Function
The switching/shutter actuator receives telegrams from sensors or other controls via the KNX/EIB and
switches electrical consumers. The outputs of the actuator can be configured in the ETS either for the
shutter mode or alternatively for the switching mode, with mixed operation of the modes mentioned on the
device itself remaining possible. In shutter mode the switching/shutter actuator uses its relay contacts for
switching electrically operated blinds, shutters, awnings, venting louvers or similar devices for 230 V AC
mains voltage (4 channels) or extra-low voltage 12...48 V DC (2 channels). In the switching mode the
actuator switches electrical consumers such as lighting fixtures or also extra low voltages.
Each relay output is equipped with mains-operated monostable switching relays so that the preferred
contact positions are maintained also during bus voltage failure.
The controls (4 pushbuttons) on the front panel of the device permit switching the relays on and off by hand
in parallel with the KNX/EIB even without bus voltage or in a non-programmed state. This feature permits
fast checking of connected motors for proper functioning.
The functionalities that can be preset with the ETS independently for each output channel include in shutter
mode, for instance, separately parameterizable moving times, enlarged feedback functions, assignment to
up to five different safety functions, a sun protection function adapted to a great variety of requirements and
the incorporation into scenes or forced-position applications. Centralized control of all outputs is also
available. The functionalities in switching mode include among other things extensive timing functions, logic
operations, scenes, disabling or forced control functions and an enlarged range of response telegrams.
Centralized switching of all outputs is also available. Moreover, the preferred states of the relays in case of
bus voltage failure or bus / mains voltage return and after ETS programming can be preset separately.
For project design and commissioning of this device it is recommended to use the ETS3.0d. The
advantages with regard to downloading (shorter loading times) and parameter programming are available
only if this new ETS patch version or later versions are used. For the ETS2 and older versions of the ETS3
a separate product database is available.
The switching/shutter actuator has its own mains supply independent of the connected drives or loads. For
actuation of the outputs, the mains supply must always be on. The device electronics are supplied from the
bus voltage or from the mains voltage. The device is designed for being mounted on DIN rails in closed
compact boxes or in power distributions in fixed installations in dry rooms.
