COMPRESSOR HAS TIMED OUT AND SHUT DOWN

WILL NOT RESTART AUTOMATICALLY

COMPRESSOR NOT IN SCHEDULED SEQUENCE

When compressors are running in Network Mode, individual compressors can be scheduled out. If a particular compressor ID is left out of a sequence for a particular schedule, the network will consider that compressor out of service. This feature can be used to ensure that only certain machines run at certain times of the day. A network of three machines, ABC for example, can schedule a sequence, BC for example, that leaves one of the machines completely out. Machines that are not in the scheduled sequence will not be turned on during that schedule, regardless of system demand. If there is a possibility that the system demand might require all machines, do not leave any machines out of any sequences.

NOTICE!

THE STAGE 1 BLOWDOWN MUFFLER MAY BE BLOCKED PLEASE CHECK FOR OPERATION COULD CAUSE OVER-PRESSURE SHUTDOWN!

NOTICE!

THE STAGE 2 BLOWDOWN MUFFLER MAY BE BLOCKED PLEASE CHECK FOR OPERATION COULD CAUSE OVER-PRESSURE SHUTDOWN!

These two messages are warning indicators that the blowdown passages may be blocked or degrading. These will trip if the pressure during blowdown fails to reach 5 psig during an unloaded condition. This is an important message to see; the LED indicator for STAGE 2 DISCHARGE PRESSURE or HIGH INTERSTAGE PRESSURE will blink when this condition is detected. If this is allowed to continue, degradation of the compressor is likely.
