Switches 2, 5, and 7 are set to ‘On.’ CONTROLS General — The 30RAP air-cooled scroll chillers contain the ComfortLink™ electronic control system that controls and monitors all operations of the chiller. The control system is composed of several components as listed in the sections below. See Fig. 3-5 for typical control box drawings. See Fig. 6 and 7 for control schematics.

If no compressors have been running for more than 30 minutes and the leaving fluid temperature is greater than the saturated condensing temperature, the wear factor is still used to determine which compressor to start next. If the leaving fluid temperature is less than the saturated condensing temperature, then the control will start either compressor A1 or compressor B1 first, depending on the user-configurable circuit lead-lag value.

A fan stage is decreased when the SCTs of both circuits are less than the Fan Off Set Point (Set PointsHEAD F.OFF) for two minutes. Table 20 shows the number of fan stages, contactors energized and the fans that are on during the fan stage. Unit sizes 035 to 060 have common fan control.

interlock contacts should be rated for dry circuit application capable of handling 5 vdc at 2 mA. SINGLE INTEGRAL PUMP CONTROL — With a single pump, the following options must be configured: • Cooler Pump Control (ConfigurationOPT1CPC) = ON. • Cooler Pump 1 Enable (ConfigurationOPT1 PM1E) = YES. • Cooler Pump 2 Enable (ConfigurationOPT1 PM2E) = NO. With a single integral pump, the Cooler Pump Starter will be energized when the machine is occupied.
If the control starts a pump and the wrong interlock circuit closes for at least 20 seconds, an A189 – Cooler Pump and Aux Contact Input Miswire Alarm will be generated. The unit will be prevented from starting. The control will allow for pump changeover. Two methods will change the pump sequence. Before the changeover can occur, the unit must be at Capacity Stage 0. During changeover the chilled water flow switch input is ignored for 10 seconds to avoid a nuisance alarm.

Under normal operation, the chiller will maintain a constant leaving fluid temperature approximately equal to the chilled fluid set point. As the cooler load varies, the entering cooler fluid will change in proportion to the load as shown in Fig. 20. Usually the chiller size and leaving-fluid temperature set point are selected based on a full-load condition. At part load, the fluid temperature set point may be colder than required.

2. Use the scrolling marquee display to adjust the Cooling Set Point. 3. Fill chilled fluid circuit with clean water (with recommended inhibitor added) or other non-corrosive fluid to be cooled. Bleed all air out of the high points of the system. If chilled water is to be maintained at a temperature below 40 F (4.4 C) or outdoor temperatures are expected to be below 32 F (0° C), a brine of sufficient concentration must be used to prevent freeze-up at anticipated suction temperatures. See Table 28. 4.
Unbalanced 3-Phase Supply Voltage — Never operate a motor where a phase imbalance between phases is greater than 2%. To determine percent voltage imbalance: max voltage deviation from avg voltage % Voltage Imbalance = 100 x average voltage The maximum voltage deviation is the largest difference between a voltage measurement across 2 legs and the average across all 3 legs. Example: Supply voltage is 240-3-60. AB = 243 v BC = 236 v AC = 238 v CAUTION Never charge liquid into low-pressure side of system.
determines the saturated temperature of suction gas. The difference between the temperature of the superheated gas and the saturated suction temperature is the superheat. The EXV board controls the position of the electronic expansion valve stepper motor to maintain superheat set point. The MBB controls the superheat leaving cooler to approximately 9° F (5° C). Because EXV status is communicated to the main base board (MBB) and is controlled by the EXV boards, it is possible to track the valve position.

CAUTION BLK WHT If the existing motor has been removed for inspection or cleaning, be sure that the piston is fully retracted into the motor assembly before installation on the valve. Failure to do so will permanently damage the drive and motor. Replacement motor assemblies are shipped in the retracted position and may be installed as received.

HEATER CABLE — Optional factory-installed cooler and/or hydronic package heaters are cycled based on the input from the outside-air temperature sensor. These heaters, when installed, are designed to protect the cooler and/or hydronic package from freezing down to –20 F (–29 C). Power for these heaters is supplied from the main unit power. The input from the low pressure transducer provides a backup cooler freeze protection package.

If the drive remains in CURRENT LIMIT too long, it can trip into a CURRENT OVERLOAD fault (PF). Data Fault: User data and OEM defaults in the EPM are corrupted. High DC Bus Voltage Fault: Line voltage is too high; Deceleration rate is too fast; Overhauling load.

uncommon for actual pump duty to be different than what was anticipated at time of selection. In many cases, it may be desirable to make some field modifications to obtain optimum pump performance. Before any pump modifications are made, it is recommended that actual pump performance be verified and compared to the applicable pump curve. See base unit installation instructions. This can be done in a variety of ways: 1. If pump impeller diameter is known: a.
core face. Reduce pressure and use caution to prevent damage to air centers. • Check condenser coils for debris, clean as necessary. Every month: • Check moisture indicating sight glass for possible refrigerant loss and presence of moisture. Every 3 months (for all machines): • Check refrigerant charge. • Check all refrigerant joints and valves for refrigerant leaks, repair as necessary. • Check chilled water flow switch operation. • Check all condenser fans for proper operation.

Below are the factory settings for the fixed high pressure switch. 30RAP UNIT SIZE 010-060 CUTOUT psig 650 reset automatically before the motor protector resets, which may take up to 2 hours. High Discharge Gas Temperature Protection — Units equipped with digital compressors have an additional thermistor located on the discharge line, If discharge temperature exceeds 265 F (129.4 C), the digital compressor will be shut off.
Table 41 — Troubleshooting SYMPTOMS Cooler Circulating Pump Does Not Run CAUSE Power line open Control fuse or circuit breaker open REMEDY Reset circuit breaker. Check control circuit for ground or short. Reset breaker and replace fuse. Check the controls. Find the cause of trip and reset breaker. Check connections. Check wiring and rewire if necessary. Check line voltage — determine location of voltage drop and remedy deficiency. Check motor winding for open or short. Replace compressor if necessary.

The UPC Open controller is mounted in the main control box per unit components arrangement diagrams. TO ADDRESS THE UPC OPEN CONTROLLER — The user must give the UPC Open controller an address that is unique on the BACnet* network.
APPENDIX D — OPTIONAL BACNET COMMUNICATIONS WIRING (cont) CONFIGURING THE BAS PORT FOR BACNET MS/ TP — Use the same baud rate and communication settings for all controllers on the network segment. The UPC Open controller is fixed at 8 data bits, No Parity, and 1 Stop bit for this protocol's communications. If the UPC Open controller has been wired for power, pull the screw terminal connector from the controller's power terminals labeled Gnd and HOT.
APPENDIX D — OPTIONAL BACNET COMMUNICATIONS WIRING (cont) Fig. E — BT485 Terminator Installation temperature rating specifications list two acceptable alternatives. The Halar specification has a higher temperature rating and a tougher outer jacket than the SmokeGard specification, and it is appropriate for use in applications where the user is concerned about abrasion. The Halar jacket is also less likely to crack in extremely low temperatures.
