Instruction Manual

K. 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.

• Conrm 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) Make sure the power switch is in the "OFF" position and that the power supply is off.

3) Remove the control box cover.

4) Conrm that control board S1 dip switch 1, 2, 3 are in the proper position for your

application. See "II.K.3. Infrared Sensor Shutdown Delay."

5) Turn on the power supply. Make sure the control switch is in the "ICE" position, then

move the power switch to the "ON" position.

6) The green LED on the infrared sensor turns on. This LED conrms 20VDC power to the

sensor.

7) 30 seconds after the upper oat switch closes, the control board "GM" LED turns on.

See Fig. 18. After "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.
