Parameter window - Gx Fault

In this parameter window, the reaction of the lighting group to failure and recovery of the KNX/DALI
voltage, light controller supply voltage or a ballast is parameterized.
Reaction on KNX bus, DALI or
light controller voltage failure
Options:
This parameter defines how the DALI devices of the lighting group react if communication with the DLR/A
via KNX is not possible due to a KNX bus voltage failure, a DALI short-circuit or failure of the light
controller supply voltage.
A download is comparable with a KNX bus voltage failure, whereby the lighting group initially assumes the
parameterized value of brightness here. The value for KNX bus voltage recovery is set at the end of the
download.

no change: The brightness of the lighting group does not change. DALI devices, which are switched
off, remain off. The timer functions, such as Staircase lighting and lamp burn-in, are not continued.

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 factory default setting of the ballast is changed with this parameter (system failure level).
