NOTE
The lifting table motors are prefitted with cable and connector (different article numbers, depend-
ing on placement area 1-4). 9
➠ Undo and remove the six M4 hexagonal socket head cap screws on the clamping flange . Re-
move the annular spring under the clamping flange.
➠ Label the allocation of the proximity switch for "lifting table up" and "lifting table down" .
➠ Remove the 2 proximity switches from the motor mount (two M3 hexagonal socket head cap
screws), , and take off the "reinforcement plate for proximity switch" in the process.
Set the proximity switch down on the mounting plate.
➠ Fold up the transmission lever on the motor mount.
➠ Undo and remove the 2 hexagonal socket head cap screws on the sprocket wheel .
Be careful with the washers underneath and remove the sprocket wheel incl. cam body.
➠ Lift off the cover of the pertinent cable duct which is parallel to the conveyor assembly.
➠ Carefully (!) remove the corresponding cable ties.
➠ In the cable duct, disconnect the plug-and-socket connection of the lifting table motor which is
to be removed (X70 / X71 / X72 / X73: see circuit diagram for "Power supply for lifting table
motors 1 - 4").
NOTE:
If you discovered a break in the lifting table cable during a continuity test, the cable to the power
supply unit must be run on a weaving course and disconnected at the corresponding connector
X5 / X 6 / X7 / X8 (see above-mentioned circuit diagram).
You may wish to contact Siemens SMD Service regarding this work. 9
➠ Undo and remove the screws fastening the motor to the motor mount (four M5 hexagonal
socket head cap screws) and pull the lifting table motor out.
9.5.3.2 Installing the Lifting Table Motor / Sprocket Wheel
➠ Install the new lifting table motor and the (new) sprocket weel in the reverse order to that de-
scribed for the removal.
The pin in the sprocket wheel secures the sprocket wheel in the correct position.
11) Screws fastening the "sprocket wheel with
lead tapes": 2 hexagonal socket head cap
screws M 3 x 30 with 2 adjusting shims
12) Motor moiunt: 4 hexagonal socket head
cap screws M5 x 12
13) Transmission lever 14) Motor for lifting table 1, 2, 3 or 4

CAUTION
When several lifting table motors are being removed/installed at the same time, check that the
plug-and-socket connections in the cable duct are allocated correctly (see the circuit diagram
:Power supply for lifting table motors 1 - 4"). The strain on the plug-and-socket connections must
be relieved after the cable ties are attached. 9
➠ Remove all tools, etc., form the working area of the machine.
➠ Fold the transmission lever on the lifting table motor down .
➠ Install the lifting table plate as described in .
➠ Carry out the pertinent "Final steps including the function check".
