1. General

These programming instructions contain important information to the

safe, proper and economical use of the new generation of "

DAC

"

(Dürkopp Adler Control) controls.

Display illustrations in these Programming Instructions

The display of the symbols in the various screens is dependent on the

settings, the subclass and the equipment of the sewing unit.

The monitor illustrations in these Programming Instructions must thus

nicht always correspond exactly to the displays shown in the monitor

of the control unit.

Operator terminal with graphical user guidance

The operator terminal is equipped with a LCD monitor and a keypad.

The user guidance occurs exclusively through internationally

understood symbols. The various symbols are combined into groups

within the menu structure of the sewing and testing programs.

The ease of use makes possible short training times.

Ease of programming

The user can enter 99 freely-programmable sewing programs.

6 buttonhole sequences are available for the sewing of sequences.

Each buttonhole sequence can be made up of a maximum of 3

buttonhole programs combined in any order desired.

Setting and testing programs

The

DAC

includes the integrated comprehensive

MULTITEST

testing

and monitoring system.

A microcomputer assumes the control tasks, monitors the sewing

process and signals operating faults and malfunctions.

Errors and test results are shown in a LC display.

Under normal working conditions the display shows information to

operation and the sewing process.

When an operating error or malfunction occurs, the functions are

interrupted. The display shows the cause through the corresponding

error symbol.

In most cases the error symbol disappears after the error cause is

remedied.

In some cases the main switch must be turned off during error

correction for safety reasons.

A portion of the error messages are meant only for the service

personnel.

Special programs facilitate mechanical adjustments and make

possible a rapid testing of the input and output elements without

additional measuring apparatus.

RAM memory card

The RAM memory card serves for the long-term storage of all

programmed data.

They allow the data to be transfered to other sewing units.

The controls tranmit the data to the memory card.

The stored data can again be loaded from the memory card into a DAC

control.

This procedure can be repeated as often as desired within the storage

period of the memory card (approx. 4 years).

3. Memory Card

3.1 Storing and Loading of Programs

The memory card (RAM card) serves for the long-term storage of

sewing programs.

With its help sewing programs and machine parameters can be

transfered to other sewing units.

–

After the

loading

of data, press the "

STOP

" key.

The controls are reinitialized.

This is necessary because new machine parameters are also

loaded when loading programs.

3.2 Replacing the Battery of the Memory Card
