12. Troubleshooting
Malfunction Cause
Light does not switch ON ■ No supply voltage
■ Lux setting too low
■ No movement detection
Light does not switch OFF ■ Lux setting too high
■ Stay-ON time running out
■ Interfering heat sources:
e.g. fan heater, open
doors and windows,
pets, light bulb/halogen
floodlight, moving objects
Sensor switches OFF despite ■ Stay-ON time too short
persons being present ■ Light-level threshold
too low
Sensor does not switch OFF ■ Stay-ON time too long
quickly enough
2.8-12 m
2-4 m
2.8 m
Remedy
■ Check supply voltage
■ Slowly increase lux
setting until light switches
ON
■ Ensure unobstructed
sensor vision
■ Check detection zone
■ Reduce lux setting
■ Wait until stay-ON time
elapses; reduce stay-ON
time if necessary
■ Check detection zone
■ Select scenario with
lower sensitivity
■ Increase stay-ON time
■ Change twilight setting
■ Select scenario with
higher sensitivity
■ Reduce stay-ON time

Malfunction Cause
Sensor does not switch ON ■ Reach is reduced when
quickly enough when approached from the
approached from the front front
Sensor does not switch ON ■ Lux setting too low
when persons are present
despite it being dark ■ Semi-automatic mode
activated
■ 4 hours OFF activated
Remedy
■ Install additional sensors
■ Adjust reach
■ Reduce distance
between two sensors
■ Increase light-level
threshold
■ Activate fully automatic
mode or switch light ON
at button
■ Deactivate 4 hours OFF
