Foreword

This instruction manual is intended to help the user to become familiar

with the machine and take advantage of its application possibilities in

accordance with the recommendations.

The instruction manual contains important information on how to

operate the machine securely, properly and economically. Observation

of the instructions eliminates danger, reduces costs for repair and

down-times, and increases the reliability and life of the machine.

The instruction manual is intended to complement existing national

accident prevention and environment protection regulations.

The instruction manual must always be available at the machine/sewing

unit.

The instruction manual must be read and applied by any person that is

authorized to work on the machine/sewing unit. This means:

–Operation, including equipping, troubleshooting during the work

cycle, removing of fabric waste,

–Service (maintenance, inspection, repair) and/or

–Transport.

The user also has to assure that only authorized personnel work on the

machine.

The user is obliged to check the machine at least once per shift for

apparent damages and to immediatly report any changes (including the

performance in service), which impair the safety.

The user company must ensure that the machine is only operated in

perfect working order.

Never remove or disable any safety devices.

If safety devices need to be removed for equipping, repairing or

maintaining, the safety devices must be remounted directly after

completion of the maintenance and repair work.

Unauthorized modification of the machine rules out liability of the

manufacturer for damage resulting from this.

Observe all safety and danger recommendations on the machine/unit!

The yellow-and-black striped surfaces designate permanend danger

areas, eg danger of squashing, cutting, shearing or collision.

Besides the recommendations in this instruction manual also observe

the general safety and accident prevention regulations!

General safety instructions

instruction book and operated by persons with appropriate training.

2. Before putting into service also read the safety rules and

instructions of the motor supplier.

3. The machine must be used only for the purpose intended. Use of

the machine without the safety devices is not permitted. Observe all

the relevant safety regulations.

4. When gauge parts are exchanged (e.g. needle, presser foot, needle

plate, feed dog and bobbin) when threading, when the workplace is

left, and during service work, the machine must be disconnected

from the mains by switching off the master switch or disconnecting

the mains plug.

5. Daily servicing work must be carried out only by appropriately

trained persons.

6. Repairs, conversion and special maintenance work must only be

carried out by technicians or persons with appropriate training.

7. For service or repair work on pneumatic systems, disconnect the

machine from the compressed air supply system (max. 7-10 bar).

Before disconnecting, reduce the pressure of the maintenance unit.

Exceptions to this are only adjustments and functions checks made

by appropriately trained technicians.

8. Work on the electrical equipment must be carried out only by

electricians or appropriately trained persons.

9. Work on parts and systems under electric current is not permitted,

except as specified in regulations DIN VDE 0105.

10. Conversion or changes to the machine must be authorized by us

Technical specifications

The sewing unit is driven by a positioning drive.

With the control unit DACIII are operated apart from the sewing drive

also two step motors needed for the X and Y motions of the seam

geometry and a Z axis for the adjustment of the sewing foot.

The arm shaft of the sewing unit is directly driven by a brushless DC

motor.

·Central oil wick lubricating for the machine head and the hook.

·Equipped with a vertical hook

·The BFT graphical control panel OP 7000 serves as control

element.

With electronic needle thread monitor.

In order to generate a clean seam pattern, the sewing unit is equipped

with a multiple thread tension device, permitting to assign to various

thread pulling directions the according tension value previously saved

in the sewing program.

The thread pulling device allows pulling the needle thread under the

sewing material during the first stitch.

The sewing unit is equipped with a programmable stitch counter for

the hook thread monitoring and a piece counter.

Integrated test and check program for service and maintenance

works. In addition to the monitoring of the sewing process, it is also

possible to check the motor functions, the inputs and outputs for the

reference switches, the valves and the feeding motors. The program

also serves for the adjustment of machine functions and the preparing

of sewing programs by the teach-in method.

Individual stitch parameter per stitch in order to control external units

like:

·The stroke position of the presser foot, thread trimmer, thread

clamp,

·Speed, thread tension etc.

The height of the stand can be adjusted with the telescoping feet from

a minimum work height of 760 mm to a maximum work height of 910

mm for stand-up working.

The foot pedal needed to operate the sewing unit can be shifted to

allow an ergonomic adaption to the operator.

2 Designated Use

The class 911 is a sewing unit that is designated for the sewing of

light to medium-heavy material. Such material is generally made of

textile fibers, composite materials but it may also consist of leather.

Suchlike material is used in the clothing industry and for domestic and

motor-vehicle upholstery.

This sewing unit can also be used to produce so-called technical

seams. In this case however, the operator must assess the possible

dangers which may arise (DÜRKOPP ADLER AG will be happy to offer

its assistance), since such applications are relatively rare and at the

same time can be so varied that no single set of criteria can cover

them all. The outcome of this assessment may require appropriate

safety measures to be taken.

Generally only dry material may be sewn with this sewing unit. The

material may be no thicker than 4 mm when compressed by the

lowered workclamp. The material may not contain any hard objects.

The seam is generally produced with textile-fibre sewing thread

(cotton threads, synthetic yarns of covering yarns) with the following

dimensions:

Class 911 thread thickness 15/3 - 120/3

Before using any other thread the possible dangers arising have to be

assessed and appropriate safety measures if necessary taken.

This sewing unit may be set up and operated only in dry,

well-maintained premises. If the sewing unit is used in

premises which are not dry and well-maintained it may be

necessary to take further precautions which should be agreed in

advance (see EN 60204-31:1999).

As manufacturers of industrial sewing machines we proceed on the

assumption that personnel who work on our products will have

received training at least sufficient to acquaint them with all normal

operations and with any hazards which these may involve.
