If function light controller is active (running):
Behaviour on ...
With these three parameters, you can set how the lighting group of the DLR/A reacts with active lighting
control if the following telegrams have been received:
Switch on
Relative dimming
Brightness value
Scenes
There is an additional possibility to parameterize the behavior of the controller after DALI bus voltage
recovery or light controller supply voltage recovery.
Receipt of the telegram value 1 on the communication objects Switch or Switch/status
Receipt of a telegram on the communication object Relative dimming
Receipt of a telegram on the communication object Brightness value
Receipt of a telegram on the communication object Recall scene
Switch on
Options: no reaction
Deactivate lighting control
Restart control with brightness value

no reaction: An ON telegram on the communication object Switch has no effect on the lighting
and the lighting control.

By an ON telegram via the communication objects Switch or Switch/status, the light control is
interrupted. The lighting control can be reactivated by an ON telegram via the communication
object Activate fct controller/status.

Restart control with brightness value: With activated light control, the switch on brightness and
light control are restarted with an ON telegram.
Note
An OFF telegram (with the value 0) to the communication object Switch or Switch/status always
causes a switch off of the lighting group and the light control. The light control is in standby mode
and recommences with light control via an ON telegram (with the value 1) received on the
communication object Switch or Switch/status or Activate fct controller/status
Relative dimming
Options: no reaction
Deactivate lighting control
setpoint = new sensor value (temporary)

no reaction: A dimming telegram to the communication object Relative dimming has no effect
on the lighting and the lighting control.

Deactivate lighting control: The lighting control can be interrupted by a dimming telegram via
the communication object relative dimming. The lighting control can be reactivated by an ON
telegram via the communication object Activate fct controller/status.

setpoint = new sensor value (temporary): The new sensor value (current brightness) is
accepted as a temporary setpoint. After a brief interruption – until the temporary setpoint is
accepted – the light control will continue with the new setpoint. The old setpoint is restored at
the next activation of the light control, e.g. switch on via communication object Switch or via the
communication object Activate fct controller/status.
