Frequently Asked Questions - E3X-DAC-S OMRON

How to store a color with the E3X-DAC-S?

Place the SET/RUN selector to SET position, then use the MODE key to start teaching. Two methods are possible: 1-point teaching (long press MODE in RUN) or with/without workpiece teaching (recommended for margins). Follow the OVER/OK/LO indications on the secondary display.

What is the maximum detection distance?

The distance depends on the fiber head used. For example, with the E32-CC200 fiber in high-resolution mode, the distance is 60 mm on white paper. Refer to the distance tables in the manual for different fiber models.

How to switch between detection modes (C, I, Black)?

In SET mode, navigate to the parameter 'Judgment mode'. You can choose: C mode (RGB ratio), I mode (intensity of one color), Black mode (total RGB intensity) or Auto (automatic selection).

What to do if the sensor does not detect colors correctly?

First check the distance and installation angle (tilt 5 to 20° for shiny surfaces). Perform a with/without workpiece teaching to set the optimal threshold. Ensure the fiber head is clean and the white LED is working.

How to connect multiple amplifiers together?

Use the OMRON simplified connectors. The first amplifier receives a master connector (E3X-CN11) and the following ones receive slave connectors (E3X-CN12). Up to 16 units can be mounted on the same DIN rail. Power is supplied via the connector.

What are the available response times?

Four modes are available: super high speed (60 µs), high speed (300 µs), standard (1 ms) and high resolution (4 ms). The super high speed mode only accepts mode I (intensity).

How to adjust the threshold manually?

In RUN mode, use the UP/DOWN keys to adjust the threshold displayed on the sub-screen. The default threshold value during 1-point teaching is about -10% of the matching level. You can also change the teaching level in SET.

What does the 'OVER/CUR' flashing on the display mean?

This indicates an overload or short circuit on the control output. Check the load wiring and current limit (50 mA max). Turn off power, correct the fault, then turn on again.

Can the sensor be used with retro-reflective fibers?

No, retro-reflective, limited reflection, ultra-compact or specific fibers are not compatible. Use only the fibers listed in the detection distance tables (E32 series).

How to clean and maintain the sensor?

Keep the protective cover always in place. Clean the lenses with a soft, dry cloth. Avoid solvents. Do not expose to splashes of water, oils or chemicals. Store in a dry, temperate environment.

USER MANUAL E3X-DAC-S OMRON

The Fiber Sensor That Sees in Color

Easy and Reliable ... Featuring a Color-sensing Engine

The color-sensing engine uses three parameters, RGB, to process incident light. It detects color information from the workpiece for precise detection of color differences.

Intensity Detection (Conventional Type)

Color Detection (Color Sensing Type)

Incident light intensity

RGB ratio

Precise Detection

Color VS. Detection Capability

A high-power white LED and a multi-RGB processing system combine to cover all RGB wavelengths, enabling easy and accurate detection of workpieces without having to use a different light source to match each one.

Changes in the three parameters are processed as a ratio, so they are not affected by light-intensity variations due to workpiece movement.

Thinnest in the Industry

A Slim, 10-mm-wide Amplifier Unit

Use of a white LED and a one-package RGB light-receiving element has made it possible to unify the Amplifier Unit, both in size and operation, with conventional models. If detection should become unstable, the Amplifier Unit can be separately replaced to immediately regain stability.

Easy and Reliable ... Ease of Use and Smart Functions

In addition to ensuring easy use, we have added a number of smart functions, such as remote control to simplify setup, and twin sensing and output to simultaneously distinguish two registered colors. (advanced models)

Reliable

Setting guide function.

First in Its Class

This function guides the user to ensure that the workpiece is in an appropriate position for teaching. (Indicates OVER, OK, or LOW.)

Easy and Reliable ... Simplified Wiring Connector Reduces Work Steps

OMRON's unique simplified wiring connectors provide the power for each added Sensor. Up to 16 Units can be mounted, including a combination of Digital Fiber Sensors and other simplified wiring connector products such as Digital Laser Sensors.

Power is supplied through the connector, so only one output wire is required. (For adding Sensors)

Proximity Sensor: E2C-EDA

Wide Range of Fiber Heads Available

Select from a wide range of Fiber Heads to match the workpiece and working space. This makes installation possible even in small spaces.

Easy and Reliable Applications (Examples)

Detecting Marks

Because it distinguishes RGB ratios, detection is highly resistant to workpiece movement.

Distinguishing Semi-transparent Objects

Through-beam Fiber Heads are capable of detecting color differences in semi-transparent objects.

Many Compact Heads

Detecting Black Marks

In Black Mode, black seam tape and other black marks can be detected regardless of film color or patterns.

Distinguishing Trays

Twin sensing and remote control functions simplify setup.

Detecting Wafers

Workpieces that absorb a specific wavelength can be detected with a wide range of wavelengths.

Detecting Products on Conveyors

If you teach the conveyor (i.e., the background), you can detect workpieces even if they have different colors, shapes, or gloss.

Designing

Operation after Turning Power ON

The Sensor is ready to detect within 200 ms after the power supply is turned ON. If the Sensor and load are connected to separate power supplies, be sure to turn ON the Sensor first. Time may be required for the incident level to stabilize after the power supply is turned ON.

