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.

X 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).

X Carefully turn the placement star in the

direction of 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 (1) swivels into the

correct position (centering pins parallel to cam

disk).

NOTE:

As the cam disk of the reject valve

positioning drive is behind the

connection board, this setting is slightly

more complex than that for the

placement circuit.

X Press the valve positioning drive in the

direction of the placement star and fasten the

drive holder with a 2.5 mm Allen key.

X 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".

X Remove the adjustment plunger by turning the

placement star back and then rotating the

adjustment plunger out of the valve housing.

X Then replace the adjustment plunger with a

plunger and protection ring.
