation as rquired to accommodate all the springs within the width of foundation since the springs centres ar enot in one straight line. In case the Chiller is located on the roof top, ensure that the same is located in such a way that the load of the same is transferred to the columns and not to the slab directly. The foundation should be properly levelled.

2. Hardware Structure The structure of the pCO1 features:
•
The pCO1 controller, fitted with a 16bit microprocessor for running the control program, and the set of terminals required for connection to the controlled devices (for example: valves, compressors, fans). The program and the parameters are saved permanently in the FLASH memory, preventing data loss in the event of power failure (without requiring a backup battery). The pCO1 also allows connection to a local pLAN network made up of a series of pCO1 boards and terminals. Each board can exchange information (any variable, digital or analogue, according to the application software) at high transmission speeds. Up to 32 units can be connected, sharing information in very short times. The connection to the supervisor/tele-maintenance serial line, based on the RS485 standard, is made using the optional serial cards (PCO1004850) and the Carel or Mod Bus communication protocol.
•
The terminal, also managed by microprocessor, fitted with display, keypad and LEDs to allow the programming of the control parameters (Set Point, differential band, alarm thresholds) and basic functions by the user (ON/OFF, display of the controlled values, optional printing).The terminal does not have to be connected to the pCO1 for normal operation, but can be used for the initial programming of the fundamental parameters.
•
The pCO1 has a variation of only on input and output configuration and available memory.
The following is a description of the pCO1 (Medium version) with reference to the basic layout:

USER'S MANUAL
Installation Power supply The pCO1 can be powered at: 22/38Vdc and 24Vac ±15%, 50 z, with a maximum power input Pmax= 13W. For alternating current power supplies, during installation use a Class II safety transformer, rated to at least 40VA and with a 24Vac output. To supply more than one pCO1 controller with the same transformer, its rated power must be n x 40VA, where n is the number of controllers supplied by the transformer, independently of the version of the controller. The power supply to the pCO1 controller/controllers and the terminal/terminals must be separated from the power supply to the other electrical devices (power contactors and other electromechanical components), inside the electrical panel. If the transformer secondary is earthed, make sure that the ground wire is connected to terminal G0.When powering a series of pCO1 boards connected in a pLAN network, make sure that the G and G0 connections are correct (G0 must be same for all the boards). The table below summaries the possible status of the power LED.

The following warnings must be respected for correct connection: •
Power supply different from that specified can seriously damage the system;
•
Use cable plugs suitable for the terminals being used. Loosen each screw and insert the cable plug, and then tighten the screws. At the end of the operation lightly tug the cables to check that they are tight;
•
Separate as much as possible the probe signal and digital input cables from the inductive load and power cables, to avoid possible electromagnetic disturbance. Never use the same channeling (including that used for the electrical cables) for the power cables and probe cables. Avoid the probe cables being installed in the immediate vicinity of power devices (contactors, circuit breakers or the like);
•
Reduce the length of the sensor cables where possible and avoid spiraling around power devices. The probe connection must be made using shielded cables (minimum cross section for each lead: 0.5 mm2);
•
Avoid touching or nearly-touching the electronic components on the boards, to avoid (extremely dangerous) electrostatic discharges from the user to the components;
•
If the power supply transformer secondary is earthed, check that the ground wire corresponds to the lead connected to terminal G0 in the controller;
•
Separate the power supply to the digital outputs from the power supply to the pCO1;
•
Do not fasten the cables to the terminals by pressing the screwdriver with excessive force, to avoid damaging the pCO1.
Connecting the analog inputs The analog inputs can be configured for the more common sensors on the market: NTC, 0/1V, 0/ 10V, 0/20mA, 4/20mA. The different types of sensors can be selected using the corresponding dipswitches, as in the following figure.

USER'S MANUAL
Connecting the digital inputs : The pCO1 features up to 14 digital inputs for connecting safety devices, alarms, device status, and remote switches. These inputs can work at 24Vac, 24Vdc and some at 230Vac.
WARNING: separate the probe signal and digital input cables as much as possible from the inductive load and power cables, to avoid possible electromagnetic disturbance 24Vac digital inputs : The following figure represents one of the more common connection diagrams for the 24Vac digital inputs.
Connecting the digital outputs : The pCO1 features up to 13 digital outputs with electromechanical relays. For ease of installation, the common terminals of some of the relays have been grouped together. If the diagram in Fig. 4.8.1.1 is used, the current at the common terminals must not exceed the rating (nominal current) of a single terminal. The relays are divided into groups, according to the degree of insulation. Inside each group, the relays have just single insulation and thus must have the same voltage (generally 24Vac or 110/230Vac). Between the groups there is double insulation and thus the groups can have different voltages.
