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 (except sensing output 2) / Hysteresis mode]

3-point teaching [Window comparator mode (except sensing output 2) / Hysteresis mode]
Ɣ
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

TEACHING MODE
Ɣ
Be sure that detection may become unstable depending on the use environ-
ment in teaching if less margin is applied.
Ɣ
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
.”
Ɣ
Teaching can be set in RUN mode.
