Adjusting the "Z axis down" sensor
► Set the distance between the white sleeve ring and the light barrier to 0.95 -1.15 mm.
⇨ Use a test probe or drill (diameter 1.0 mm) for this.
⇨ Check the distance with a test probe or drill (diameter 1.2 mm). – This drill should not fit!

► Thread the sensor cable from the Z axis into the front
part of the C&P head.
► Fix the sensor (1) in position with the screw provided
(2) and initially screw loosely into the jaw of the Z ax-
is.
► Fix the cable into place with the cable clamps.
► Check how the cable is run inside the front part of the
C&P head:
⇨ If the Z axis has been pushed right out, the cable
should lie loosely around the housing for the star
drive shaft. The cable must NOT be pulled tight.
⇨ If the Z axis is pushed right in, the cable should run
freely inside the front part of the C&P head, with-
out touching the rotary encoder for the DP axis.
CAUTION!
Check how the cables are run!
If the radius of the curvature is too small, the Z axis could
jam or the light barrier cable could break.
► Once the cable is run in line with the required condi-
tions, fix it in place with the angled clips.
► Connect the cable plug to the slot on the intermediate
distributor.

the jaws and the side edges of the circular arc guide.
The gap may be between 0.02 and 0.03 mm.
Adjust the jaws if necessary.
Reassemble the placement head as follows.