Electromechanical relay outputs :
Fig. 4.8.1.1
Installing the user terminal : The connection between the user terminal and the pCO1 is made using a 6-way telephone cable supplied by Carel.To make the connection, simply insert the telephone connector in terminal J10 on the pCO1 and in terminal B on the user terminal. Insert the connector fully into in the terminal until it clicks into place. To remove the connector, simply press lightly on the plastic flap and remove the cable. The pCO1 can also work without the terminal; do not disconnect and then reconnect the terminal to the pCO1 without first having waited around 5 seconds (if the operation is performed with the unit on). For devices used in residential environments or similar, and thus subject to CEI EN 55014-1 -04/98, any standard terminals connected by J10 must use a shielded cable. The shield must be connected to the GND terminal of J11.
39
SCREW CHILLER (Air & Water Cooled)
The electrical connections are the following. Connect the telephone cable (code S90CONN00* from the power board (code PCO1*) into the corresponding jack. For model PCOI00PGL0 only, connect the 24Vac (30VA) power supply to the screw terminal block. If the same transformer is used for the pCO1, G and G0 must be the same on the pCO1 and the terminal.
pAN network : As already mentioned, the pCO1 controllers can be connected to the pLAN local network, allowing the communication of data and information from one location (node) to another. Each pCO1 can be connected to a Carel supervisory network, using the optional PCO1004850 cards.
The pCO1 terminals can monitor the control variables (temperature, humidity, pressure, I/O, alarms) from one or more boards. If one or more terminals are disconnected or malfunctioning, the control program continues to function correctly on each pCO1 board. Generally, the application program can monitor the status of the network and intervene as a consequence to ensure the continuity of the control functions. Figure 5.1, shows the pLAN network connection diagram: a maximum of 32 units can be connected (including I/O interface cards and user interface cards).The 32nd unit can only be a terminal. All the versions of the pCO1 can be connected in a local pLAN network without requiring additional boards (Fig. 5.1). The programs for the different applications (e.g.: standard chiller, standard air-conditioner, compressor packs, ...) can not be automatically integrated into a local network: they must be modified to consider the network strategy and structure, and then be recompiled using the Easy Tools system. All the devices connected to the pLAN network are identified by their own individual address, from 1 to 32 for the terminals and from 1 to 31 for the I/O boards. As the terminals and the pCO1 I/O boards use the same type of address, terminals and pCO1 boards cannot have the same identifier. The addresses are set for the terminals using the dipswitches on the rear. The network can be made up of any type of terminal, LED, 4x20 LCD and graphic, as well as pCO and pCO1 controllers.
40
USER'S MANUAL
Setting the pCO1 address : The pCO1 controller does not have dipswitches for setting the pLAN network address.The pLAN address is set using a standard 4x20 LCD terminal. Proceed as follows: •
Disconnect the pCO1 from the power supply;
•
Organise a standard Carel 4x20 LCD terminal with the address set to 0;
•
Connect the terminal to the pCO1;
•
Disconnect the pCO1 from any plan connections to other controllers (terminal J11);
•
Power the pCO1, pressing the UP and ALARM buttons at the same time;
•
After a few seconds the following screen will be displayed:
•
To modify the address simply use the UP and DOWN buttons, and then press ENTER to confirm.
Setting the terminal address : The address can be set in the range from 1/32 using the dipswitches 1/6 on the rear. The graphic terminal does not require the setting of the address, as this is determined by the program EPROM. Fig. 5.2.1 shows the rear view of the terminal board.
Fig. 5.2.1
Important Warning: if the application software does not envisage a pLAN local network, the dipswitches must be positioned to 0.

