➠ 5HOLHYHWKHWHQVLRQon the relevant pair of toothed belts by loosening the fasteners of the al-
located EHOWJXLGH on the fixed DQGmovable side of the conveyor (two M3 hexagonal socket
head cap screws each: see!).
➠ When exchanging at the LQWHUPHGLDWHRULQSXWFRQYH\RU
Where applicable, disassemble the sonar proximity switch mount incl. the sensing head ->
Keep the above NOTE in mind.
➠ Mark the polarity of the motor terminals (+/-) -> Important for restoring the direction of rotation.
➠ Pull the cable shoes off the motor terminals.
➠ Pull the heat-shrinkable sleeves (which hold the cable in place) off the motor.
➠ For the exchange at conveyor 1 or 2:
➠ On the movable side of conveyor 1 or 2 undo the screws fastening the end shield ((3 slotted
M2 screws: see -> 5).
➠ If a dual conveyor is present (and the toothed belt on conveyor 1 is exchanged) also
loosen the screws fastening the end shield at conveyor 2.
➠ $WWKHIL[HGVLGHRIWKHFRQYH\RU
➠ Undo and remove the screws fastening the pertinent motor mound (two M 4 hexagonal
socket head cap screws: see ).
➠ In case involving both a dual converter and exchanging the toothed belt at conveyor 1, the
screws fastening the motor mount must be undone (see -> 4). This creates space to re-
move the end shield, moving in the direction of conveyor 2.
➠ On the drive unit, remove the pressure disk, the annular spring (tensioning element) and
the synchronizing disk from the hexagonal drive shaft.
➠ Push the drive unit toward the movable side of the conveyor until the synchronizing disk of
the drive no longer engages in the toothed belt of the conveyor.
Where a dual conveyor is present (and the toothed belt on conveyor 1 exchanged), first
push the drive shaft of conveyor 2 away from conveyor 1 to make room for the drive shaft
of conveyor 1. Then push the drive shaft of conveyor 1 away too.
➠ Remove the damaged toothed belt for the drive from the motor mount.

CAUTION O
The new toothed belt is not to be stretched or kinked during the following procedure. 14
➠ Insert the new toothed belt into the relief cut in the motor casing (see ).
➠ Place the toothed belt around the synchronizing disk of the geared motor.
➠ In the opening of the motor mount, pull the toothed belt up slightly but do not stretch it.
➠ Guide the hexagonal drive shaft with synchronizing disk (see ) into the motor mount.

➠ Place the external synchronizing disk, the annular spring and the plain washer onto the end of
the hexagonal drive shaft and bolt the drive shaft to the motor mount (one M3 hexagonal socket
head cap screw).
➠ Check: The toothed belt must be engaged in the top and bottom synchronizing disk over its
entire width (see ).
➠ Carry out the remaining assembly procedures in the order reverse to that described for the dis-
assembly in section 14.3.2.1, above.
➠ Restore the correct polarity of the motor terminals (+/-) -> direction of rotation!direction of ro-
tation
➠ Fasten the motor cable to the circumference of the motor with the heat-shrinkable sleeve.
➠ If applicable, mount the sonar proximity switch mount incl. the sensing head.
– The connecting cables of the sonar proximity switch are not to be damaged or kinked.
➠ Fasten the EHOWJXLGHV(see ) in the FRUUHFWSRVLWLRQin the slots (two MS hexagonal socket
head cap screws) and note:
– The toothed belt is not to be under tension.
➠ Carry out the pertinent "final steps incl. function check" (see section 14.4). During the process,
make certain that the geared motor will turn in the correct direction.

CAUTION O
The toothed belt is not to be stretched or kinked. 14
NOTE:
If the ball bearing in teh motor mount is faulty, exchange the motor mount assembly for PCB con-
veyor". If the geared motor ist faulty as well, exchange the "PCB conveyor drive" (= entire unit in-
cluding geard motor). 14

➠ Carry out DOOsteps as described in section 14.3.2.1 for the removal of the "toothed belt for PCB
conveyor drive. The toothed belt in the motor mount is removed, however, because the above-
mentioned assemblies LQFOXGHLW(see NOTE).
➠ Pull the motor mount with geared motor off the drive shaft.
➠ If you wish to exchange the "motor mount assembly", remove the geared motor for re-use with
the motor mount (four M3 hexagonal socket head cap screws: see ).

➠ Install the new "motor mount assembly for PCB conveyor" or the new unit "PCB conveyor
drive" in the reverse order (see VHFWLRQ and ).
➠ Check: The toothed belt for the conveyor must be engagedLQDOOsynchronizing disks over
its HQWLUHZLGWK
➠ If guide rails have been loosened or removed, install the guide rails on the conveyor assembly.
Do not tighten them completely yet because they will have to be adjusted.
➠ Re-fasten the EHOWJXLGHin the correct position (see section 14.3.2.2).
➠ If necessary, adjust the DOLJQPHQWRIWKHJXLGHUDLOV (see section 14.3.7).
➠ Carry out the )LQDOVWHSVLQFOXGLQJIXQFWLRQFKHFN (see section 14.4).
Keep the following NOTE in mind.
NOTE:
After the new unit "PCB conveyor drive" is installed, you have to make certain that the direction of
rotation and the conveyor speed are correct (motor voltage).
After the geared motor has been re-connected, you only have to check the direction of rotation.14

NOTE
The relevant components of the fixed conveyor side are arranged in a like manner to those of
the movable side (see ).
All conveyor toothed belts other than those for the intermediate conveyors, have the same Item
No. 14
The following instructions apply to all 5 PCB conveyor areas of conveyors 1 and 2. 14

➠ Carry out DOOthe steps described for toothed belt of the PCB conveyor drive in section 14.3.2.1.
The short toothed belt in the motor mount is not removed however.
➠ Push the drive unit toward the PRYDEOHside of the conveyor until the synchronizing disk of the
drive no longer engages in the toothed belt for the conveyor.
➠ Support the drive unit in such that the hexagonal drive shaft is not bent.
➠ Remove the guide rails on the fixed side of the conveyor (M3 hexagonal socket head cap
screws: see ).
➠ Remove the faulty toothed belt for the conveyor from the guide channel of the fixed side of the
conveyor.
