ABB i-bus KNX
Planning and application
The Scene function is not continued if there is a KNX voltage failure or light controller operating voltage
failure. The brightness is set which is selected with voltage failure or recovery in the
Gx Fault, page 81.
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 Scene function.
A typical Scene function might be 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 basic lighting

Blind actuator for shading

DLR/S for dimmable lighting and constant light control
