Electrical system

ATTENTION!
To prevent circuit breaker/Hi-amp overload, wait 5 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 flashing green light labeled POWER indicates power to the machine. All other normal operation status
indicators are covered as follows:

Error faults:
The Horizon PC board monitors various operating parameters including high pressure, auger gearmotor
amperage limits, clogged drain, and low water alarm conditions. There are three types of errors namely "soft"
(time delay) "hard" (reset), and "run".
§ Soft errors will automatically reset after the 1 hour time delay or can be reset by cycling power.
§ Hard errors must be reset on the control board.
§ Run errors will give an indication of a problem, but will allow continuous normal operation.

Operating conditions
OFF ON or OFF
1. Normal running.
2. Normal time delay. When the bin fills 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.
