Compressor Overload:
The interface will display the message shown below if the compressor motor
safety overload switch opens. The machine will stop immediately. The compressor overload will
reset automatically after the compressor has time to cool off.

COMP. OK
When the compressor overload resets the interface will display “COMP. OK”. It will be necessary to
press “A” on the operator interface to restart the machine.
Long or Short Cycle Safety: The interface will display the messages shown below if there is a long
or short cycle condition. The machine will stop upon indication of either of these conditions. A long
cycle is defined as a freeze cycle that lasts for a period of one hour. An open drain valve, leaking hot
gas valve or defective compressor could cause this. The short cycle safety will stop the machine after
three consecutive freeze cycles of less than five minutes duration. Short cycling can be caused by a
restriction in the liquid line, inadequate make-up or circulating water, or a defective freezer pressure
switch.

! CAUTION !
When the operator interface indicates a fault, something has gone wrong. Every effort
should be made to discover the reason for the fault. Do not simply reset the fault and resume
operation. The underlying cause will likely reoccur, interrupt ice supply and potentially
damage equipment.
