Transition time for scene
Options:
This parameter sets the duration, in which the scene retrieval of the dimming process for all lighting groups
of the scene are completed together. If the dimming process is completed, the lighting groups of the scene
have achieved the parameterized brightness value of the scene.
Example
Lighting group 1, which is dimmed from 10 % to 100 %, and lighting group 2, which is dimmed from
90 % to 100 %, achieve the parameterized brightness value of the scene simultaneously.

Jump to: When a scene is recalled, the lighting groups are switched on immediately with the
parameterized brightness value of the scene.

0.7 s...90.5 s: When a scene is recalled, all the lighting groups of the scene are dimmed from their
current brightness value to the parameterized brightness value within this time duration.

Flexible dimming time – settable via KNX: With a scene recall, all the lighting groups of the scene are
adjustable from their current brightness value, to dim them to the parameterized brightness value,
using the flexible dimming time which can be set via the KNX. The value can be modified via the
communication objects Fade time (DALI format) or (KNX format).

Overwrite scene on download
Options:

Yes: The scene values and the scene transition times in the DALI devices of the lighting group are
overwritten after a download by the values set in the ETS.

No: The scene values and the scene transition times in the DALI devices of the lighting group are not
overwritten after a download by the values set in the ETS. If no scene values have been stored, they
are set by the DLR/S to the maximum brightness.
Note
If there is a KNX bus voltage failure the brightness value of scenes set via the KNX are still retained.
With a recall scene or with a store scene, only the lighting groups, which are constituents of the scene,
are taken into consideration.
