Using this communication object, the current state of the DALI Light Controller can be stored as the reference state.
In order to correctly detect a ballast fault, the DALI Light Controller 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 DALI Light Controller has received a detection telegram
with value 1 via this communication object. The DALI Light Controller notes the current system configuration as a reference
state. For this purpose, all DALI addresses are stored in the DALI Light Controller. Should a DALI address now be lost, e.g.
by a ballast fault, cable break, etc., this is interpreted by the DALI Light Controller as a ballast fault and sent on the KNX as
set in the parameterization. An automatic detection, e.g. after a KNX bus voltage recovery or light controller supply 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.

This communication object is enabled if in
Burn-in object "Burn-in lamp/status" is parameterized with the option yes. Furthermore, the function Burn-in must be
enabled in
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
with the parameter Enable function lamp burn-in object "Burn-in lamp". 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 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.

Alternatively, burn-in of an individual lighting group can be enabled via the communication object No. 37 Burn-in
lamp/status (group x). The communication objects Burn-in lamp/status (group x) and Burn-in lamp or Burn-in lamp/status
(DALI output) are independent of each other. The burn-in time of the lighting group is triggered or restarted with the value 1
on both communication objects.

Function
Detect ballasts
1 = start ballast detection
0 = no function
Note
This function can be triggered in manual mode using the S button. Furthermore, the detection of DALI
devices and saving them as a reference value is possible in the Software-Tool using the button Detect
ballasts.
