12� Troubleshooting
Malfunction
Light does not switch ON n No supply voltage
Light does not switch OFF n Lux setting too high
Sensor switches OFF
despite persons being
present
Sensor does not switch
OFF quickly enough
Sensor does not switch
ON quickly enough when
approached from the front
Sensor does not switch
ON when persons are
present despite it being
dark
Switch not working
Cause
n Lux setting too low
n No motion being
detected
n Stay-ON time still
effective
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 Stay-ON time too short
n Light-level threshold too
low
n Stay-ON time too long
n Reach is reduced when

n Lux setting too low
n Switch deactivated?

Remedy
n Check supply voltage
n Slowly increase lux set-
ting until light switches
ON
n Ensure unobstructed
sensor vision
n Check detection zone
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
n Increase stay-ON time
n Change twilight setting
n Reduce stay-ON time
n Install additional sensors
n Reduce distance
between two sensors
n Sensor deactivated by
switch/button?
n Semi-automatic mode?
n Increase light-level
threshold
n Check DIP switch 3
