4.5.9.1 New Valve Positioning Drives (From Version 03)
4.5.9.2 Mechanical Adjustment (Up To Version 02)
4-47: New valve positioning drive holder for the reject position (DLM2/3) with
position locking function
These valve positioning drives replace the
previous versions 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].
NOTE:
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 opposite side for this
purpose.
NOTE:
Instead of using the adjustment valve plungers, the DLM1 and DLM2 heads can also be set with
the distance gauge.

X Use the feeler gauge to set the distance
between the valve plunger and valve casing to
0.2 mm (A).
X Turn the cam disk (2) until the deep-groove
ball bearings (3) point towards the valve
casing.
X 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).
X Use the hexagon socket-head screw to fix the
adjustment unit in this position (6).
X Fit the C&P head.
X Use the SITEST program to test that the valve
positioning drive is functioning correctly.
X Use the SITEST program to calibrate the C&P
head.
4-48: Valve plunger version 03 (C&P12: [00351498-03], C&P6: [00351500-
03])
X 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:
X Insert the distance gauge (0.2 mm) between
valve plunger and valve casing.
X 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.
X Fix the motor of the valve drive in this position.
X Remember to replace the tube on the valve
plunger.

4.5.9.3 Mechanical Adjustment (From Version 03)
Setting the valve positioning drive for the reject position
NOTE:
The valve positioning drives of the DLM1 and DLM3 head reject position can be set with the
adjustment valve plungers.
ATTENTION:
Even if your placement machine does not use the valve positioning drive for rejecting
components (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.
X Fit the dismantled placement head onto the
head mount and place this down on the front
or place the placement head down on a soft,
ESD conductible surface on its front.
X The lockscrew (at the bottom side of the
placement head) and the fastening screw of
the valve positioning drive need to be
loosened or are only screwed in slightly during
assembly of the drive.
X Fit the adjustment valve plunger (1) in place of
the valve plunger, for the reject position (R) -
as shown in the diagram.
X Turn the adjustment valve plunger so that the
tips of the two centering pins are near to the
cam disk behind the ball bearing.
