ATTENTION !

The sewing unit may only be installed by trained personnel.

2.1 Transport Guards

The transport guards are found at the following places:

–Sewing head 1

–Feed and advancing unit 2

–Stacker 3

Removing the transport guards

–Remove the securing bands and wooden laths on the machine

head, machine table and on the stand.

2.2 Aligning the Sewing Unit

The sewing unit can be aligned using the table leg. Care must be

taken to see that the table lies horizontal.

–Place a water level on the stand.

–Loosen screws 1 and 2.

–Align the table top horizontal

–Tighten screws 1 and 2.

2.3 Attaching the Yarn Stand

–Insert the yarn stand 4 into the drilled hole of the yarn stand holder 3.

–Fasten the yarnstand with nuts and washers.

–Mount and align the yarn spool holder and take-off arm as shown

in the illustration.

2.4 Connecting the Vacuum

The vacuum of the feeding device fixes the aligned sewing material.

The feeding device is prepared for connection to an in-house vacuum

facility.

If no in-house vacuum facility exists, then the rotary blower and the

vacuum distributor available as optional equipment must be ordered.

–Connect the suction hose of an in-house vacuum facility or a

vacuum distributor to the suction connexion 3.

2.5 Checking the V-belt Tension

Caution Risk of Injury !

Check the V-belt tension only with the sewing unit turned off.

Checking the V-belt Tension

–It must be possible to press in the V-belt 1 of the sewing drive

approx. 10 mm in the middle with a finger.

Correcting the V-belt tension

–Loosen the nuts 2.

–Adjust the V-belt tension by swinging the sewing drive 3.

–Tighten the nuts 2.

3. Electrical Connection

ATTENTION !

All work on the electrical equipment of the sewing unit may only be

performed by electricians or appropriately instructed persons.

The mains plug must be pulled out.

It is essential that the enclosed operating instructions of the sewing

drive and the servo-motor manufacturers be observed!

3.1 Mounting the Control Panel

–Push control panel 2 with the two clamping pieces 3 onto bar 4.

–Set the angle of the control panel.

–Tighten the screws on the two clamps 3.

–Loosen the clamping screw 5.

–Turn the control panel so that the operator has an optimum view of

the display.

–Tighten the clamping screw 5.

–Carefully insert the connection plug 1 into the socket in the back of

the control panel.

–Tighten the screws of the connection plug.

3.2 Checking the Nominal Voltage

3 - 2: 190 V

3 - 1: 200 V

4 - 2: 210 V

4 - 1: 220 V

5 - 2: 230 V

5 - 1: 240 V

5 4 3 2 1

230 V

ATTENTION !

The nominal voltage listed on the ratings plate of the sewing drive and

the mains voltage must correspond!

An adaption to the local mains voltage occurs via the terminals 1 to 5

on the transformer 1 of the sewing drive.

At delivery, the sewing drive is set to a mains voltage of 230 V

(terminals 5 and 2).

–Check the arrangement of the connections on the transformer of

the sewing drive.

–Change the connections to correspond to the existing mains

voltage, if necessary.

The direct currect sewing drives used are operated with a "single

phase-alternating-voltage".

In order to avoid overloading a single phase of a threephase mains

supply when connecting multiple sewing units, the following is to be

observed:

–The connections of the individual sewing units must be distributed

equally to the phases of the threephase mains supply.

–The wiring for connection to a threephase mains supply is shown

in the construction circuit diagram.

4. Pneumatic Connection

4.1 Connecting the Compressed Air Maintenance Unit

For operation of the pneumatic components, the sewing unit must be

supplied with water-free compressed air.

ATTENTION !

For a flawless functioning of the pneumatic control procedures the

compressed air supply must operate as follows:

The compressed air supply must be so that even at the moment of

greatest air consumption the minimum operating pressure may not

drop below 5 bar.

The pneumatic system of the sewing unit must be supplied with

water-free compressed air.

The line overpressure must be between 8 to 10 bar.

–Connect the compressed air maintenance unit to the in-house

compressed air supply with connection hose 1 ( Ø = 9 mm) and the

hose coupling G1/4.

Pneumatic connections package

A pneumatic connections package for stands with compressed air

maintenance unit and pneumatic optional equipment is available under

order no. 0797 003031.

The connections package contains the following components:

–Connection hose, 5m long, Ø = 9 mm

–Hose nozzles and hose clamps

–Coupling socket and coupling plug

4.2 Setting the Operating Pressure

The operating pressure of the sewing unit is 6 bar.

It can be seen at manometer 2.

–To set the operating pressure pull up knob 1 and turn.

Turn clockwise = Increase pressure

Turn counterclockwise = Reduce pressure

5. Refilling the oil

Caution Risk of Injury !

Oil can cause skin rashes.

Avoid longer skin contact.

After contact wash yourself thoroughly.

ATTENTION !

The handling and disposal of mineral oils is subject to legal constraints.

Deliver used oil to an authorized reception point.

Protect your environment.

Take care nicht to spill any oil.

For filling the oil reservoir use only ESSO SP-NK 10 lubricating oil or

an equivalent oil with following specification:

–Viscosity at 40 °C: 10 mm2/s

–Flashpoint: 150 °C

ESSO SP-NK 10 is available from DÜRKOPP -ADLER AG sales

offices under the following parts no.s:

–2 liter container: 9047 000013
