Note
The minimum and maximum dimming values (dimming thresholds) still remain valid.
The functions Scene, Staircase lighting, Block, Forced operation as well as dimming processes are
interrupted. The states of the timer functions after a download or after KNX bus voltage recovery are to
be set separately in the respective parameter windows of the timer function.
The operating voltage applied to DALI equipment, e.g. ballasts, is a prerequisite for correct behavior of
the DALI equipment.
Reaction on ballast recovery, DALI-
voltage or light controller supply
Voltage recovery
(KNX voltage must be available)
Options:
This parameter determines how a DALI device that has failed behaves if it is has already been detected by
the DLR/A, and does not respond (has failed) and is once again detected by the DLR/A.

actual KNX target state: The DALI device assumes the brightness value, which it has assumed via a
KNX telegram, if it had not failed.

no change: The DALI device does not change its current brightness value after its recovery.

max. brightness value (100 %): After recovery, the DALI device is switched on with the maximum
brightness value or is dimmed to it.

min. brightness value (1 %): .After recovery, the DALI device is switched on with the minimum
brightness value or is dimmed to it.

OFF (0 %): The DALI device is switched off after recovery.
