Content of communication object
Option: Fault lamp
Fault ballast
Fault lamp or ballast
This parameter determines the equipment fault, which is provided on the enabled communication
object.

Fault lamp: The communication object Fault lamp is enabled. Using this communication object,
it is possible to provide information on whether the lighting group of a lamp has failed on the
KNX. Should there be a fault, the communication object Fault ballast is written with a 1 and
sent on the KNX in dependence on the parameterization set beforehand.

Fault ballast: The communication object Fault ballast is enabled. Using this communication
object, it is possible to provide information on whether the lighting group of a ballast has failed
on the KNX. Should there be a fault, the communication object Fault lamp is written with a 1
and sent on the KNX in dependence on the parameterization set beforehand.

Fault lamp or ballast: The communication object Fault lamp or ballast is enabled. Using this
communication object, it is possible to provide information on the KNX relating to a lamp failure
or a ballast failure in the lighting group.
Note
In order to correctly detect a ballast fault, the function Detect ballasts must be activated in the
DALI Light Controller. With this function, the DLR/A notes the exact number of DALI devices and
the DALI address of the individual DALI devices currently connected to the DLR/A for reference
purposes. If the determined number of DALI devices does not correspond with the referenced
number of devices or if a DALI address has disappeared, this is evaluated as a ballast fault and
displayed on the KNX using the communication object, as dependent on the sending
parameterization.
The function Detect ballasts can be triggered either via the communication object Detect ballasts
or by pressing the S button when in manual mode. Alternatively, this function can also be
performed during the DALI group assignment phase in the Software Tool.
