1. Attach the distance adjustment scale as shown in the figure and set it where the * mark is equal to the sensing distance. 

2. Turn the distance adjuster until the red spot is at point A (center of the distance adjustment scale). 

3. Remove the distance adjustment scale once the distance has been adjusted. Put a sensing object in place, and then adjust the sensitivity. 

## ● **Adjusting the E3S-LS20XE4 Convergent-reflective Sensor**

1. Set the sensitivity adjuster to the center as shown in the figure. 

2. Turn the distance adjuster counterclockwise until it is fully turned (L to S). 

3. Position the sensing object. 

4. Slowly turn the distance adjuster clockwise (S to L). 

5. Eventually the LIGHT (red) indicator will light. Turning the adjuster further will light the STABILITY (green) indicator. Leave the distance adjuster at this level. 

6. Adjust the sensitivity in this state.

## **Safety Precautions** 

## **Be sure to read the precautions for all models in the website at: http://www.ia.omron.com/. Warning Indications** 

## **Precautions for Correct Use** 

**Warning level** Indicates a potentially hazardous situation which, **WARNING** if not avoided, will result in minor or moderate injury, or may result in serious injury or death. Additionally there may be significant property damage. **Precautions** Supplementary comments on what to do or avoid **for Safe Use** doing, to use the product safely. **Precautions** Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction or **for Correct Use** undesirable effect on product performance. 

- 1.Do not use the product in any atmosphere or environment that exceeds the ratings. 

- 2.Use M4 screws to mount the sensor and tighten each screw to a maximum torque of 1.2 N-m. 

- 3.Do not apply the forces on the cable exceeding the following limits: - 

- Pull: 40 N; torque: 0.1 N m; pressure: 20 N; bending: 29.4 N 

- 4.Make sure to tighten the connectors. 

- 5.It may take time until the incident level and measurement value become stable immediately after the power is turned on depending on use environment. 

## **Meaning of Product Safety Symbols** 

**==> picture [32 x 32] intentionally omitted <==**

**General prohibition** Indicates the instructions of unspecified prohibited action. 

- 6.Burn injury may occur. The product surface temperature rises depending on application conditions, such as the ambient temperature and the power supply voltage. Attention must be paid during operation or cleaning. 

## **WARNING** 

If the sensing object has a metallic or shiny surface, the E3SR may not detect it properly. To avoid this situation, place the sensing object so that it is not at right angles to the Photoelectric Sensor. 

**This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes.**

## **Precautions for Safe Use** 

The following precautions must be observed to ensure safe operation. 

- 1.Doing so may cause damage or fire. Do not install the product in the following locations. 

- Locations subject to direct sunlight 

   - **Attaching the E39-S Slit** 

- Locations subject to condensation due to high humidity 

   - The Slit can be fitted vertically or horizontally as indicated by the dotted line. Make sure that Slits for the Emitter and the Receiver are fitted in the same orientation. 

- Locations subject to corrosive gas 

- Locations subject to vibration or mechanical shocks exceeding the rated values 

   - Place the packing in the supporter and hook the claws on the indentations in the Sensor head. 

- Locations subject to steam 

- Locations subject to strong magnetic field or electric field 

- 2.Do not use the product in environments subject to flammable or explosive gases. 

   - If the supporter is contacting the mounting surface, insert a spacer to separate it. (Refer to _Slit Dimensions_ .) 

   - An operating position accuracy of 0.1 mm max. can be achieved for a Through-beam Sensor without Slits. 

- 3.Do not use a voltage in excess of the operating voltage range. Applying a voltage in excess of the operating voltage range, or applying AC power to a DC Sensor may cause explosion or burning.

- 4.Doing so may cause damage, fire, explosion or malfunction. 

- Never use the product with damaged body or cable. 

- Never disassemble, repair nor tamper with the product. 

- Never use the product with incorrect power supply or wiring. 

- 5.Do not short the load. Otherwise explosion or burning may result. 

- 6.Do not use the Sensor in environments where the cables may become immersed in oil or other liquids or where liquids may penetrate the Sensor. Doing so may result in damage from burning and fire, particularly if the liquid is flammable.

Z: Zener diode (Vz = 30 V) 

- The operation mode depends on the wiring of the brown and blue lines. 

Note 1. Only C42 models with die-cast cases are available. 

2. The Emitter for a Through-beam C4-type Sensor is the same as the Emitter for an E4-type Sensor. (E.g., E3S-5LE4) 

3. When a C- or B- type Sensor experiences a load short-circuit or overload, the output transistor will be turned OFF. Check the load conditions before turning the power back ON.

Note: Models numbers for Through-beam Sensors (E3S- @ E4, E3S- @ E41) are for sets that include both the Emitter and Receiver. 

The model number of the Emitter is expressed by adding "L" to the set model number (example: E3S-2LE4), the model number of the Receiver, by adding "D" (example: E3S-2DE4.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

Any advice, recommendations or information given orally or in writing, are not to be construed as an amendment or addition to the above warranty. 

See http://www.omron.com/global/ or contact your Omron representative for published information. 

## Limitation on Liability; Etc. 

OMRON COMPANIES SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY. Further, in no event shall liability of Omron Companies exceed the individual price of the Product on which liability is asserted. 

## Suitability of Use. 

Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

## Programmable Products. 

Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof. 

## Performance Data. 

Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability. 

## Change in Specifications. 

Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product. 

## Errors and Omissions. 

Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical or proofreading errors or omissions. 

**In the interest of product improvement, specifications are subject to change without notice.**
