12� Troubleshooting
Malfunction Cause Remedy
Light does not switch ON
n No supply voltage
n Lux setting too low
n No motion being
detected
n Check supply voltage
n Slowly increase lux set-
ting until light switches
ON
n Ensure unobstructed
sensor vision
n Check detection zone
Light does not switch OFF
n Lux setting too high
n Stay-ON time still
eective
n Interfering heat sources:
e.g. fan heater, open
doors and windows,
pets, light bulb / halo-
gen floodlight, moving
objects
n Position Wi-Fi device
very close to the sensor
n Reduce lux setting
n Wait until stay-ON time
elapses; reduce stay-
ON time if necessary
n Use stickers to mask
out stationary sources
of interference
n Increase distance
between Wi-Fi device
and sensor >3m
Sensor switches OFF
despite persons being
present
n Stay-ON time too short
n Light-level threshold too
low
n Increase stay-ON time
n Change twilight setting
Sensor does not switch
OFF quickly enough
n Stay-ON time too long n Reduce stay-ON time
Sensor does not switch
ON quickly enough when
approached from the front
n Reach is reduced when
approached from the
front
n Install additional sensors
n Reduce distance
between two sensors
Sensor does not switch
ON when persons are
present despite it being
dark
n Lux setting too low n Sensor deactivated by
switch/button?
n Semi-automatic mode?
n Increase light-level
threshold
Switch not working
n Switch deactivated? n Check DIP switch 3
