Light sensor X* allocated to
* (X = A, B, C, D represents one of the 4 possible light sensors)
Options:
With this parameter, every light sensor can be assigned to any of the first 4 lighting groups.
If several light sensors are assigned to a lighting group, a calculated sensor value is used as the actual
value (input variable) for the constant lighting control. The calculated actual value is entered in the
parameter window Gx: controller which is enabled as soon as the lighting group features the additional
Light control function. The options lower sensor value, upper sensor value or average sensor value are
available.
For further information see:
The programmer is responsible to ensure that a useful assignment of the Light Sensor is undertaken. ETS
does not undertake a plausibility test.
Note
For ideal constant lighting control, every controllable lighting group is assigned to exactly one sensor.
This sensor should be positioned in the room, so that ideally it is not influenced by any other source of
artificial lighting. Furthermore, no direct incidence of light and no reflections may influence the Light
Sensor.
