"Ballast fault"
Options:
Using this communication object, a ballast fault can be sent or read. Using this communication object, a
ballast fault can be sent or read.

No: The communication object Ballast fault is not enabled.

Yes: The communication object Ballast fault is enabled. As soon as there is a ballast fault on the
output, it is indicated by a 1 in the communication object Ballast fault.
Note
In order to detect the fault of a ballast correctly, the DLR/S must have correctly identified all connected
DALI devices and thus know the addresses to be monitored. This identification process can be triggered
via the communication object Detect devices or by the S button in manual mode. An automatic Detect
devices, e.g. after a KNX voltage recovery or light controller operating voltage recovery does not take
place. After approx. 90 seconds, all the DALI devices are detected and the failure of a ballast can be
correctly established. Not just the number of ballasts are considered, but also the DALI addresses. If a
DALI device has failed and has been replaced by a DALI device with another address, a ballast fault will
still be indicated. The ballast fault is only remedied after a new DALI device has received the address of
the DALI device that has malfunctioned.
The activation 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 active or not active. The
DALI devices must be installed properly and supplied with operating voltage.
If all the DALI devices of a lighting group are no longer recognized by the DLR/S, e.g. all ballasts have
failed, the status values of the lighting group are reset as follows:
Brightness value to 0,
Switch state to 0 (OFF)
and any existing lamp fault is reset, as a statement of the state of the lighting group is no longer
possible.

After a change or request

After a change: The status is sent via the communication object after a change.

On request: The status is sent after a request by the communication object Request status
values.

After a change or request: The status is sent via the KNX when the status changes or the
status is requested via the communication object Request status values.
