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 - 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 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.
