Bin Switch - Manitowoc Indigo Series Technician's Handbook

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 3-minute
delay has expired.
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.
