22. SENSOR ADJUSTMENT
The presser foot compensating system is activated by a N/C sensor that has to be regulated in
this way:
22.1- Flat sewing
the pressure of presser foot is low.
22.2- Crossing area
In this position the presser foot rises and the detector covers the sensor (image 49.2) activating
it, giving high pressure on the presser foot and after a few stitches also the presser foot point
cylinder will activate.
After crossing the thick area the sensor returns OFF and the pressure of the presser foot LOW.
