The 'threshold value' can be set with any of the 3 teaching methods, '1-level
teaching', '2-level teaching' and '3-level teaching'.

1-level Teaching
This sets the shift value to any desired value, and sets the threshold values (1_SL,
2_SL) by means of 1-level teaching.

2-level Teaching
This carries out 2-level teaching (P-1, P-2) and sets the threshold values (1_SL,
2_SL).

3-level Teaching
This carries out 3-level teaching (P-1, P-2, P-3) and sets the threshold value
(1_SL) between A and B and the threshold value (2_SL) between B and C as
shown in the diagram below.
After teaching, P-1, P-2 and P-3 are automatically assigned in ascending order to
'A', 'B', and 'C'.

When using FX-305(P) differential mode
Sensing of only sudden changes in incident light intensity is carried out, so that
this is ideal for sensing edges of object such as glass.
Set to 'full-auto teaching' if teaching is to be carried out. (Refer to p.12 for details.)
Furthermore, if the response time has been set in STDF, LONG or U-LG mode,

•
STDF mode : 40 digits
•
LONG mode: 60 digits
•
