"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 switch. Referencing the figure below, the normal running position
of the flag is down, and the switch is closed. When the bin fills to the top and ice can no longer move through
the tube, the machine will force the shuttle flag up, opening the switch and 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. In this way, there are no
loads generated that would tend to lift off the lid of the bin.