SCREW CHILLER (Air & Water Cooled)
5.4 pLAN Electrical Connections Connection between boards in a pLAN network is carried out using an AWG20/22 shielded cable, twisted pair plus shield. The boards are connected in parallel, with terminal J11 as the reference. Pay ATTENTION to the network polarity: RX/TX+ on one board must be connected to RX/TX+ on the other boards; the same is true for RX/TX-. Fig. 5.4.1 shows a diagram of a number of boards connected in a pLAN network and powered by the same transformer, typical for a number of boards connected inside the same electrical panel. Remote installation of the terminal in a pLAN network when pCO1 boards are connected in a pLAN network, the terminal can be remotely-installed at a distance of up to 50metres, if using a telephone-type cable, while it can be located at a distance of up to 200metres if using an AWG shielded cable. The following figures show the connection diagrams for the various configurations. Remote installation of the terminal in a pLAN network using a telephone cable. This type of remote installation requires the insertion of two ferrites, code 0907858AXX, at the markings with the letter F in Fig. 5.5.1.1. Figs. 5.5.1.2a and 5.5.1.2b show respectively the ferrites to be installed the open and closed position. The ferrites are mounted on the telephone connection cable, one on the pCO1 side (see Fig.5.5.1.3) and the other on the terminal side (see Fig. 5.5.1.4). Note: The graphic terminal, unlike the other LCD models, requires a 24Vac power supply from the Plug-In terminals (terminals G and G0).This may be the same line that powers the pCO1 (in this case, make sure G and G0 correspond), or alternatively may be supplied by another transformer; in this case, do not earthy the secondary.
Warning: the telephone cable must exit the pCO1 perpendicularly. Reading the 3 LEDs on the pCO1 board The pCO1 board features 3 signal LEDs (red, yellow and green) that provide information on the operation of thepCO1 board and the status of the connection to WinLoad32.

*: Cases in which pCO1 reverts to Low Level status: - When starting the pCO1 detects that Win Load is connected. - When starting the pCO1 detects “Application corrupted…”. - During normal operation the pCO1 runs a JUMP atom without the correct reference or backwards. After 20 seconds of Low Level status without Win Load connected, the pCO1 is automatically reset. •
If the pCO1 is started with the key inserted and the key switch is set to Key (see Fig. 6.1.1), (SELECTION LED red ), without pressing the buttons on the local terminal, the program resident in the key is run, without modifying the program resident in the pCO1. In practice, the pCO1 controller can run an alterative program and/or setup to the resident version. This function is useful for testing upgrades to the BIOS and/or APPLICATION, without overwriting the software resident in the pCO1. It is also very useful for running special functions or parts of programs (e.g. final functional tests) using special parameter Configurations and/or programs (expressly developed for these functions), without modifying the program resident in the pCO1.Only the program and/or parameter configuration resident in the key are modified. Once this phase is complete, switch off the pCO1 controller, remove the key, and when starting the pCO1 the next time, the original program and setup are used.
•
If, on the other hand, the key switch is set to pCO1 (SELECTION LED green) and the buttons on the local terminal are not pressed, the key has no effect.
•
To display or modify the pLAN address, use the local terminal: switch off the pCO1, remove the terminal from the pLAN network, connect the user terminal with address set to 0, start the pCO1 and hold the ALARM and UP buttons until the screen is displayed showing the pLAN address, then follow the instructions on the screen.
•
The current version of program can be checked at any time (by CRC code expressed in hexadecimal), and whether the program on the key or the resident program is used.

1. Capacity Control Method The capacity control method is based upon to develop the control zone on both side of Water leaving temperature set point, and accordingly add or subtract the capacity control stages of chiller. To accomplish this system will constantly monitor the set point, trend of load and slide position in relationship to the control zone.
1.1 Common Definitions 1.1.1 Target The control target is “Water Leaving Set point”. This will be the base of developing the control zone.
1.1.2. Control Zone The control zone is developed by adding the set points for the control target and the dead band + to obtain the upper limit. The lower limit is obtained by subtracting the dead band - set point from the control target Once the control zone has been established, the system will attempt to keep the control sensor reading with in this range. The capacity control stage calculation is in hold if the chiller running in control zone.
1.1.3. Controlling Sensor This is the sensor that has been specified as leaving temperature.
1.1.4. Trend of Load The Trend of Load is how fast the control value is changing over a period of time. If the control value is increasing the rate will be positive, if decreasing the rate will be a negative value. How fast the input is changing, its direction and where the current input reading is in relationship to the control zone will determine what action the system will take.
1.1.5. Slide Valve Countdown The system will not attempt to take action until the Slide Valve Count down reaches zero. The speed that it is decrement by is based upon the Trend of Load of control input value and the slide Response that has been specified.
1.1.6. Slide Response The purpose of the Slide Response value is to limit or dampen how fast the slide reacts to changes indicated by the control sensor. The lower the number, the faster the system will react to changes of the control sensor. The Control Status portion of the Status screen is shown below. Chiller information:

2. Capacity Control State Capacity Control States are active for all five releases of software.
UNIT IN POWER UP This state is entered when the Controller is powered up or the system has been reset. The system will remain in this state for the time specified in set point POWER UPDELAY, set point 23, or if not active for 60 seconds. In this state all points (RO’s) are turned off. This is a time delay to insure the controller has stable power before starting the algorithm.
