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

TEACHING MODE
Ɣ
Be sure that detection may become unstable depending on the use environment
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
