QUAD EVAPORATOR MACHINES ONLY
When a safety limit condition causes the ice machine
to stop, the harvest light on the control board
continually flashes on and off. Use the following
procedures to determine which safety limit has
stopped the ice machine.
1. Move the toggle switch to OFF.
2. Move the toggle switch back to ICE.
3. Watch the harvest light. It will flash one or two
times, corresponding to safety limits 1 and 2, to
indicate which safety limit stopped the ice
machine.
After safety limit indication, the ice machine will restart
and run until a safety limit is exceeded again.
When a safety limit condition is exceeded for 3
consecutive cycles the control board enters the limit to
memory and the ice machine continues to run. Use the
following procedure to determine if the control board
contains a safety limit indication.
1. Move the toggle switch to OFF.
2. Move the toggle switch back to ICE.
3. Watch the harvest light. It will flash one or two
times, corresponding to safety limits 1 and 2, to
indicate which safety limit stopped the ice
machine.
When a safety limit condition is exceeded (6
consecutive cycles for safety limit #1 or 500 cycles for
safety limit #2) the ice machine stops, and the harvest
light on the control board flashes on and off. Use the
following procedure to determine which safety limit
has stopped the ice machine.
1. Move the toggle switch to OFF.
2. Move the toggle switch back to ICE.
3. Watch the harvest light. It will flash one or two
times, corresponding to safety limits 1 and 2, to
indicate which safety limit stopped the ice
machine.
After safety limit indication, the ice machine will restart
and run until a safety limit is exceeded again.
