8.16 Detector Light Factor
The presence detector performs the brightness measurement at a certain
distance from the surface of the desk. If the brightness at the location of
the detector and the brightness at the surface of the desk differ too greatly,
constant lighting control does not generate the required brightness. If this
is the case, it helps to adjust the sensitivity of the detector. The adjustment
can be made using the "Detector Light Factor" function.
The light value factor is set to a value of 2.5 ex works. If the light meas-
urement shows that the brightness at the desk is less than the specified
light target value, a factor of 2.5 is too high and the light value factor must
be reduced. If the measured brightness is greater than the specified light
target value, you must set a higher light value factor.
Setting the light value factor:
1. Use a lux meter to measure the brightness at the desired location,
e.g. at the surface of a desk.
2. Compare the measured value with your specified light target value.
The comparison indicates whether you need to reduce or increase the
light factor.

7. End programming mode by pressing the
button.
8. Use a lux meter to compare the brightness at the desired location with
the specified light target value once again.
9. Repeat steps 3 to 7 until the measured brightness and the light target
value are almost the same.
The light value measurement is adjusted.
