DANGER
Please observe the safety instructions in Chapter 2.
CAUTION
The toothed belts must not be stretched or kinked!
6.8.1 Removal
The DC geared motors, including the motor mounts of all 5 conveyor areas, are of like construc-
tion. Please bear in mind the following differences during assembly and disassembly.
– The motor mount in installed at an angle (tilted), according to the requirements of the installa-
tion site.
– Depending upon the installation position, the motor mount will either be fixed with a clamping
ring or a circlip.
Conduct the procedures for replacement of all DC geared motors as described below:
Æ Remove the complete drive unit, as described in Section 6.7.
Æ Working from the fixed exterior side of the conveyor, undo the screws fastening the DC geared
motor (4 hexagonal socket-head screws, see Fig. 6.8.4
).
Æ Tilt the DC geared motor with its synchronized disk a little, so that the small toothed belt of the
drive comes free of the synchronizing disk and then pull the motor out.
Please note:
– The toothed belt on the motor pinion must not be stretched or kinked during this pro-
cess.
– The synchronizing disk on the motor shaft must be moved out in such a manner that is does
not get caught in the toothed belt.
NOTE:
If you have discovered a break in the motor cable during to a continuity check, the motor cable
must be woven out as far as the conversion board of the conveyor side (see circuit diagrams
of the same name) and unplugged at the corresponding point. This may be somewhat compli-
cated depending on the routing of cables inside the machine base.You may wish to contact Sie-
mens Dematic AG SMD Service regarding this work.

6.8.2 Installation
CAUTION
The toothed belt must not be stretched or kinked!
Æ Install the new DC geared motor in the reverse order
The entire width of the toothed belt must engage at the top and bottom synchronizing disk.
Æ Fix the DC geared motor with the 4 M3 hexagonal socket-head screws (see Fig. 6.8.4).
Æ Install the complete motor unit as described in Section 6.7.3.
Æ Perform the „Final steps including function check“ (see Section 6.18).
NOTE:
After the new drive unit has been installed, you must make certain that the direction of rotation
and the conveyor speed (motor voltage) are correct.
After reconnecting the geared motor, you will only need to check the direction of rotation.
