7-5. Active-presser multi-layered section detection function
7-5-1. Multi-layered section detection function
This function allows detection of a multi-layered section of material. When a multi-layered section of material
is detected, the sewing parameter is automatically changed to the one-touch changeover parameter ("4-2-
9. One-touch utility changeover function" p.50) to allow the sewing machine to continue sewing. The
multi-layered section detection setting can be stored in memory on a pattern-by-pattern basis.
Detectable material thickness : Max. 10 mm
Detection resolution : 0.1 mm
* Multi-layered section of material that is less than 2 mm in thickness is likely to be affected by the feed dog
height. Stable detection, therefore, cannot be carried out. It is not possible to detect two or more multi-lay-
ered sections thickness of which are different. In this case, the one-touch changeover function by means
of the hand switch should be used.
* The multi-layered section detection function is disabled while the one-touch changeover function by
means of the hand switch is carried out.
[In order to detect a multi-layered section]
1. Select enable/disable of the multi-layered
section detection function.
1) Press ❶.
The "sewing data edit screen" is displayed.

2) Press ❷.
The "multi-layered section detection sensor
value screen" is displayed.
3) Enable the multi-layered section detection
function by pressing ❸. (This switch
has been factory-set to OFF at the time of
shipment.)
Set a "threshold" for the multi-layered sec-
tion detection using multi-layered section
height teaching function ❹.
* For the purpose of the multi-layered section
detection function, the word "threshold"
means the value at which the multi-layered
section sensor reacts.
Initial value MAX : 3000
MIN : 1000
