CAUTION O
The toothed belt must not be stretched or kinked. 14
➠ Install the new d.c. geared motor in the reverse order to that described in section 14.3.1.1.
The HQWLUHZLGWK of the toothed belt must engage at the top and bottom synchronizing disk.
➠ Fasten the d.c. geared motor with the four M3 hexagonal socket head cap screws (see -> 5).
➠ Put the cable shoes on the motor terminals (+/-) in the correct polarity (direction of rotation!).
➠ Use the two heat-shrinkable sleeve rings to hold the cable to the circumference of the d.c.
geared motor.
➠ Install the sonar proximity switch mount (incl. sensor head) back on the motor mount (see ->
20).
➠ Perform the )LQDOVWHSVLQFOXGLQJIXQFWLRQFKHFN (see section 14.4).
NOTE:
After the gear motor has been installed, you must make certain that the direction of rotation and
the conveyor speed are correct (motor voltage). Proceed as stipulated in "Setting Instructions for
HS-50". 14

The following instructions apply for all 5 conveyor areas of conveyors 1 and 2. 14
NOTE
For this work the sonar proximity switch mount incl. sensor on the input and intermediate conveyor
must be removed and subsequently re-installed. During this process, the connecting cables are
not to be kinked or bent sharply. Carefully set the mount incl. sonar proximity switch down on the
machine base. 14

➠ For the removal from PCB conveyor 1, when dual conveyor involved:
Move the conveyor 1 only so far apart that the exterior of the movable conveyor assembly is
still sufficiently accessible to loosen the screws fastening the end shield (see -> 5).
➠ )RUWKHUHPRYDOIURPWKHVLQJOHFRQYH\RU Move the conveyor to PD[LPXPwidth.
➠ Move the Y-gantries into the area outside the PCB conveyor.
➠ Turn off the machine at the main switch and disconnect the machine from the mains.
➠ Conscientiously secure the machine against being turned back on during the servicing.
