Dim period to reach turn on 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.

Dependent parameters:
Dimming time (0 = jump to)
Options: 0...2...65,535 s
This parameter can be used to set a soft start by defining how long the output takes to dim up from
0% brightness to the turn on brightness when it receives an ON telegram. This time period refers to
ON telegrams only (1 bit).
•
0 s: jump to: The output switches ON immediately (DALI ON command).
•
1...65,535 s: During this time, the output is dimmed from 0% brightness to the turn on
brightness.
