Reaction on DALI voltage or light
controller supply voltage recovery
Options:

Function switches to standby: The controller switches to the standby state after DALI voltage recovery
or light controller operating voltage recovery. Receipt of a subsequent ON telegram starts control.
This can be implemented via the communication object Fct Activate controller/Status.

No reaction: No function is executed after DALI voltage recovery or light controller operating voltage
recovery. The lighting group assumes the parameterized brightness at DALI bus voltage recovery.
The controller is deactivated, the lighting group is a normal DALI lighting group without additional
function.

Note
Characteristic adjustment can only apply exactly for brightness values set via the DALI Light
Controller. During dimming, irrespective of whether a group command or central dimming
commands are concerned, differences may occur between the set brightness value and the
(simulated) brightness value adjusted in the DALI Light Controller. The reason for this is that the
DALI uses the commands DIM-UP and DIM-DOWN to control the DALI device in small dim steps
with its own DALI characteristic. The DALI characteristic in the DALI device (ballast) cannot be
changed by the DALI Light Controller.
This deviation can, for example, be determined when the brightness value fed back as the status
value after dimming is used directly to set the brightness value. In this case, there may be a
brightness jump.
Brightness value
Options: No reaction
Function switches to standby

Function switches to standby: Light control can be interrupted by a brightness telegram.
The light controller switches to standby mode. The received Brightness value telegram is
implemented. The lighting control can be reactivated by an ON telegram or via the
communication object Switch.

No reaction: A brightness telegram has no effect on the lighting and the light control.
Recall scene
Options: No reaction
Function switches to standby

Function switches to standby: Light control can be interrupted by a scene recall. The light
controller switches to standby mode. The received scene telegram is implemented. The light
controller can be reactivated by an ON telegram or via the communication object Switch.

No reaction: A scene recall has no effect on the lighting and light control.
