JOPERATING PROCEDURE
Adjustment Steps
1. Install, wire, and turn ON the E3M-V.
2. Perform teaching (mark registration). Refer to Mark Registration (Teaching).
3. Make fine adjustments of the threshold level if necessary. Refer to Threshold Level Adjustments.
4. Check that the mode selector is set to RUN.
Mark Registration (Teaching)
Refer to the following for ideal teaching.
Application
The base has a
color pattern. The
mark and base are
clearly different in
color.
The base has no
color pattern. The
mark and base are
slightly different in
color.
The base has no
color pattern.
Remote teaching
with no positioning
is desired.
One-point teaching Two-points
teaching
Auto-teaching
The default level is
set and the output
is ON when the
mark is detected.
The threshold level
is set between the
color of the mark
and base. The
output is ON when
the mark is
detected.
The threshold level
is set between
color of the mark
and base. The
output is ON when
the mark (i.e., the
color with shorter
passing time) is
detected.
Refer to the following for each teaching method. Remote one- or
two-point teaching is possible. Refer to Remote Control Function.
One-point Teaching
1Set the mode selector to TEACH.
2Locate the mark to the sensing position and press the SET
button. Then all the red threshold indicators are ON.

3Set the mode selector to RUN. The output will be ON
whenever the set mark is detected.
Note: By teaching on the base, reversed output as shown above
(base: ON, mark: OFF) can be obtained.
Two-point Teaching
1Set the mode selector to TEACH.
2Locate the mark to the sensing position and press the SET
button. All the red threshold indicators will turn ON.

is no difference in incident.

4If teaching is successful, set the mode selector to RUN to
complete the teaching operation. If teaching is
unsuccessful, restart from the above step 2.
Note: Follow the above steps so that the output will be turned
ON whenever the mark is detected. By taking the opposite
steps, the output will be turned OFF whenever the mark is
detected and turned ON whenever the base is detected.

JADJUSTMENT STEPS
Auto-teaching
1. Check that the mode selector is set to either RUN or ADJUST.
2. Input a 0.9-s pulse signal into the remote control I/O terminal. (See Note.)
3. Auto-teaching starts when the mark is moved. When the mark passes six times, auto-teaching completes.
If teaching is successful, answer-back output from the remote control I/O terminal will turn ON for 0.3 s.
If teaching is unsuccessful, no answer-back signal will be output. Readjust using two-point teaching.
(Teaching will be unsuccessful if there is no difference in incident between the mark and base.)
4. If the answer-back signal is ON, the whole teaching operation will be completed. The output will be turned ON whenever the mark
(i.e., the color with shorter passing time) is detected.
Note: Make sure that the input tolerance of each pulse is within ±0.1 s.

Precautions when Using Automatic Teaching
Incorrect discrimination may be caused by automatic teaching in
the following cases. Use one-point or two-point teaching in such
cases.
Color patterns exist in the base.
Sensing objects change their positions.
Sensing objects have protrusions or surface level differences.
Threshold Level Adjustments
It is possible to make fine adjustments of the threshold level after
teaching. Such fine adjustments can be made remotely as well.
Refer to Remote Control Function.
1Set the mode selector to ADJUST.
2Select the upper or lower threshold setting with the thresh-
old selector. Whenever the SET button is pressed, the
threshold level will move. Two indicators will be lit together
when the threshold level is an even level.
The threshold level increases.
The threshold level decreases.

Detection Level Indicator
The control output of the E3M-V will be turned ON if the detection
level exceeds the threshold level. The indication of the detection
level varies with the teaching method.
One-point Teaching
The upper and lower threshold values are set on the basis of the
mark and the detection level indicators indicate the degree of
color conformity to the mark’s color.

Precautions
JSAFETY
Observe the following precautions to ensure safety.
Do not use the Sensor in locations subject to flammable or
explosive gases.
Do not use the Sensor in water or conductive solution.
Do not disassemble, repair, or modify the Sensor.
Use the Sensor under proper power supply specifications
such as the use of AC or DC power supply.
Do not apply any voltage or current exceeding the rated level.
Be careful with the power supply polarities and wire correctly.
Connect the loads correctly.
Do not short-circuit both ends of loads.
JINSTALLATION AND USE
Power Reset Time
Since the E3M-V is ready to detect objects from 100 ms max.
after the E3M-V is turned ON, operate the remaining devices
100 ms after the Sensor is turned ON. If power is supplied to the
E3M-V and the load independently, be sure to turn on the E3M-V
first.
Power OFF
The E3M-V may output a single pulse when the control power
supply is turned OFF. If the E3M-V is connected to a timer or
counter to which power is supplied from an independent power
supply, the E3M-V will be more likely to output a single pulse
when the control power supply is turned OFF. For this reason,
supply power to the timer or counter from the same power supply
for the E3M-V.
Power Supply Type
Supply voltage ripple must not exceed rated percentage.
Power Supply Connection
Be sure to ground the FG (frame ground) and G (ground)
terminals if a switching regulator is connected to the E3M-V to
avoid malfunction due to the switching noise of the switching
regulator.
JWIRING
Cable
The cable can be extended up to 100 m provided that the
thickness of the cable is 0.3 mm2minimum.
The cable must not be bent repeatedly.
Do not pull cables with pulling forces exceeding 50N
(11.24 lb).
High-tension Lines
To avoid damage and malfunctioning due to induction noise, wire
sensor power lines in a separate conduit from any power lines or
high tension lines.
JMOUNTING
Screw Tightening
Make sure that the casing is tightened to a maximum torque of
1.2 N Sm.
Mounting Direction
When Sensors are mounted to face each other, make sure to
adjust the optical axes to avoid mutual interference.
JEEPROM WRITE ERROR
An EEPROM error may result if power supply to the Sensor fails
or the Sensor is influenced by static noise, and the threshold
level indicators will flash. Perform the teaching and threshold
level setting of the E3M-V again.
JM12 METAL CONNECTOR
Turn off the E3M-V before connecting or disconnecting the
metal connector.
Make sure to hold the connector cover when connecting or
disconnecting the metal connector.
Tighten the metal connector securely by hand. To avoid dam-
age, do not use any tool, such as pliers.
If the metal connector is not tightened securely, it may be
disconnected by vibration, and the proper degree of protec-
tion of the E3M-V may not be maintained.
