In this parameter window the parameters for dimming of the lighting are set.
With the object Relative dimming the lighting is dimmed brighter or darker,
see Communication objects.
Dimming speed 0...100 %
in s [0...65,535]
Options: 0...6...65,535
A dimming ramp is defined by the dimming speed.
The dimming ramp is the parameterised time, during this time
the Light Controller achieves the value between 0 % and 100 %.
Note
The dimming speed refers to a full, unlimited dimming range, i.e. at
a minimum > 0 % or maximum < 100 % dimming value, the dimmer
quickly reaches the maximum dimming value.
Maximum dimming value
Options: 100/99...51/50 %
With this parameter the largest brightness value is set which can be
controlled with the Light Controller via relative dimming. In this way,
the service life of fluorescent lighting can be extended or energy can
be conserved.
If the brightness value is above the upper dimming value, e.g. by recall of
a preset or a scene, it is only possible to reduce the brightness.
The dimming values do not just apply for dimming but also for the switching
and staircase lighting function. During slave operation, when setting a
brightness value and when recalling a scene or preset, the value limits
which are parameterised in the parameter window
The dimming value is independent of the value or control limit.
