o Attach decor ring.
i To make the short-time operation independent of brightness, turn lux adjuster (5) to 3.
Setting the brightness threshold
Only when the brightness drops below the threshold will the light be switched on when there is
motion in the detection area. The brightness threshold is infinitely adjustable in a range from
approx. 0 to 80 lux and day operation . In so doing, the symbol stands for brightness-
independent switching and the symbol for switching in case of darkness.
o Pull off decor ring.
o Turn the lux adjuster (5) to the required position (Figure 4).
i Should the motion detector no longer react to detected movements in Night mode, 2
setting, turn the adjuster back somewhat towards 3.
o Attach decor ring.
Setting the sensitivity
The motion detector possess automatic adjustment to the ambient conditions. Normally, the
adjuster sens should be set to maximum sensitivity.
o Pull off decor ring.
o Set the sensitivity using the adjuster sens (3).
i If there are unwanted switching operations, reduce the sensitivity.
o Attach decor ring.

6.2 Troubleshooting
Light does not switch on, LED lights up upon detection
Cause: The ambient brightness is greater than the set brightness threshold.
Increase the brightness threshold using the lux adjuster (5).
Light does not switch on, LED does not light up
Cause 1: Detection area is limited by push-on cover.
Remove or adjust push-on cover.
Cause 2: Sensitivity is set too low.
Turn sens adjuster (3) in max direction.
Light switches on, although no-one is in the detection area.
Cause: Interference sources in the detection area, e.g. heating, ventilation, cooling light bulbs.
Reduce the detection area with push-on cover or reduce the sensitivity with the sens
adjuster (3).