Operation When Turning Power OFF

Output pulses may occur when the power is turned OFF. Turn OFF the power supply to the load and the load line before turning OFF the power supply to the Sensor.

Mounting

Connecting and Disconnecting Connectors

Mounting Connectors

1. Insert the Master or Slave Connector into the Amplifier Unit until it clicks into place.

1. Attach the protector seals (provided as accessories) to the sides of master and slave connectors that are not connected.

Note: Attach the seals to the sides with grooves.

Removing Connectors

1. Slide the slave Amplifier Unit(s) for which the Connector is to be removed away from the rest of the group.
2. After the Amplifier Unit(s) has been separated, press down on the lever on the Connector and remove it. (Do not attempt to remove Connectors without separating them from other Amplifier Units first.)

Adding and Removing Amplifier Units

Adding Amplifier Units

1. Mount the Amplifier Units one at a time onto the DIN track.

1. Slide the Amplifier Units together, line up the clips, and press the Amplifier Units together until they click into place.

Removing Amplifier Units

Slide Amplifier Units away from each other, and remove from the DIN track one at a time. (Do not attempt to remove Amplifier Units from the DIN track without separating them first.)

Note:1. The specifications for ambient temperature will vary according to the number of Amplifier Units used together. For details, refer to Ratings and Specifications.
2. Always turn OFF the power supply before joining or separating Amplifier Units.

Mounting the End Plate (PFP-M)

An End Plate should be used if there is a possibility of the Amplifier Unit moving, e.g., due to vibration.

Fiber Connection

The E3X Amplifier Unit has a lock button for easy connection of the Fiber Unit. Connect or disconnect the fibers using the following procedures:

1. Connection

Open the protective cover, insert the fibers according to the fiber insertion marks on the side of the Amplifier Unit, and lower the lock lever.

Note: Do not pull on, compress, or otherwise exert excessive force on the fibers after connecting them to the Amplifier Unit. (Do not exert more than 0.3 N·m.)

2. Disconnecting Fibers

Remove the protective cover and raise the lock lever to pull out the fibers.

Note:1. To maintain the fiber properties, confirm that the lock is released before removing the fibers.
2. Be sure to lock or unlock the lock button within an ambient temperature range between -10^ and 40^ .

Adjusting

Mutual Interference Protection Function

Light from other sensors can cause the value on the digital display to become somewhat unstable. If this occurs, reduce the threshold to create a greater margin and enable more stable detection.

Shorting the Output

If the output short-circuit function operates because the load connected to the control output is short-circuited, OVER/CUR will flash on the display. Check the connection of the load.

EEPROM Writing Error

If the data is not written to the EEPROM correctly due to a power failure or static-electric noise, initialize the settings with the keys on the Amplifier Unit. ERR/EEP will flash on the display when a writing error has occurred.

Optical Communications

Several Amplifier Units can be slid together and used in groups. Do not, however, slide the Amplifier Units or attempt to remove any of the Amplifier Units during operation.

Others

Protective Cover

Always keep the protective cover in place when using the Amplifier Unit.

Fiber Unit

Design Precautions

Applicable Fiber Units

Refer to the sensing distance tables on pages 8 to 10 for the Fiber Units that can be used and the sensing distances. Retro-reflective, Limited-reflective, Ultra-compact, and Application-specific Fiber Units, which are not listed, cannot be used.

- Installation Precautions

Glossy Sensing Objects

If the sensing object is glossy, detection may not be stable. If the Sensor is inclined by 5^ to 20^ when using a glossy sensing object, as shown below, detection capabilities can be increased and stable detection achieved.

The operation mode is set with the Mode Selector.

Operation mode		Operation
Match ON	L-ON	L (Factory-set)
Mismatch ON	D-ON	D

• Advanced Models

The operation mode is set in SET mode.

Page 20 Refer to 4. Setting Functions in SET Mode.

• Advanced Models

Set the Channel Selector to the desired channel before making any adjustments or settings. This is true for all adjustments and settings.

2 Registering Workpiece Colors with Teaching in SET Mode

工 *Workpiece colors must always be taught to perform judgment for registered workpiece colors.

• With the factory settings, 1-point teaching can be executed in RUN mode. (Press the MODE Key for 3 s.)

2-1. One-point Teaching

Along with registering the workpiece colors, the threshold can be set at approximately -10% of the match.

The setting is completed in a simple operation with one press of a button.

• The threshold level can be changed if the teaching level function is used in SET mode.
• If BLACK mode is selected as the judgment mode in SET mode, the threshold will be set to a level of approximately 10% higher than the displayed degree of matching.

2-2. Teaching with and without the Workpiece

Two points, with and without the workpiece, are detected, and the match of the intermediate point is set as the threshold value.

This method is ideal for setting thresholds with margins or performing judgments with low match.

• When teaching is performed, position the workpiece by using the OVER, OK, and LO messages displayed on the sub-display (green) as guides.

OVER:Move the workpiece away.

OK : Teaching is possible.

LO :Move the workpiece closer.

3 Setting Thresholds Manually in RUN Mode

A threshold can be set manually. A threshold value can also be fine-tuned using manual setting after teaching.

• Even if the display method for the Display Switch Function is changed, the threshold will appear on the sub-display when the key is pressed.
