SET button For teaching or for threshold adjustment Installation Designing Mounting Do not pull cables with tensile strength exceeding 50 N for the cable pull-out or connector types. Mounting Conditions High-tension Lines Do not wire power lines or high-tension lines alongside the lines of the Sensor in the same conduit, otherwise the Sensor may be damaged or may malfunction due to induction. Be sure to wire the lines of the Sensor separated from power lines or high-tension lines or laid in an exclusive, shielded conduit. Turning the Power ON The Sensor needs 100 ms to be ready to operate after it is turned ON. The devices connected to the Photoelectric Sensor must wait until the Sensor is ready to operate. If the Sensor and load are connected to separate power supplies, be sure to turn ON the Sensor first. Power Supply If a standard switching regulator is used, be sure to ground the FG (frame ground) and G (ground) terminals, otherwise the Sensor may malfunction due to the switching noise of the regulator. Wiring Cable * The bending radius of the cable should be 25 mm min. * In a case where the cable is extended, use a wire with 0.3 mm2 min. The total length of the cable should be 100 m max. * If Sensors are mounted face-to-face, make sure that no optical axes cross each other. Otherwise, mutual interference may result. * Be sure to install the Sensor carefully so that the directional angle range of the Sensor will not 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 loose 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 Nxm. M8 Connector * Be sure to connect or disconnect the M8 connector after turning OFF the Sensor. * Be sure to hold the connector cover when connecting or disconnecting the M8 connector. * Secure the M8 connector by hand. Do not use any pliers, otherwise the connector may be damaged. * If the M8 connector is not connected securely, the M8 connector may be disconnected by vibration or the proper degree of protection of the Sensor may not be maintained. Avoiding Malfunctions If using the photoelectric sensor with an inverter or servomotor, be sure to ground the FG (frame ground) and G (ground) terminals, otherwise the Sensor may malfunction. 7 E3G-L1/L3 E3G-L1/L3 Mounting Directions Make sure that the sensing side of the Sensor is parallel with the surface of each sensing object. Do not incline the Sensor towards the sensing object. Install the Sensor as shown in the following if each sensing object greatly differs in color or material. Correct Incorrect Sensing side Surface of sensing object If the sensing object has a glossy surface, incline the Sensor by 5 to 10 as shown below, provided that the Sensor is not influenced by any background objects. Moving direction Moving direction Adjustments If the Sensor is not in stable operation due to color differences, make a fine adjustment of the threshold level and confirm that the Sensor operates in stable state. Refer to Manual Teaching (Fine Distance Setting) Page 12 Glossy object If there is a mirror-like object below the Sensor, the Sensor may not be in stable operation. Therefore, incline the Sensor or keep the Sensor a distance away from the mirror-like object as shown below. Sensing object Mirror-like object Make sure not to install the Sensor in the incorrect direction. Refer to the following.
