System failure level
This variable specifies the lamp power that the DALI device is to adopt in the event of a system error.
MIN level
You specify the minimum lamp power that the DALI device is to adopt here, so that the illuminance does not
fall below a level that you want. The MIN value cannot be less than the smallest physically possible value
[} 33]specified by the manufacturer of the DALI device.
MAX level
You specify the maximum lamp power that the DALI device is to adopt here, so that the illuminance does not
exceed a level that you want.
Fade rate
Enter the velocity in steps per second (step/s), with which the DALI device dims for 200 ms when the
commands Brighter [} 29] (DALI command 1 [} 53]
issued. The absolute fade rate is not entered directly, but it is calculated according to the following formula:

Fade time
Enter here the time in seconds that the DALI device is to take to change the brightness when, for instance,
changing a scene, or to execute direct DALI commands for lamp power. This time is independent of the size
of the change, so that all the lamps complete their change over the same period. In the case of a lamp that is
switched off, the pre-heating and ignition time is not included in the fade time.
The absolute fade time is not entered directly, but it is calculated according to the following formula:
