Mechanical Adjustment (From Version 03)

Setting the valve positioning drive for the reject position

NOTICE

The valve positioning drives of the DLM1 and DLM3 head reject position can be set with the

adjustment valve plungers.

CAUTION

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 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.

► 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.

► Use a pointed object to carefully turn the cam disk so

that it is in the "starting position" (ball bearing horizon-

tally aligned next to the drive shaft).

► 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).

NOTICE! As the cam disk of the reject valve po-

sitioning drive is behind the connection board, this setting

is slightly more complex than that for the placement cir-

cuit.

► Press the valve positioning drive in the direction of

the placement star and fasten the drive holder with a

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.

► Then replace the adjustment plunger with a plunger

and protection ring.
