Initial Operation

VTK-TR-BA-171e-1 - User Manual MDS 3080-V

Step 3 (cartridge base)

Mount the cartridge base onto the fluid box. Use

MDT 327 or the MDT 306 - Torque Wrench Tool

VM with BitVM-A to fix the cartridge base with the

tightening screw by screwing clockwise (torque

110 – 120 cN.m).

Important Note!

There are two types of cartridge base: Cartridge

Base CH (without integrated luer lock) and

Cartridge Base CHI (with integrated luer lock). If

you use a Cartridge Base CH, 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).

Step 4 (tappet sealing)

Push the tappet sealing with the wider side down

onto the pin of an MDT 328. Push the MDT 328

with the tappet sealing straight into the fluid box.

When the tappet sealing sits tight, you will hear a

light noise.

Step 5 (tappet centering piece)

Press the tappet centering piece into the fluid box

body. Use the MDT 328 to make sure the tappet

centering piece is lying straight on the tappet

sealing.

Important Note!

When using a 2G tappet rod, you do not need a

tappet centering piece.

Step 6 (tappet and tappet centering screw)

Screw the Tappet Centering Screw BY into the

fluid box. Do not screw it tight yet. Screw it only

for two rotations.

Push the tappet rod with the tappet spring

slightly into the tappet centering screw. Place a

small droplet of Tappet Grease TF (Order no.

1014637; droplet size ca. 2 mm) on the tappet and

another on the tappet centering screw (for

placing see blue arrows in the picture). Make sure

that the tappet tip is free of grease. Rotate the

tappet and pull it in and out for three times to

spread the grease.

Push the tappet spring onto the Tappet Centering

Screw BY.

Push the tappet rod through the tappet spring

into the fluid box. Make sure the tappet goes

through the tappet sealing.

Screw the Tappet Centering Screw BY completely

into the fluid box (torque 100 – 140 cN.m). Use

MDT 303 - Nozzle Insert Changing Tool.

The three small pins of MDT 303 have to 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.

Alternatively, you can use the MDT 306 with

BitVM-B.

Step 7 (nozzle insert)

Use tweezers to pick up the nozzle insert and to

place it onto the fluid box body. Use the small

hole of MDT 327 to press the nozzle insert to

make sure the insert sits flat.

Step 8 (nozzle fixation nut)

Screw the nozzle fixation nut clockwise onto the

fluid box using the MDT 327. Alternatively use the

MDT 306 - Torque Wrench Tool VM with Bit

Hexagon Socket (torque 150 – 180 cN.m).

Step 9 (adjust screw)

Turn the adjust screw completely in the direction

“open” using the MDT 327.

Step 10 (fluid box)

Push the fluid box carefully in a 45° angle onto

the valve.

Make sure that the fluid box sits correctly inside

the valve and touches the frame. There will be a

resistance due to a spring inside the valve.

Straighten the fluid box until it latches in.

Optional positions

The bayonet fluid box has three 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. Currently,

no cartridge holder is available for locking

position 1 and 3.

Perform the adjust

You need to perform the adjust now. For details

of the adjust process, see paragraph 6.5,

page 52.

After the adjust is successfully completed,

continue with the following steps.

Step 11 (cartridge holder)

Push the cartridge holder onto the top of the

valve body, so that the two pins of the cartridge

holders sit into the holes of the valve body.

To fix the cartridge holder, screw in the screw of

the cartridge holder (torque 25 – 30 cN.m). You

need the MDT 329 or a Hexagon Key 2 mm.

Depending on the size of the cartridge, you have

to select the correct cartridge holder.

Step 12 (cartridge)

Push the cartridge into the cartridge holder and

screw it onto the fluid box (clockwise).

Step 13 (Adapter for compressed air)

Screw the Adapter for Compressed Air onto the

cartridge (clockwise).

Make sure it sits tightly.
