quickly enough
Sensor does not switch 'ON'
quickly enough when ap-
proached from the front
Sensor does not switch 'ON'

Cause
í No supply voltage
í Twilight level set
too low
í No movement being
detected
í Ambient brightness
too high for selected light
level
í Stay-'ON' time running out
í Interference from heat
sources (IR sensor only),
e.g.: fan heater, open doors
and windows, pets, light
bulb/halogen floodlight,
moving objects
í Stay-'ON' time too short
í Light-level threshold too
low
í Stay-'ON' time too long
í Reach is reduced when
approached from the front
too low
í Twilight level set
- 19 -
Remedy
í Check supply voltage
í Slowly increase
light threshold level until
light switches 'ON'
í Ensure unobstructed sen-
sor vision
í Check detection zone
í Increase light level
setting
í Wait until stay-'ON' time
elapses; reduce stay-'ON'
time if necessary
í Use stickers to mask out
stationary sources of inter-
ference
í Increase stay-'ON' time
í Change light threshold
í Reduce stay-'ON' time
í Install additional sensors
í Reduce distance between
two sensors
í Sensor deactivated by
switch/button?
í Semi-automatic mode?
í Increase light level
