Troubleshooting Adaptive IR
Problem
Cause
Solution
LED not
illuminated.
No power is
getting to the
sensor.
Check for power at the 110 VAC wall outlet and from the wires from the 24 VAC transformer. If there
is 110 VAC power at the wall outlet, but no power from the transformer, touching leads from the
transformer while plugged in or a power surge may have burned out the transformer. Add surge
protection at the outlet if a power surge is suspected and replace the transformer. If 24 VAC power is
being supplied from the transformer, check for loose wire connections and check connections against
the wiring diagram.
Fast blink
Sensor is
detecting
something in
it's view and
water should
be on (power
is being
sent to the
solenoid)
If the sensor is blinking fast, the water is turning on and there is nothing in the detection area,
disconnect the power for at least 30 seconds. This will allow the sensor to loose it’s memory and be
reset. Reconnect the power and wait 2 full minutes to allow the sensor to relearn the environment
before attempting to activate. The sensor may take up to 8 minutes to readjust if it activated during
those 2 minutes.
If the condition persists, make sure the LEDs at the ends of the sensor cables are pushed all the way
in to the backs of the lenses.
If the sensor is blinking fast and the water is not turning on, go through the troubleshooting guide for
the solenoid.
Slow blink
Sensor is
detecting
something in
it's view and
the water is off
(power is not
being sent to
the solenoid).
The sensor has detected a stationary object in its view for more than 30 seconds and shut off power
to the solenoid valve. Remove the object, if it is still in the bowl, and reset the sensor as explained
above.
Blinking SOS
(3 short, 3
long, 3 short)
The sensor
has detected
an overload
condition and
shut down
to protect it's
circuits.
Check connections against the wiring diagram. This condition usually means the solenoid valve is not
properly wired. After correcting any wiring error, it will be necessary to reset the sensor as explained
above.
If you need further assistance, please call your local Bradley representative. Please call us at 1-800-Bradley if you need the name
and telephone number of your local Bradley representative.
There is a LED diagnostic light built into the small black box housing the circuitry for the sensor. Below is a list of what the signals
from the LED mean. Use this list to troubleshoot the sensor.
