Electrical system

 

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 flashing green light labeled POWER indicates power to the machine. All other normal operation status indicators 

are covered as follows:

Ice machine disposition

Operating conditions

FLASHING

ON or OFF

Legend:

OFF

ON

1.  Ice machine is making ice. 

1. 

Normal running.

2.  Ice machine is not making ice.

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.
