**E3Z-LS** 

## **Safety Precautions** 

## **Refer to** _**Safety Precautions**_ **of the E3Z and** _**Warranty and Limitations of Liability**_ **.** 

## **WARNING** 

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

## **Caution** 

**Do not connect an AC power supply to the Sensor. If AC power (100 VAC or more) is supplied to the Sensor, it may explode or burn.** 

## **Precautions for Safe Use** 

Be sure to abide by the following precautions for the safe operation of the Sensor. 

## ● **Wiring** 

## **Power Supply Voltage and Output Load Power Supply** 

## **Voltage** 

Make sure that the power supply to the Sensor is within the rated voltage range. If a voltage exceeding the rated voltage range is supplied to the Sensor, it may explode or burn. 

## **Load Short-circuiting** 

Do not short-circuit the load, otherwise the Sensor may be damaged. 

## **Connection without Load** 

Do not connect the power supply to the Sensor with no load connected, otherwise the internal elements may explode or burn. 

## ● **Operating Environment** 

Do not use the Sensor in locations with explosive or flammable gas. 

## **Precautions for Correct Use** 

Do not use the product in atmospheres or environments that exceed product ratings. 

## ● **Designing** 

## **Power Reset Time** 

The Sensor is ready to operate 100 ms after the Sensor is turned ON. If the load and Sensor are connected to independent power supplies respectively, be sure to turn ON the Sensor before supplying power to the load. 

## ● **Wiring** 

## **Avoiding Malfunctions** 

If using the Sensor with an inverter or servomotor, always ground the FG (frame ground) and G (ground) terminals, otherwise the Sensor may malfunction. 

## ● **Mounting** 

## **Mounting the Sensor** 

- If Sensors are mounted face-to-face, make sure that the optical axes are not in opposition to each other. Otherwise, mutual interference may result. 

- Always install the Sensor carefully so that the aperture angle range of the Sensor will not cause it to be directly exposed to intensive light, such as sunlight, fluorescent light, or incandescent light. 

- Do not strike the Photoelectric Sensor with a hammer or any other tool during the installation of the Sensor, or the Sensor will lose its water-resistive properties. 

- Use M3 screws to mount the Sensor. 

- When mounting the case, make sure that the tightening torque applied to each screw does not exceed 0.54 N·m. 

## **M8 Connector** 

- Always turn OFF the power supply to the Sensor before connecting or disconnecting the metal connector. 

- Hold the connector cover to connect or disconnect it. 

- If the XS3F is used, always tighten the connector cover by hand. Do not use pliers. 

- If the connector is not connected securely, it may be disconnected by vibration or the proper degree of protection of the Sensor may not be maintained. The appropriate tightening torque is 0.3 to 0.4 N·m. 

If other commercially available connectors are used, follow the recommended connector application conditions and recommended tightening torque specifications. 

## **Mounting Directions** 

- Make sure that the sensing side of the Sensor is parallel with the surface of the sensing objects. Normally, do not incline the Sensor towards the sensing Sensing side object. Surface of sensing object 

**==> picture [70 x 52] intentionally omitted <==**

If the sensing object has a glossy surface, however, incline the Sensor by 5 ° to 10 ° as shown in the illustration, provided that the Sensor is not influenced by background objects. 

- If there is a mirror-like object below the Sensor, the Sensor may not Glossy object operate stably. Therefore, incline 

the Sensor or separate the Sensor from the mirror-like object as shown below.

- Note: 1. If the stability indicator is lit, the detection/no detection status is stable within the rated ambient operating temperature ( − 25 to 55 ° C). 

   2. The VERY FAR region is supported only for FGS. The incident light threshold is fixed and cannot be set. The distance to the incident light threshold depends on the color and gloss of the sensing object's surface.
