1-point teaching in window comparator and hysteresis mode
With this method, you set the threshold range by setting the shift amount
to the desired value and measuring the incident light intensity once. The
shift amount will be added to the incident light intensity to provide the upper
threshold respectively subtracted from the incident light intensity to provide
the lower threshold.

For FX-502□, window comparator mode only works for sensing
output 1.

Shift amount. The shift amount is 10% by default and can be set in PRO
mode as a percentage or as the incident light intensity. If you select a
incident light intensity setting that exceeds the maximum or minimum, the
maximum or minimum sensitivity will be set automatically.
1. Press the SET key when no sensing object is
present.
2. Press the SET key when the sensing object is
present.
This sets the lower threshold 1_SL at 10%
(the set shift amount) lower than the incident
light intensity and the upper threshold 2_SL at
10% higher than the incident light intensity.

2-point teaching in window comparator and hysteresis mode
With this method, you set the threshold range by performing teaching the
with two sensing objects with different incident light intensities (P‑1 and
P‑2).

3-point teaching in window comparator and hysteresis mode
With this method, you set the threshold range by performing teaching with
three sensing objects with different incident light intensities (P‑1, P‑2, and
P‑3). After you have performed teaching, the three points P‑1, P‑2, and P‑3
will be sorted in ascending order into the values A, B, and C. The threshold
range will be calculated from A, B, and C as follows: The lower threshold
value 1_SL is the midpoint between A and B and the upper threshold value
2_SL is the midpoint between B and C.
