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 compessed 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).
à Remove the cover from the control board (see Fig. 11.6.5 -> 14).
à Carefully undo the cable ties (left and right) on the outside of the control board box (see
Fig. 11.6.6 -> 10).
-> Do not damage the cables in this process.
à Mark the allocation of all plug-and-socket connectors and disconnect all plug-and-socket con-
nections on the control board (se Fig. 11.6.5).
à Disconnect the control unit (box) from the support bar by pushing both of the spring-mounted
elements away from the bar (see Fig. 11.6.5 -> 12, 13).
à Install the new control unit (Item no.: see Section 11.2), correctly rotated and positioned, on the
bar and engage the unit.
à Mount an adhesive fixing pedestal for cable ties (see Section 11.2 for Item no.) on the outside
LH and RH side of the control board box (see Fig. 11.6.6 -> 10 for location).
à Restore all plug-and-socket connections in the correct allocation (see Fig. 11.6.5).
à Use a cable tie to fasten the cables running to the LH and RH side of the cable pit to the fixing
pedestal (on control board box). The strain on the cables/plug-and-socket connections must
be relieved (see Fig. 11.6.6 -> 8).
à Place the cover back on the control board.
à Perform the appropriate “Final Steps” (see Section 11.6.11).
