Initial Operation

VTK-TR-BA-072e-1 - User Manual MDS 358X Series

Screw the Tappet Centering Screw BY completely into

the fluid box (torque 100 – 140 cN.m) with MDT 303 -

Nozzle Insert Changing Tool.

Make sure the three pins of the MDT 303 fit exactly

into the three holes of the Tappet Centering Screw

BY. Turn the MDT 303 clockwise while pressing it

down slightly to the fluid box.

Combine the MDT 303 with MDT 327 for a better

leverage.

Step 6 (nozzle insert)

Clip the nozzle insert into the fluid box. Use the small

hole of MDT 327 - Multi-Function Tool to pick up the

nozzle insert and to place it. Make sure the nozzle

insert sits flat.

Step 7 (nozzle fixation nut)

Screw the nozzle fixation nut clockwise onto the fluid

box. Use MDT 327 Multi-Function Tool.

Step 8 (cartridge base)

Place the cartridge base onto the fluid box and fix it

with the tightening screw. Screw the tightening screw

clockwise with MDT 327 Multi-Function Tool (torque

120 – 140 cN.m).

Important note!

In case you use a Cartridge Base without integrated

luer lock, you need to screw the Fluid Box Connector

Luer Lock into the top bore of the cartridge base CH.

Use the open-ended wrench of the MDT 327

(hexagon screw size M8, torque stainless steel 100 –

120 cN.m, PEEK 40 – 60 cN.m).

Optional (isolation body)

For thermally sensitive applications, you might use an

isolation body. Pull it onto the fluid box, until it clips

in. Screw it tight with the two screws for the isolation

body (torque 40 – 50 cN.m). Use the MDT 329 - L-

Shape hexagon Key 2 mm.

Step 9 (adjust screw)

Open the adjust screw completely. Screw counter-

clockwise. Use MDT 327 Multi-Function Tool.

Step 10 (fluid box)

Turn the locking lever by 180° from “Close” to “Open”

position.

Push the fluid box carefully in a 45° angle onto the

valve.

Straighten the fluid box and close the locking lever.

Optional positions

The bayonet fluid box has three different locking

positions (1: 90°, 2: 0°, 3: +90°) in which the valve can

be operated. To fix in locking position 1, mount the

fluid box at position a. To fix in locking position 2 or 3,

mount the fluid box at position b.

Step 11 (cartridge holder)

Screw the cartridge holder on top of the valve body

(torque between 40 – 50 cN.m). Use the MDT 329 or a

hexagon socket key size 2. Depending on the size of

the cartridge, you have to select the correct cartridge

holder. Hook the heater connection of the fluid box

into the cartridge holder (see blue arrow).

Step 12 (cartridge)

Push the cartridge through the cartridge holder and

screw it clockwise into the thread of the cartridge

base.

6.3 Installation of the Microdispensing System

Prior to installation, verify the conditions in the intended location, with respect to the

specification of the system and information detailed in this chapter.

The control unit and the valve have to be installed strictly in conformity with the procedures

described below. The system requires:

• Power supply

• Pneumatic supply

INFORMATION

Read chapter “Safety Notes” first

The entire procedure of installation is reserved to persons reliably informed about the safety

considerations (see chapter 2, page 8).

6.3.1 Installation of the Control Unit

The control unit is designed as a 19” plug-in module, which has to be fixed in the corresponding

rack by means of four pan-head screws at the front side. Leave sufficient space around the unit to

simplify service. Ventilation should be available. Recommended are cases complying with

enclosures according to EN 61010-1 with regard to fire protection.

IMPORTANT NOTE

Potential damage to the control unit

Do not close the four pan-head screws too tight; otherwise the front panel can be damaged (see

torque table Page 19).

To avoid overheating and ensure the required ventilation, a minimum distance between the

control unit and any other object should be maintained (at least 1.5 cm). Heat should neither be

accumulated nor externally be introduced. Do not obstruct natural convection. Ventilation from

the bottom side and air exhaust above is important. Minimum width of ventilation openings is

8 cm x 8 cm.

For high-duty applications (from ca. 300 Hz) or in the case of an air cooled model (AC variants), a

rack with separate ventilation is advisable, since in these situations an airflow of 30 m

/h for each

control unit is compulsory.

6.3.2 Installation of the Valve as Part of a Machine

Preferably, mount the valve on an automatic XYZ table or in a similar device (XYZ positioning

system). Stable seat at the fixture of Z-axis is imperative, as the valve should not become loose

during the dispensing process. For this purpose, insert two M4 hex screws to a depth of 4 mm,

through the bores located at the narrow side of the valve. Their distance center to center

amounts to 45 mm. To improve accuracy when positioning the valve on a receptacle,

additionally use the alignment bore and the long hole, located on the narrow side of the valve as

well.
