33.23 Sewing Process Testing Program

With the aid of the "Sewing Process" testing program, the switching
order of the valves can be checked.
This testing program is particularly helpful for the setting of the thread
catcher and the thread trimming systems because one can see precisely
how the individual components lie in regard to the needle thread, looper
thread and the gimp.
Caution Risk of Injury!
The "Sewing Process" testing program serves only for the checking of
cycles and functions. Maintenance or setting work may not be
conducted during the "Sewing Process" testing program.
The testing program can be set to the following values. Depending on
the sewing cycle, interruptions occur at different points.
Inactive = Normal sewing cycle, the testing program is
turned off
Thr. Catcher = The sewing cycle is stopped after the valves of the
thread catcher are switched
Thr. Cutter = The sewing cycle is stopped after the valve of the
respective thread trimming system is switched
T Ca.+T Cu = The sewing cycle is stopped after each valve
is switched
When the sewing cycle is stopped, the following values appear in the
