3. Mechanical Bin Control

[a]Proximity Switch

1)This machine uses a lever-actuated proximity switch (hereafter called “mechanical bin control”) to control the ice level in the storage bin.

[b]Explanation of Operation

1)The startup and shutdown of the ice machine is controlled via the controller board. Dip switch number 7 must be in the ON position for the controller board to receive input from the bin control.

(i)The controller board receives a resistance value input via the red K4 connector from the bin control. A resistor wire harness is connected from the bin control to the controller board.

(ii)When the bin control is activated in the bin full position (pushed to the right), a

15.8KΩ signal will be sent to the control board to shut down the unit.

(iii)When the bin control is in the normal position (bin is not full), a 7.9 KΩ reading is sent to the control board to continue operation.

2)During operation, the controller board will only shut down the machine if a 15.8 KΩ signal is received from the bin control during the first 5 minutes of the freeze cycle.

(i)If ice pushes the lever to the right after the first five minutes of the freeze cycle, the controller board will allow the machine to complete the freeze cycle and the following harvest cycle before shutting down the machine. This will prevent incomplete batches of ice from forming on the evaporator.
