4 Sewing

4.01 Sewing with bobbin thread monitoring function

The bobbin thread monitoring function via sensor is activated, when parameter
"660" is set at value "1". The number of stitches, which can sewn with the
remaining thread, is entered under parameter "760", after the bobbin thread
monitoring function has responded.
You will find more information about parameter settings in Chapter 5.01

Parameter Settings.

● If, during sewing, the bobbin thread
monitor recognises that the residual
thread supply is being used, LED 1 starts
flashing.
Sewing can continue without a bobbin
change. From this point on the pre-set
number of stitches, which can be sewn
with the remaining thread, are counted.

● Once this number of stitches has been
sewn, the machine stops automatically
and LED 1 lights up permanently. The
bobbin must be changed.