UNIT IN LOCKOUT This state is entered whenever a critical situation is encountered that could cause harm to the chiller package. Items such as freeze protect and emergency stop will force the system into this state. Lockouts can be reset with user level authorization from the keypad; however if the lockout condition has not been corrected, the system will again be forced into the LOCKOUT state. NOTE: If the Lockout reset is pressed more than 10 times in a day the unit cannot be reset till Factory authorization.
EXPANSION BOARD OFFLINE This state will be entered whenever the controller loses communications with any of the I/O boards that are connected via the network. When this state is entered the system will generate an off line alarm, which locks out the unit. The lockout-reset key must be depressed to reset the system, after the lost I/O has been corrected.

SCREW CHILLER (Air & Water Cooled)
SWITCHED OFF This state is entered when the run stop switch is off, in the stop position. When the chiller is in this state, the individual circuit states if active are moved to the CMP IS OFF state through the normal states.
SCHEDULED OFF This state is entered when the schedule is calling for the package to be off. When the chiller is in this state, the individual circuit states if active are moved to the CMP IS OFF state through the normal states.
OFF- NO EVAP FLOW This state is entered when the evaporator flow switch is off. When the chiller is in this state, the individual circuit states if active are moved to the CMP IS OFF state through the normal states. The controller will generate the alarm in this condition and not required to be reset if alarm is clear.
UNIT IS HOLDING This state is entered when one of three conditions exists: 1. The control sensor reading is being maintained with in the control zone. 2. Control sensor reading is above the control zone but the Trend Of Load is less than the value in the set point. This indicates that the temperature is decreasing toward the target at an acceptable speed. Therefore, no additional cooling is needed at this time. 3. The temperature is below the control zone but the Trend of Load is greater than the set point. This indicates that the temperature is increasing toward the target.Therefore, no reduction in cooling is needed at this time. This state indicates that there is no need to adjust the cooling capacity of the chiller package. This state will be exited when more or less capacity is required.
3. Circuit Control States The action of the circuit control states actually result in more, less or no change in the amount of cooling capacity. The CAPACITY CONTROL STATES dictate how the individual circuits move within their states.
CMP LOCKED OUT This state is entered when the Capacity Control State is LOCK OUT or a safety set point for this circuit has indicated that a critical situation has been encountered. Set points such as LOW SUCTION, HI DISCHARGE PRESSURE etc. are examples of safety set points. Lockouts can be reset with USER level authorization from the keypad; however if the lockout condition has not been corrected, the circuit will again be forced into the LOCKOUT State.
SAFETY TRIPPED This state is entered when a safety trips but a lockout is not to be generated. An alarm is generated but the system will restart after the delay specified in the corresponding set point. If a second trip occurs within the time specified in the set point, the circuit will be placed in the CMP LOCK EDOUT State.

USER'S MANUAL
CMP OFF / READY This state is entered when no cooling capacity is required from this circuit or the prior state was CMP ANTICYCE, LOST IO LOCKED or SWITCHED OFF. In this state the circuit is ready to provide cooling capacity if needed. The circuit will remain in this state for a minimum of 60 seconds.
CMP PMP DOWN This state is entered whenever the pump down switch has been turned on or if this circuit is no longer wanted on. The compressor is on and the liquid line solenoid is closed. This state is active until the suction pressure reaches the value in the set point PMP DWN DELAY. The circuit will then move to the ANTICYC State.
CMP ANTICYCLE This state is entered when the PMP DWN State has been completed. The circuit will stay in this state with all circuit points off for the period of time contained in either set point “ANTYRECYCLE TIME “. The circuit will then move to the OFF State.
FAST UNLOADING For screw compressors, this state is entered when the compressor is turned on. The system will remain in this state for 60 seconds while the “fast unloader” and unload points are on. This is to ensure that the screw is unloaded.
CMP IS HOLDING This state only exists for infinite step compressors (Three solenoid valve SV1,SV2 & SV3 ). In this state, the required refrigeration capacity of system is being meant; no movement of the slide valve is required.
CMP IS AT 25% This state is when the compressor is providing 25% of its capacity. In this state, the relay output to activate the 25% valve is turned on.
CMP IS AT 50% This state is when the compressor is providing 50% of its capacity. In this state, the relay output to activate the 50% valve is turned on.
