The cutter remains installed in the machine.

X Turn the machine and then the flow of compressed air ON.

X Disconnect the movable changeover table from the machine and move it out of the machine.

X Turn the machine OFF,

X Remove the cover from the control board.

X Carefully undo the cable ties (15) (left and right) on the outside of the control board box.

 -> Do not damage the cables in this process.

X Mark the allocation of all press-fit connections and disconnect all press-fit connections from the

control board.

X Disconnect the control unit (box) from the support bar by pushing both of the spring-mounted

elements away from the ba.

X Carefully insert the new control unit onto the rail, in the correct rotary position and location, until it

locks into place.

4-39: Control Unit

X Mount an adhesive fixing pedestal for cable

ties on the outside LH and RH side of the

control board box .

X Restore all press-fit connections in the correct

allocation (see above).

X Use a cable tie to fasten the cables running to

the LH and RH side of the cable duct to the

fixing pedestal (on control board box). Make

sure the cables and press-fit connections are

not subjected to strain.

X Place the cover back on the control board.

X Perform the appropriate “Final Steps”.

4.3.2.10 Exchanging the Solenoid Valve on Left or Right (and/or Cable)

X Turn the machine and then the flow of compressed air ON.

X Disconnect the movable changeover table from the machine and move it out of the machine.

X Switch off the supply of compressed air to the compressed air unit and actuate the needle valve on

the compressed air unit to bleed the compressed air lines.

X Turn the machine OFF and disconnect it from the mains supply.

WARNING:

There is a high risk of injury from the blades and the tape deflector.

Never reach into the cutter from below or into the empty-tape duct from above.

NOTE: The cutter remains installed in the machine.

If the cable of the solenoid valve is faulty:

X Carefully undo the relevant cable ties (left or right) on the outside of the control board box(10).

 -> Do not damage the cables in this process.

X Remove the cover from the control board (9).

X Unplug the press-fit connection for the "control board for tape cutter - valve" cable of the appropriate

solenoid valve at the control board.

X Unplug the press-fit connection for the "control board for tape cutter - valve" cable at the appropriate

solenoid valve.

X Remove the cover from the cable duct (5).

X Remove the cable and run the new "control board for tape cutter - valve" cable.

 Push the excess lengths of cable into the cable duct.

X Reconnect the press-fit connections at the correct points on the board and solenoid valve.

X Refit the cover on the control board (9).

X Install the cover on the cable duct (5).

X Use a cable tie to fasten the cables running to LH and/or RH side of the cable duct to the fixing

pedestal (on control board box).

 Make sure the cables/press-fit connections are not subject to strain (8).

X Perform the "Final Steps".

If the solenoid valve is faulty:

X Undo the 2 compressed air connections on the one-way restrictors at the faulty solenoid valve

(1, 2, 6).

X Unplug the press-fit connection for the "control board for tape cutter - valve" cable at the defective

solenoid valve (11).

X Undo the screws fastening the faulty solenoid valve (2 M3 screws (4)) and remove the solenoid

valve.

X Fit the new solenoid valve in the correct position, as shown in the diagram above. Make the plug-

and-socket connection at the solenoid valve:

 -> Tighten the screws to the correct torque.

 -> The strain on the cable must be relieved (8).

X Mount the short-stroke cylinder compressed air connections to the one-way restrictors on the

solenoid valve with the correct allocation (6,7,8).

X Perform the "Final Steps".
