Problem Possible Cause Corrective Action
Faucet is non-responsive Baery voltage low. Change out baeries
Electronic box connector cable
has bent or broken pins.
Check to see if pins are missing, bent, or broken. If yes, then the
electronic box needs to be replaced
Sensor lens could have surface
damage, scratches, or deposit
build ups.
Inspect the sensor lens. May require cleaning with a damp cloth
or spout/sensor replacement
Sensor lens could be obstructed
by environmental factors such
as highly reecve surfaces or
bright lighng condions.
If this is the case, then adjust the dip switch sengs for sensor
sensivity per the diagram on page 16 (switches 7 and 8). Direct
sunlight could eect unit operaon. Do not allow direct sunlight
onto unit.
If one mode does not help try one of the following:
-switching 7 to O to set the sensor to the lowest sensivity level
(detecon range may be less for all hand types).
-switching to alternate mode using switch 8; mode A or B depend-
ing on current conguraon
Reset sensor aer dip switch changes.

Ghost Acvaon Sensor lens could be obstructed
or environmental factors such as
highly reecve surfaces and/or
bright sunlight condions could
be present.
Check/clean sensor lens of any debris or buildup and remove any
obstrucons. If sunlight or IR interference is a factor, refer to page
16 “Sensor Sensivity” and adjust faucet for Mode B operaon.
Also, decreasing the sensivity seng (switch 7) may help. If
possible/needed, adjust lighng condions and/or remove nearby
reecve surfaces.
Reset sensor aer dip switch changes.
Sensor faucet is leaking

counter
Mounng hardware is not ght
-
ened suciently (faucet shank,
