This group object is enabled if the Enable Group object "Flexible time for dimming/fade time..." parameter is set to Yes in the
X Output: Functions (Turn off brightness/Burn-in/Slave offset/Partial failure) parameter window, p. 67.
This group object defines whether the dimming time can be changed via KNX.
There is only one flexible dimming time per DALI output; it affects all parametrized flexible dimming times on the output:
•
•
•
•
Whether the group or ballast responds to flexible dimming time is defined in the Group x or Ballast x parameter window.
The transition times correspond to the fade times defined in DALI standard EN 62386-102.
Telegram value:
Function
Flexible time for dimming/fade time
(DALI format (0...15))
Dependent on parameter
Dimming time for turn on/off value
Dimming time for brightness value
Dimming time for slave brightness value
Scene transition time
0...15: Corresponds to the fade times according to DALI
The fade time is specified as the time required to change the lamp power from the current brightness
value to the required target brightness.
If a lamp is switched off, the preheat and ignition time are excluded from the fade time.
The default value is set at 2.0 s until the first value is received.
During a KNX failure or download, the fade time received via the KNX is lost and replaced by the
default value of 2.0 s.
See the next group object description for other group object formats.
