BIN LEVEL PROBE
The bin level probe accessory will place the ice machine
in a full bin state when ice lowers the temperature to 36°
F or less. The touchscreen will display Program Mode On
during the full bin state. A lower ice level in dispensers will
prevent overfilling or dispense wheel or motor damage.
• The bin probe reads actual temperature and must be
connected to the T5 terminal on the control board.
• The control board recognizes the bin level probe
automatically when installed. If the bin level probe
has not been recognized by the control board, restore
factory defaults and run the startup wizard.
Normal Operation
The control board will initiate a full bin cycle and a 10
minute time delay when both of the following occur:
1. The control board receives a temperature input of 36°
F or less from the bin probe (T5 thermistor) at the end
of the freeze cycle.
2. The temperature reading remains at or below 36° F
throughout the entire harvest cycle.
The ice machine will restart when the delay period ends
and the bin probe reads 37° F or higher. Ice making will
resume at the Initial Start-Up or Start-Up After Automatic
Shut-Off (See “Sequence of Operation” on page 60).
