include the integrated comprehensive

monitoring system. A microcomputer assumes the control tasks, monitors the sewing

process and s i gn al s o pe rating faults an d m al f un c ti o ns. Special programs facilitate mechanical adjustments and make

possible a ra pi d te s ti n g o f t he input and output elements wi th ou t additional m ea s ur i n g a pp ara tus.

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 sho wn i n t he di s p l ay b y t he app rop r i at e err o r 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 uni t i s s w i tc h ed on th e c o nt r ol s c o nd uc t s ev e ral comprehensive self-tests. Among other things the program and data memories and the display are checked for flawless operation at this time.
