Using this communication object, the current state of the DALI Light Controller can be stored as the reference state.
In order to detect a ballast fault correctly, the DALI Light Controller must have correctly identified all the 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, the 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 according to the parameterization. Automatic detection, e.g. after a KNX voltage recovery or light controller 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 observed, 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 the
Burn-in object "Burn-in lamps / Status" is parameterized with the Yes option. Furthermore, the Burn-in function must be
enabled in the
Using this communication object, the Burn in function is activated or deactivated to protect the ballast and the lamp. After
receiving a telegram with the value 1, all the 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
page 67, with the parameter Enable function burn-in object "Burn-in lamps". Incoming telegrams have an effect on all the
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 scenes can be recalled. If another 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 Burn-in function 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 triggered via the communication object Burn-in lamps group x
(no. 37). The communication objects Burn-in lamps/Status (group x), Burn in lamps and Burn-in lamps/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 devices
1 = Start device detection
0 = No function
Note
This function can be triggered in manual mode using the S button. Furthermore, DALI devices can be
detected and saved as a reference value in the Software Tool using the Detect devices button.
