168 Service Manual SIPLACE D4/D4i
Installation
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!
► Fix the light barrier in place with the two screws provided.
► Fit and adjust the star.
► Fit the front part of the C&P head.

6.3.1 Calibrating the C&P Head and Cameras [ ➙ 206]
► 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.

Removal
► (1) Rotate the star into the position shown and then
remove the Z axis from its guidance by taking hold of
the mounting plate.
Clean the contact surface with SIPLACE cleansing
tips and ethanol.
► (2) Push the new Z axis guide into the groove provid-
ed.
Press the reference edge (inner side) of the Z axis
into the groove and fix the Z axis with the screws pro-
vided.
► (3) Use the feeler gauge to check the gap between
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.
NOTICE!
The board must be fitted centered to the jaws.
Make sure that the board does not rub against the frame
(check with gauge if necessary).
Complete the following step at every second service in-
terval for the head:
► (4) Use the mini oiler device to apply a small amount
of oil [00367071-xx] to the drilling provided.
Make sure that there is not too much oil coming out
of this hole.
NOTICE!
Where dirt is not excessive, the oil can be directly applied
to the rail.
Refit the front part of the C&P head. (See "4.5.2 Remov-
al/Installation of Head Front Part" [ ➙ 143].)
