Infrared (IR) — Sensor and Solenoid Valve Troubleshooting

If a station is not functioning properly it is most likely either the solenoid valve or the sensor.

Troubleshooting multi station units is fairly easy, as you can swap parts (actually just by changing the wires) and use the process of elimination to figure out which of the 2 parts is causing the problem.

How the system operates:

1.The transformer sends 24 volts to the sensor.

2.The sensor acts only as a switch.

3.When hands go into the active field of the sensor, the sensor activates and sends a power signal on to the solenoid valve.

4.The power signal activates and opens the solenoid valve which allows the water to flow to the sprayhead. The solenoid valve stays open allowing water to flow as long as it is receiving a signal form the sensor (hands remain in the active field).

5.When hands are removed from the active field, the sensor turns off (note some models have a slight delay feature built-in.) and shuts off the power signal to the solenoid valve.

CAUTION: Turn off water supplies to unit before troubleshooting.

			Make sure the center orifice and both small side orifices are open.
			3. Reassemble in reverse order, being careful not to overtighten the Phillips-head
			screws or you may crack the plastic valve body. Tighten until the armature plate
			makes contact with the plastic body.

			problem valve.
			b. If the adjacent valve fails to turn on, inspect the wires from the sensor cable
			and do the following:
			• make sure there are no breaks and that the fully insulated disconnect
			terminals are firmly crimped in place;
			• turn off the electrical and water supplies;
			• reconnect to the adjacent valve and turn on the water supplies to the unit;
			• pass your hand in front of the sensor. If the station still fails to turn on,
			replace the sensor.
