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 Block staircase light.
If the staircase light is blocked after bus voltage recovery,
the staircase light can only be switched ON or OFF via the
communication object Switch.
B By the parameterisation of the communication object Switch.
Whether the light is switched ON or OFF with bus voltage
recovery depends on the programming of the Switch
communication object.
Enable communication object
"Permanent ON" 1 bit
Options:
no
yes
yes: The communication object Permanent ON is enabled.
If the communication object Permanent ON is assigned 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. After ending the Permanent ON state the
staircase will react as defined in the following parameters.
Example
This communication object can be used for example to allow the caretaker
or maintenance and cleaning personnel to initiate a permanent ON.
The following parameter is visible if in parameter Enable communication
object "Permanent ON", 1 bit the option yes has been selected.
Restart of staircase time after end of
permanent ON
Options:
no
yes
yes: The lighting remains on and the staircase lighting time
restarts.
no: The lighting switches off if Permanent ON is ended.
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.
