Normal operation – Stage 8

When the dwell time of 20 minutes has expired, the 

TIME DELAY LED goes off. If 5 seconds of ice has been 

dispensed and the 

SLEEP CYCLE LED is off, the ice machine will go through the normal start-up sequence when 

the bin level control signals the control board for ice.

Ice Dispense Input

Quiet Night/Sleep cycle

The board monitors ice dispensing through a line voltage input to P15. If the ice dispense has not be initiated for 

more than 5 seconds during the 20 minute time delay, the 

SLEEP CYCLE LED comes on. The machine will stay 

off for 12 hours unless 5 seconds of dispensing is seen. After 12 hours, the 

SLEEP CYCLE LED goes out and the 

ice making will resume if the bin thermostat is closed. The sleep cycle dispense duration is adjustable using the 

DIP switches on the control board.
