7.9.4 Fitting the valve positioning drive
Æ Insert the valve positioning drive, making sure that it is seated correctly on the parallel pins.
Æ Loosely tighten the hexagon socket-head screw.
Æ Use the cable clamp assemblies (items 2, 3, and 4 in Fig. 7.9 - 2) to fix the ribbon cables in
position, ensuring that the ribbon cables are not squashed.
CAUTION 7
Check that the ribbon cables (item 1 and 2 in Fig. 7.9 - 2
) are laid correctly. The ribbon cable
(item 2 in Fig. 7.9 - 2
) from the valve adjustment unit to the reject station (item 6 in Fig. 7.9 -
2) must run outside the hole (item 5 in Fig. 7.9 - 2), otherwise it will be damaged when the
collect&place head is fitted on the head mount. 7

(item A in Fig. 7.9 - 3
).
Æ Turn the adjusting disk (see item 2 in Fig. 7.9 - 3) until the deep-groove ball bearings (item 3
in Fig. 7.9 - 3
) point towards the valve casing.
Æ Move the valve positioning drive (item 7 in Fig. 7.9 - 3) so that the deep-groove ball bearings
(item 3 in Fig. 7.9 - 3
) come into contact with the valve plunger (item 4 in Fig. 7.9 - 3) at
position B.
Æ Use the hexagon socket-head screw (item 6) to fix valve adjustment unit in this position.
