6.27.3 Reflection Light Barrier LSM001A
Sensitivity setting:
Set minimum sensitivity depending on the distance between light barrier and reflection area (turn potentiometer as far as
possible to the left).
Potentiometer directly on the light barrier module
Mechanical orientation:
Orientation is facilitated by a visible light spot on the reflection area.
6.27.4 Automatic Start Controlled by Light Barrier
Functions Parameter
Delay of automatic start (ASd) 128
Automatic start On/Off (ALS) 129
Light barrier sensing uncovered (LSd) 131
Start of sewing blocked with light barrier uncovered (LSS) 132
This function enables an automatic start of the sewing operation as soon as the light barrier senses the insertion of fabric.
Prerequisites for the operation:
Parameter 009 = ON (light barrier On).
Parameter 129 = ON (automatic start On).
Parameter 131 = ON (light barrier sensing uncovered).
Parameter 132 = ON (no start of sewing with light barrier uncovered).
The pedal must be kept pressed forward at the seam end.
For safety reasons this function is enabled only after a normal start of sewing. The light barrier must be covered as long as
the pedal is in position 0 (neutral). Then press the pedal forward. This function is disabled when the pedal is no longer
pressed forward after the seam end.
6.27.5 Light Barrier Filter for Knitted Fabrics
Functions Parameter
Number of stitches of the light barrier filter (LSF) 005
Light barrier filter On/Off (LSF) 130
Light barrier sensing uncovered or covered (LSd) 131
The filter prevents premature enabling of the light barrier function when sewing knitted fabrics.
Enabling/Disabling of the filter using parameter 130
The filter is not active if parameter 005 = 0
Adaptation to the mesh is possible by varying the number of filter stitches.
Knitted fabric sensing with light barrier uncovered covered, if parameter 131 = OFF
Knitted fabric sensing with light barrier covered uncovered, of parameter 131 = ON
6.28 Needle Up/Down / Single Stitch
The needle up/down or single stitch function can be activated using the keys on two different inputs and selected using
separate parameters.
Mode for the key connected to connector A/6
Functions Parameter
Functions of the key on socket A/6 (nh1) 140
Functions of the key on socket D/1 (nh2) 144
1 = Needle up
2 = Needle up/down
3 = Single stitch
4 = Single stitch with stitch length switching (normal stitch length)
5 = Needle up if outside position 2 or reverse position
6 = Machine stop in position 2
