C&P12 Placement Head Replacing the Valve Positioning Drive for the Reject Circuit [00367768]

170 Service Manual SIPLACE D4

X Use a pointed object to carefully turn the cam

disk so that it is in the "starting position" (ball

bearing horizontally aligned next to the drive

shaft).

X 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).

NOTE:

As the cam disk of the reject valve

positioning drive is behind the

connection board, this setting is slightly

more complex than that for the

placement circuit.

X Press the valve positioning drive in the

direction of the placement star and fasten the

drive holder with a 2.5 mm Allen key.

X 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".

X Remove the adjustment plunger by turning the

placement star back and then rotating the

adjustment plunger out of the valve housing.

X Then replace the adjustment plunger with a

plunger and protection ring.