CMP IS AT 75% This state is when the compressor is providing 75% of its capacity. In this state, the relay output to activate the 75% valve is turned on.
CMP IS AT 100% This state is when the compressor is fully loaded. In this state, the circuit is providing the maximum amount of cooling capacity.

HI DISC UNLOAD Refer to set points HI DISCH PSI, HI DISC UNLD, HI DISC RELD7 and HI DISCH TMP, HI DISCH UNLD and HI DISCH RELD. This state is entered when a fully loaded circuit, that has more than one step, has encountered either a dangerously high discharge pressure or discharge temperature. One step of cooling capacity will be turned off. The circuit will remain in this state for a minimum of five minutes before returning to the LOADED state if the dangerous condition has been corrected. When capacity is being held due to a high discharge condition, once the discharge goes to normal operating condition the circuit will return to its appropriate state.
LO SUCT UNLOAD Refer to set points, LOW SUCTION, LO SUCT UNLD and
LO SUCT RELD.
This state is entered when a fully loaded circuit, that has more than one step, has encountered a dangerously low suction pressure. One step of cooling capacity will be turned off. The circuit will remain in this state for a minimum of five minutes before returning to the LOADED State if the dangerous condition has been corrected. When capacity is being held due to a low suction pressure condition, once the suction pressure returns to a normal operating condition the circuit will return to its appropriate state. This should be same for “LOW GAS “
LO TMP UNLOAD The circuits leaving liquid temperature have caused the system to unload. When the leaving liquid temperature gets to within 1.5 degrees F of the Freeze set point, the unload will occur before we hit the freeze protect safety.
HI AMP HOLD This state is entered when a fully loaded circuit, that has more than one step, has encountered a dangerously high AMP draw. Refer to set points for FLA per circuit and HI AMPS %. In this state, one step of cooling capacity will be turned off. The circuit will remain in this state for a minimum of five minutes before returning to the LOADED State if the dangerous condition has been corrected.
4. Condenser Control Logic 4.1 Condenser Fan Cycling Logic The air condenser set points are as follows: Set point CND STG1 ON - Condenser stage 1 cut in (ON). Set point CND STG1 OFF - Condenser stage 1 cut out (OFF). Set point CND DIFF ON - Differential between condenser stages for cut in (ON). Set point CND DIFF OFF - Differential between condenser stages for cut out (OFF). Set point CND MIN RUN - Minimum run time for a condenser stage when the discharge pressure reaches this value the first condenser point is turned on. If additional condenser points exist, they will be turned on when the pressure exceeds the previous cut in value plus the value contained in (COND DIFF IN) set point.
66
USER'S MANUAL
As the discharge pressure is reduced, the condenser points will be turned off based upon the set point (COND ST1 OFF) value plus the condenser step times the value contained in (COND DIFF OUT) set point. The first step will be turned off based upon the valve in the set point (COND ST1 OFF). Example Set point 45 CND STG1 ON = 200.0P Set point 46 CND STG1 OFF = 170.0P Set point 47 CND DIFF IN = 20.0P Set point 48 CND DIFF OFF = 5.0P COND FAN1 ON @ 200.0P DISCHARGE COND FAN 1 OFF @ 170.0 P COND FAN2 ON @ 220.0p (200.0 + 20.0) COND FAN2 OFF @ 175.0p (175.0 + 5.0) COND FAN3 ON @ 240.0p (220.0 + 20.0) COND FAN3 OFF @ 180.0p (170.0 + 10.0), etc.
5. Set Point Definitions 5.1 SET POINT TYPES: There are three different types of set points. The type determines the action that the system will take.
5.1.1. SET POINT This type of set point’s value contains a target or provides information for some type of action. The time element in this type is not used
5.1.2. LOCKOUT This type of set point’s value contains a safety level and the time that the safety must be violated before the safety will trip. Once a safety has tripped the system will take the appropriate action, shutting down the entire package or an individual circuit (compressor) depending on the purpose of the safety. The system will then wait the safety down time contained in that set point before trying to return the system to normal. If successful, the system will continue to operate. If a second trip occurs on the same set point with in the lock out delay time that is contained in that set point the system will move to a LOCKOUT state. IF THE LOCKOUT DELAY TIME IS SET TO ZERO THE LOCKOUT WILL OCCUR ON THE FIRST TRIP. This will require manual intervention to reset the system. With each safety trip, the system will generate an alarm; refer to Alarms and Safeties section of this manual.
