How does the staircase lighting react on bus voltage failure?
Reaction in the event of bus voltage failure is specified by the parameter Contact position on bus
voltage failure in parameter window H: Output.
How does the staircase lighting react on bus voltage recovery?
Reaction on bus voltage recovery is defined by two conditions.
1. By the communication object Disable function time. If staircase lighting is disabled after bus
voltage recovery, it can only be switched on or off via the communication object Switch.
2. By the parameterization of the communication object Switch. Whether the light is switched on
or off on bus voltage recovery depends on the settings of Switch.
