1. General
The DÜRKOPP ADLER 743-121 controls, with the int egrat ed MU LTITEST testing and monitoring system, assumes control and supervision
of the sewing process. Operating errors and malfunctions are displayed.
Special programs simplify mechanical adjustments and allow a quick
checking of the i np ut an d o ut pu t e le me nt s.
The data is sh own i n a 2 • 16-digit display.
All functions c an be al te r ed by pres sin g th e ap pr o priate button. The
