Staircase lighting time
Options:
This parameter sets the staircase lighting time, i.e. how long the group is controlled with the staircase
lighting brightness. The dimming up and dimming down times are not included.
•
0...65,535 s: During this time the group is controlled at the staircase lighting brightness.
Staircase lighting will switch off after
reaching basic brightness (advance warning)
Options:
This parameter defines whether the staircase lighting switches off at the turn off brightness or via a basic
brightness.
•
Yes: Before switching off the lighting dims to the basic brightness over a parametrized dimming time.
Only at this point does it switch off at the turn off brightness. If no turn off brightness has been set, it
switches OFF (0% brightness value).
•
No: The lighting switches to the turn off brightness over a parametrized dimming time. If there is no
turn off brightness set for the group, the lighting switches off (0% brightness value).

Options: 0...2...65,535 s
This parameter can be used to set a soft stop for the staircase lighting by defining how long it takes
for the group to set the staircase lighting to the turn off value. The turn off value must not be 0.
Note
The turn off brightness applies to the group, including the additional function.
Therefore it is parametrized in the X group Group x parameter window.
There is also an option to activate or deactivate the turn off brightness for the whole
output using the Activate fct turn off brightness group object.
Whether the group evaluates the Activate fct Turn off brightness group object is
parametrizable for each group.
