7 TEACHING MODE
Be sure that detection may become unstable depending on the use environ-
ment in teaching if less margin is applied.
When teaching in Window comparator mode or Hysteresis mode, a setting
has to be made in PRO mode beforehand.
In case 1-point teaching, make sure to set the shift amount. (initial value is
10% or 100)
For the setting, refer to <PRO6> in "PRO MODE OPERATION MANUAL."
Teaching can be set in RUN mode.
2-point teaching This is basic teaching method.

or
Note: The shift value of approx. 15% is an initial value. Display of the shift value can be changed to per-
centage [approx. 0 to 999% (unit 1 %)] or incident light intensity [0 to 9999 (unit 1)].
For setting the shift amount, refer to <PRO1> in "PRO MODE OPERATION MANUAL."

1-point teaching [Window comparator mode (except sensing output 2) / Hysteresis mode]
This is method to set the shift amount to the desired value and to set the
threshold range by using the 1-point teaching.

Notes 1) The shift amount of 10% is an initial value. The shift amount can be set in PRO mode. Furthermore, the shift value
can be set in incident light amount. For setting method, refer to <PRO6> in "PRO MODE OPERATION MANUAL."
2) If the value after setting exceeds the maximum (minimum), the maximum (minimum) sensitivity will be set.
2-point teaching [Window comparator mode (except sensing output 2) / Hysteresis mode]
This is method to set the threshold range by conducting the 2-point teaching (P-1, P-2).
When conducting teaching, use sensing objects (P-1 and P-2) whose incident

3-point teaching [Window comparator mode (except sensing output 2) / Hysteresis mode]
This is the method to conduct the 3-point teaching (P-1, P-2, P-3) and to set the
threshold range by setting the threshold value (1_SL) of the mid-point between "A"
and "B" and the threshold value (2_SL) of the mid-point between "B" and "C".
When conducting teaching, use sensing objects (A, B and C) whose incident
After teaching, P-1, P-2 and P-3 will be automatically relocated in ascending order:
i.e. the lowest value is placed in "A", the second lowest in "B" and the highest in "C".
