If function Light controller is active (running):
Reaction on ...
With these three parameters, you can set how the lighting group of the DLR/S reacts with active light
control if the following telegrams have been received:
Switch on
Relative dimming
Brightness value
Scenes
It is also possible to parameterize the reaction 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 light control
Restart control with brightness value

No reaction: An ON telegram on the communication object Switch has no effect on the lighting
and the light controller.

Deactivate light control: An ON telegram via the communication objects Switch or
Switch/Status interrupts light control. Light control can be reactivated by an ON telegram or via
the communication object Fct Activate controller/Status.

Restart control with brightness value: With activated light control, the switch on brightness and
light controller 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 controller. The light controller 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 Fct Activate controller/Status.
Relative dimming
Options: No reaction
Deactivate light 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 light controller.

Deactivate light control: Light control can be interrupted by a dimming telegram via the
communication object Relative dimming. Light control can be reactivated by an ON telegram or
via the communication object Fct Activate 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 – light control will continue with the new setpoint. The old setpoint is restored at the
next activation of light control, e.g. switch on via communication object Switch or via the
communication object Fct Activate controller/Status.
