Project design and programming
This function is visible if the parameter "Select extra function" in the
"General" parameter window has the value "Staircase lighting function".
On receipt of the telegram value "1" at the object "Telegr. switch", the lighting
is switched on. Once the staircase lighting time t
is dimmed down to the lower dimming limit during an adjustable dimming
down period t and then switches off. The lower dimming limit from the
D
parameter window "A: Dimming" is adopted.
Behaviour of the "Staircase lighting function" during and after voltage
failures:
Bus voltage failure
Bus voltage recovery

The staircase lighting function is deactivated.
Status of the staircase lighting function is restored. If
the staircase lighting was switched on or is in the
dimming down period, the staircase lighting time is
restarted (normal staircase lighting time). 'Pumping'
is not taken into account.
