Commissioning
Limit number of telegrams
Options:
The load on the KNX generated by the device can be limited with the limitation on the number of telegrams
sent. This limit relates to all telegrams sent by the device.

yes: The DLR/A monitors its sent telegrams and limits the telegrams sent in dependence on the
following two parameters, which appear via option yes:
Enable communication objects:
"Acknowledge faults"
Options:
Should a fault occur (ballast, lamps, DALI, operating voltage), the DLR/A sends a telegram on the KNX
using the respective communication object (see

no
yes
Time between two response telegrams
in s [1...255]
1...20...255
Options:
In period
50 ms/100 ms...1 s...30 s/1 min
Options:
This parameter defines the number of telegrams sent by the DLR/A within a period. The telegrams
are sent as quickly as possible at the start of a period.
Note
The DLR/A counts the number of telegrams sent within a parameterized period. As soon as the
maximum number of sent telegrams is reached, no further telegrams are sent on the KNX until
the end of the period. A new period commences at the end of the previous period. The telegram
counter is reset to zero, and sending of telegrams is allowed again. The current communication
object value is always sent at the time of transmission.
The first period (break time) is not predefined exactly. The period can be between zero seconds
and the parameterized time. The subsequent sending times correspond with the parameterized
time.
For example:
Maximum number of sent telegrams = 5, period = 5 s
20 telegrams are ready for sending. The DLR/A immediately sends 5 telegrams. The next 5
telegrams are sent after maximum 5 seconds. From this point, a further 5 telegrams are sent on
the KNX every 5 seconds.
no - acknowledge is not necessary
yes - acknowledgement is required
