Planning and application
A telegram with the value 0 which is received by the object Activate
staircase function deactivates the staircase function. Thereafter, the device
operates like a "normal" switch/dimming actuator, i.e. all other functions such
as relative dimming, setting of a brightness value and the scene and preset
functions can be fully used again.
For renewed activation of the staircase light function a telegram with the
value 1 must be received on the object.
With switched on staircase lighting the maximum and minimum dimming
values, as defined in parameter window
The respective parameterized values are set with overshoot or undershoot.
Option: yes (retriggerable):
Diagram staircase lighting time
After the staircase lighting time T
automatically. With each telegram 1 the time restarts ("retrigger function"),
if the parameter Extending staircase lighting by multiple operation (pumping
up) is set to yes in the parameter window
(retriggerable)
In this example, a dimming with the corresponding prewarning is
parameterised. The prewarning is visualised by the dimming.
At the same time, the object Warning staircase lighting can be switched
as a project-specific warning (e.g. optical or acoustic warning).
