1. General
The MICROCONTROL controls of the DÜRKOPP ADLER 745-22;-23;
-24 include the integrated comprehensive MULTITEST testing and monitoring system.
A microcomputer assumes the control tasks, monitors the sewing process and signals operating faults and malfunctions.
Special programs facilitate mechanical adjustments and make possible a rapid testing of the input and output elements without additional measuring apparatus.
Errors and test results are shown in a 2 x 16 digit 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 cause is shown in the display by the appropriate error symbol.
In most cases the error symbol will disappear when the cause of the fault has been 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.
All functions can be called up and changed by pressing the appropriate key. The unit must be in its initial position for this.
When the unit is switched on the controls conduct several comprehensive self-tests. Among other things the program and data memories and the display are checked for flawless operation at this time.
After the machine is switched off the set values of the individual functions are stored in the program and data memories (battery buffered) and automatically activated when switched on again.
ATTENTION !
The controls for the Class 745-24 are not compatible with the controls for the Class 745-22;-23.
