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 "PRO MODE OPERATION MANUAL."
● Teaching can be set in RUN mode.
Useful when sensing object can be set
● This is basic teaching method.

1. Press the SET key in the sensing object present condition.
2. Press the SET key in the sensing object absent condition.
Stable sensing is possible
Stable sensing is not possible
Useful when sensing object cannot be set
● This is teaching method in case small object or object in back ground are existing

Note: The shift value of approx. 15% is an initial value. Display of the shift value can be changed to percentage
[approx. 0 to 999% (unit 1 %)] or incident light intensity [0 to 9999 (unit 1)].
For setting the shift amount, refer to "PRO MODE OPERATION MANUAL."
Useful when not want to stop production line and to keep the sensing object move

1. Press the SET key in the sensing
object present condition or non
sensing object present condition.
2. The threshold level is shifted to
high value (low sensitivity) by
pressing down UP key.
The threshold level is shifted to low
value (high sensitivity) by pressing
down UP key.

1-point teaching (Window comparator mode / 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.

1. Pressing SET key down
2. Press the SET key down in the sensing object present condition.
3. The threshold value (1_SL) that is 10% lower from the incident
light intensity and the threshold value (2_SL) that is 10% higher
from the incident light intensity are set. (Note 1, 2)
Stable sensing is possible
Stable sensing is not possible
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 "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 / 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
light intensities are different from each other.

Note: If the value after setting exceeds the maximum (minimum), the maximum (minimum) sensitivity will be set.
3-point teaching (Window comparator mode / 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
light intensities are different.
● 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".

Note: If the value after setting exceeds the maximum (minimum), the maximum (minimum) sensitivity will be set.
Span adjustment in rising differential mode or trailing differential mode
● Press the SET key to confirm the setting item.
● The threshold can be set by using the threshold value fine adjustment function.
