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.

Problem Cause Solution

An individual

operating station

fails to shut off and

drips.

There is debris

trapped between

the diaphragm

and the valve

seat.

Remove debris between diaphragm and the valve seat.

1. Remove the three #8 Phillips-head screws that hold the solenoid valve assembly

together. Be careful not to lose the armature or spring.

2. Remove the diaphragm. Remove any particles that have been trapped between the

diaphragm and the valve seat. Rinse off the diaphragm and inspect for damage.

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.

4. Reconnect the wiring per the appropriate diagram on next 4 pages.

An individual

operating station

fails to turn on.

A failed coil for

the valve or

loose electrical

connection to the

terminal.

Test the station to determine cause.

1. Disconnect the wires from the coil of an adjacent valve. Disconnect the wires from

the problem valve and reconnect to the adjacent valve.

2. Turn on electrical and water supplies to the unit. Pass your hand in front of the

sensor of the problem station, and the adjacent station should turn on.

a. If the adjacent station turns on and cycles normally, replace the coil on the

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.
