Enable function lamp burn-in
object "Burn-in lamps" 1 bit
Option:
The DGN/S has the possibility for activation of the function Burn-in for all connected DALI devices.
Note
Continuous dimming of lamps, which are not burnt in, can mean that the maximum defined brightness of
the lamp may not be achieved, and the required brightness value in the area may not be achievable.
In order to guarantee the maximum lamp life and correct function of the ballast in the dimmed state,
some lamps (vapour filled) must be operated for a certain number of hours at 100 % brightness during
initial operation, before they can be permanently dimmed.
Detailed information should be taken from the technical data of the lamps.
no: The function Burn-in is not enabled.
yes: The function Burn-in is enabled. The communication object Burn-in lamps appears. At the same
time, two further parameters appear: Lamp burn-in period in hours [1..254] and Status of burn-in.
Response with activated function Burn-in
If a telegram with the value 1 is received via the communication object Burn-in lamps, the DGN/S
page 51, with the parameter Enable with function Burn-in (Object "Burn-in lamps").
During function Burn-in, the lighting group can only assume the state 0 % (OFF) or 100 % (ON).
Every device has its own "burn-in counter", which decrements when the device is switched on. The
counter has a counting interval of five minutes, i.e. if the lamp has been switched on for five min-
utes, the burn-in time is reduced by five minutes.
As every device of a lighting group has its own burn-in counter, the burn-in times of the individual
devices are determined even with overlapping groups. As soon as a device has completed its burn-
in time, it is enabled for normal dimming operation.
The internal burn-in counter has a size of 1 byte and provides a timer with five minute intervals and
a maximum value of 254 hours.

During burn-in only the lighting groups are considered that have been selected with the correspond-
