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

The non-observance of the following safety instructions can cause

bodily injuries or damages to the machine.

1. The machine must only be commissioned in full knowledge of the

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

and made only in adherence to all safety regulations.

11. For repairs, only replacement parts approved by us must be used.

12. Commissioning of the sewing head is prohibited until such time as

the entire sewing unit is found to comply with EC directives.

13. The line cord should be equipped with a country-specific mains

plug. This work must be carried out by appropriately trained

technicians (see paragraph 8).

It is absolutely necessary to respect the safety

instructions marked by these signs.

Danger of bodily injuries !

Please note also the general safety instructions.

1. General

This manual contains important information on the safe and correct use

of the “DACIII” (Dürkopp Adler Control) new-generation controller.

Screen images in this brief description

The symbol display on the various screens depends on the sewing

machine’s equipment and settings. The screen images illustrated in

this brief description may therefore not always correspond exactly with

the screens appearing in the controller display.

Operating terminal with graphic user guide

The operating terminal is fitted with an LCD display and a keyboard.

The user guide employs only internationally intelligible symbols,

supplemented with textual information in the selected language. The

various symbols are arranged in groups in the menu structure of the

sewing and test programs.

Simplicity of operation ensures rapid familiarization.

Ease of programming

99 freely programmable pocket programs are available to the user,

which can be combined with any number of seam patterns.

20 pocket sequences.

Each pocket sequence can be composed of a maximum of 8

pocket programs in any order.

On the “slanting-pocket version” of the class 745-34-2 all practical

angles can be programmed by the operator,

who can thus dispense with the need to spend time and effort

readjusting the corner blades and programming seam displacements.

Setting and test programs

The MULTITEST comprehensive testing and monitoring system is

integral to the DACIII control.

A microcomputer carries out the control functions, monitors the sewing

process and displays incorrect operations and faults.

Errors and test results are shown in the LCD display.

If the machine is operating normally the display shows information

relating to operation and sewing.

In the event of an operating error or fault the function sequence is

interrupted. The display indicates the cause by means of the

appropriate error symbol.

In most cases the error symbol disappears once the error has been

rectified.

In some cases the main switch must be switched off for safety reasons

when the error is rectified.

Special programs facilitate mechanical settings and enable receiver

and transmitter elements to be rapidly tested without additional

measuring devices.

Memory dongle

The dongle is used to memorize sewing programs and machine

parameters and to transfer these data to other sewing units.

2. Operating terminal

Data input and output is done via an operating terminal with a colour

LCD display and a multipurpose keyboard.

3. Selecting the language

–Switch on the main switch and keep pressing the “ñ” key or

–Press the keys “RST” and “ñ” in order to activate the language

selection

–The different languages are memorized in the control.

–By pressing the cursor keys “ñ“or”ò” the desired language can be

selected (it will appear white on black).

–With the “F5” key the language that will be activated when

switching on the automat the next time is marked with an asterisk.

4. Memory dongle The dongle is used to memorize sewing programs and machine

parameters and to transfer these data to other sewing units.

The transfer direction is selected with the keys ”F2” and “F4”. The data

transfer is started with the “F5”key.

4.1 Transferring data from the memory dongle to the control

–Use the “ð”or“ï” cursor keys, to select the required parameter

(machine parameter, sequences or seam program).

–The pictogram representing the required parameter will then

appear white on black.

–Start the data transfer by pressing the “F5”key.

F1 F2 F3 F4 F5

4.2 Transferring data from the control to the memory dongle

–When saving data on the dongle, all parameters, machine

parameters, sequences and seam programs are memorized.

–After pressing the “F5” key, appears the question whether the

dongle is to be overwritten.

F1 F2 F3 F4 F5

–The current type of the dongle being plugged in is determined and

indicated on the display.

–Data transfer can be started by pressing the “F5” key and stopped

with the “ESC”key.

–If no data dongle 745-34-2 is indicated but e. g. Boot 745-34-2, the

dongle will first be formatted after pressing the “F5” key before the

data are saved on the dongle.
