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 (Symphony Plus only) is off, the ice machine will go through the normal

start-up sequence when the bin level control signals the control board for ice .

Quiet Night/Sleep cycle (Symphony Plus only)

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 .
