Troubleshooting - STEINEL IR 180 DALI Manual

11 . Troubleshooting

Malfunction Cause
Light does not switch ON n No supply voltage
n Lux setting too low
n No motion being
detected
Light does not switch OFF n Lux setting too high
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
Sensor switches OFF
n Stay-ON time too short
despite persons being
n Lux setting too low
present
Sensor does not switch
n Stay-ON time too long
OFF quickly enough
Sensor does not switch
n Reach is reduced when
ON quickly enough when
approached from the
approached from the front
front
Sensor does not switch n Lux setting too low
ON when persons are
present despite it being
dark
Switch not working
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 stay-ON time
n Change lux setting
n Reduce stay-ON time
n Install additional sensors
n Reduce distance
between two sensors
n Sensor deactivated by
switch?
n Semi-automatic mode?
n Increase lux setting
n Check DIP switch 3
