AUTOMATIC SHUT-OFF

6. Automatic Shut-off
When the storage bin is full at the end of a harvest sequence, the sheet of cubes fails
to clear the ice damper and will hold it down. After the ice damper is held open for 7
seconds, the ice machine shuts off. The ice machine remains off for 3 minutes before it can
automatically restart.
The ice machine remains off until enough ice has been removed from the storage bin to
allow the ice to fall clear of the damper. As the ice damper swings back to the operating
position, the bin switch re-closes and the ice machine restarts (steps 1 - 2), provided the 3
minute delay period is complete.

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 with the On/Off toggle switch by starting a new ice making cycle.
A safety limit is indicated by a flashing Service Light on the control board.
• Safety Limit 1 - If the freeze time reaches 60 minutes, the control board automatically
initiates a harvest cycle. Three cycles outside the time limit = 1 hour Stand-by Mode.
• Safety Limit 2 - If the harvest time reaches 3.5 minutes, the control board automatically
returns the ice machine to the freeze cycle. 3 cycles outside the time limit = Safety Limit
(must be MANUALLY reset).
• Safety Limit Stand-by Mode: The first time a safety limit shutdown occurs, the
ice machine turns off for 60 minutes (Stand-by Mode). The ice machine will then
automatically restart to see if the problem reoccurs. During the Stand-by Mode the
harvest light will be flashing continuously and a safety limit indication can be viewed.
If the same safety limit is reached a second time (the problem has reoccurred), the
ice machine will initiate a safety limit shutdown and remain off until it is manually
restarted. During a safety limit shutdown, the harvest light will be flashing continuously.
