Behaviour in case of bus
voltage failure
close contact
open contact
no reaction
The actuator permits setting the preferred relay
contact position in case of bus voltage failure
separately for each output.
The relay contact is closed on bus voltage
failure.
The relay contact is opened on bus voltage
failure.
In case of bus voltage failure, the relay of the
output shows no reaction and remains in the
switching state last selected.
Behaviour after bus or
mains voltage return

state as before bus

(if parameterized)
The actuator permits setting the preferred relay
contact position after bus voltage return
separately for each output.
The relay contact is closed after bus voltage
return.
The relay contact is opened after bus voltage
return.
After bus voltage return, the switching state last
selected before bus voltage failure and
internally stored on bus voltage failure will be
retained.
The staircase lighting function is activated after
bus voltage return independent of the
"Switching" object. For this setting it is
indispensable that the staircase lighting function
has been programmed and enabled
beforehand. When the staircase function has
not been enabled, this setting will produce no
reaction after return of the bus voltage.
Setting "state as before bus/mains voltage
failure": an ETS application or parameter
download resets the internally stored
switching state to "off – 0".
The device adopts the parameterized
behaviour only if the last ETS programming
of the application or of the parameters ended
at least ca. 20 s ago. Otherwise (T
ETS
< 20 s),
the "Behaviour after ETS programming" will
be adopted also in case of bus voltage return.
The parameterized behaviour will only be
adopted, if no forced control is activated after
bus voltage return.
