ABB i-bus KNX
Planning and application
The function Scene is not continued with a KNX bus voltage failure or light controller supply voltage failure.
The brightness is set, which is selected with voltage failure or recovery in
page 77.
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 will this DALI device actively participate in the function Scene.
A typical function Scene could, for example, appear as follows and is described using the 8 bit scene
telegram as an example:
The task is to implement the room lighting for a presentation with ABB i-bus
devices are used in the room:

Switch actuators for the basis lighting

Blind actuator for shading

DLR/A for dimmable lighting and constant lighting control
