SAFETY LIMITS
Safety limits are stored and indicated by the control board.
The number of cycles required to stop the ice machine
varies for each safety limit.
Safety limits can be reset by pressing the On/Off button
and starting a new ice making cycle.
A safety limit shutdown is indicated by the red Service light
on the touch pad.
If the freeze time reaches 45 minutes, the control board
automatically initiates a harvest cycle.
• After 3 consecutive 45 minute cycles control board
light SL#1 along with the touch pad Service (wrench)
light will flash on/off at 1 second intervals.
• If 6 consecutive 45-minute freeze cycles occur, the ice
machine stops and the SL#1 light on the control board
and the Service (wrench) light on the touch pad will be
on continuously.
Safety Limit 2
• If the harvest time reaches 3.5 minutes, the control
board automatically energizes the water pump and
extends the harvest cycle another 3.5 minutes (7
minutes total).
• If the ice damper does not open and close within the
7 minute harvest cycle the ice machine enters a water
thaw cycle for 170 seconds.
• If the damper does not open/close within the 170
second thaw cycle, a second thaw cycle starts.
• The control board automatically initiates a freeze
sequence when the thaw cycle(s) is complete.
• If 3 consecutive 7 minute harvest/thaw cycles occur,
the ice machine stops.
