Bin Switch - Manitowoc S300 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 cu rtain/ice dampers m ust b e 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/ice dampers. The switch is attached to
the right bulkhead wall.
The bin switch is connected to a varying D.C. voltage
circuit. (Voltage does not remain constant.)
Because of a wide variation in D.C. voltage, it
NOTE:
is not recommended that a voltmeter be used to check
bin switch operation.
