Brightness on KNX bus voltage recovery
and download
Options:
This parameter defines how the ballast/group ballasts react after a download, on KNX bus voltage
recovery, or after light controller supply voltage recovery.
•
No change: The brightness of the ballast/group does not change. Ballasts or groups that are switched
off remain off.
•
Last value before failure: The ballast/group is restored to its pre-failure state. To be reinstated after
KNX bus voltage recovery the brightness value must have been set for at least two seconds before a
KNX voltage failure or a download.
•
Maximum brightness value (100%): The ballast/group switches on at or dims to the maximum
brightness value.
•
Min. brightness value (1%): The ballast/group switches on at or dims to the minimum brightness value.
•
OFF (0%): The ballast/group switches off.
Note
The minimal dimming/maximum brightness values (dimming thresholds) still remain valid. If the set
brightness values are outside the dimming thresholds, the threshold value is adopted.
The Scene, Staircase lighting, Block and Forced operation functions as well as dimming processes are
interrupted. The state of the functions after a download or after KNX bus voltage recovery must be set
separately in the appropriate function parameter window.
For the correct response to trigger, the DALI equipment must have a voltage applied and must be
operated according to the standard.
