Dimming time for rel dimming 0...100%
(Relative dimming fct)
Options:
This parameter defines the time in which a dimming process goes from 0...100%. This dimming time only
affects dimming actions received via the Relative dimming group object.
The dimming times correspond to the DALI fade times stored in the ballast.
Note
When setting dimming times of less than 32 seconds, note that they will be mapped to the
nearest DALI fade time. The conversion is as follows:
Turn on

7...9
10...13
14...18

> 32...65,535
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.
