Operation
Set the mode selector to TEACH.
Set the NORMAL/ZONE mode selector to NORMAL.
Press the TEACH button with no sensing object
(i.e., teach the background). The teaching indicator (red) will turn ON.
Set the mode selector to RUN.
(Set to L-ON or D-ON mode.)
Operation
Set the mode selector to TEACH.
Set the NORMAL/ZONE mode selector to NORMAL.
Press the TEACH button with a sensing object located at the sensing
position. The teaching indicator (red) will turn ON.
Move the sensing object and press the TEACH button with the back-
ground.

If the teaching is successful, set the mode selector to RUN to complete
the teaching operation.
Set the E3G to light- ordark-ON mode with the mode selectoraccording
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.
ON
If the teaching is successful, the teaching indicator (green) will turn
ON.
Ifthe teaching isnotsuccessful, the teaching indicator(red) will start
to flash.
Threshold a
(La)
Teaching without sensing
objects (i.e., teaching the
background).
Normal one-point teaching
Press the TEACH button
with the background
object.
Threshold (a) is set to a
distance in front of the
background of 20% of the
background distance.
The output is ON between
the Sensor and La.
Background
2. Normal Two -point Teaching
E3G-L/ML
ON
Object
Setting a threshold in the
middle between the
background and sensing
object for operation.
Normal two-point teaching
Press the TEACH button
with the background object
and with the sensing
object.
Threshold (a) is set
approximately in the
middle between the
background and sensing
object.
The output is ON between
the Sensor and La.

Zone teaching
Press the TEACH button
with the background object
(conveyor, etc.).
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.
The output is ON between
La and Lb.
Threshold

ON
Set the mode selector to TEACH.
Set the NORMAL/ZONE mode selector to ZONE.
Press the TEACH button with the background.

Set the mode selector to RUN.
(Set to L-ON or D-ON mode.)
Set the mode selector to TEACH.
Set the NORMAL/ZONE mode selector to NORMAL.
Press the TEACH button for 3 s or more.

If the teaching is successful, set the mode selector to RUN to complete
the teaching operation.
(Set to L-ON or D-ON mode.)
Operation
Operation
Background
The teaching indicator (red) will turn ON first. Then the teaching
indicator (green) will turn ON.
The teaching indicator (red) will turn ON.
The teaching indicator (green) will turn ON in 3 s. This means that
teaching was successful.
OFF
ON
Threshold b (Lb)
OFF
ON
Setting the maximum
sensing distance of the
Sensor.
Maximum distance setting
(in normal mode)
Press the TEACH button
for longer than three
seconds.
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
whenever the sensing
object is located between
the Sensor and at a
distance of 2.2 m.
