X Thread the sensor cable from the Z axis into
the front part of the C&P head.
X Fix the sensor (1) in position with the screw
provided (2) and initially screw loosely into the
jaw of the Z axis.
X Fix the cable into place with the cable clamps.
X 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,
without touching the rotary encoder of the DP
axis.
ATTENTION: 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.
X Once the cable is run in line with the required
conditions, fix it in place with the cable clamps.
X Connect the cable plug to the slot on the
intermediate distributor.

The permissible gap is between 0.02 and 0.03
mm.
Readjust the jaw if necessary.
Reassemble the placement head as follows.
