Adjustment Steps
1 Install, wire, and turn ON the Sensor .
2 Perform sensitivity adjustments (teaching). Refer to Distance Setting (T eaching) below .
3 Check that the mode selector is set to RUN.
Distance Setting (Teaching)
Select the most appropriate teaching method in reference to the following descriptions.
Application
Teaching
Set threshold
Output ON range
Teaching without sensing objects
(i.e., teaching the background).
Detection of glossy objects in front
of the background.
Setting a threshold in the middle
between the background and
sensing object for operation.
Setting the maximum sensing
distance of the Sensor.
Normal one-point teaching
Zone teachingNormal two-point teaching
Maximum distance setting
(in normal mode)
Threshold (a) is set to a dis-
tance in front of the back-
ground of 20% of the back-
ground distance.
Thresholds (a and b) are set in the
sensing distance on condition that the
difference between these thresholds
are approximately 10% of the whole
sensing distance.
Threshold (a) is set approximately
in the middle between the back-
ground and sensing object.
The threshold is set so that the
stability indicator will turn ON at
approximately 2 m if the sensing
object is white paper.
The output is ON between
the Sensor and La.
The output is ON between La and Lb.
The output is ON between the
Sensor and La.
The output is ON whenever
the sensing object is located
between the Sensor and at a
distance of 2.2 m.
La: Distance equivalent to threshold (a)
Lb: Distance equivalent to threshold (b)

Maximum Distance Setting (in Normal Mode)
1. Set the mode selector to TEACH.
2. Set the NORMAL/ZONE mode selector to NORMAL.
3. Press the TEACH button with a sensing object located at the sensing
position. The teaching indicator (red) will turn ON.
4. Move the sensing object and press the TEACH button with the back-
ground.
• If the teaching is successful, the teaching indicator (green) will turn
ON.
• If the teaching is not successful, the teaching indicator (red) will start
to flash.
5. If
the teaching is successful, set the mode selector to RUN to complete
the teaching operation.
Set
the E3G to light- or dark-ON mode with the mode selector according
to the application.
If the teaching is not successful, change the set distance and object
sensing position and repeat two-point teaching from step 3.
Operation
1. Set the mode selector to TEACH.
2. Set the NORMAL/ZONE mode selector to ZONE.
3. Press the TEACH button with the background.
• The teaching indicator (red) will turn ON first. Then the teaching
indicator (green) will turn ON.
4. Set the mode selector to RUN.
(Set to L-ON or D-ON mode.)
Operation
Note: Perform zone teaching with the background.
Operation
1. Set the mode selector to TEACH.
2. Set the NORMAL/ZONE mode selector to NORMAL.
3. Press the TEACH button for 3 s or more.
• The teaching indicator (red) will turn ON.
• The teaching indicator (green) will turn ON in 3 s. This means that
teaching was successful.
4. If
the teaching is successful, set the mode selector to RUN to complete
the teaching operation.
(Set to L-ON or D-ON mode.)
1. Set the mode selector to TEACH.
2. Set the NORMAL/ZONE mode selector to NORMAL.
3. Press the TEACH button with no sensing object
(i.e., teach the background). The teaching indicator (red) will turn ON.
4. Set the mode selector to RUN.
(Set to L-ON or D-ON mode.)

Setting
method
Press the TEACH button for
longer than three seconds.
Press the TEACH button with the
background object (conveyor
, etc.).
Press the TEACH button with the
background object and with the
sensing object.
Press the TEACH button
with the background object.
