9.7.3 Sequence of Movements of the H and Z Jaws Levers
Please refer to the following diagram as you read the description of the sequence of movements in the
centering procedure.
Fig. 9.7.6 Sequence of movements of the h and z jaws levers
9.7.3.1 Sequence of Movements
1. The direct current servo motor moves the toothed rack and the toothed strip support towards the segment.
Here the h and z claws slide on the guide shaft towards the segment.
2. The deep-grooved ball bearings of the z jaws lever slide along the 45° incline of the z claw. The z jaws
close. At the same time the h jaws carry out a longitudinal movement until they are at the same height as
the z jaws.
3. The h and z claws move further on towards the segment. As soon as the z claw reaches the stop - that is,
the z jaws have closed to the defined separation - the closing movement of the h jaws lever begins.

4. The h claw slides further along the guide shaft as far as the stop on the housing. The h jaws are now fully
closed.
NOTE
The stop for the z claw and the guide for the h jaws lever are set in the factory and must on no account be
changed.
The guide is used for setting the longitudinal movement of the h jaws lever, while the stop determines the
minimum separation of the z jaws when closed.
9.7.4 Functional Sequence of the Centering Function with and without
CRDL Testing
When the CRDL option is installed, the centering station centers the components and checks their electrical
properties. Two procedures are available.
–
Centering with measurement and
–
Centering without measuring
With centering without measuring, the ceramic jaws close with reduced force so as not to damage fragile com-
ponents. The direct current servo motor for moving the toothed rack is controlled by the motor controller board
Y0009.
The logical bero signals
B1 ceramic jaws bero
B2 end position bero
