4.3.1 Replacing the Complete Drive Unit [00359284] PCB conveyor system
Service Manual SIPLACE D1/D1i/D2/D2i 89
Installation
► Push the hexagonal shaft back and carefully remove
the motor mount (5). At the same time, carefully un-
thread the conveyor toothed belt.
CAUTION!
Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
NOTICE!
The way in which the conveyor toothed belt is run around
the belt guide depends upon the transport area con-
cerned. Please observe this belt guidance during as-
sembly.
► Fit the new drive unit in the reverse order.
► Please check:
The entire width of the conveyor toothed belt (4) must
engage at all toothed disks (7) and be run around the
belt guide (8).
► Perform the final steps including function test.
NOTICE!
After the new drive has been installed, check the direction
of rotation (polarity) and the conveyor speed with SIT-
EST.
After reconnecting the geared motor, you only need to
check the direction of rotation.
For the correct belt tension adjustment values, refer to
"6.7.1 Setting the Tension of the Conveyor Toothed Belt
and the Width Adjustment Unit" [ ➙ 261].

2. Fastening screws
3. Toothed disk (conveyor toothed belt)
4. Toothed disk (toothed belt for PCB conveyor drive)
The DC geared motors, including the motor mounts of all
3 conveyor areas, are of like construction. Please bear in
mind the following differences during assembly and dis-
assembly:
▪ The motor mount is installed either horizontally or
vertically, according to the requirements of the instal-
lation site.
► Move the flexible side of the PCB conveyor to a posi-
tion in which the drive unit is accessible.
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Mark the polarity (brown/white) of the cable connec-
tions (1) - important for the direction of rotation!
► Disconnect the cable shoes from the motor terminals
(1).
► The heat-shrinkable sleeves (4), which hold the con-
necting cable in place, must be stripped off the cir-
cumference of the DC geared motor.
► From the outer side of the conveyor, undo the fixtures
holding (2) the DC geared motor (5).
► You may need to disconnect the entire conveyor unit.
► Tilt the DC geared motor (5) a little, so that the small
toothed belt (3) comes free of the toothed disk.
CAUTION!
Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Pull the DC geared motor out.
► Please observe:
the toothed disk on the motor shaft must be moved
out in such a manner that it does not get caught in the
toothed belt.

Overview
CAUTION!
Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Insert the new DC geared motor (5) by following the
instructions in reverse order.
The entire width of the toothed belt (3) must engage
at the top and bottom toothed disks.
► Fix the DC geared motor (5) with the 4 M3 hexagonal
socket-head screws (2).
► Tension the toothed belt (3) by moving the DC geared
motor in the fastening holes. (See "6.7.1 Setting the
Tension of the Conveyor Toothed Belt and the Width
Adjustment Unit" [ ➙ 261].)
► Reconnect to the electrical system (1) and secure the
connection cable with a heat-shrinkable hose (4).
NOTICE
► After the new drive has been installed, check the direction of rotation (polarity) and the con-
veyor speed with SITEST.
