when the output of each channel
is ON.

Color Discrimination Mode Selection (Mode C is Recommended for Normal Applications)

Mode C: Color discrimination is performed according to R (red), G (green), and B (blue) ratio of the reflection light even

if the sensing objects fluctuate up and down within the rated sensing range.

Mode I: Color discrimination is performed according to RGB light intensity of reflection light. This mode ensures more

delicate color discrimination than mode C.

Response Time Selection

3 ms (6 ms): The E3MC can stably detect minute differences of color. Set the response time to 3 ms for usual

applications.

1 ms (2 ms): The E3MC will be in quick-response operation. Set the response time to 1 ms if high-speed response is

required.

OFF-delay Timer Setting

---:

No OFF-delay timer is set.

TMR: A 40-ms OFF-delay timer is set for control output.

Conformity/Non-conformity Output (See glossary--Light/Dark Operate)

Output is ON when the detected color coincides with the registered color.

Output is ON when the detected color does not coincide with the registered color.

Detection Level and Tolerance

As the detected color becomes closer to the registered
color, the number of illuminated detection level indicators
increases. When the E3MC is in conforming output mode,
the control output of the E3MC will be ON if the detection
level exceeds the threshold level and OFF if the detection
level does not exceed the threshold level.

Set the threshold to a higher level for highly-precise color
discrimination and to a lower level to ignore minor tint
differences or dirt retention.

TECHNICAL GUIDE

If the E3MC does not detect metal or glossy objects accurately, change the mounting angle of the E3MC so that it will not receive regular
reflection light directly reflected from the objects.

The mounting angle of the E3MC-X

can be adjusted to approximately 10

with the mounting holes.

Object to be detected

E3MC-X

E3MC-A

Note: To avoid malfunction, provide a cover to shut out direct

external light interference to the E3MC.

Sensing target

E3MC-(M)Y

(reflective optical fiber)

0 to 20

On the other hand, sensing targets such as metal or transparent
plastic cases may be detected by allowing regular reflection.

Detection of White, Gray, or Black Objects

When registering white, gray, or black objects, change the color
discrimination mode to "Mode I" to achieve a more stable color
discrimination.

External Light

The E3MC may malfunction if it directly receives external light
interference. Provide a cover to shut-out such external light
interference.

E3MC

Adjustment of Sensing Distance of General-purpose
Fiber-optic Type

Unlike the E3MC-A or E3MC-X, the E3MC-Y may require
adjustment of its sensing distance depending on the reflection
rate. This also applies to the through-beam type.

Bring the fiber head as
close as possible to the workpiece
and conduct teaching.

Feed workpieces and
check if they are detected.

Excessive light. Move the
head away from the work-
piece and find a position
where teaching is accepted.
This position is the optimum
distance.

OK: All Detection Level
Indicators (green) illuminated.

NG: All Threshold
Indicators (red)

)

The E3MC in RUN mode offers bank selection with external inputs by combining bank selection input 1 (yellow) and input 2 (green). The
selected bank is active when the indicator is illuminated.

EXTERNAL SYNCHRONOUS INPUT FUNCTION (See Note.)

The measurement results will be directly output to the control output if the input from the external synchronous input terminal (pink) is set
to OFF. The output will hold the previous status if the input of the external synchronous input terminal is set to ON. External synchronous
input is valid in RUN or ADJ mode.

color objects can be
ignored while they are
passing the sensing
range.

Note: External Synchronous Input: Latches sensor output in existing state when ESI is on. For example, if sensor output is on when ESI

is on, the output(s) will remain on until ESI is turned off, regardless of target presence or absence.
For NPN models, ESI is turned on by connections to 0V.
For PNP models, ESI is turned on by connections to +V.

Terms

Color Registration

Detection of a special mark on packaging material referred to
as the Registration Mark. This mark is aligned with the
printed pattern on the wrapping material and allows proper
cut-off of the packaging material so that printed images
appear in the correct location on the package.

Conformity/Non-conformity

In the E3MC Color Sensor, term used to indicate when the
target color matches a reference color stored in the memory
bank(s). A match is "conformity," and a mismatch is
"non-conformity."

D.O.

See Dark Operate.

Dark Operate

Operating mode where the output is turned on (transistor
becomes conducting, or relay coil is energized) when light is
NOT received. In the E3MC Color Sensor, this refers to the
mode where the output turns on when the target color does
NOT match (non-conformity) the reference color stored in the
memory bank.

Diffuse Reflective

Sensor configuration with the emitter and receiver located in
the same housing. Sensing of target is based on reflection of
light from the target itself (rather than a retroreflector).

Excess Gain

See Stability Indicator.

External Synchronous Input

In the E3MC Color Sensor, an input that allows "latching" of
the output when the input is taken high, preventing a change
of state until the input is taken low.

IEC

International Electrotechnical Commission.

Interference Protection

See Mutual Interference Protection.

International Protection; an international standard scale for
enclosure ratings (sealing).

IP66

Approximately NEMA 4, 4X, "heavy seas" test; the item is
subjected to a stream of water from a

" nozzle with 14psi

pressure at a distance of 1.5 meter. Water must not enter the
item.

