General
The MICROCONTROL controls of the DÜRKOPP ADLER 975 - 1 - 5 have as an integral part the comprehensive MULTITEST testing and monitoring system.
A microcomputer assumes the control tasks, monitors the sewing procedure and displays operator errors and malfunctions.
Special programs aid in making mechanical settings and make possible a quick inspection of the input and output elements without additional measuring equipment.
Errors and testing results are shown in a 2 x 16-digit display.
During fault-free operation the display shows information to the operating and the sewing sequences.
For program testing and error diagnosis it is possible to blank out the summation counter and to alternatively receive a cycle display of the parallel-operating PROM components for the left and right clamping tables as well as for the sewing process.
With an operator error or a malfunction the function sequence is interrupted. The cause is shown in the display by the appropriate error symbol. In most cases the error symbol disappears after the cause of the error is remedied and the CLEAR key pressed.
In some cases the main switch must be turned off when the error is corrected for safety reasons.
A number of error messages are meant only for the maintenance staff.
All functions can be called up and changed by pressing the appropriate key. The sewing unit must be in its base position for this.
When the sewing unit is turned on the controls conduct a number of self-tests. At this time the program and data memory and the display, among other things, are checked as to fault-free functioning.
After the sewing unit is turned off the set values for the individual functions are stored in the program and data memory (battery buffered) and automatically activated when next turned on again.
ATTENTION !
This short description of the Microcontrol 975 - 1 - 5 is valid for the

“ START ” Key and “ CLEAR ” Key
By pressing the “ START ” key the command for the initial run of the clamping tables is issued after the sewing unit is turned on.
By pressing the “ START ” key a STOP command is cancelled.
By pressing the “ CLEAR ” key slight errors are cancelled after the malfunction has been corrected.
If, after pressing the “ CLEAR ” key, the error message does not disappear, then the service technician must be notified.
3.3
“
Σ
” Key
By pressing the “
Σ
” key the piece count ( in the upper right of the display ) is reset to 0000.
The piece count shows the number of pieces finished since the last reset.
In program 40 the sewing process is activated by pressing the “
Σ
” key, if one of the two clamping tables is in sewing position.
3.4
“ SEAM BEGINNING ” Key
By pressing the “ SEAM BEGINNING ” key the set delay is shown in the display.
With the “ SEAM BEGINNING ” key held down, the delay can be set with the “ + ” and “ - ” keys.
Setting range: 0....600 msec
The set value remains in the memory even after the sewing unit is turned off.

The set value remains stored in the memory even after the sewing unit is turned off.
3.6
“ SEWING SUPPRESSION ” Key
By pressing the “ SEWING SUPPRESSION ” key the cloth can be checked before being swung in for sewing.
By pressing the “ SEWING SUPPRESSION ” key again the function is cancelled.
When the function is active the LED above the key is lit.
3.7
“ DRY RUN / TERMINATE ” Key
By pressing the “ DRY RUN / TERMINATE ” key the clamping table which is next to be swung in for sewing is not sewn ( dry run ).
If sewing is already occuring, then this is interrupted and the thread cut.
When the function is active the LED above the key is lit.
3.8
“ THREADING ” Key
By pressing the “ THREADING ” key the unit is automatically run into the threading position.
The “ THREADING ” key can only be used in program 01 ( sewing ) before a sewing process has been started, this is when the display shows “ PRESS START ”.
Turn the main switch off or press the “ STOP ” key in program 01.
