Fig. 14.3.8 Removing the Motor of the Width Adjustment System or the Drive of the Width Adjust. System (Complete)
Key to Fig. 14.3.8
➠ In the cable duct, disconnect the plug-and-socket connection for this motor of the width adjust-
ment system (;RU;: see circuit diagram for "6/,2PRGXOHRQ3&%FRQYH\RU
or RQ3&%FRQYH\RU.
NOTE:
If you have discovered a break in the motor cable during a continuity check and this break is up-
stream of the plug-and-socket connection, the motor cable must be run on a weaving course as
far as the "conveyor control PCB 1" / "... PCB 2" (see ) and unplugged at the connector X3 of
the corresponding "conveyor control" (see above-mentioned circuit diagram). This may be some-
what complicated due to the routing of the cable inside the machine base.
You may wish to contact Siemens SMD Service regarding this work. 14

CAUTION O
The new toothed belt is not to be stretched or kinked. 14
➠ Install the new stepping motor in the reverse order to that described above for the removal. Bolt
the motor to the drive housing.
➠ Check: The HQWLUHZLGWKof the toothed belt must be engaged on the synchronizing disk
➠ Remove all tools, etc., from the working area of the machine.
➠ Make certain that the transmission lever on the lifting table motor mount is folded onto the lift-
ing curve (see Fig. 14.3.5, illustration bottom left).
➠ Re-install the lifting table as described in section 14.3.8.2.
➠ Carry out the appropriate )LQDOVWHSVLQFOXGLQJWKHIXQFWLRQFKHFN(see section 14.4).
During the function check, move the conveyor to its maximum and minimum width.

NOTE:
Exchange the entire unit "Drive for width adjustment system", e.g., in case of a fault in the ball
bearing/syconronizing disks and motor. 14

➠ Remove the lifting table as described in section 14.3.8.1.
➠ Relieve the stress on the large toothed belt for the width adjustment system as described
above in section 14.3.12.1 .
Take the large toothed belt off the sprocket wheels of the drive unit.
➠ Detach the plug-and-socket connection of the motor of the width adjustment system LQWKHFD
EOHGXFWas described above in section 14.3.13.1.
➠ Undo and remove the screws fastening the drive housing to the assembly base plate (2 hex-
agonal socket head cap screws M6: see Fig. 14.3.8 -> 8). Lift the "Drive for the width adjust-
ment system" out.

➠ Install the new "Drive for the width adjustment system" in the reverse order to that following
during removal.
➠ Place the large toothed belt for the width adjustment system on the deflection pulleys.
➠ Check: The HQWLUHZLGWKof the toothed belt must be engaged on the two outside synchronizing
disks (on the pedestal) and must be in contact with the circumference of the deflection pulleys.

➠ 3ODFHWKHODUJHWRRWKHGEHOWXQGHUWHQVLRQ as described in section 14.3.12.2 for the instal-
lation of the "Toothed belt for the width adjustment system".
➠ Remove all tools, etc., from the working area of the machine.
➠ Make certain that the transmission lever on the lifting table motor mount is folded onto the lifting
curve (see Fig. 14.3.5, illustration bottom left).
➠ Where applicable, re-install the lifting table as described in section 14.3.8.2.
➠ Carry out the pertinent )LQDOVWHSVLQFOXGLQJIXQFWLRQFKHFN(see section 14.4). During the

NOTE:
The limit switches are preassembled including the cables. Nevertheless, the wiring can also be
unsoldered/soldered right at the switch in question if you discover that the limit switch itself is
faulty. 14
➠ Remove the lifting table as described in section 14.3.8.1.
➠ Mark the position of the limit switch on the rail with a fine permanent marker.
➠ Unsolder the connection wires on the faulty limit switch (allocation: see circuit diagram &RQ
YH\RUFRQWURO3&% or 3&%. Comply with the NOTE below.
➠ Remove the faulty limit switch (two M2 slotted screws: see Fig. 14.3.9 -> 7 -10).
NOTE:
If you have discovered a break in the limit switch cable during a continuity check, the cable must
be run on a weaving course as far as the corresponding "Conveyor Control PCB 1" / "... 2" (al-
location: see ) and must be unplugged there at connector X12 / X13 (see above-mentioned circuit
diagram).
This may be somewhat complicated depending on the cable routing inside the machine base.
