● Mounting the sensor to a wall
•
Mount the product as follows, so
that the multiple light reflections
on the wall do not emit to the light-
receivingpart.Whenthereection
factor on a wall is high, it is effec
-
tive to use a dull black color.

Sensing object
1. Press the TEACH key in the background present condition or the
sensing object present condition.
2. When an object in the background is used as a reference, press the
UP key to set the threshold on the sensor side.
When a sensing object is used as a reference, press the DOWN
key to set the threshold on the sensing object side.
3. Teaching is completed.
Automatic
1-point teaching (Window comparator mode)
● This is mode is used for setting the threshold range for the distance from the ref-
erence value of the sensing object, by performing 1-point teaching. This mode is
used for sensing within the threshold range.
● When performing 1-point teaching (window comparator mode), preset “Window
comparator mode 1” in the sensing output setting of the PRO mode. For the set-
ting method, refer to “
12
PRO MODE SETTING.”

his is method to set the threshold range by conducting the 2-point teaching.
● When performing 2-point teaching (window comparator mode), preset “Window
comparator mode 2” in the sensing output setting of the PRO mode.
For the setting, refer to
“
12
PRO MODE SETTING.”
● When conducting teaching, use sensing objects (P-1 and P-2) whose distance are
different from each other.

3-point teaching (Window comparator mode)
●
This is the method to perform 3-point teaching (P-1, P-2, P-3) and to set the threshold range
by setting threshold 1_SL in the mid-point between the 1st time and 2nd time, and threshold

● When performing 3-point teaching (window comparator mode), preset “Window
comparator mode 3” in the sensing output setting of the PRO mode.
For the setting, refer to
“
12
PRO MODE SETTING.”
●
When performing teaching, use sensing objects (P-1, P-2, P-3) with different distance.
●
After teaching, P-1, P-2 and P-3 will be automatically rearranged from the smaller value.
