CAUTION! Check how the cables are run!
Check that the ribbon cables are laid correctly (1).
The flat ribbon cable for the two valve positioning units
must be run outside the holes (2). otherwise it will be
damaged when the C&P head is fitted onto the head
plate.

New valve positioning drive holder for the reject position
(DLM2/3) with position locking function
These valve positioning drives replace the previous ver-
sions on the DLM2/3 placement head.
For precise alignment and adjustment of the drives, use
the new tool which replaces the distance gauge 0.2 mm
[00325445-01].
NOTICE! This holder also fits the valve position-
ing drive on the placement and reject position of the
DLM1 placement head. A second 1.4 mm thread (1) is
provided on the opposite side for this purpose.
NOTICE
Instead of using the adjustment valve plungers, the DLM1 and DLM2 heads can also be set
with the distance gauge.

► Use the feeler gauge to set the distance between the
valve plunger and valve casing to 0.2 mm (A).
► Turn the cam disk (2) until the deep-groove ball bear-
ings (3) point towards the valve casing.
► Move the valve positioning drive (7) so that the deep-
groove ball bearings (3) come into contact with the
valve plunger (4) at position (B).
► Use the hexagon socket-head screw to fix the adjust-
ment unit in this position (6).
► Fit the C&P head.
► Use the SITEST program to test that the valve posi-
tioning drive is functioning correctly.
► Use the SITEST program to calibrate the C&P head.

► If the new valve plungers are used (s. diag. on left)
proceed as follows:
⇨ Take out one valve plunger and remove the sleeve
(2).
⇨ Insert the plunger without bushing and carry out
the following steps on this segment:
► Insert the distance gauge (0.2 mm) between valve
plunger and valve casing.
► Rotate the valve positioning drive 90 degrees from its
initial position. The eccentric of the valve adjustment
drive will just touch the inner side (1) of the valve
plunger.
► Fix the motor of the valve drive in this position.
► Remember to replace the tube on the valve plunger.
