• Avoid locations with strong electric or magnetic fields.
• Do not disassemble, repair, or modify the product.
• Do not apply voltage or current exceeding the rated values.
• Do not use in ambient conditions or environments exceeding the rated values.
• Ensure correct wiring, especially for power polarity.
• Do not use if the case is damaged.
• Dispose of as industrial waste.
• The sensor surface may become hot depending on operating conditions (ambient temperature, power voltage, etc.). Handle with care during operation or cleaning.
• Separate wiring for high-voltage lines, power lines, and the product's wiring.
• Ensure safety by stopping equipment before sensor setup.
• Avoid installation in direct sunlight, humid areas prone to condensation, areas with corrosive gases, or areas with vibrations or shocks exceeding rated values.

• Limit force applied to the cord: Tension below 40N, Torque below 0.1 N·m, Pressure below 20N, Bending below 3kg.
• Detection is possible after 200ms from power ON. If the load and the product are separate, ensure the product's power is turned on first.
• For connector type, attach protective caps (included with E3X-CN series connectors) to unused power terminals to prevent electric shock or short circuits.
• A power pulse may occur when power is cut off. Turn off the power to the load or load line first.
• Excessive sensor light may cause malfunction due to insufficient mutual interference prevention. In such cases, set a wider limit.
• Always turn off the power when attaching, detaching, or expanding amplifiers.
• Do not apply excessive force (pulling or compressing) to the fiber unit while it is fixed to the amplifier unit (below 9.8N).
• Mobile Console models E3X-MC11, E3X-MC11-SV2, E3X-MC11-S cannot be used.
• Mutual interference prevention does not function with models E3X-DA-N/SD/NA. It functions with models E3X-DA-S/MDA.
• Always use with the protective cover attached.
• Communication unit models E3X-DRT21-S, E3X-CRT, E3X-ECT cannot be used.
• Do not use thinner, benzene, acetone, kerosene, etc., for cleaning.

1-3 Fiber Unit Installation

Using the Fiber Cutter (Model E39-F4):

1. Insert the fiber unit into the fiber cutter hole. For standard fiber units, insert to the desired cutting position. For fine fiber units, insert fully.
2. Press down firmly on the blade to cut.

Installing the Fiber Unit:

1. Open the protective cover.
2. Raise the lock lever.
3. Insert the fiber unit fully into the amplifier unit's insertion port.
4. Turn the lock lever back to its original position to secure the fiber unit.

CHECK!

• When attaching a coaxial reflective fiber unit to the main unit, attach the single-core fiber unit to the upper side (light emission) of the mounting hole and the multi-core fiber unit to the lower side (light reception).

2. Setup Guide

Diagram illustrating the various buttons and indicators on the amplifier unit:

• [L/D Indicator]: Displays Light ON/Dark ON setting status.
• [OUT Indicator]: Lights up when the output is ON.
• [ST Indicator]: Lights up during Smart Tuning.
• [TUNE] Button: Used for sensitivity adjustment.
• [UP/DOWN] Buttons: Adjust the limit value.
• [MODE] Button: Switches between setting mode and detection mode (press and hold for 3 seconds).
• [L/D] Button: Switches between Light ON and Dark ON (press and hold for 7 seconds to reset settings).
• [DPC Indicator]: Lights up when Dynamic Power Control is active.
• Digital Displays: Show light reception levels and limit values.

2-2 Control Output Switching Method

Use the [L/D] button to switch between Light ON and Dark ON modes.

• For Through-beam sensors: To turn ON when the object is present, set to "Dark ON". The [L/D Indicator] lights up.
• For Reflective sensors: To turn ON when the object is present, set to "Light ON". The [L/D Indicator] lights up.

2-3 Smart Tuning [Simple Sensitivity Adjustment]

Smart Tuning Error Messages:

The adjustment range for Smart Tuning is approximately 20 to 1/100. When selecting the "Giga Mode" detection function, the initial value is large, resulting in an adjustment range of approximately 2 to 1/100. Refer to "⑤ Detailed Setup" to change the Power Tuning level.

1. When detecting presence/absence of an object:

• 2-point Tuning: Press the [TUNE] button once with the object present and once without the object. The [ST Indicator] will light up.
• Power Tuning: Adjusts the maximum light reception to the Power Tuning level. Sets the limit value to the midpoint between maximum and minimum light reception.
• Position Tuning: Press the [TUNE] button with no object present. Then, place the object at the desired position and press and hold the button. The red digital display changes from [2Pnt] to [Po5]. Sets light reception to half of the light reception in step 1. Sets the limit value to the same value as the light reception in step 2.
• Full Auto Tuning: Press and hold the [TUNE] button with no object present until [IPnt]→[FULL]→[Auto] is displayed on the red digital display. Pass the object through the sensor (keep pressing the [TUNE] button while the object passes; release the button when [Auto] is displayed). This takes over 7 seconds. Sets light reception to half of the light reception in step 1. Sets the limit value to the midpoint between the light reception in step 1 and step 2.
• Percent Tuning: In setting mode, turn Percent Tuning ON. Press the [TUNE] button again with no object present. Sets light reception to the larger of the two light reception values (from steps 1 and 2). Sets the limit value to the midpoint between the light reception values of steps 1 and 2.
• Max Sensitivity Tuning: Press the [TUNE] button more than 3 times with the object present (through-beam) or absent (reflective) until [st FULL] is displayed, then release. Sets light reception to the light reception value in step 2. Sets the limit value to [Light reception value of step 2 * Percent Tuning level + Light reception value of step 2].

2. When you want to prevent dust or dirt:

• Percent Tuning: Set Percent Tuning ON in setting mode. Press the [TUNE] button again with no object present. Sets light reception to the larger of the two light reception values (from steps 1 and 2). Sets the limit value to the midpoint between the light reception values of steps 1 and 2.

3. When the object is moving without stopping the line:

• Full Auto Tuning: Press and hold the [TUNE] button with no object present until [IPnt]→[FULL]→[Auto] is displayed on the red digital display. Pass the object through the sensor (keep pressing the [TUNE] button while the object passes; release the button when [Auto] is displayed). This takes over 7 seconds. Sets light reception to half of the light reception in step 1. Sets the limit value to the midpoint between the light reception in step 1 and step 2.

4. When you want to determine the object's position:

• Position Tuning: Press the [TUNE] button with no object present. Then, place the object at the desired position and press and hold the button. The red digital display changes from [2Pnt] to [Po5]. Sets light reception to half of the light reception in step 1. Sets the limit value to the same value as the light reception in step 2.

5. When you want to detect transparent objects and small objects (set limit value by light reception ratio):

• Percent Tuning: In setting mode, turn Percent Tuning ON. Press the [TUNE] button again with no object present. Sets light reception to the larger of the two light reception values (from steps 1 and 2). Sets the limit value to the midpoint between the light reception values of steps 1 and 2.

2-4 Fine Limit Adjustment

Use the [UP/DOWN] buttons to adjust the limit value. Pressing and holding the buttons allows for high-speed adjustment.

• For single-core fiber: Sets light reception to "0" for the light reception value in step 1. Sets the limit value to approximately 7% of the light reception value in step 1. This is set to the minimum value for the output to turn ON correctly when the light reception value in step 1 is small, such as in long-distance detection.
• For multi-core fiber: Sets light reception to "0" for the light reception value in step 1. Sets the limit value to approximately 7% of the light reception value in step 1.

CHECK!

• If Percent Tuning is set, Smart Tuning other than Power Tuning cannot be executed.
