H. Bin Control Check
An infrared sensor is used as the primary bin control to control the level of ice in the
dispenser unit/ice storage bin. A mechanical bin control is used as a backup bin control.
IMPORTANT
• Make sure the icemaker has been installed as outlined in this manual and that
the water supply is on.
• Conrm S1 dip switch 7 is in the "ON" position. This allows the control board to
monitor the infrared sensor along with the mechanical backup bin control.
1. Infrared Sensor Check
1) If not already removed, remove the front panel.
2) Move the power switch to the "OFF" position, then unplug the icemaker from the
electrical outlet.
3) Remove the control box cover.
4) Conrm that control board S1 dip switch 1, 2, 3 are in the proper position for your
application. See "II.H.2. Infrared Sensor Shutdown Delay."
5) Plug in the icemaker. Make sure the control switch is in the "ICE" position, then move
the power switch to the "ON" position.
6) Conrm the green LED on the infrared sensor turns on. This LED conrms 20VDC
power to the sensor.
7) Make sure the "GM" LED on the control board is on. See Fig. 10. 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. Conrm the "COMP" LED turns on.
