Troubleshooting BIR3 Components
CAUTION: Turn off water supplies to unit before troubleshooting.
Problem: An individual operating station drips and fails to shut off.
Cause:
There is debris trapped between the diaphragm and the valve seat.
Solution: Remove debris between diaphragm and the valve seat.
Disconnect the plug from the battery to the circuit board of the problem valve . Remove the three #8 Phillips-head screws that
hold the solenoid valve assembly together . Be careful not to lose the armature or spring . Remove the diaphragm . Remove any
particles that are 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 . 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 . Reconnect the battery plug . Turn on water supplies to the unit .
Problem: An individual operating station fails to turn on or off.
Cause:
Excessive line pressure.
Solution: Install pressure reducing valve.
Check the static line pressure . If the pressure exceeds 80 psi, install a pressure reducer valve at the street main . Excessive line
pressure (over 60 psi) will shorten the life of any valve .
Problem: An individual operating station fails to turn on or off.
Cause:
A dead or faulty battery.
Solution: Test the station to determine cause and replace battery if required.

Disconnect the plug from the battery to the circuit board of the problem valve .
Disconnect the plug from the battery to the circuit board of an adjacent valve .
Connect the battery plug from the adjacent working valve to the problem valve . Wait
for ten seconds . Activate the problem station’s sensor ten times . The station should
turn on . If the station turns on, and cycles normally, replace the battery .
Cause:
Faulty sensor eyes.
Solution: Test station to determine cause; replace sensor eyes if required.
Disconnect the sensor cable from the circuit board of the problem valve . Disconnect
the sensor cable from the circuit board of an adjacent working valve . Connect the
sensor cable from the adjacent working valve to the problem valve . Activate the
problem station’s sensor . The station should turn on . If the station turns on and cycles
normally, replace the sensor eyes .
Cause:
Faulty solenoid valve.
Solution: Test station to determine cause; replace solenoid valve if required.
Remove the screw, circuit board and standoff from the problem valve . Remove the
battery holder . With a good working battery, briefly contact the solenoid valve directly
with the battery as shown in Open Valve figure to right . The contact should cause the
valve to open . With the battery holder removed, briefly contact the solenoid valve with
the battery in the position shown in Closed Valve figure to right . This should cause
the valve to close . If the valve does not operate when directly contacted with a good
battery, and the solenoid valve has already been cleaned as outlined at the beginning
of this troubleshooting section, replace the solenoid valve .
If problems persist:
Pass your hand in front of the problem station, while at the same time looking to see
if the indicator light on the circuit board flashes (the indicator light is located near the
hole in the circuit board where the standoff is mounted) . If it does not flash, and the
battery and sensor eyes have already been tested as outlined above, the problem
may be with the circuit board . Make a note of the numbers printed on the circuit
board, then contact your Bradley representative for assistance .
