Parameter Designation Unit max min Preset Ind.
190 MEK Function “unlock the chain” in modes 5, 6, 7 and 16 3 0 1 *) A
(parameter 290)
0 = Unlocking the chain Off
1 = Unlocking the chain manually (with pedal in
pos. –2 without cutting at the seam end)
2 = Unlocking the chain automatically
- by means of light barrier or
- pedal in pos. –2 (parameter 019) without
cutting at the seam end
3 = Unlocking the chain automatically
- by means of light barrier or
- pedal in pos. –2 (parameter 019) with cutting
and run-out stitches (parameter 184) at the
seam end, then unlocking the chain (only if
parameter 290 = 7)
191 MHE Seam end in the overlock mode by end count c2 or c4 1 0 0 A
0 = Seam end after count c4 – tape cutter
1 = Seam end after count c2 – chain suction
192 PLS Speed of the light barrier compensating stitches 1 0 0 *) A
0 = Speed n5 after light barrier sensing
1 = Speed pedal controlled
193 kSL Enable chain suction signal and thread tension release 1 0 0 A
0 = Thread tension release and chain suction after
the light barrier compensating stitches
1 = Chain suction from light barrier uncovered
onwards and thread tension release after the
light barrier compensating stitches
194 Stb Function “blow fabric onto stack” 1 0 0 *) A
(only if parameter 290 = 16)
0 = Blow fabric onto stack at the seam end
1 = Blow fabric onto stack from light barrier
uncovered onwards
195 LSc Stitches for light barrier monitoring stitches 2550 **) 0 0 A
(light barrier monitoring is off, when set to “0”).
196 StL Function “stitch lock” (parameter 290 = 21) 1 0 1 *) A
0 = Stitch lock Off
Output ST2/34 (STV) = Stitch condensing
1 = Stitch lock On
Output ST2/28 (M2) = Stitch condensing
Output ST2/34 (STV) = Stitch lock
Attention! Upon switching the parameter from 0 to 1 or
vice versa, the output function changes accordingly!
198 SAk Functions with chainstitch machines 2 0 0 A
e. g. bag sewing machine (parameter 290 = 5)
0 = Function “thread trimming” or “hot thread chain
cutting” and sewing foot lift using the pedal.
1 = Function “thread trimming” or “hot thread chain
cutting” by means of knee switch and sewing foot lift
using the pedal.
2 = Function “thread trimming” or “hot thread chain
cutting” using the pedal and sewing foot lift by means
of knee switch.
*) Depending on the selected mode. See table at the beginning of the List of Parameters!
**) When programming the 3-digit or 4-digit control parameter values (without control panel), the 2-digit or 3-digit
value displayed must be multiplied by 10.
