Section VIII - Power$ync II™ Operation

A potentially serious condition could exist if the main motor starter does not respond to the controller’s signal to disengage. The cooling fan motor will not stop as long as the main motor is running so that cooling can be maintained in the event that the starter does not respond to a signal to perform a normal shutdown. If the starter does not respond to a signal to disengage in an emergency, an unsafe condition may result. The Power$ync II™ controller will flash all the LED safety and warning lights to draw attention to this situation, should it occur. It will also display one of the following messages, depending on the unit configuration:

NOTICE! ********* NOTICE!

COMPRESSOR MAIN CONTACTOR

IS NOT DISENGAGING

PULL MAIN DISCONNECT

NOTICE!

REMOTE STARTER

IS NOT DISENGAGING

PULL MAIN DISCONNECT

Pull the main disconnect to cut the power to the compressor. Determine the reason that the starter is not responding, correct the problem and repeat the start-up procedure. As with other faults, loose wiring should be the first item checked. If all wiring to and from the relay board is tight and wiring to the starter auxiliary contacts is tight, a faulty starter may be the problem. Determine the original cause for the shutdown. If the unit was being stopped because there was no air demand, it can be restarted after the starter problem is corrected. If the unit was being stopped due to a detected fault, correct the fault before continuing operation. Do not attempt to run the compressor

in Back-up Mode until all faults have been corrected.

In addition to the sensor check at power-up, the

Power$ync II™ controller continually checks sensors for faults. If the controller receives a signal that is outside its expected range or fails to receive a signal, one of the following messages will be displayed depending on the sensor affected:

There are two probable causes for these displays: a disconnected wire or a failed sensor or transducer. Disconnect the main power supply to the compressor and check the connection at the temperature probe and at the controller. If a loose connection is found, correct the problem and repeat the start-up procedure. If all connections are tight, the problem is a failed sensor or transducer. If a spare part is available, replace and repeat the start-up process. If no spare part is available, contact a service representative. The compressor can be operated in Back-up Mode.
