Lens/sensor troubleshooting
1. Turn dispenser power switch off.
2. Remove splash panel.
3. Disconnect wires from output terminal(s) (WTR, WM) on board.
4. Gently remove appropriate sensor/mounting block assembly from panel by moving block sideways until edge
of block clears retaining tab of panel.
5. Inspect lens and sensor assembly for foreign material and remove using non-abrasive cleaner.
6. Turn dispenser power on and test sensor by moving hands through activation area
(no closer than 5mm (3/16") in front of sensor).
7. If LED on board turns on and off, sensor is working properly and dispenser may be reassembled. If LED
does not come on, switch sensor leads on board and retest. If the opposite LED comes on, board is defective
and must be replaced. If LED does not come on, sensor is defective and must be replaced.
