BIN SWITCH
FUNCTION
Movement of the water curtain/ice dampers control 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 30 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/ice dampers and
holds it open. After the water curtain/ice dampers
are held open for 30 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/ice dampers.
As the water curtain/ice dampers swing back to the
operating position, the bin switch closes and the ice
machine restarts, provide the 10-minute delay has
expired.
Important
The water curtain/ice dampers must be ON (bin switch
closed) to start ice making.
SPECIFICATIONS
The bin switch is a magnetically operated reed switch. The
magnet is attached to the lower right corner of the water
curtain and both ends of ice dampers.
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.
