Commissioning
Dim period to reach turn off
brightness
Options:
This group object defines whether the dimming time can be changed via KNX.
•
Fixed fade time: Dimming time is permanently set and cannot be changed via the KNX.
•
Can be changed via object "Flexible time for dimming/fade time": Dimming time can be changed via
the KNX using the Flexible time for dimming/fade time group object.
Note
Flexible dimming time is received via the Output x Flexible time for dimming/fade time group object and
affects various output functions:
•
•
•
•
To use the Flexible dimming time function you first need to enable the output's Flexible time for
dimming/fade time group object in the A Output/Functions parameter window. You also need to select
the function for the parameter that can be changed via KNX. We recommend that you only change one
time via KNX. Otherwise the dimming time has to be rewritten on the ballast every time a function is
called, which impairs function performance.
Note
The Turn off brightness function can be applied to the whole DALI output, all ballasts and all
groups. It must first be enabled in the X Output x functions parameter window along with the
Activate fct Turn off brightness group object.
To define whether a ballast or a group reacts to the Turn off brightness function on the output,
make the settings in the relevant Ballast x or Group x parameter window.
