Bin Switch
FUNCTION
Movement of the water curtain controls bin switch
operation. The bin switch has two main functions:
1. Terminating the Harvest cycle and returning the ice
machine to the Freeze cycle. This occurs when the
bin switch is opened and closed again within
7 seconds during the Harvest cycle.
2. Automatic ice machine shut-off.
If the storage bin is full at the end of a Harvest
cycle, the sheet of cubes fails to clear the water
curtain and holds it open. After the water curtain is
held open for 7 seconds, the ice machine shuts off.
The ice machine remains off until enough ice is
removed from the storage bin to allow the sheet of
cubes to drop clear of the water curtain. As the
water curtain swings back to the operating position,
the bin switch closes and the ice machine restarts,
provide the 3-minute delay has expired.
SPECIFICATIONS
The bin switch is a magnetically operated reed switch.
The magnet is attached to the lower right corner of the
water curtain. The switch is attached to the
evaporator-mounting bracket.
The bin switch is connected to a varying D.C. voltage
circuit. (Voltage does not remain constant.)
NOTE: Because of a wide variation in D.C. voltage, it
is not recommended that a voltmeter be used to check
bin switch operation.

Caution
The water curtain must be ON (bin switch(s) closed)
to start ice making.
