The Relative dimming telegram of all connected DALI devices is received via this communication object. They are dimming
telegrams BRIGHTER, DARKER and STOP. After a START telegram is received, the brightness value is changed in the
defined direction with the parameterized speed. If a STOP telegram is received before the dim process ends or the
maximum or minimum dimming value is reached, the dimming process is interrupted and the received brightness value is
retained.
If the dimming values are above or below the max. or min. dimming values (dimming thresholds), the respective dimming
threshold is set. If the dimming values are above or below the max. or min. dimming values (dimming thresholds), the
respective dimming threshold is set.
The dimming thresholds on the individual lighting groups continue to apply.
Resulting for the DALI functionality (dimming step 200 ms), the step-by-step dimming rarely used in KNX is only
conditionally supported. A small KNX dimming step can trigger a larger DALI dimming step under certain conditions.

This communication object is enabled if in
with the option yes.
Using this communication object, a lamp fault can be sent or read.
Telegram value
Using the communication object Fault lamp (Gx Group), the state of the lamps for every lighting group can be indicated.
Using the communication object (Diagnosis, No. 6) it is possible to request the lamp state for each DALI device.
It is possible to parameterize whether the fault is sent on after a change and/or after request.
Function
Relative dimming
Fault lamp
0 = no lamp fault
1 = lamp fault
(at least one connected DALI device has sent a lamp fault)
Note
This function must be supported by the DALI devices.
If DALI devices are used, which do not monitor their lighting equipment and which thus do not provide this
information on the DALI, the DLR/A will also be unable to detect a lamp fault. In order to monitor a lamp
fault, the function Detect ballasts does not need to be explicitly activated.
In most cases, a lamp fault is only determined or indicated by the DLR/A when the lighting equipment
should be switched on. For this reason, the DLR/A cannot report a fault beforehand.
