Reaction after bus voltage failure, bus or mains voltage return or after ETS programming
The preferred relay contact positions in case of bus voltage failure, bus or mains voltage return or after ETS
programming can be preset separately for each output. since the actuator is equipped with mains-
dependent monostable relays, the relay switching state at bus voltage failure can be defined as well.
Presetting the behaviour after ETS programming
The parameter "Behaviour after ETS programming" can be preset separately for each output channel on
the parameter page "Ax - General" (x = number of output). This parameter can be used to parameterize the
output relay behaviour independent of the behaviour after bus voltage return.
Set the parameter to "no reaction".
After ETS programming, the relay of the output shows no response and remains in the switching state
last selected. The internal logic switching state is not lost either by an ETS programming cycle.
Set the parameter to "close contact".
The relay contact is closed after an ETS programming cycle.
Set the parameter to "open contact".
The relay contact is opened after an ETS programming cycle.
The parameterized behaviour will be executed after every application or parameter download by the ETS.
Downloading only the physical address or programming the group addresses only partially has the effect
that this parameter will be disregarded and the parameterized "Behaviour after bus voltage return be
adopted.
A programming operation with the ETS can be performed when the bus voltage is connected to the
switching/shutter actuator and activated. The mains supply is not needed for an ETS download.
During every ETS programming operation, the switching/shuter actuator always opens the relay contacts
for all outputs. For this reason, a closed relay contact may open briefly even if the output is set to "no
reaction".
A switching state set after an ETS programming cycle will be tracked in the feedback object depending
on the "Mode of operation" parameter.
An active manual mode will be terminated by an ETS programming operation.
After an ETS programming operation, the disabling functions and the forced-control positions are always
deactivated.
