The function Staircase lighting is triggered by an ON telegram to the communication object Switch of a
lighting group. With an OFF telegram, the lighting group is controlled with the basis brightness of the func-
tion Staircase lighting. The function Staircase lighting remains in standby mode and is started by a re-
newed ON telegram. Should the DGN/S receive a renewed ON telegram during ongoing function Staircase
lighting, the function Staircase lighting is restarted (retriggered).
The function Staircase light is also started if the DGN/S receives a telegram with the value 1 on the com-
munication object Activate fct. Staircase lighting or Act. Staircase lighting/status.
If in the following the communication objects Switch (ON telegram) or Brightness value are mentioned, it
also applies for the communication objects Switch/status or Brightness value/status.
Time for dimming up (soft start)
in s [0...65,535]
Options:
This parameter determines the time duration, in which the DGN/S dims to the brightness value for the
staircase time. The function Staircase lighting is switched on with a soft start.
Staircase lighting time
Options:
This parameter determines whether the staircase light is automatically shut off after a programmable time
or whether a brightness value is applied. The function Staircase lighting is no longer switched off automati-
cally after Gateway supply voltage recovery.
limited: The staircase lighting time is ended after a certain time, which can be set with both the follow-
ing parameters.
unlimited: The function Staircase lighting is no longer switched off automatically. The brightness value
is changed only if a new telegram is received via the KNX or by forced operation, e.g. with a fault whe-
re the brightness value is changed.
Time duration in s [0...65,535]
Options:
This is the time duration, for which the function Staircase lighting remains switched on for the light-
ing group.
Time duration changeable via
obj. "Flexible time" 2 byte
Options:
The time received via the communication object Flexible time has an effect on the time duration of
the staircase lighting. The flexible dimming time has a value between 0...65,535 seconds.
