Safety Limit #2: If the harvest time reaches
3.5 minutes, the control board automatically returns
the ice machine to the Freeze cycle.
Control board with orange label and 302 on
microprocessor.
If 500 consecutive 3.5 minute harvest cycles occur, the
ice machine stops.
Control board with black microprocessor.
If three consecutive 3.5-minute Harvest cycles occur,
the ice machine stops.
Safety Limit Stand-By Mode: (QDUALC Only)
The first time a safety limit shut down occurs, (three
consecutive long freeze or harvest cycles) the ice
machine will turn off for 60 minutes (Stand-By Mode).
During the Stand-By Mode the harvest light will be
flashing continuously and a safety limit indication can
be viewed. After 60 minutes the ice machine will
automatically restart to see if the problem re-occurs. If
the same safety limit is reached a second time (three
more consecutive long freeze or harvest cycles) the
ice machine will initiate a safety limit shut down and
remain off until it is manually restarted. During a safety
limit shut down the harvest light will be flashing
continuously.
