Control Safeties
Max freeze time – 45 minutes
When exceeded, the controller will attempt another freeze cycle. If the next cycle's freeze time is less
than maximum, the control will continue normal ice making. If the next freeze cycle was too long, the
control will again attempt another freeze cycle. If the freeze cycle is too long three consecutive cycles,
the controller will shut the unit off and it must be manually reset.
Min freeze time – 6 minutes
If the controller switches the machine into harvest within 20 seconds of the minimum freeze time, the
controller will harvest for a preset time and does not stop if the curtain switch opens. If this occurs again
in the next three cycles, the machine will shut down and must be manually reset.
Max harvest time – 3.5 minutes
If the harvest cycle has continued for 3.5 minutes without the curtain opening, the controller will shut the
machine off for 50 minutes and then restart. If there is another the machine will shut the machine off for
another 50 minutes and then restart. If it fails a third consecutive time the controller will shut the machine
down and must be manually reset.
