1.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

Dials b401 and b402

With these switches the sewing rpms for the sewing of the house-shaped seam ( b401 ) and for sewing at maximum rpm ( b402 ) are set.

Switch position	Sewing rpm
0	960 min-1
1	1 280 min-1
2	1 700 min-1
3	2 260 min-1
4 - 9	3 000 min-1

2.3 Display

The Microcontrol controls are equipped with a 2 x 16-digit display.

It shows program numbers, piece counts, status reports, error messages, seam beginning delay, among other items.

The sewing unit is ready for operation when the prompt to press the “ START ” key appears in the display.

Example 1:

P01 = Program number

1234 = Piece count

OK	= Status report

Example 2:

P01	= Program number

L07R00Z03 = Program cycle

ERROR 01 = Error message

	Example 3:
	P01	= Program number
	1234	= Piece counter
	Begin: 600 msec	= Seam beginning delay

3.Description of the Keys

3.1 “ STOP ” Key and “ O ” Key

By pressing the “ STOP ” key all current procedures of the sewing unit and the clamping tables are immediately interrupted.

By pressing the “ STOP ” key the sewing, aid and testing programs set with the “ PROGRAM ” switch are activated.

By pressing the “ O ” key the selected output and input elements or the front panel elements in the various testing programs are activated.

3.2 “ 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.
