- General information
Dynamic administration of group addresses
Maximum no. of group addresses and associations: 152
Device selection:
L L
The application must first be adapted to the hard-
ware in use. When changing over the device selec-
tion, parameter settings and linked group addresses
are modified by the ETS program. For this reason, the
device selection should be set before configuring
the device.

Function
When the application is loaded, the following functions can
be implemented and controlled via the bus:

With regard to the switching behaviour of the actuator,
each function has a certain priority. The weighting of the

Behaviour on bus voltage failure/reset
- Behaviour on bus voltage failure
When the bus voltage drops below 18 V, the relay can
adopt a parameterised state. The relay can either be closed,
opened or remain in the position it occupied prior to the
failure. At the same time, the current switching position of
the relay is stored in the device. Only the actual relay state
(“1” for closed; “0” for opened) at the time of the voltage
failure is saved and not any active time delays. No further
status response telegrams are sent. This function has the
highest priority.

- Behaviour on bus voltage recovery
On bus voltage recovery, the relay can adopt a parameter-
ised state. The following options are available for selection.
In the settings “opened” or “closed”, the relay contact is
opened or closed. An inversion does not take place in the
“break contact” relay mode.
Staircase lighting functions: In the “make contact” mode,
the staircase lighting function starts with the setting
“closed”. This also happens in the “break contact” mode with
the setting “opened”.
In the setting “no change”, the relay remains in the current
state. Any manual operation that occurs in the meantime
(with 2-gang and 4-gang switch actuators) is retained. The
device does not know the status of the channel at this point
and therefore no status signal can take place. The status is
only available following a switching action of the channel.
In the setting “as for bus voltage failure”, the relay adopts
the state which was stored in the device on bus voltage
failure. Any manual operations that occur (with 2-gang
and 4-gang switch actuators) are overwritten. There are no
stored states once the application has been downloaded.
This means that the output is opened in the “make contact”
mode while the relay closes in the “break contact” mode.
If the setting “flash” is selected, the relay starts to flash on
bus voltage recovery. The flashing interval can be set.
