11.6.6 Exchanging the Solenoid Valve on Left or Right (and/or Cable)
WARNING
You might cut yourself on the blades and the tape deflector.
Never reach into the pneumatic cutter from below or into the empty-tape duct from above. 11
The cutter remains installed in the machine. 11
à Turn the machine and then the compressed air ON.
à Disconnect the movable component changeover table from the machine and move it out of the
machine.
à Turn the machine OFF, disconnect the machine from the mains and turn off the flow of com-
pressed air at the compressed air. Actuate the needle valve on the compressed air unit to bleed
the compressed air lines (see DANGER text in Section 11.1).

If the cable of the solenoid valve is faulty:
à Carefully undo the corresponding cable tie (left or right) on the outside of the control board
box (see Fig. 11.6.6 -> 10).
-> Do not damage the cables in this process.
à Remove the cover from the control board (see Fig. 11.6.6 -> 9).
à Unplug the plug-and-socket connection of the cable "Control board for tape cutter - valve"
of the appropriate solenoid valve on the control board (see Fig. 11.6.5 -> 1, 2).
à Loosen the plug-and-sockeet connection of the cable "Control board for tape cutter - valve"
of the appropriate solenoid valve (see Fig. 11.6.5).
à Take the cover off the cable pit (see Fig. 11.6.6 -> 5).
à Remove the cable and run the new cable "Control board for tape cutter - valve" (Item no.:
see Section 11.2). Push the excess lengths of cable into the cable pit.
à Make the plug-and-socket connection on the board (see Fig. 11.6.5) and on the solenoid
valve with correct allocation (see Fig. 11.6.6).
à Place the cover back on the control board (see Fig. 11.6.6 -> 9).
à Install the cover on the cable pit (see Fig. 11.6.6 -> 5).
à Use a cable tie to fasten the cables running to LH and/or RH side of the cable pit to the fixing
pedestal (on control board box).
The strain on the cable / plug-and-socket connections must be relieved (see Fig. 11.6.6 ->
8).
à Perform the appropriate “Final Steps” (see Section 11.6.11).
If the solenoid valve is faulty:
à Undo the 2 compressed air connections on the one-way restrictors at the faulty solenoid
valve (see Fig. 11.6.6 -> 1, 2, 6).
à Unplug the plug-and-socket connection of the cable "Control board tape cutter - valve"
on the faulty solenoid valve (see Fig. 11.6.6 -> 11).
à Undo the screws fastening the faulty solenoid valve (2 M3 screws: see Fig. 11.6.6 -> 4) and
remove the solenoid valve.
à Mount the new solenoid valve (Item no.: see Section 11.2) in the correct position, as shown
in Fig. 11.6.6. Make the plug-and-socket connection at the solenoid valve:
-> Tighten the screws to the correct torque -> see Table, Fig. 11.4.2.
-> The strain on the cable must be relieved (see Fig. 11.6.6 -> 8).
à Mount the short-stroke cylinder compressed air connections to the one-way restrictors on
the solenoid valve with the correct allocation (see Fig. 11.6.3 -> 6, 7, 8).
à Perform the appropriate “Final Steps” (see Section 11.6.11).