5.1.3. ALARM This type is similar to the LOCKOUT set point except it will never cause a lock out. The system will continue to try to return to normal operation after waiting the safety down time. An ALARM set point type will never require manual intervention to reset the system.

USER'S MANUAL
6.4 Set Points for Compressor Safeties 1.
HI AMPS : This set point is a percentage of the FLA; it is used to create the high amp draw limit. This value is tested in the high amp safety, if the amps exceed this value for the time specified in this set point the safety is tripped.
2.
LOW AMPS : This set point is a percentage of the FLA; it is used to create the low amp draw limit. This value is tested in the low amp draw safety, if the amps exceed this value for the time specified in this set point the safety is tripped.
3.
LOW SUCTION : If active, the system checks for low suction pressure for each running compressor. The system will compare the suction pressure sensor reading to this value. It must be less than the value for the period of time specified in the set point before this set point will trip.
4.
LOW SUCT UNLOAD: The purpose of this set point is to take corrective action before a low suction pressure safety occurs. If a circuit has more than one step and it is fully loaded and if the suction pressure is less than the value of the safety set point (LOW SUCTION) plus the value of this set point, the system will turn off one step of capacity.. The circuit state will be changed to LO SUCT HOLD. The circuit will remain in this state for a minimum of 5 minutes. At that time, if the suction pressure has increased to a level greater then the value of set point LOW SUCTION plus the value of set point LOW SUCT RELD the compressor will return to normal control.
5.
LOW SUCT RELD: The system will force to load if requirement ,if this setpoint is satisfied
6.
UNSAFE SUCT : If active, the system checks for low suction pressure that is in an unsafe condition for each running compressor. The system will compare the suction pressure sensor reading to this value. It must be less than the value for the period of time specified in the set point before this set point will trip. Note the time period specified should be very short, 2-5 seconds. This safety set point trips the circuit to the LOCKOUT state immediately, no retry.
7.
HI DISC PSI : If active, the system checks for high discharge pressure condition for each running compressor. The system will compare the discharge pressure sensor reading to this value. It must be greater for the period of time specified in the set point before this safety will trip.
8.
HI DISC UNLOAD : The purpose of this set point is to take corrective action before a high discharge pressure safety occurs. If a circuit has more than one step and it is fully loaded and its discharge pressure exceeds the value of the safety set point HI DISCH PSI minus this set point, the system will turn off one step of capacity. A screw compressor will be forced to unload until the discharge pressure falls below the calculated value. The circuit state will be changed to HI DISC HLD. The circuit will remain in this state for a minimum of 5 minutes. At that time if the discharge pressure has dropped below the value of the HI DISCH PSI minus the HI DISC RELD the compressor will return to normal control.
9.
HI DISC RELD : This set point works same as Low Suct Reld
10. LOW DISC PSI : If active, the system checks for low discharge pressure. The system will compare the sensor reading to this value. It must be less than the value for the period of time specified in the set point before a safety trip occurs. 11. HI DISC TMP : If active, the system checks for high discharge temperature condition for each circuit that has at least one step on. The system will compare the discharge temperature sensor reading to this value. It must be greater for the period of time specified in the set point before this safety will trip.

SCREW CHILLER (Air & Water Cooled)
12. HI DISC UNLOAD : The purpose of this set point is to take corrective action before a high discharge temperature safety occurs. If a circuit has more than one step and it is fully loaded and its discharge temperature exceeds the value of the safety set point HI DISCH TMP minus this set point, the system will turn off one step of capacity. A screw compressor will be force to unload until the discharge temperature falls below the calculated value. The circuit state will be changed to HI DISC HLD. The circuit will remain in this state for a minimum of 5 minutes. At that time if the discharge temperature has dropped below the value of the HI DISCH TMP minus the HI DISC RELD the compressor will return to normal control. 13. HI DISC T RELD : This set point works same as LOW SUCT RELD 14. LOW OIL DIF : If active, the system checks for low differential oil pressure. The system will compare the calculated differential oil pressure to this value. It must be less than the value for the period of time specified in the set point before the safety will trip. 15. UNSAFE OIL : If active, the system checks for low differential oil pressure. The system will compare the calculated differential oil pressure to this value. It must be less than the value for the period of time specified in the set point before the safety will trip. The time delay for this set point should be very short 2-5 seconds. These safeties trips to a lockout no retry are attempted. Manual intervention is required. 16. HII OIL TEMP : If active, the system checks for high oil temperature. The system will compare the oil temperature sensor reading to this value. It must be ON or greater for the period of time specified in the set point before this set point will trip. The sensor can be either an analog or digital input. 17. SAFETY HOLD DELAY : Time in seconds to hold before trying to reload when the capacity has been decreased to avoid a safety, (Examples: high disc psi, high disc temp, low suct psi, etc,) 18. LEAD COMP. Enables the user to specify the lead compressor. 19. COMP. ROTATION Specifies the number of days between rotation
6.5 Set points for Unit Safeties 111 FREEZE If active, the system checks for freeze protection. The system will compare the chilled water out temperature to this value. It must be less than the value for the period of time specified in the set point before this safety will trip.
