Commissioning
Enable communication objects:
"Acknowledge fault messages"
Options:
Should a fault occur (ballast, lamps, DALI, operating voltage), the DLR/S sends a telegram on the KNX
using the respective communication object (see
- Central,

No - acknowledgement is not required: As soon as the fault has been remedied, the DLR/S will reset
the fault message, and it automatically sends the status change, depending on the parameterization,
to the communication object, e.g. Lamp fault. A telegram with the value 0 is sent. The change in the
fault state may take up to 45 seconds and depends on the number of connected DALI devices.

Yes - acknowledgement is required: First of all, the communication object Acknowledge fault
messages is enabled. As soon as the fault is rectified, a telegram with the value 0 is not sent
automatically. This fault message remains set until the fault has been rectified and the fault message
is acknowledged or reset via the communication object Acknowledge fault messages. Only then does
the corresponding communication object send its value 0. This can be very useful with the detection
of sporadic faults or results.
"Fault controller supply voltage"
Options:

No: Failure of the light controller supply voltage is not reported to the KNX.

Yes: The communication object Fault controller supply voltage is enabled. As soon as the light
controller operating voltage has been interrupted, the communication object Fault controller supply
voltage sends a telegram with the value 1 on the KNX. The time at which a telegram is sent can be
adjusted using the following parameter:
No - acknowledgement is not required
Yes - acknowledgement is required
from page 53).
No
Yes
Send
Options: After a change
On request
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.
