Reaction on download or
KNX bus voltage recovery
Options:
This parameter determines how the DALI device of the lighting group reacts after a download or at KNX
bus voltage recovery.
no change: The brightness of the lighting group does not change. DALI devices, which are switched
off, remain off.
Status before failure: The lighting group is brought to the state which it had before the download or
KNX bus voltage failure. The brightness value must be set for at least two seconds before KNX volt-
age failure or a download in order to ensure that it is set again after KNX bus voltage recovery.
max. brightness value (100 %): The lighting group is switched on or dimmed with the maximum
brightness value.
min. brightness value (1 %): The lighting group is switched on or dimmed with the minimum brightness
value.
OFF (0 %): The lighting group is switched off.
Note
The minimum and maximum dimming values (dimming thresholds) still remain valid.
The functions Scene, Staircase light, Sequence as well as dimming processes are interrupted. The
states of the timer functions after a download or after KNX voltage recovery are to be set separately in
the respective parameter windows of the additional function.
The ballast operating voltage is a prerequisite for correct response of the DALI equipment, e.g. ballast.
Reaction on DALI bus voltage failure or
failure gateway supply voltage
Options:
This parameter defines how the DALI devices of the lighting group react if communication with the DALI
devices via KNX is not possible due to a DALI bus voltage failure or Gateway supply voltage failure.
