How does the staircase lighting react on bus voltage failure?
Reaction on bus voltage failure is determined by the parameter Contact position on bus voltage
failure in Parameter window B: Output , p.55.
How does the staircase lighting react on bus voltage recovery?
Reaction on bus voltage recovery is defined by the following conditions.

By the parameterization of the communication object Switch . Whether the staircase lighting is
switched on or off with bus voltage recovery depends on the programming of the communica-
tion object
Switch .
If the staircase lighting time is interrupted by a bus voltage failure or by a download, it will continue
afterwards.
After bus voltage failure this only applies if no other reaction has been parameterized.
