APPLICATION DATA Maximum chilled water flow Unit operating range The maximum chilled water flow (> 0.09 l/s per kW or < 2.8 K temperature difference) is limited by the maximum permitted pressure drop in the evaporator. It is provided in the following table : a - Select a non-standard evaporator with one water pass less which will allow a higher maximum water flow rate. b - Bypass the evaporator as shown in the diagram to obtain a highter temperature difference with a lower evaporator flow rate.

MAJOR SYSTEM COMPONENTS AND OPERATION DATA which separates the two refrigerant circuits. The tubes are 3/4" or 1" diameter copper with enhanced surface inside and out. There is just one water circuit with two water passes. Geared twin screw compressor • 30HXC and 30GX units use 06N geared twin screw compressors • 06NA are used on 30GX (air-cooled condensing application) • 06NW are used on 30HXC (water-cooled condensing application) • Nominal capacities range from 39 to 80 tons.
the EXV flashes to vapor, further subcooling the liquid that is maintained at the bottom of the economizer. This increase in subcooling provides additional capacity. Since no additional power is required to accomplish this, the efficiency of the machine also improves. The vapor that flashes will rise to the economizer where it passes to the compressor and is used as needed to provide motor cooling.
Compressor Protection Module (CPM) This module monitors several of the compressor safeties and controls four of the outputs used to control the compressor. The CPM monitors compressor current, compressor voltage, high pressure switch status, and compressor motor temperature. It controls the compressor contactor oil solenoid, motor cooling solenoid, and star delta transition relay. Each CPM sends the PSIO its circuit motor temperature, alarm status and the output status of the module.
The CPM communicates on the COMM3 communication bus to the PSIO module. Proper operation of the CPM board can be verified by observing the three LED's located on the board. The left LED is red and blinks to indicate that the module is powered and operating correctly. The middle LED is yellow and blinks when there is an automatic reset alarm condition. The yellow LED will remain on and will not blink for manual reset alarm conditions.

Head pressure control General The microprocessor controls the condenser fans (30GX) or analogue water valve (30HXC) to maintain the saturated condensing temperature to a configurable setpoint. The fans will be staged (30GX) or water valve controlled (30HXC) based on each circuit's saturated condensing temperature and compressor status. Water-cooled units (30HXC) operating at less than 20°C for entering condenser water require the use of head pressure control.

PRE-START-UP PROCEDURE START-UP AND OPERATION Do not attempt to start the chiller until the following checks have been completed. Actual Start-up System Check 1 - Check all auxiliary components such as the chilled fluid circulating pump, air-handling equipment, or other equipment to which the chiller supplies liquid. Consult the manufacturer’s instructions. If the unit has field-installed accessories, be sure all are properly installed and wired correctly. Refer to the unit wiring diagrams.
TROUBLESHOOTING Single Circuit Stoppage The 30HXC/GX Screw chiller control has many features to aid the technicians in troubleshooting. By using the keypad and display module and the status function, actual operating conditions of the chiller are displayed while the unit is running. The test function allows for operational checkout of compressor loaders, EXV’s, solenoids and other components while the chiller is stopped.

Low oil pressure alert criteria and setpoints (Alert 40 to 43) Two oil pressure setpoints are used. Oil setpoint 1 and oil setpoint 2. Oil setpoint 1 (oil pressure differential Po - Pe) is calculated as follows: 30HXC Oil setpoint 1 = 70 kPa if saturated suction pressure ≤ 240 kPa Oil setpoint 1 = 86 kPa if saturated suction pressure > 240 kPa but < 450 kPa Oil setpoint 1 = 100 kPa if saturated suction pressure > 450 kPa.
MAINTENANCE To add charge to the 30HXC systems Refrigerant Charging - Adding Charge 1. Make sure that the unit is running at full-load, and that the cooler leaving fluid temperature is in the range of 5.6 - 7.8 °C. IMPORTANT These units are designed for use with R-134a only. DO NOT USE ANY OTHER refrigerant in these units. CAUTION When adding or removing charge, circulate water through the condenser (HX) and cooler at all times to prevent freezing.
5. Add 2.5 kg of liquid charge into the cooler using charging valve located in the top of the cooler. 6. Allow the system to stabilize and then recheck the liquid temperature. Repeat step 5 as needed allowing the system to stabilize between each charge addition. Slowly add charge as the sightglass begins to clear to avoid overcharging. Oll Charging - Low oil recharging Addition of oil charge to 30HX/GX systems 1.
Service replacement compressor EXV Troubleshooting Procedure Compressor rotation control Follow steps below to diagnose and correct EXV/ Economizer problems. Correct compressor rotation is one of the most critical application considerations. Reverse rotation, even for a very short duration, can seriously affect the reliability of the compressor. The reverse rotation protection scheme must be capable of determining the direction of rotation and stopping the compressor within 300 milliseconds.
