"Bin Full" Detection System - Follett C33984 Operation And Service Manual

"Bin full" detection system

The Follett Horizon ice machine incorporates a unique "bin full" detection system, that consists of the shuttle and
actuator. The shuttle incorporates a flag and sensor. Referencing the figure below, the normal running position of
the flag is down, out of the sensor. When the bin fills to the top and ice can no longer move through the tube, the
machine will force the shuttle flag up into the sensor, shutting the machine off. The shuttle actuator, located above
the ice bin allows the ice to curl up within it when the bin is full to contain any forces. In this way, there are no loads
generated that would tend to lift off the lid of the bin.
