Troubleshooting
Malfunction
Light does not switch ON
Light does not switch OFF
Sensor switches OFF in spite
of persons being present
Sensor does not switch OFF
quickly enough
Sensor does not switch ON
when persons are present
despite it being dark
Disposal
Electrical and electronic
equipment, accessories and
packaging must be recycled in
an environmentally compatible
manner.
Do not dispose of
electrical and
electronic equipment
as domestic waste!
Cause
No BUS voltage
n
Light level set too low
n
No movement being detected
n
Room light level too bright
n
Stay-ON time still effective
n
Interference from unintended
n
sources of motion, e.g.: ceiling
fan, air-conditioning, ventilation,
open doors and windows
Stay-ON time too short
n
Light-level threshold too low
n
Stay-ON time too long
n
Lux setting too low
n
EU countries only:
Under the current European
Directive on Waste Electrical
and Electronic Equipment and
its implementation in national
law, electrical and electronic
equipment no longer suitable
for use must be collected
separately and recycled in an
environmentally compatible
manner.

Remedy
Check BUS voltage
n
Slowly increase twilight
n
setting until light switches
ON
Ensure unobstructed sensor
n
vision
Check detection zone
n
Reduce twilight setting
n
Wait until stay-ON time
n
elapses, reduce stay-ON
time if necessary
Mask out stationary sources
n
of interference by reducing
sensitivity
Increase stay-ON time
n
Change twilight setting
n
Reduce stay-ON time
n
Sensor deactivated by
n
switch / button?
Semi-automatic mode?
n
Increase light-level
n
threshold
