Using this communication object, the current state for the DGN/S can be stored as the reference state.
In order to correctly detect a ballast fault, the DGN/S must have correctly identified all connected DALI devices and thus know
the number of connected DALI devices to be monitored. This identification process runs autonomously and fully automatically
in the background, after the DGN/S has received a detection telegram with value 1 via this communication object. The DGN/S
notes the current system configuration as a reference state. For this purpose, all DALI addresses are stored in the DGN/S.
Should a DALI address now be lost, e.g. by a ballast fault, cable break, etc., this is interpreted by the DGN/S as a ballast fault
and sent on the KNX as set in the parameterization. An automatic detection, e.g. after a KNX voltage recovery or Gateway
operating voltage recovery, does not take place.
The detection should be carried out directly after commissioning or when extending or reducing the DALI devices. The DALI
devices are continually monitored, regardless of whether the lamp is activated or deactivated. The DALI devices must be
installed properly and supplied with operating voltage if necessary.

Note
This function can be manually triggered if the button
seconds. Furthermore, the detection of DALI devices and saving as a reference value is possible in the
DALI-Software-Tool via the button Detect ballasts.

This communication object is enabled if in
object "Burn-in lamps" 1 Bit is set with the option yes.
Using this communication object, the function Burn in is activated or deactivated for protecting the ballast and the lamp. After
receiving a telegram with the value 1, all lighting groups intended for burn-in can only be controlled with 0 % (OFF) or 100 %
brightness. Whether a lighting group is considered during burn-in is set in the
parameter Enable with burn-in function (Object "Burn-In lamps"). Incoming telegrams have an effect on all lighting groups
which are intended for burn-in purposes.
The time duration for burn-in is defined commonly for all lighting groups. 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 lamps 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.

Simulation of DALI values running in background. It will be set with end of burn-in.
