K. Bin Control Check
An infrared sensor controls the level of ice in the dispenser unit/ice storage bin.
IMPORTANT
• Make sure the icemaker has been installed as outlined in this manual and that the
water supply is on.
• Make sure S1 Dip Switch 7 is in the "ON" position. This allows the control board to
monitor the infrared sensor.
1. Infrared Sensor Check
1) Turn off the power supply.
2) Remove the front panel, top panel, and control box cover.
3) Conrm that control board S1 dip switch 1, 2, and 3 are in the proper position for your
application. "See IV.K.2. Infrared Sensor Shutdown Delay."
4) Move the control switch on the control box to the "ICE" position, then move the power
switch to the "ON" position.
5) Turn on the power supply to start the automatic icemaking process. Conrm the green
LED on the infrared sensor turns on. This LED conrms 20VDC power to the sensor.
6) Make sure the "GM" LED on the control board is on. See Fig. 18. There is a delay of
at least 30 seconds before the "GM" LED turns on after power-up. After the "GM" LED
turns on, press the "SERVICE" button on the control board to bypass the 5-minute
compressor delay. WARNING! Risk of electric shock. Care should be taken not to
touch live terminals. Confrim the "COMP" LED turns on.
