ATTENTION!
To prevent circuit breaker overload, wait 15 minutes before restarting this unit. This allows the
compressor to equalize and the evaporator to thaw.
Normal control board operation
The PC board indicator lights provide all the information necessary to determine the machine's status. Green
indicator lights generally represent “go” or normal operation; Yellow indicators represent normal off conditions; Red
indicators generally represent alarm conditions, some of which will lock the machine off.
A ashing green light labeled POWER indicates power to the machine. All other normal operation status indicators
are covered as follows:
Ice machine disposition Operating conditions
FLASHINGON or OFF
Legend:
OFFON
1. Ice machine is making ice. 1. Normal running.
2. Ice machine is not making ice.
2. Normal time delay. When the bin lls with ice, the LOW BIN
light goes out momentarily and the refrigeration and auger
drive systems immediately shut down. (Note: The fan motor
will continue to run for 10 minutes to cool condenser) The TIME
DELAY light comes on, initiating the time delay period. When
the time delay expires, the machine will restart provided that the
LOW BIN light is on.
