Full-auto Teaching
P. 13
This method is used to set the threshold value while the sensing objects are still
moving on the production line, without stopping the production line.
When using 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').

1-level Teaching
P. 14
This sets the shift value to any desired value, and sets the threshold values (1_SL,
2_SL) by means of 1-level teaching.

3-level Teaching
P. 16 l
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'.
