Commissioning
Reaction on KNX bus voltage failure and gateway voltage failure
The elapsed burn-in times are retained and continue to count after KNX voltage recovery and ga-
teway operating voltage recovery. The burn-in process is restarted by a telegram with the value 1 to
the communication object Burn-in lamps or Burn-in lamps/status.
This telegram has an effect on all lighting groups, for which the function Burn-in has been param-
eterized. A telegram with the value 0 sets the burn-in counter to 0 and ends function Burn-in for all
lighting groups.
Lamp burn-in period in hours [1...254]
Options: 1...100...254
This parameter determines the time period for function Burn-in. As long as this time has not elap-
sed, the DALI device can only be operated with 100 % and OFF on the DALI output, i.e., at every
set brightness value not equal to 0 %, the lamp is switched on with 100 % brightness.
After the burn-in time has elapsed or the function is deactivated (received telegram with the value 0
via communication object Burn-in lamps), the DALI device can be dimmed as usual.
The burn-in time is only counted if a DALI device is connected to the DALI output and is supplied
with voltage ready for operation.
The function of the burn-in time remains activated with a KNX bus voltage failure. The time for the
switched on lamps continues to count down (decrement).
With a gateway operating voltage failure, the remaining burn-in time is saved and reused after Ga-
teway operating voltage recovery. This also applies after an ETS download.
Status of burn-in
Options: no
yes: via object "Burn-in lamps/status"
The DGN/S features the option of sending the status of the function Burn-in on the KNX via com-
munication object Burn-in lamps/status.
no: No status message is sent for the function Burn-in.
yes: The communication object Burn-in lamps changes to Burn-in lamps/status. If this commu-
nication object receives an ON telegram, the function Burn-in is started and the status is sent
on the KNX. Two further parameters appear:
send object value
Options: after a change
after request
after a change or request
after a change: The status is sent after a change.
after request: The status is sent after a request.
after a change or request: The status is sent after a change or a request.
