Commissioning
Dim period to reach set brightness
value (function Brightness value)
Options:
This parameter determines the time duration used by the lighting group to achieve the brightness value
received via the communication objects Brightness value or Brightness value/Status.

Jump to: All the devices of the lighting group immediately switch ON with the received brightness
value.

0.7 s...90.5 s: During this time, the lighting group is dimmed down to the received brightness value.

Flexible dimming time – settable via KNX: The time received via the communication object Fade time
(DALI format) or (KNX format) has an effect on the ON/OFF dimming via the brightness value. There
are 16 discreet values which are defined according to DALI for the Flexible time for dimming. If the
KNX format is selected for the Flexible dimming time, rounding off errors can occur as a result of
discreet DALI times.

Enable function Lamp burn-in object
"Burn-in lamp"
Options:
This parameter defines whether the lighting group should be considered when the Burn-in function is
activated. Lighting equipment, e.g. incandescent bulbs, which does not require a burn-in phase can be
excluded from the burn-in process. They can always be dimmed independently of the function Burn-in.
The Burn-in function is enabled in the
function Burn-in, every lighting group can be burnt-in individually via the additional communication object
Burn-in lamps/Status. The additional communication object is selected in the
Gx Functions, page 86, under the additional objects.

Yes: The lighting group is considered during an active Burn-in function and, during the burn-in phase,
it can only be switched off with 0 % brightness (OFF) and on with 100 % brightness (ON).

No: The lighting group is not taken into consideration during an activated Burn-in function and can
also be dimmed during an activated Burn-in function.
