﻿After starting the brightness sequence, the step-by-step run through the predefined brightness range begins. With each step, the effective brightness value is either increased or decreased depending on the configured sequence direction and transmitted as ARC power level on the DALI line. The number of steps and consequently the brightness value increment is derived from the total running time parameterised at this point.

A brightness sequence from 1% to 100% takes the specified time. The longer the total running time, the finer the brightness adjustment during the sequence and thus the resolution is. The brightness value increment is calculated by "100% : total running time [s]".

If the brightness range has been limited by setting a minimum brightness greater than 1% and a maximum brightness less than 100%, the effective running time of the brightness sequence is correspondingly shorter than the configured total running time.

The total running time exclusively defines the duration and the brightness value increment of a full brightness sequence. It does not specify a start or stop time. A sequence can be stopped before the total running time has elapsed.
