Mode 7 Overlock Machines
- Signal M1 after stop in position 2 after delay (kd1) during ON period (kt1)
- Signal M2 after stop in position 2 after delay (kd2) during ON period (kt2) or
if parameter 232=1, as fast scissors alternating with M3 (parameter 282=0)
- Chain suction during stitch count (c1) at the start of the seam and stitch counting (c2) at the seam end
- Thread tension release after light barrier uncovered
- Tape cutter at the start of the seam after stitch count (c3) and at the seam end after stitch count (c4) and
the delay time (kd3)
- Sewing foot lifting (see chapter "Sewing Foot Lifting")
- If parameter 018 = 1, parameter 022 must also be set at "1"
- Signal “machine running”
- Signal “machine at standstill”
Mode 8 Backlatch Machines (Pegasus)
- Signal M1 with pedal in positions -1 and –2
- Signal M2 with pedal in positions 1-12
- Inverted signal M3 with pedal in positions 1-12
- Sewing foot lifting (see chapter "Sewing Foot Lifting")
- Signal “machine running”
- Signal “machine at standstill”
- Operation at automatic speed
- Automatic speed has priority over machine run blockage
- Machine run blockage effective with open contact (input in1 / parameter 240=6)
»Automatic speed has priority over machine run blockage«
- Key for operation at automatic speed (input in3 / parameter 242=10)
