The following settings are possible in RUN or ADJ mode. (Each pin of the function switch is factory-set to the upper position.)
(6 ms) C 3 ms
Note: Figures shown in parentheses are for the 4-output models.
1 ms TMR (2 ms) 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
Sensor
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.
E3MC-X E3MC-(M)Y (reflective optical fiber)
Object to be detected
0 to 20
Sensing target
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
E3MC-A
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.
Object to be detected
Note: To avoid malfunction, provide a cover to shut out direct external light interference to the E3MC.
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.
E3MC
OK: All Detection Level Indicators (green) illuminated. Bring the fiber head as close as possible to the workpiece and conduct teaching. NG: All Threshold Indicators (red) flashing.
Feed workpieces and check if they are detected.
Excessive light. Move the head away from the workpiece and find a position where teaching is accepted. This position is the optimum distance.
REGISTERED COLOR SELECTION (BANK SELECTION INPUT)
Single-Output Models ONLY (E3MC-A /E3MC-X /E3MC-Y )
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.

This status can be on hold by an external synchronous input. It will be released by setting the external synchronous input to OFF.
This status can be on hold so that unwanted 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. IP 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 1/2" 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 cm 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). nm 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. *
E3MC
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.
WIRING
Cable
* * * The cable can be extended up to 100 m, allowing for a cable thickness of 0.3 mm2 maximum. The cable must not be repeatedly bent. Do not pull cables with pulling forces exceeding 50 N (11.24 lb force). 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. Never run the E3MC Color Sensor cables in the same conduit with power lines or high tension cables.
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. 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 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, eliminating the switching noise of the regulator to avoid a malfunction.

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.
