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.

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.
Pressing SET key down
2.
Run the sensing object on the line and hold down the
SET key.

when the sensing object passed through, release the
SET key.
Automatic
Pressing down long
Useful when sensing object can be set
Useful when sensing object cannot be set
This is teaching method in case small object or object in back
ground are existing.
This is method to conduct teaching doing sensing object is
moving.
Useful when not want to stop production line and to keep the sensing object move
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.

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)
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 / 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.
<Hysteresis mode>
1_SL (P-1)
2_SL (P-2)
<Window comparator mode>

1.
Pressing SET key down (1st time)
2.
Press down the SET key in the sensing object present condition.
(2nd time)
Stable sensing is not possible
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
●
Move to the rising differential mode, or the trailing differential mode in the
PRO6 mode, and press the jog switch to confirm the setting.
For the setting
procedure, refer to
<PRO6>
in “
PRO MODE OPERATION MANUAL
.”
● The threshold can be set by using the threshold value fine adjustment function.
For the threshold value fine adjustment function, refer to “
