Motion and presence detector
When changing the device function, the settings of the previous device function are saved
and reactivated on changing again.
Setting the sensitivity
The sensitivity can be set individually for each PIR sensor.
■ Press PIR A, PIR B or PIR C button for less than 10 seconds.
■ Within 5 seconds, press the 25%, 50%, 75% or 100% button.
Sensitivity is set.
Limiting the detection field
The detection field of the motion detector can be limited by switching off one or two PIR
sensors. Since the detection areas of the PIR sensors overlap, there is no distinct demarcation
of the blocked out detection area. If all the PIR sensors have been switched off, then the device
works as a twilight switch.
■ Press the PIR A, PIR B or PIR C button for longer than 10 seconds.
The appropriate PIR sensor is switched off and the detection field is limited.
By pressing the PIR A-C button all the PIR sensors are switched on again at 100% sensit-
ivity. Individual PIR sensors can be switched off by setting a sensitivity for the PIR sensor.
Setting the switch-on brightness
One of four predefined brightness thresholds (see table) or one individual brightness threshold
can be set (see Saving current brightness as the switch-on brightness). If the device is set as a
motion detector, then the brightness is measured on the device. If the device is set as a pres-
ence detector, then the brightness is measured on the work surface.
■ Press the appropriate button (see table).

Saving the current brightness as the switch-on brightness
The Teach function can be used to save the current brightness as a switch-on brightness.
Do not shade the device during the measuring process.
■ Create the desired lighting situation, e.g. switch light on or off.
■ Press the ũ button for longer than 10 seconds.
The Teach function is activated, the current brightness is saved as the switch-on bright-
ness and is used after a maximum of 3 minutes.
If a value greater than 2000 lux is saved, the motion detector switches to day operation in-
dependent of the brightness.
Setting fixed run-on time
■ Press the 30 s Ů, 2 min Ů, 5 min Ů or 30 min Ů button.
If the run-on time is shortened, then it only becomes active after the device has switched
off once. To cancel a running run-on time, set the special function Continuous on for ex-
ample and then switch back to Automatic operation (see Operation).
