Service Manual SIPLACE Placement Heads DLM3/DLM4 37

Installation

► Further installation is performed by following the above instructions in the reverse order.

1. Valve positioning drive for the placement circuit

[00368075-xx]

2. Valve positioning drive for the reject circuit

[00367768-xx]

► Loosen the fastening screw (4).

► Carefully remove the valve positioning drive (2).

► Insert the valve positioning drive. Make sure that it is

seated correctly on the parallel pins (5).

► Loosely screw in the hexagon socket-head screw (4).

► Use the cable clamps to fix the ribbon cable in posi

tion. Make sure that the ribbon cables are not

pinched.

CAUTION!

Check how the cables are run!

Check that the ribbon cables are laid correctly (1).

The flat ribbon cable for the two valve positioning units

must be run outside the holes (2). It will otherwise be

damaged when the head is fitted onto the head plate.

New valve positioning drive holder for the reject position

(DLM2/3) with position locking function

These valve positioning drives replace the previous ver

sions on the DLM2/3 head.

For precise alignment and adjustment of the drives, use

the new tool which replaces the distance gauge 0.2 mm

[00325445-xx].

NOTICE! This holder also fits the valve position

ing drive on the placement and reject position of the

DLM1 head. A second 1.4 mm thread (1) is provided on

the opposite side for this purpose.

Distance gauge

Instead of using the adjustment valve plungers, the DLM1 and DLM2 heads can also be set

with the distance gauge.

1. Stepping motor

2. Cam disk

3. Deep-groove ball bearings

4. Valve plunger

5. Valve casing

6. M3x10 hexagon socket-head screw

7. Valve positioning drive (flange)

► 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.

Valve plunger version 03

(C&P12: [00351498

03], C&P6: [00351500

03])

► 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.
