Planning and Application
The function Scene is not continued with a KNX voltage failure or gateway operating voltage failure. The
brightness is set, which is selected with voltage failure or recovery on the
page 64.
If the ballast operating voltage fails on an individual DALI device, the brightness value will stop and will not
be reintegrated into the ongoing Scene when the ballast operating voltage recovers. Only after the next
scene recall this DALI device will actively participate in the function Scene.
A typical function Scene could, for example, appear as follows and is described using the 8 bit scene tele-
gram as an example:
