Parameter window Light sensor

In the parameter window Light sensor, the Light Sensors LF/U 2.1 (up to 4 possible) are assigned to the
first 4 lighting groups of the DLR/A. Only the first 4 lighting groups feature a function for constant lighting
control in combination with the light sensor. However, it is possible to parameterize each of the 8 lighting
groups as a slave. If the corresponding master lighting group is parameterized with constant lighting
control, the slave lighting group is also included.
If several light sensors are assigned to an output, it is necessary to define which sensor value is used as
the actual value (input variable) for the control circuit.
For further information see:
Free light sensor setting
to the control light group 1...4
Options:
A free light sensor assignment to one of the first 4 lighting groups can be parameterized with these
parameters.

no: In this default setting, each of the 4 light sensors is assigned to exactly one lighting group. In
ascending order, the light sensor is allocated to light sensor input A of lighting group 1, light sensor B
to lighting group 2, through light sensor D to lighting group 4.

yes: The individual parameters on the parameter page are enabled. In this way it is possible to assign
the light sensor to any of the first 4 lighting groups.
Note
Please only use real settings. ETS does not check parameterization.
