Section VIII - Power$ync II™ Operation

The Power$ync II™ controller also performs continuing checks on itself while the compressor is in operation. If it detects a fault, it will display one of the following two messages:

NOTICE!

COMPRESSOR HAS SHUT DOWN

**NOTICE** COMMUNICATION FAILURE

REFER TO YOUR SERVICE MANUAL

The Power$ync II™ controller continually checks its communication pathways between boards, even when no pertinent information is being passed. This is done to confirm that all communication pathways are functioning and ready to accept and process signals. If the controller fails to receive the proper response to its attempt to confirm that the communication pathways are functioning properly, it will try two more times and then shut the compressor down. Call your local service representative to correct this problem. The compressor can be operated in Back-up Mode.

PKG. DISCH TEMP_______

COMPRESSOR HAS SHUT DOWN

**NOTICE** HIGH DISCHARGE TEMPERATURE

TAKE CORRECTIVE ACTION

This display indicates that the controller has detected a high temperature condition at the temperature probe installed in the discharge line from the package to the plant air. This could be the result of a mechanical failure or it could be the result of low coolant flow. This is a serious condition. Do not attempt to restart the compressor until the cause of the shutdown has been determined and corrected. The compressor will not restart as long as the high temperature condition exists. Call your service representative if you cannot determine and correct the cause of the shutdown.

Power$ync II™ is connected to and monitors the state of the motor starter and overload. Should the controller detect a fault condition or detect that a component is not responding to commands, it will illuminate the appropriate LED on the schematic and display one of the following messages:

2 INLET TEMP ______

COMPRESSOR HAS SHUT DOWN NOTICE! HIGH STAGE 2 INLET TEMP TAKE CORRECTIVE ACTION

2 DISCH TEMP ______

COMPRESSOR HAS SHUT DOWN

NOTICE! HIGH STAGE 2 DISCH TEMP

TAKE CORRECTIVE ACTION

1 DISCH TEMP ______

COMPRESSOR HAS SHUT DOWN

NOTICE! HIGH STAGE 1 DISCH TEMP

TAKE CORRECTIVE ACTION

High temperature shutdowns could be caused by high ambient temperatures. Verify that the ambient temperature is within the operating limits of the compressor. A failed or broken vent fan could also cause high temperatures. For water-cooled units, the water temperature or flow might be outside the operating limits of the compressor or the cooler might need cleaning. For air-cooled units, the air flow might be blocked, the fan or fan motor may have failed, the thermal mixing valve may have failed or the cooler may need cleaning. High Stage 2 discharge temperature can be caused by a high delta-pressure across stage 2. This could be caused by a blowdown valve failure.

FLUID PRESSURE ______

COMPRESSOR HAS SHUT DOWN

NOTICE! LOW FLUID PRESSURE

TAKE CORRECTIVE ACTION

Low fluid pressure may be caused by a failed fluid pump or regulating valve.
