Lamp burn-in time in hours [1...255]
Options: 1...100...255
This parameter defines the time period for the Burn-in function. Until this time has elapsed,
the ballast/group can only be operated at 100% and OFF on the DALI output, i.e. at every set
brightness value other than 0%, the lamp is switched on at 100% brightness.
Once the burn-in time has run or the Burn-in function is deactivated, e.g. if a telegram with
the value 0 is received via the Burn-in lamp group object, the lamp can be dimmed as usual.
The burn-in time is only counted if a DALI device is connected to the output, ready for operation
with a supply voltage, and switched on.
The burn-in time function remains activated in the event of a KNX bus voltage failure. The time is
not lost but stops counting during the failure.
With a gateway supply voltage failure, the remaining burn-in time is saved and reused after
gateway supply voltage recovery. This also applies after an ETS download.
Reaction with activated Burn-in function
If a telegram with the value 1 is received via the Burn-in lamp group object, the gateway
activates the Burn-in function and sets the programmed burn-in time. The function can also
be activated with the i-bus
During the Burn-in function, the lamp can only adopt 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 minutes, the burn-in time is reduced by five minutes. 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 timer with five-minute intervals and a maximum value of
255 hours.
Reaction on KNX bus voltage failure and gateway supply voltage failure
The elapsed burn-in time is retained and continues to count down after KNX bus voltage
recovery and gateway supply voltage recovery.
