MAJOR DIAGNOSTIC FAILURE

CORRECT PROBLEM NOW

PRESS ➔ ENTER TO RERUN DIAGNOSTICS

If the computer is unable to complete its diagnostic check, it will display this message. Disconnect the main power supply to the compressor and check all electrical connection to all boards and sensors. Reapply power and press ENTER to rerun the diagnostic check. If the machine again displays this message, contact your service representative. The compressor can be operated in Back-up Mode.

NOTICE

U19 MEMORY FAILURE

CONTACT YOUR SERVICE REPRESENTATIVE

This display indicates that the setup memory cannot be accessed by the operating program. Probable causes are badly corrupted data or a mechanical failure of the memory chip. Contact your service representative for proper diagnosis and repair. The compressor can be operated in Back-up Mode.

One of the following three messages may be displayed if wiring to the starter is changed or if a remote starter is installed. These messages could indicate an error in the wiring which would cause the drive motor to start as soon as power is applied to the compressor or a failed component in the starting system. Power$ync II™ will alert the operator if it attempts to shut down the compressor and the compressor does not respond (see Warning and Shutdown Displays). If power is disconnected, and then reapplied without having corrected the fault, one of the following displays will be visible:

NOTICE

A CONTROL RELAY IS NOT DISENGAGED REFER TO YOUR SERVICE MANUAL OR CONTACT YOUR SERVICE REPRESENTATIVE

This display indicates that the control relay that signals the starter to engage is not functioning properly. The cause may be a jammed or shorted START button or relay. Immediately disconnect the power to the compressor and determine the cause of the malfunction. If the cause cannot be determined and corrected, contact your local service representative. Do not attempt to operate

the compressor in Back-up Mode.

NOTICE

MAIN CONTACTOR IS NOT DISENGAGED REFER TO YOUR SERVICE MANUAL OR CONTACT YOUR SERVICE REPRESENTATIVE

NOTICE

WYE CONTACTOR IS NOT DISENGAGED REFER TO YOUR SERVICE MANUAL OR CONTACT YOUR SERVICE REPRESENTATIVE

These messages indicate a starter that is not functioning properly or has been incorrectly wired into the system. If the compressor has a starter that was not provided by Quincy Compressor, this message may indicate that the starter has been incorrectly wired to the auxiliary contacts. Low supply voltage can cause starters to “chatter”. The arcing associated with starter “chatter” can weld the contacts together (preventing the starter from disengaging) or cause catastrophic destruction of the starter. Immediately disconnect the power to the compressor and determine the cause of the malfunction. If the cause cannot be quickly and easily corrected, contact your service representative. Do not attempt to operate the

compressor in Back-up Mode.
