Parameter window A: Dimming
This parameter window is shown if the corresponding function was enabled in
A:
General, p. 26.
The function Dimming enables you to use additional options that are primarily used to dim output voltages.
To set these additional options, use the parameters below.
If the function Characteristic is in use at the same time, certain values are also dimmed by means of the
parameterized characteristic.
In addition, when the function Dimming is in use, it activates the 4-bit input group object Dimming and the
1-bit input group object Switch plus the 1-bit output group object Status Switch.
Rel. dimming speed for [0...100] and
input value in s [0...255]
Options:
The value selected indicates the dimming speed required to dim from 0 to 100 %. If dimming between
other values, the duration is calculated based on this value.
Note
The dimming range can be limited only absolutely using the characteristics, whereby the upper and
lower limits serve as the upper and lower dimming limits.
Note
The lower dimming limit should be set to a value at which the lamps can still be operated. Some lamps
switch off or start to flicker at a value below around 10% (please observe the manufacturer's technical
data).
