Mechanical Adjustment (All Versions)
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).

► 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.
► 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".
► Remove the adjustment plunger by turning the place
-
ment star back and then rotating the adjustment
plunger out of the valve housing.
