4.5.8.1 New Valve Positioning Drives (From Version 03)
New Valve Positioning Drives (From Version 03)
New valve positioning drives are now available which guarantee a reliable assembly position even if the
placement head is incorrectly placed down on its back.
The valve positioning drive can ONLY be fitted when the placement head has been dismantled, as the
locking threaded pin (Allen key, M1, 4x4) is only accessible from the back of the head.

New valve positioning drive holder for star placement po
-
sition with position locking
The holder for the valve positioning drives of the place-
ment and reject positions has an additional threaded pin.
After the motor mount has been fastened, this threaded
pin is tightened until it just touches the centering pin. The
valve positioning drive is now fixed so that its position can
not change towards the front.
Additional improvements have also been made to individ-
ual parts of the valve positioning drive.
NOTICE!
This holder also fits the valve positioning drive on the
placement and reject position of the DLM1 placement
head. A second 1.4 mm thread (1) is provided on the op-
posite 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.

Setting the valve positioning drive for the placement position
NOTICE
Adjustment valve plunger
The DLM1 (placement position) and all valve positioning drives of the DLM2, DLM3 and DLM4
heads can be set with the adjustment valve plungers.
► Fit the dismantled placement head onto the head
mount and place both down on the front or place the
placement head down on a soft, ESD conductible
surface on its front.
► The lockscrew (1) and the fastening screw (2) of the
valve positioning drive need to be loosened or are
only screwed in slightly during assembly of the drive.
► Instead of using a valve plunger, the adjustment
plunger is now inserted for the placement position
(P), as can be seen in the diagram.
► Turn the adjustment valve plunger so that the tips of
the two centering pins are near to the cam disk be-
hind the ball bearing. Use a pointed object to careful-
ly turn the cam disk so that it is in the "starting
position" (ball bearing horizontally aligned next to the
drive shaft).
► Carefully turn the star to 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 swivels in the correct
position (centering pins parallel to cam disk).
► Press the valve positioning drive in the direction of
the placement star and fasten the drive holder with
the 2.5 mm Allen key.
