How does the staircase lighting behave with bus voltage failure?
The behaviour at bus voltage failure is determined by the parameter Reaction on bus voltage failure
in the parameter window A:
How does the staircase light behave with bus voltage recovery?
The reaction at bus voltage recovery is defined by two conditions:
1. By the communication object Disable function time: If the staircase light is blocked after bus
voltage recovery, the staircase lighting can only be switched on or off via the communication
object Switch.
2. Using 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 communi-
cation object Switch.
Restart of staircase time after
end of permanent ON
Options: no
yes
•
no: The lighting switches off if Permanent ON is ended.
•
yes: The lighting remains on, and the staircase lighting time restarts.
The function of continuously ON is controlled via the Permanent ON communication object value. If
the communication object receives a telegram with the value 1, the output is switched ON irrespec-
tive of the value of the communication object Switch and remains switched on until the communica-
tion object Permanent ON has the value 0.
Note
Permanent ON only switches ON and "masks" the other functions. This means that the other
functions, e.g. staircase time or "pumping up", continue to run in the background but do not
initiate a reaction. After the end of permanent ON, the switching state, which would result without
the permanent ON function, becomes active.
