Commissioning

no - acknowledge is not necessary: As soon as the fault is remedied, the DLR/A will reset the fault
message, and it automatically sends the status change in dependence on the parameterization to the
communication object, e.g. Fault lamp. A telegram with the value 0 is sent. The change in the
malfunction state may take up to 45 seconds and depends on the number of connected DALI devices.

yes - acknowledgment required: First of all the communication object Acknowledge faults is enabled.
As soon as the fault is rectified, a telegram with the value 0 is not sent automatically. This fault signal
remains set until the fault is rectified and the fault signal is acknowledged or reset via the
communication object Acknowledge faults. Only then does the corresponding communication object
send its value 0. This can be very useful with the detection of sporadic faults or results.
