3.2. Settings
3.2.1. General
At delivery, the light sensor parameters are set as follows (factory settings):
sensor mode
sensitivity
LED motion indicator
Use DIP switches 1 and 2 to set the presence detector to the desired test mode and activate the LED motion indicator.
To set the sensitivity, use DIP switches 3 and 4. Figure 7 shows how to set the DIP switches for the desired sensitivity
of the light sensor (minimum, low, high, maximum).
3.2.2. Test modes
The presence detector has two test modes: a test mode for the lux value and a test mode for the motion detector operation.
a) Test mode for the lux value: measuring the daylight level
Set DIP switches 1 and 2 to ON. The lighting is now switched off.
Slowly turn the LUX key clockwise (towards maximum) until the LED indicator illuminates. The lux setting is then
equal to the daylight level the light sensor is measuring. If there is sufficient daylight in the room, turn the LUX key
counterclockwise until the LED indicator switches off. Leave the LUX key in this position.
If the LUX key is turned counterclockwise, the lighting switches off when there is less daylight.
If the LUX key is turned clockwise, the lighting switches off when there is more daylight.
Finally, reset DIP switches 1 and 2 to OFF.
b) Test mode for the motion detector operation
Set DIP switch 1 to OFF and DIP switch 2 to ON. The lighting is switched on for five seconds. The LED motion
indicator indicates that the motion detector is activated.
Attention: The walking is not affected by daylight.
Finally, reset DIP switch 2 to OFF.
3.2.3. LED motion indicator
Set DIP switch 1 to ON and DIP switch 2 to OFF to activate to LED motion indicator. The LED indicator remains illuminated
as long as motion is detected.
3.2.4. Detection range
If the presence detector is mounted at a height of 2.5 m, it detects movement within a diameter of 20 m in a 360° zone. This
presence detector has a lens area with a diameter of 5 m and more than 618 fields, which guarantees optimal registration
of even the smallest body movements.
If a section of the detection area is to be excluded from detecting any motion, cover the sensor lens using the cover cap
supplied. This allows the maximum range to be reduced from 20 m to 12 m, 5 m or 3 m. The detection angle of 360° can
be decreased in steps of 45° (fig. 7).
