Distance gauge
Instead of using the adjustment valve plungers, the DLM1 and DLM2 heads can also be set
with the distance gauge.

2. Cam disk
3. Deep-groove ball bearings
4. Valve plunger
5. Valve casing

► 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 "reject position"
NOTICE
Adjustment valve plunger
The valve positioning drives of the DLM2 and DLM3 head reject position can be set with the
adjustment valve plungers.
CAUTION
Position must be correct
Even if your placement machine does not use the valve positioning drive for rejecting compo
-
nents (rejection vertically down), the position of this drive must still be correct. If this is not the
case, an incorrectly set valve positioning drive could have a negative influence on the plunger
positions during the reference run and during star rotation.
► 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 (at the bottom side of the placement
head) and the fastening screw of the valve position
-
ing drive need to be loosened or are only screwed in
slightly during assembly of the drive.
► Fit the adjustment valve plunger (1) in place of the
valve plunger, for the reject position (R) - as shown 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.
