Main switch S0 on
-
If the START button S4 is pressed, the carriage moves to basic position. At the
same time the plunger is raised (1V1 on). Once the basic position is reached (S3
opens contact) the yellow light L2 goes out and the plunger goes up again (1V1
off).
Sequence continues at point “4.13.2 Close clamping device, lapel part is

If the carriage is already in its basic position after power on, the start
commences as described under point “4.13.2 Close clamping device, lapel part is
4.13.2
Close clamping device, lapel part is inserted
By pressing the S4 START button , the clamping device and rear differential transport
are closed when the 1V2 solenoid switches on.
The position of the clamping device is monitored by the light barrier S8-1.
Sequence continues at point “4.13.3 Start of the automatic sewing process”.
4.13.3
Start of the automatic sewing process
The automatic sewing mode can be started by pressing the START button S4 again.
Once start is enable by the S8-1 light barrier (“light”, high signal), the plunger is lifted
and the first side transport is run when the 1V1 solenoid switches on. The material is
now ready for the first stitch. The thread brake is closed. The carriage is now driven in.
Once the lapel edge has been reached – identification by light barrier S8 (“dark”, low
signal) – the carriage is stopped after completing the reverse stitches “Stc1”.
Sequence continues at point “4.13.4 Retraction of the carriage (only once after the