6.6 Economizer Set Points Economizer On % the set point at which Economizer will get ON Economizer Off % the set point at which Economizer will get OFF
6.7 Oil Differential Calculation The calculation is DISCHARGE PRESSURE minus SUCTION PRESSURE.
7. Authorization Function The authorization code is a special four-character code that enables access in to the system. The code must be numeric with values between 0 and 9if it is to be entered from the Keypad/Display. This provides the capability of issuing different codes to different people if desired. There are four levels of authorization, which provide different capabilities with in the system. The authorization code and the
70
USER'S MANUAL
associated level cannot be displayed in system. The authorization codes must be protected and remain confidential, if they are compromised unauthorized personnel can gain access to the system. The two level of safety has been provided 1. User level - Authorized to Change Water leaving set point within the Min & Max value, lockout reset and control zone 2. Factory Level - Authorized for rest of all the things
7.1 RESTORE FACTORY SETTING AND DATA LOGGING 7.1 .1 If some modification has been made in the program SETPOINT, the factory setting can be restored through the set point “Restore Factory Setting” at any movement. 7.1.2. Maximum 100 alarms can be stored with SP, DP and Current reading during trip. The last 20 Dynamic reading with the interval of 1 second will also get stored which will updated with the mention time interval.
8. On/Off Switches The following digital input switches can be associated with the system, their action will affect the chiller package or an individual circuit, and then action will only affect that circuit:
•
Flow switch, if off the system has lost flow. The system wills either lock out, if NO FLOW set point is active, or shut down, if NO FLOW set point is inactive.
•
Pump down switch, if on and the compressor is off, will not start the compressor. If the compressor is on, the system moves to the pump down state to begin the process of turning off the compressor(s) in normal steps.
•
Run/Stop, if off the system will not run. This is usually wired to a RUN/STOP switch that is manually positioned. If the system is running, the system moves all circuits (compressor) to off in normal steps. (If a RUN/STOP and a Network RUN/STOP are both available they operate in series.)
•
Emergency Stop switch, if on, the system will be shut down immediately and will remain disabled until the switch is off.
9. Operating Schedules Two operating schedules per each day of the week and 8 holidays are supported. Each schedule contains a start and end time, if the time and day of the system is with in these limits the schedule is true and the system will be allowed to run. If not, the system will be off due to schedule.
10. Compressor The compressor with the least number of TOTAL RUN HOURS will become the lead. Refer to Set points #103 & #104.

11. Alarms and Safeties 11.1 Introduction There are three types of alarms that are generated by the Carel control logic:
•
Information only alarms,
•
Controller system alarms and
•
Chiller set point safety alarms.
All of the alarms have the same format. The alarm is identified and it is date time stamped. Alarms can be viewed from Carel controller by pressing the ALARM STATUS (4) key or from the PC-Connect Program.
Sensor inputs used in conjunction with Controller set point safeties: 11.1.1 Suction Pressure - Pressure transducer to read the suction pressure. 11.1.2 Discharge Pressure - Pressure transducer to read the discharge pressure. 11.1.3 Oil Differential Pressure - Calculated value of the oil pressure as follows: Screws without oil pump, discharge psi minus suction psi 11.1.4 Oil Temperature - Either a temperature sensor or a digital input that indicates when a high temperature condition exists. 11.1.5 Discharge Temperature - Either a temperature sensor or a digital input that indicates when a high temperature condition exists. 11.1.6 Motor Amps - Sensor input that measures AMP draw of the compressor. (Optional digital input) 11.1.7 Liquid Temperature - Temperature sensor that can be used to detect a freeze condition 11.1.8 Flow Switch - A digital input that indicates that flow through the chiller barrel exists. There can be one switch per chiller or one for each circuit. 11.1.9 Set point safeties - For a safety to be interrogated, both the associated sensor input and the lockout set point must be active. If a safety trips, the alarm name will consist of the set point name plus additional identification such as point number or circuit number if applicable. The system exercises “smart” safety testing in the following manner: If a safety applies to a circuit and it is an active lockout type of a set point, the first time this safety trips an alarm will be generated and the circuit will be shut down and placed in a safety state. The system will attempt to reactivate this circuit after waiting the length of time specified in this set point, safety down time. If successful the system will continue to run. If the same safety trips the time specified in the lockout delay time, the circuit will be locked off and a manual intervention is required. If the lockout delay time is set to zero, the system will generate a lockout condition the first time that the safety occurs. The time in the safety state and the time between safeties are specified in the individual set points. This enables the times to be unique for each lock out set point.
