9.23 Bag Sewing Machine Functions (Mode 5)

Function with or without control panel Parameter

Chainstitch machine functions e. g. bag sewing machine functions (Sak) 198

There are various setting possibilities in mode 5 using parameter 198:

198 = 0 Thread trimming or hot thread chain cutting and sewing foot lifting are enabled by means of the pedal.

198 = 1 Thread trimming or hot thread chain cutting is enabled by means of the knee switch, and the sewing foot is lifted

using the pedal.

198 = 2 Thread trimming or hot thread chain cutting is enabled by means of the pedal, and the sewing foot is lifted by

means of the knee switch.

For bag sewing machine operation the parameters indicated below must be adapted manually. See List of Parameters

chapter “Timing Diagrams” mode 5 (bag sewing machine) for the values. For the knee switch select an input in1...i10, and

set the corresponding parameter to “42“.

Function with or without control panel Parameter

Delay time output M2 (kd2) 282

ON period output M2 (impulse) (kt2) 283

Delay time output M3 for hot thread chain cutting (kd3) 284

ON period output M3 for hot thread chain cutting (kt3) 285

Delay time until sewing foot On (kdF) 288

Input for knee switch function (in1...i10) 240...249

9.24 Stitch Lock Machine Functions (Mode 21)

Function with or without control panel Parameter

Stitch lock function On/Off (StL) 196

The following settings are possible using parameter 196:

196 = 0 The stitch lock function is off. Output ST2/34 operates as stitch condensing.

196 = 1 The stitch lock function is on. Output ST2/34 operates as stitch lock and output ST2/28 (M2) as stitch

condensing.

Note that the output functions have been switched! Pay particular attention when connecting a different

sewing machine!

The corresponding values are set automatically in mode 21. See table in chapter “ Preset Values Depending on Mode“.

9.25 Functions for Pegasus MHG-100 Machine (Mode 24)

Function with or without control panel Parameter

Delay time from light barrier uncovered to release of light barrier speed n5 (dnL) 158

Stitch counting until signal M9 Off (cb2) 159

The corresponding values are set automatically in mode 24. See table in chapter “ Preset Values Depending on Mode“.

See timing diagrams in the List of Parameters for functions of this machine model.

9.26 Overlock Machine Functions (Mode 7)

9.26.1 Chain Suction Signal

The chain suction signal can be pre-selected for start and end counting, respectively, using the S2 key on the control and

key 1 on the V810/V820 control panel. If chain suction and tape cutter are switched off at the start of the seam, the

respective counts will be suppressed. But they will be performed at the seam end.
