Automatic operation
picture 3: Detection area, motion detector
The motion detector detects heat motions of people, animals and objects.
- The light is switched on if a person enters the monitored detection area and the brightness
is below the set threshold.
- The light is switched off if no more movement is detected in the detection area and the
follow-up time has elapsed.
In order to avoid light oscillations due to the cooling of a bulb, the motion detector does not
evaluate any signals for approx. 2 seconds after switch-off.
When the ambient brightness increases, the motion detector switches the motion detection off
only when the brightness has dropped below the set brightness for 10 minutes. That prevents
attempts to tamper with the motion detector, e.g. by illuminating it with a torch to prevent
switching-on.
When the ambient brightness drops the motion detection is only evaluated only when the
brightness has dropped below the set brightness threshold for 2 minutes.
4 Operation
Notes on setting the operating mode
The operating mode can be changed using an installation button, NC contact. Depending on the
desired operating mode, the installation button has to be pressed 1 to 4 times for about 0.5 to
1.5 seconds. The pause between two button-presses must not be more than 2 seconds. If the
installation button is pressed more than four times, the automatic mode becomes active.
Behind the adjusters time, lux and sens. (picture 2) there are three coloured LEDs. These
LEDs indicate the selected operating mode.
Operating mode: switch on light for the run-on time, automatic mode
o Press installation button 1 x.
The motion detectors switches on independently of the brightness. Each detected
movement restarts the run-on time again. The motion detector is in automatic mode.
When the load is switched off the yellow LED lights up if a motion is detected. When the
load is switched on the yellow LED lights up continuously.
Operating mode: switch on light for 4 hours
o Press installation button 2 x.
Light switches on for 4 hours.
The green LED lights up.
