Name (max 40 characters)
Options:
The output can be assigned a name with a maximum of 40 characters.
The name is stored in the ETS database, and also stored in the gateway by downloading the application.
Brightness value when turned on
(output Switch fct)
Options:
This parameter defines the brightness value used when the DALI output switches on after receiving an
ON telegram.
The dimming thresholds set for the group or ballast apply to the individual ballasts and groups.
•
Previous value: The output switches on at the brightness value it was switched off at by the Switch
group object. The brightness value of each ballast and group are saved when they are switched off,
and restored when they are switched back on.
If a ballast or group is OFF when switched off, the previous brightness value is saved as 0% (OFF)
and is switched back on in the same state. This means that the group or ballast will be switched off
unless it has a brightness value other than 0 when switched back on.
Note
The previous brightness value is saved with every OFF telegram on the output unless the output is
already switched off. If this is the case, the OFF state is not saved as the last brightness value on
receipt of another OFF telegram. The output is not switched off if every group or ballast is already
switched off.
If a new OFF telegram is received during dimming down, the current brightness value is saved as the
last brightness value.
In the event of a KNX voltage failure, download or restart, the previous brightness value is lost and is
set to the parametrized turn on brightness value when the gateway supply voltage is restored.
Separate previous brightness values are saved for the ballast/group and the output.
This means that if the output is dimmed or switched on or off by a central telegram, the previous
brightness value for the ballast/group remains unchanged.
