Operation
Safety Limits
Safety Limits are stored and indicated by
the control board after three cycles. The
number of cycles required to stop the ice
machine varies for each Safety Limit.
• Safety Limit 1 ‑ If the freeze time
reaches 60 minutes, the control board
automatically initiates a harvest cycle.
If 6 consecutive 60 minute freeze cycles
occur, the ice machine stops.
• Safety Limit 2 ‑ If the harvest time
reaches 7 minutes, the control board
automatically returns the ice machine
to the freeze cycle. If 500 consecutive
7 minute harvest cycles occur, the ice
machine stops.
• Safety Limit 3 If the low refrigerant
pressure control opens, the ice machine
shuts off and starts a 5 minute delay
period. If 3 consecutive low pressure
events occur the ice machine stops and
flashes the harvest light.
Use the following procedures to determine
if the control board contains a safety limit
indication.
• Move the toggle switch to OFF.
• Move the toggle switch back to ICE.
Watch the safety limit lights/harvest light
on the control board. If a safety limit has
been recorded, the corresponding light
will blink once, twice or three times to
indicate which safety limit stopped the
ice machine.
