Minimum brightness value
Options: 50/49...20...1/0,3 %
This parameter defines the minimum brightness value, which can control
the output via a brightness telegram.
If the Light Controller receives a brightness value less than the minimum
brightness value, the minimum brightness value is set.
The smallest minimum brightness value has a value of 0.3 %, thus a switch
off is always possible at the parameterised minimum dimming value.
The value limit which is used to set a brightness value with the preset and
scene function is considered. The limit in slave operation is also active here.
The control limit is active during the constant lighting control.
If a brightness value is recalled, which is less than the minimum brightness
value, the lower brightness value is set.
The limit value is independent of the:
•
Dimming value which is parameterised in the parameter window
and which applies for the dimming, switching and
X: Dimming
staircase lighting function.
•
Control limit which is parameterised in the parameter window
and which applies during lighting control.

Allow switching on via brightness values
Options: no
yes
This parameter determines if switched off lighting can be switched on
by a brightness value telegram greater than 0.
Allow switching off via brightness value
Options: no (stop on minimum brightness values)
yes
If a brightness value of 0 is received, you can set here if the lighting is
switched off (yes) or if they remain at the minimum value limit.
If a brightness value is received during a dimming process, the dimming
process is stopped and then a new brightness value is implemented.
Note
The reaction of the Light Controller with activated light control is
parameterised in the parameter and
