object "Burn-in lamp" for the lighting group.
Via additional communication object Burn-in lamp/status, the lamps of the lighting group can be burned in individually.
Furthermore, it is possible to burn-in the lighting group together with the other lighting groups via the communication object
Burn-in lamp (No. 26) of the DALI output.
Burn-in is initiated by a telegram with the value 1. The lighting group can only be controlled with 0 % (OFF) or 100 %
brightness.
After this burn-in time has elapsed, the lighting group can be dimmed as usual, and the programmed light scene can be
recalled.
If a telegram with the value 1 is received on the communication object Burn-In Lamp during the burn-in time, the period
restarts from the beginning.
A telegram with the value 0 deactivates the function Burn-in and enables "normal" operation. The burn-in time is only
counted if a ballast on the DALI output is connected and supplied with power. The burn-in time counts in five minute steps.
The burn-in time is not lost via KNX bus voltage failure, light controller supply voltage failure or download.

For further information see:
Alternatively, the burn-in of all lighting groups can be initiated via the communication object Burn-in lamp (No. 26) of the
DALI output. The communication objects Burn-in lamp/status of the DALI output and group x are independent of each
other. The burn-in time of the lighting group is initiated by a telegram with the value 1 or reset with the value 0. This is
independent of whether the telegram is received via the lighting group x communication object or the DALI output.

This communication object is one of the additional communication objects that can be selected in
Functions, page 82.
The communication object is used for blocking a DALI output to prevent unwanted operation. Further incoming telegrams
are ignored and not evaluated in the background. The incoming telegrams will only be evaluated after a renewed release of
the lighting group. The lighting remains unchanged when a block is removed.
A block during the staircase lighting or control function on the other hand leads to an immediate blocking of the DALI output
and freezing of the brightness value. After unblocking, the function Staircase lighting continues with dimming (prewarning).
If the functions Lighting control or Slave were active before the block, they will be re-established.
The Block function has a lower priority than forced operation; refer to the
After KNX bus voltage recovery or download, the blocking is removed and must be reset if required.
