Operating Instructions D669 M-TYPE DELTA - 00.0 - 10/2020
5.8.7.1 Setting the Light barrier parameters
The light barrier detects the beginning and the end of the material.
After a signal was detected, sewing can continue automatically
with the specifically set parameters.
Icon Menu item
Distance
Distance from the detection of the signal
to the end of the material.
The distance signifies the path from
the needle to the light barrier. The path
is specified in millimeters and used by
the machine to independently calculate
the number of stitches.
Signal detection at seam
begin
The signal scan of the light barrier is
performed at the beginning of the seam.
If the function is activated, the light
barrier must detect a signal to allow
the machine to sew. If the function is
inactive, sewing can take place without
signal detection.
Signal detection at seam end
The signal scan of the light barrier is
performed at the end of the seam.
If the function is active, the machine will
continue to sew with the specifically
set parameters following the signal
detection. If the function is inactive,
nothing will happen.
Seams
Input of the number of signal detections
after which the machine is supposed
to continue with the specifically set
parameters.
Filter stitches
Loosely woven fabric with stitches may
cause the light barrier to wrongly detect a
signal. To prevent this from happening,
you enter the number of filter stitches.
This number represents the minimum
number of stitches with signal detection
following the 1
st
detection of the signal.