IP67

Approximately NEMA 6, "immersion" test; the item is
immersed under 1 meter of water for 30 minutes, with no
water entry.

kgf

Kilogram Force.

kgf

Kilogram-force centimeters, measure of torque;
1 kgf

cm = 10.4 in

lb.

Lensed effect

Optical phenomenon where light passing through a
transparent object (bottle, for instance) is focused in the
same manner as a lens. If the lens effect is "converging," the
light intensity may be increased significantly. When sensing
the presence of an object due to the attenuation of light
passing through that object, the lens effect may cause a
failure to detect the object. The light intensity may not be
reduced due to the "lens" effect of concentrating the light
beam.

L.O.

See Light Operate.

Light Operate

Operating mode where the output is turned on (transistor
conducts, or relay coil is energized) when light is received. In
the E3MC Color Sensor, refers to the mode where the output
turns on when the target color matches (conforms) to the
reference color stored in the memory bank.

Mutual Inference Protection

Circuitry that allows the sensor to detect and compensate for
interfering signals that may be emanating from sources within
its sensing range. Sensor can then operate normally, ignoring
the interfering signal(s).

Nanometer; a measure of length, 10

--9

meters, 3.937 x 10

--8

inches.

NEMA

National Electrical Manufacturer's Association; industrial
trade organization that publishes testing standards, including
enclosure ratings.

NPN

Transistor output designed to provide a path to ground for
current passing through the load ("sinking"). When the NPN
output is on, current can then pass from Positive, through the
load, and through the NPN transistor to ground, completing
the circuit.

PNP

Transistor output that provides a path to "Plus" for current
passing through the load ("sourcing"). When the PNP output
is on, current can then pass from Positive, through the PNP
transistor, through the load, and to ground, completing the
circuit.

Reflective Mode

See Diffuse Reflective.

Response time

Elapsed time from when a target moves into the sensing
zone of a sensor to when the output turns on. May also refer
to the "turn-off" time. The sum of turn-on and turn-off time is
the total cycle time (reciprocal of switching frequency, Hz).

Reverse Polarity Protection

Circuitry that prevents damage to the device if power is
incorrectly connected (polarity reversed, DC). The unit may
not work while polarity is reversed, but is undamaged, and
will work once polarity is corrected.

E3MC

RGB

Red, green, blue, refers to the triple light source in the E3MC
Color Sensor. By sensing the reflection level of each color,
the sensor can determine the exact color of the target.

Short Circuit Protection

Circuitry that prevents damage to a device's output if the
output is short-circuited. Usually current is monitored, and the
output is turned off if current exceeds a predetermined value.

Stability Indicator

Indicator light that shows when a signal being received (such
as a light beam) is strong enough for stable operation.
Usually this stable operation is expressed as a percentage
above the switching threshold of the device.

Teach Function

Circuitry in a sensor that allows sensor threshold to be set
with the use of a "teach" input. Switching threshold is set
when the teach input is actuated, and it is based on signal
received at the moment of teaching.

Through-beam

Sensor where the emitter and receiver are in separate
housings, and arranged facing each other. The target would
be detected passing between the emitter and receiver,
interrupting the beam.

Precautions

AVOID DAMAGE TO THE E3MC

Voltage must not exceed the rated voltage of the E3MC.

When supplying power to the E3MC, make sure that the
polarity of the power is correct.

Do not short-circuit the load connected to the E3MC.

INSTALLATION

Power Up Ready

The E3MC is ready to sense objects 100 ms after the unit is
turned ON.

The 100 ms wait is also required when the E3MC output is
controlling other devices.

If power is supplied to the E3MC and the load independently,
be sure to turn ON the E3MC

first.

When the E3MC is turned ON or OFF, the operation indicator
will be illuminated for an instant, but no control output will be
turned ON.

Power Off

The E3MC may output a single pulse when the control power
supply is turned OFF. If the E3MC is connected to a timer or
counter, you should supply power to the timer or counter from
the same power supply as the E3MC.

Power Supplies

Power supply must be filtered with 10% MAX ripple (see
supply voltage specification).

When a switching regulator is required, you must connect the
FG (frame ground) and G (ground) terminals together, eliminat-
ing the switching noise of the regulator to avoid a malfunction.

WIRING

Cable

The cable can be extended up to 100 m, allowing for a cable
thickness of 0.3 mm

maximum.

The cable must not be repeatedly bent.

Do not pull cables with pulling forces exceeding 50 N
(11.24 lb

force).

M12 Metal Connector

When connecting or disconnecting the cable, first remove the
power to the E3MC.

To avoid damage, tighten the metal connector securely by
hand. Do

not use any tools.

To ensure that the enclosure rating is maintained (so that
water/vibration ratings are assured), the cable connector
must be

securely hand-tightened.

Avoid Damage or Malfunction Due to Induction Noise

Never run the E3MC Color Sensor cables in the same con-
duit with power lines or high tension cables.

FURTHER INFORMATION

Correcting an EEPROM Error

An EEPROM error may result if the power supplied to the
Sensor fails, or if the Sensor is influenced by static noise.
When an EEPROM error occurs, the operation and bank
indicators will flash and the buzzer will beep. The remedy is
to reprogram and make threshold level settings again.
