► Turn the machine and then the flow of compressed air ON.
► Disconnect the movable changeover table from the machine and move it out of the machine.
► Turn the machine OFF,
► Remove the cover from the control board.
► 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.
► Mark the allocation of all press-fit connections and disconnect all press-fit connections from the con-
trol board.
► Disconnect the control unit (box) from the support bar by pushing both of the spring-mounted ele-
ments away from the ba.
► Carefully insert the new control unit onto the rail, in the correct rotary position and location, until it
locks into place.

Exchanging the Solenoid Valve on Left or Right (and/or Cable)
► Turn the machine and then the flow of compressed air ON.
► Disconnect the movable changeover table from the machine and move it out of the machine.
► 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.
► Turn the machine OFF and disconnect it from the mains supply.
Control Unit
► Mount an adhesive fixing pedestal for cable ties on
the outside LH and RH side of the control board box .
► Restore all press-fit connections in the correct alloca-
tion (see above).
► 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.
► Place the cover back on the control board.
► Perform the appropriate “Final Steps”.
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.
NOTICE
The cutter remains installed in the machine.

4.3.2 Cutter Component Handling
Service Manual SIPLACE D4/D4i 103
If the cable of the solenoid valve is faulty:
► 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.
► Remove the cover from the control board (9).
► Unplug the press-fit connection for the "control board for tape cutter - valve" cable of the appropriate
solenoid valve at the control board.
► Unplug the press-fit connection for the "control board for tape cutter - valve" cable at the appropriate
solenoid valve.
► Remove the cover from the cable duct (5).
► Remove the cable and run the new "control board for tape cutter - valve" cable.
⇨ Push the excess lengths of cable into the cable duct.
► Reconnect the press-fit connections at the correct points on the board and solenoid valve.
► Refit the cover on the control board (9).
► Install the cover on the cable duct (5).
► Use a cable tie to fasten the cables running to LH and/or RH side of the cable duct to the fixing ped-
estal (on control board box).
⇨ Make sure the cables/press-fit connections are not subject to strain (8).
► Perform the "Final Steps".
If the solenoid valve is faulty:
► Undo the 2 compressed air connections on the one-way restrictors at the faulty solenoid valve
(1,2,6).
► Unplug the press-fit connection for the "control board for tape cutter - valve" cable at the defective
solenoid valve (11).

► Undo the screws fastening the faulty solenoid valve (2 M3 screws (4)) and remove the solenoid
valve.
► 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).
► Mount the short-stroke cylinder compressed air connections to the one-way restrictors on the sole-
noid valve with the correct allocation (6,7,8).
► Perform the "Final Steps".

Exchanging the Inductive Proximity Switch
Removing the Proximity Switch
► The cutter remains installed in the machine.
► Turn the machine and then the flow of compressed
air ON.
► Disconnect the movable changeover table from the
machine and move it out of the machine.
► Turn the machine OFF,
► Remove the cover from the control board (14).
► 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.
► Using a fine-tip permanent marker, precisely mark on
the short-stroke cylinder the specified position of the
proximity switch that is to be exchanged.
► Unplug the press-fit connection for the defective prox-
imity switch from the control board (for allocation see
diagram). If you loosen more than one of the press-fit
connections simultaneously, mark the allocation.
► Remove the cover from the cable duct.
► Undo the screw fastening the proximity switch to the
short-stroke cylinder (1 screw: see picture) and re-
move the proximity switch including the cable.
