1. General
These programming instructions contain important information to the
safe, proper and economical use of the new generation of “DAC”
controls (Dürkopp Adler Control).
Ease of Programming
The user can program 99 freely-programmable programs with up to 13
steps for the left and right piece.
–
Supplementary thread tension as of a specific fullness value.
–
31 fullness values can be selected.
–
Loading of all original parameters (Reset)
–
All base parameters can be set via the keypad.
–
Comprehensive model programming.
–
The sewing drive is controlled directly through the pedal.
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 LCD display. Under normal
working conditions the display shows information to operation and the
sewing process.
When an operating error or a malfunction occurs the functions are
interrupted.
In some cases the main switch must be turned off during error
correction for safety reasons.
A portion of the error messages is 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.
