Safety Limits
In addition to standard safety controls, the control
board has built in safety limit controls which protect the
ice machine from major component failures.
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 all models - 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 single evaporator models - If the
harvest time reaches 3.5 minutes, the control
board automatically returns the ice machine to the
freeze cycle. If 500 consecutive 3.5 minute harvest
cycles occur, the ice machine stops.
• Safety Limit 2 Multiple evaporator models - 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.
