Table 6: Control Panel Component Functions
Component Function
AX Auxiliary trip indicator for manual motor starters. Switch opens, turning off the motor when
cutter or pump motor starter trips.
CB2 Overload and short circuit protection for control circuit and crankcase heater. (400/460V
machines only)
CC Provides power to the compressor motor. Continuously energized during freezing and thawing.
Auxiliary contacts control main power for control circuit components, crankcase heater,
control relay, and harvest timer.
CCR Capacity Control Relay. Controls the loading of the compressor. Y3 – 25%, Y4 – 100%.
CR Control Relay. Controls sequencing of freezing and thawing circuits. Energized during thawing
period.
CU Fan motor starter (manual motor starter and contactor). Starts and stops cutter motor.
Provides short circuit and over current protection. Stops cutter motor and ice machine in the
event of a mechanical or electrical malfunction that results in excessive motor amperes.
DS Disconnect switch (CE and Australian approved machines only).
ET Indicates hours of machine operation. Energized when compressor is operating.
FC Cutter motor starter (manual motor starter and contactor). Cycles the fan motor(s) of air-
cooled condenser on and off. Automatically activated by the System 450 (air-cooled machines
only). Provides short circuit and over current protection. Stops fan motors in the event of a
mechanical or electrical malfunction that results in excessive motor amperes.
FU1&2 Overload and short circuit protection for control circuit and crankcase heater.
FU10-60 Short circuit protection for optional power monitor.
P Pump motor starter (manual motor starter and contactor). Starts and stops pump motor.
Provides short circuit and over current protection. Stops water pump motor in the event of a
mechanical or electrical malfunction that results in excessive motor amperes.
PBL1 Light indicates a compressor fault. The push button resets the compressor module fault by
pressing and holding for 5 seconds. The push button is also used to immediately stop machine
operation in case of an emergency.
PB2 Starts machine for manually harvesting. Initiates a harvest period whenever this button is
pushed with the
Clean/Off/Ice selector switch in the Ice position and machine operating in a
freeze period.
PF Stops the machine when there is a power failure or interruption. Also, stops the machine when
the high/low pressure switch, oil pressure safety control, pump overload, cutter overload,
compressor overload, or the control circuit breaker is tripped. If the
Stop button is pushed, any
of the safeties tripped, or there was a power outage, the machine must be manually restarted
by pushing
Start .
