TEACH : Teaching Mode
Refer to p.13 ~ for setting procedure
P.13~
1-level Teaching
When using FX-305(P) window comparator mode
The ‘threshold value’ can be set with any of the 3 teaching methods, ‘1-level
teaching’, ‘2-level teaching’ and ‘3-level teaching’. By setting two ‘threshold
values’, both ON and OFF can occur between the two threshold value levels.
This sets the shift value to any desired value, and sets the threshold values (1_SL,
2_SL) by means of 1-level teaching.
P.15~
2-level Teaching
This carries out 2-level teaching (P-1, P-2) and sets the threshold values (1_SL,
2_SL).

0
P.17~
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,
mount to make the threshold values to more than the following values.
STDF mode : 40 digits
LONG mode: 60 digits
U-LG mode : 100 digits
