Electrical installation
9.5.2 connection with multi-pole cable and
ribbon cable terminal
As an alternative to the bus connection model with 4-pole circular
plug, there is the control head with multi-pole cable (M12 circular plug)
and ribbon cable terminal. The wiring diagram of the circular plug cor-
responds to the bus connection of the M12 4-pole circular plug and
can easily be connected to the ribbon cable terminal (see “Fig. 17”).

handling the ribbon cable terminal
The multi-pole cable features a ribbon cable terminal - with M12 plug-in
connector branch circuit - for AS-Interface cable harness. The ribbon
cable terminal contacts the AS-Interface cable harness by means of
penetration technology which allows installation by “clipping in” the AS-
Interface cable harness without cutting and without removing insulation.
procedure:
→
Open the ribbon cable terminal
(loosen screws and remove cover)
→
Insert cable harness conclusively
→
Close ribbon cable terminal again
→
Tighten screws
Slightly undo thread-forming screws
(approx. 3/4 turn to the left) and position them on the existing
tapped bore and screw in.
The teach function can now be used to automatically determine
and read in the end positions of the valve (description of the teach
function see chapter “10 Teach function”).
For the bus variant AS-Interface, the teach function can also
be started via the bus protocol.
