Behaviour in case of bus voltage failure, after bus or mains voltage return or after programming
with the ETS
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 define the output
relay behaviour independent of the behaviour after bus or mains voltage return.
Depending on the selected mode of operation, the ETS adapts the designations of the parameter settings
("raising"
↔
"opening the louver" / "lowering"
↔
"closing the louver")
Set the parameter to "stop".
After programming with the ETS, the actuator switches the relays of the output to the "stop" position and
a travel movement in progress is stopped.
Set the parameter to "raising" or "opening the louver".
After programming with the ETS, the actuator raises the curtain or opens the venting louver.
Set the parameter to "lowering" or "closing the louver".
After programming with the ETS, the actuator lowers the curtain or closes the venting louver.
At the beginning of each ETS programming cycle, the switching/shutter actuator always executes a "stop"
command for all outputs. The manual mode, if active, will be terminated.
The "Behaviour after ETS programming" as parameterized will be executed after every ETS application
or parameter download. A simple download of the physical address alone or partial programming of only
the group addresses has the effect that this parameter is disregarded and that the parameterized
"Behaviour after bus or mains voltage return" will be executed instead. For outputs with end position
detection also the travelling times learnt will be retained in this case.
Programming with the ETS is possible when the bus voltage line is connected to the switching/shutter
actuator and the bus voltage supply is on. An ETS download does not require the mains voltage supply to
be on. If programming with the ETS was performed with bus voltage only, the parameterized "Behaviour
after ETS programming" will only be executed when also the mains voltage supply of the actuator has
been switched on. The "Behaviour after bus or mains voltage return" will not be activated in this case !
This reaction must be taken into account especially with actuators that are installed in pre-programmed
condition into an existing electrical installation.
After programming with the ETS, the safety functions, the forced positions and the sun protection
function are always deactivated.
