11.32.3
Reflection Light Barrier LS002
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.

Light Barrier Monitoring
Function
with
or
without
control panel
Parameter
Stitches for light barrier monitoring
(LSc)
195
In order to check the optical and electrical function it is possible to select a number of stitches by means of parameter 195.
While these stitches are performed, the light barrier must be activated at least once. When the count is completed and the
light barrier has not been activated, the drive stops and the message A6 appears.
!
Select a number of stitches that is larger than necessary for the seam.
!
The function is off if the number of stitches is “0“.

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 = 1
(light barrier On).
!
Parameter 129 = 1
(automatic start On).
!
Parameter 131 = 1
(light barrier sensing uncovered).
!
Parameter 132 = 1
(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.

Light Barrier Filter for Knitted Fabrics
Function

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 by means of parameter 130
!
The filter is not active if parameter 005 = 0
!
Adaptation to the mesh is possible by varying the number of filter stitches.
