➠ 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 engagedLQDOOsynchronizing disks over

➠ 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 EHOWJXLGHin the correct position (see section 14.3.2.2).
➠ If necessary, adjust the DOLJQPHQWRIWKHJXLGHUDLOV (see section 14.3.7).
➠ Carry out the )LQDOVWHSVLQFOXGLQJIXQFWLRQFKHFN (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 DOOthe 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 PRYDEOHside 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.

The new toothed belt must not be stretched or kinked. 14
➠ Place the new toothed belt of the conveyor in the guide channel of the fixed side of the con-
veyor.
➠ Carry out DOOsteps in the reverse order to those taken during removal (see section 14.3.2.2).
➠ Check: The toothed belt for the conveyor must be engaged in DOOsynchronizing disks RYHU

➠ Make certain that the polarity of the motor terminals (+/-) is correct (= correct direction of rota-
tion).
➠ Fasten the motor cable to the circumference of the geared motor with the heat-shrinkable
sleeve.
CAUTION O
The connecting cables for the sonar proximity switch must not be damaged or kinked. 14
➠ Where applicable, install the sonar proximity switch mount incl. sensing head.
➠ Fasten the EHOWJXLGHV(see -> 2) in the slots in the correct position (two M3 hex socket head
cap screws):
– The toothed belt must be in contact with the upper edge of the conveyor assembly
along its entire length and must not be under tension in the remaining area.
➠ Install the guide rails on the fixed side of the conveyor assembly.
➠ Adjust the DOLJQPHQWRIWKHJXLGHUDLOV(see section 14.3.7).
➠ Carry out the pertinent "Final steps including function check" (see section 14.4).
In the process, make certain the geared motor rotates in the correct direction.

➠ Lift the new conveyor belt in over the conveyor drive unit which has been removed.
➠ Place the new toothed belt in the guide channel of the movable conveyor side -> The con-

For the function check, transport a PCB from the input or preceding station to the output or fol-
lowing station.
