Troubleshooting
Fault / error
Cause
Light does not switch on and/or
switches off if presence is detected
and in darkness
Lux value is set too low; detector set on semi-automatic; light was switched off manually via push
button or SendoClic; person not within detection range; obstruction(s) interfere with detection;
switch-off time set too short
Light stays on with detection of presence
despite sufficient brightness
Lux value is set too high; the light was just switched on manually via push button or SendoClic
(wait 30 minutes); detector is in test mode
Light does not switch off and/or light
switches spontaneously on when
no one is present
Wait for switch-off delay (self-learning); thermal sources of interruption in the detection area: Fan
heater, incandescent lamps / halogen spotlight, moving objects (e.g. curtains hanging in an open
window); start up does not run smoothly.
Error flashing (4 x per second)
Malfunction during start-up phase or during operation; device is not fully functional!
Diagnosis bit no. 0
ETS parameter invalid
The combination of brightness level and room correction factor is invalid.
Diagnosis bit no. 1
The combination of brightness level
and room correction factor is invalid.
The parameters are outside the setting limits, see parameter
„Continuation of room correction factor“ page 20
Diagnosis bit no. 2
The combination of alternative bright-
ness level and room correction factor
is invalid.
The parameters are outside the setting limits, see parameter
„Continuation of room correction factor“ page 20
Diagnosis bit no. 3
Brightness level via bus value is invalid.
The received value is outside the value range of the brightness level of 5..2000 lux.
Diagnosis bit no. 4
Alternative brightness level via bus value
is invalid.
The received value is outside the value range of the brightness level of 5..2000 lux.
Diagnosis bit no. 5
Teach-in is not possible
The current measured brightness value is outside the value range of the brightness level of
5–2000 lux. ; <Control type> switching: The brightness level to be acquired is not possible in
combination with the set <Brightness difference to A channel light> on B channel light.
Diagnosis bit no. 6
The brightness level with "measurement
off" setting is not possible with constant
light control.
The brightness level zero (0) is received via bus object; the "measurement off " parameter value
is sent to the presence detector via SendoPro.
