Safety Limits - Koolaire STH045 8/15 Technician's Handbook

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 cycling the toggle switch
Off/On and starting a new ice making cycle.
A safety limit is indicated by a flashing light on the
control board.
Safety Limit 1
If the freeze time reaches 60 minutes, the control
board automatically initiates a harvest cycle.
• After 3 consecutive 60 minute cycles control board
light SL#1 light will flash on/off at 1 second
intervals.
• If 6 consecutive 60-minute freeze cycles occur, the
ice machine stops and the SL#1 light on the
control board will be on continuously.
Safety Limit 2
If the harvest time reaches 3.5 minutes, the control
board automatically returns the ice machine to the
freeze cycle.
• If three consecutive 3.5 minute harvest cycles
occur the SL#2 light on the control board will flash
on/off at 1 second intervals.
• If 100 consecutive 3.5 minute harvest cycles
occur, the ice machine stops and the SL#2 light on
the control board will be on continuously.
