Scene

The DLR/A facilitates the integration of the 8 lighting groups in 14 scenes.
The scene parameterized once in the ETS can be used in the following functions:

Normal scene recall via the communication objects 8 bit scene (1 byte) or Recall scene (1 bit)

In function Staircase lighting, scenes 13 and 14 are used directly for parameterization of the staircase
lighting. If in function Staircase lighting, the scenes 13 or 14 are to be parameterized directly via
parameter window Scene 13 and Scene 14, the options for Time for dimming up (soft start), Staircase
time, Time for dimming down after light on (Warning before light turned off) and Basis brightness hold
time undertaken in the parameter window Staircase lighting are lost.
The scene value of a scene can be parameterized in the ETS in
saved via the KNX. If storing of the scene is triggered via communication object Store scene or the
respective 8 bit scene telegram, the currently set brightness values of the lighting group are saved as the
new scene value. Only the lighting groups, which are also members of the scene, are used during storage.
The other lighting groups are not influenced.
The normal scene can be recalled via the 1 bit communication object Recall scene or via a 1 byte
communication object 8 bit scene.
With 1 bit control, a received telegram on communication object Recall scene (Scene x/y) has the following
function:

Telegram value 0 = recall scene x

Telegram value 1 = recall scene y
The following function table results with the 1 byte communication object 8 bit scene:
Other numeric values do not affect the function Scene.

Important
The light scene settings remain stored in the DLR/A even after a KNX bus voltage failure or light
controller supply voltage failure. If a ballast has to be exchanged, the light scenes are immediately
available without further commissioning.
