Commissioning
Light sensor X* is allocated to
* (X = A, B, C...H represents one of the eight possible light sensors)
Options:
With this parameter, every light sensor can be assigned to any of the first 8 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 light control. The specification for the calculated actual value is made
in the Gx: Controller parameter window, which is enabled as soon as the lighting group features the
additional Light control function. The options Smallest sensor value, Largest sensor value or Average
sensor value are available.
For further information see:
The programmer is responsible for ensuring that a useful assignment of the Light Sensor is performed.
The ETS does not perform 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 in such a way that ideally it is not influenced by any other
source of artificial light. Furthermore, no direct incidence of light and no reflections may influence the
Light Sensor.
