How does the staircase light 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: Output.
How does the staircase light behave with bus voltage recovery?
The reaction at bus voltage recovery is defined by two conditions:
A By the communication object Time function disable. If the
staircase lighting is disabled after bus voltage recovery, the
staircase lighting can only be switched on or off via the
communication object Switch.
B Using the parameterization of the communication object Switch.
Whether the light is switched on or off with bus voltage recovery
depends on the programming of the communication 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 irrespective of
the value of the communication object Switch and remains switched
on until the communication 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 that would result
without the permanent ON function becomes active.
