With this communication object, it is possible to disable the fault messages (lamp or ballast fault) of the DLR/S. If the fault
messages are disabled, the DLR/S will continue to undertake fault message examination regarding lamp and ballast faults.
During the inhibit, the faults are evaluated but not sent on the KNX. The values of the communication objects are also not
updated.
The latent time of the system can be minimized at low KNX load when the fault messages are inhibited.
When all fault messages are enabled, the malfunctions will be sent in accordance with their parameterization. If a fault still
exists after enabling of the fault message, this fault is recorded and the information is sent on the KNX in accordance with
the parameterization.

This communication object is always enabled.
Using this communication object, you indicate if the system state does not correspond with the state in the DALI Light
Controller, i.e., there are differences between the group and scene assignments stored in the DLR/S when compared to the
information stored in the DALI devices. This can, for example, be the case if exchanged or pre-programmed DALI devices
with group assignments are installed on the DLR/S.

Function
Disabel send. of fault message
0 = Enabling of fault messages (lamp and ballast fault)
1 = Disabling of fault messages (lamp and ballast fault)
Note
This function can, for example, be useful for systems with emergency lighting applications for daily checking
of the lamps of the DALI devices by the DALI control line, and thus disconnect them from the DALI master
(DLR/S). In this case, the DLR/S detects the loss of the DALI device and sends a ballast fault, even though
this is a normal operating state. Should the fault message be disabled before separation from the DALI
control line, no fault is reported by the DLR/S. Operation can continue as normal. After checking the lighting
equipment, normal monitoring can be reactivated via the fault message communication object Disabel send.
of fault message.
Conflict DALI
0 = There is no DALI conflict, i.e. the state (groups and scenes) matches the information stored
in the DLR/S.
1 = There is a DALI conflict
