SensorSAFE board guide
LEDs, when illuminated, indicate the following:
PWR (board power), CLN (clean button pressed
WTR and WM outputs disabled), ICE (ice
dispensing activated), WTR (water dispensing
activated).
Terminals: L1 (incoming power, hot), L2 (neutral
terminals), WTR (power terminal for water
solenoid), WM (power terminal for wheelmotor),
CLN (terminals for clean cycle switch).
Note: SOL terminal not used in 12 series
dispensers.
Lens/sensor troubleshooting
1. Turn dispenser power switch off and remove splash panel.
2. Disconnect wires from WTR and WM terminals on board.
3. Gently remove sensor/mounting block from splash panel.
4. Inspect lens and sensor, clean if necessary.
5. Restore dispenser power and test sensor by passing hand in front of sensor.
6. If LED on board turns on, sensor is operational. Re-assemble dispenser.
