C&P12 Placement Head 4.5.9 Replacing the Valve Positioning Drive for the Reject Circuit [00367768-xx]
162 Service Manual SIPLACE D4/D4i
► Use a pointed object to carefully turn the cam disk so
that it is in the "starting position" (ball bearing horizon-
tally aligned next to the drive shaft).
► Carefully turn the placement star in the direction of
the valve positioning drive so that the two centering
pins behind the ball bearing grasp the fixtures on the
cam disk. The adjustment valve plunger (1) swivels
into the correct position (centering pins parallel to
cam disk).
NOTICE! As the cam disk of the reject valve po-
sitioning drive is behind the connection board, this setting
is slightly more complex than that for the placement cir-
cuit.
► Press the valve positioning drive in the direction of
the placement star and fasten the drive holder with a
2.5 mm Allen key.
► Now tighten the locking threaded pin with an Allen
key of size 0.89 mm. Press the valve positioning drive
against it. Do not tighten excessively as this could
push the valve positioning drive "backwards".
► Remove the adjustment plunger by turning the place-
ment star back and then rotating the adjustment
plunger out of the valve housing.
► Then replace the adjustment plunger with a plunger
and protection ring.

socket-head screws (1) to fix the flat ribbon cables.
CAUTION! Check how the cables are run!
Make sure that the flat ribbon cable is not pinched in the
guide channel.Make sure that you push the folded part of
the flat ribbon cable for the "Z axis up" light barrier back
under the illumination board.
