3.8.1 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
head is incorrectly placed down on its back.
The valve positioning drive can ONLY be fitted when the 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 head. A sec

► 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 head.
► Check that the valve positioning drive is functioning
correctly.
► Calibrate the head.

► If new valve plungers (see diagram on left) are used,
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 positioning drive in this po

sition.
► 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 head onto the head mount and
place both down on the front or place the 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 carefully
turn the cam disk so that it is in the "starting position"
(ball bearing horizontally aligned next to the drive
shaft).
