Malfunction
Cause
Remedy
Light does not switch ON
■
No supply voltage
■
Lux setting too low
■
No movement detection
■
Check supply voltage
■
Slowly increase lux
setting until light switches
ON
■
Ensure unobstructed
sensor vision
■
Check detection zone
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
■
Reduce lux setting
■
Wait until stay-ON time
elapses; reduce stay-ON
time if necessary
■
Check detection zone
■
Select scenario with
lower sensitivity
Sensor switches OFF despite
persons being present
■
Stay-ON time too short
■
Light-level threshold
too low
■
Increase stay-ON time
■
Change twilight setting
■
Select scenario with
higher sensitivity
Sensor does not switch OFF
quickly enough
■
Stay-ON time too long
■
Reduce stay-ON time
Sensor does not switch ON
quickly enough when
approached from the front
■
Reach is reduced when
approached from the
front
■
Install additional sensors
■
Adjust reach
■
Reduce distance
between two sensors
Sensor does not switch ON
when persons are present
despite it being dark
■
Lux setting too low
■
Semi-automatic mode
activated
■
4 hours OFF activated
■
Increase light-level
threshold
■
Activate fully automatic
mode or switch light ON
at button
■
Deactivate 4 hours OFF