Most safeties are checked only if the Compressor is running, if he safety is always checked it will be so noted.
72
USER'S MANUAL
The following are a list of safeties that are incorporated in the standard chiller algorithm control. These safeties are checked every second. Note, for a multiple circuit system, each circuit is tested individually. If a safety condition exists, action will be taken with that circuit only, other circuits will continue to function.
11.1.10 Freeze Protection (Safety is always checked) If the leaving liquid temperature drops below the set point value the system, and all circuits, will enter a lockout state and a freeze notification alarm will be generated. You have the option of one freeze protect for the package or individual freeze protections by circuit..
11.1.11 No Flow Protection If the flow switch is for the chiller system, then the entire system will be shut down and automatically restarted when the flow switch is on, indicating that there is flow.
11.1.12 Phase Loss Protection Phase loss, as indicated by the phase loss monitor, will result in the system and all circuits being locked off and a phase loss notification alarm will be generated. No set point is required.
11.1.13 Emergency Stop Emergency stop, as indicated by the emergency stop switch, will result in the system and all circuits being locked off and an emergency stop notification alarm will be generated. No set point is required.
11.1.14 Low Differential Oil Pressure This safety is designed to meet the compressor manufacturer requirements on oil pressure. For the first 5 (60 seconds if setup as Hitachi screw compressors) seconds following a compressor start this safety is NOT checked. For the next 30 seconds, if the oil differential pressure drops below ½ of the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time of that set point, the compressor will be locked out and a low oil alarm generated. After this time period, if the oil differential pressure drops below the value of the set point
11.1.15 Low Suction Pressure If the suction pressure drops below the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time, the compressor will be locked out and a low suction alarm generated. For the first 5 minutes after the compressor has started the set point will be ½ , this enables the set point safety time to be set much tighter for normal operation. This safety is bypassed when the compressor is in the “CMP PUMP DOWN” state. This safety can also be used as a freeze protection based upon the suction PSI.
11.1.16 Unsafe Suction Pressure This safety is similar to the low suction pressure safety except this set point can be set up with a lower value and a very short safety time. If the suction pressure drops below the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time of that set point, the compressor will be locked out and a low suction alarm generated. This safety will always cause a lock out on the first trip requiring a manual reset to restart the compressor. For the first 5 minutes after the compressor has started the safety time is extend by twice the normal time delay, this enables the set point safety time to be set much tighter for normal operation. . This safety is bypassed when the compressor is in the “CMP PUMP DOWN” state.
73
SCREW CHILLER (Air & Water Cooled)
11.1.17 Low Discharge Pressure If the discharge pressure drops below the value of the set point and it remains there for the time specified in the safety time of that set point, the compressor will be locked out and a low discharge alarm generated.
11.1.18 High Discharge Pressure (Safety is always checked) If the discharge pressure rose above the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time of that set point, the compressor will be locked out and a high discharge alarm generated.
11.1.19 High Discharge Temperature (Safety is always checked) If the discharge temperature analog input rises above the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time, the compressor will be locked out and a high temperature alarm generated.
11.1.20 HI Motor Temperature or Motor Fault (Safety is always checked) If the high motor temperature input rises above the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time, the compressor will be locked out and a high motor temperature or motor fault alarm generated.
11.1.21 Hi Oil Temperature If the oil temperature rises above the value of the set point or the digital input turns ON and it remains there for the time specified in the safety time of that set point, the compressor will be locked out and a high oil temperature alarm generated.
11.1.22 Low Motor Ampere If the ampere analog input drop below the value of the set point and it remains there for the time specified in the safety time of that set point, the compressor will be locked out and a low motor amp alarm generated. This alarm can be used to indicate low refrigerant. This safety is bypassed for the first 3 seconds after a compressor has started.
11.1.23 Oil Level Low If oil level drop below the required minimum level, the controller will display the alarm as ‘Low Oil Level”. The safety will bypass for 60 minutes during running and 60 second during the start up of compressor.
