1. Programming of 739

1.1 Introduction

This programming manual includes instructions for the safe and
economical handling of the new “DAC” (Dürkopp Adler Control) control
system.

Programming convenience

The following functions must be programmed by the user.
–

Display/delete piece counter

–

Sewing motor speed

–

Stitch length

–

Initial bartack

–

Final bartack

–

Initial stitch condensation

–

End stitch condensation

–

Switch thread monitor on/off

Setting and test programmes

The DAC includes the comprehensive functions of the
MULTITEST testing and monitoring software.

The system is controlled by a microcomputer, which also monitors the
sewing process and indicates incorrect operation and errors.

Errors and test results are displayed on a 8-digit LED display with 7
segments. During normal operation, the display shows data regarding
the operation of the unit and the sewing process.

If an error occurs in the operation or the sewing process, the current
function is terminated.

In certain cases the main switch must be switched off in order to
eliminate an error for safety reasons.

Certain error messages are designated for service personnel only.

Special programmes simplify the mechanical configuration and
make it possible to quickly check input and output components without
the need for additional measuring devices.

2.6 Dacs739 tutorial

2.6.1 Creation of a seam contour

“Standard" toolbar

This practical tutorial allows you to familiarize yourself with the
Dacs739 software within a very short time. It covers all the basic steps
that must be carried out for the creation and archiving of your own
individual contours.

The tutorial includes additional information on any given topic and
indicates, where the respective chapter can be found in the online help
facility of Dacs739.

Dacs739 support multi-tasking so that several documents can be
processed simultaneously.

–

Start the Dacs739 software
(see chapter 2.4).
The programme window is opened.

–

Select “File > New”.

The document window is divided into two parts.

To the left, a tree diagram is displayed, showing the sections of the
seam contour. To the right, a CAD design window for the seam contour
to be drawn is displayed.

Below the menu bar, the “standard” toolbar is displayed, while the
“drawing” toolbar is located to the right. At the bottom of the screen,
the “status bar” is displayed.

Menu bar “Drawing” toolbar

The zero point P0 is the origin of the coordinates system. It is always
located in the bottom left corner of the CAD window. The coordinates
run from this point, increasing upwards and to the right.

Additional information

For more information, click the object you would like to know more
about in the diagram.

Import of background pictures

Depending on the application, (waistband extension or flap), a
background picture can be imported.

This background picture is very helpful for the entry of the seam
contour.

–

Open “File > HPGL import”.

–

Select a file:

flap_pattern.plt for the entry of a flap pattern

bottom seam start/end

or

waist-band_pattern.plt for the entry of a waistband extension.

Entry of the seam contour

The following exercise introduces you to the entry of a seam contour
for a curved flap.

The seam contour is entered as a line, i.e. the starting point of a
segment corresponds to the end point of the preceding segment.

When a segment is deleted, its starting point becomes the starting
point of the following segment.

When a segment is inserted, the next existing segment is divided into
two segments of straight lines.

The segment type (straight, arc of circle) can be modified at a later
stage.

–

Select “Tools > Settings".

–

Activate the “Direction” option in the dialog.

–

Activate the “Grid” option.

–

Enter 5.0 mm for “Width” and “Height” respectively.

–

Click the left mouse button.
The starting coordinate is entered.

–

Drag the mouse pointer vertically upwards to pointX=50/Y=85.

Generation of mirrored seam segments or flaps

For symmetrical seam courses, you have the option to mirror individual
seam segments to a centred line. The second half of a symmetrical
seam curve can thus be generated with ease.

If a diagonal flap has been entered, the entire flap can be mirrored.

Calculation of seam template

The seam template is calculated automatically by the system. You
have however the option to subsequently modify the template.

–

Select “Objects > Calculate seam template” from the menu bar.
The template is calculated and displayed in the CAD window.
The tree structure is extended by the individual segments of the
template.

Note

All template segments can be individually modified in the properties
dialog.

4-45

Calculation of fullness contour

The fullness contour is also calculated automatically by the system.
You have the option to subsequently modify the template.

Select “Objects > Calculate fullness template” from the menu bar.
The template is calculated and displayed in the CAD window.
The individual segments of the pattern are added to the tree structure.

File properties

For every document, you have the option to save additional
information. This simplifies the file management.

–

Select “File > File properties”.

–

Enter your details in the available fields.

Saving of seam contour

–

Select “File>Save as”.
The “DACS739\Documents” folder is opened automatically.

–

Enter a name for your seam contour in the “File name” field.
(Example: Seam contour 1)

–

Click the “Save” button.

4-46

Data transfer to the transponder

Seam contours, material clamp contours and fullness contours can be
transferred individually to the transponder in the “Material clamp zero
point” gauge. The “Material clamp zero point” gauge is included in the
delivery.

You have thus the option to transfer individual contours to the stitching
plate, where they can be controlled and processed.

–

Connect the transponder to your PC
see operating instructions of the transponder).

–

Place the “Material clamp zero point” gauge with the respective
transponder onto the transponder device.

–

Select “File > Transponder”.

–

According to your needs, select:

Transfer seam data, or
Transfer template data, or
Transfer fullness data.

The selected data is transferred to the transponder in the gauge.

4-47

Sample flaps and waistband extensions

In the “Documents” inventory of Dacs software, various sample files for
flaps and waistband extensions are saved.
These samples can be modified.

Caution!

Prior to modification, save the sample files under a different name.

Congratulations!

You have reached the end of this tutorial. Please remember that more
