16 E3G Precautions Do not ignore the following items that are essential for securing safety during Sensor operation. Do not use the Sensor in locations with explosive or flammable gas. Do not use the Sensor in the water or electrically conductive solutions. Do not disassemble, repair, or modify the product. E3G Make sure that the power supply specifications, such as AC or DC, are correct. Do not apply voltage or current exceeding the rated ranges. Do not make mistakes in wiring, such as mistakes in polarity. Be sure to connect the load correctly. Do not short-circuit the load terminals. J DESIGNING Load Relay Contact If E3G is connected to an inductive load with contacts that spark when the load is turned (e.g., a contactor or valve), the normally-closed side may be turned before the normally-open side is turned or vice-versa. If both normally-open output and normally-closed output are used simultaneously, apply an surge suppressor to the load. Stabilization on Power-up The Sensor needs 1 ms to be ready to operate after it is turned. The devices connected to E3G wait until the Sensor is ready to operate. If the Sensor and load are connected to separate power supplies, be sure to turn the Sensor first. Power A single pulse signal may be output from the Sensor immediately after it is turned. This will occur more frequently if a timer or counter is connected to the Sensor and power is supplied to the timer or counter independently. Be sure to supply power to the timer or counter from the built-in power supply of the Sensor. 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. Repeated Cable Bending Do not bend the sensor cable repeatedly. 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. J WIRING The E3G has a built-in function to protect the Sensor from load short-circuiting. If load short-circuiting results, the output will be turned. In that case, check the wiring and turn the E3G again so that the short-circuit protection circuit will be reset. This function will operate if the output current flow is at least 2. times the rated load current. If an inductive load is connected to the E3G, make sure that the inrush current does not exceed 1.2 times the rated load current. The cable can be extended up to a total length of 1 m, on condition that the thickness of the wire is at least.3 mm. J MOUNTING Mounting Conditions 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 M4 screws to mount the Sensor. When mounting the case, make sure that the tightening torque applied to each screw does not exceed 1.2 N S m. M12 Connector Be sure to connect or disconnect the M12 connector after turning the Sensor. Be sure to hold the connector cover when connecting or disconnecting the M12 connector. The M12 connector must be only hand-tightened. If the M12 connector is not connected securely, the proper degree of protection of the Sensor may not be maintained or the connector may be disconnected due to vibration. Water Resistance Do not use the product in water, in rain, or outdoors. Tighten the operation cover screws and terminal block cover screws to a torque of.3 to.5 N S m in order to ensure water resistivity. J MAINTENANCE AND INSPECTI Cleaning Use only water and mild detergent. Do not use harsh chemicals or solvents. J OPERATING ENVIRMENT Do not install the E3G in locations with the following conditions. Excessive dust. Corrosive gases. Directly exposed to sprays of water, oil, or chemicals. Directly exposed to vibration or shock. 17

33 E3G-L1/L3 Precautions J DESIGNING High-voltage Lines Do not place sensor power supply or signal lines within the same conduit as high-voltage power lines. Voltage Ratings Do not exceed rated supply voltage, ripple percent (for DC models), or load current limits. Ambient Lighting Do not install the sensor in direct sunlight or other sources of strong ambient light. Environmental Conditions Do not install the sensor in areas $ With high humidity, or where condensation would result $ With corrosive gas. $ With high vibration or shock. Power Supply If a switching power supply is used, or when using an inverter or servomotor, you must ground the FG (frame ground) and G (ground) terminals on the power supply for proper operation and to avoid damaging the sensor. Water Exposure Although conforming to IP67, do not use the sensor where it may be immsersed, is outdoors, or is exposed to rain. To ensure the water resistance of the sensor, tighten the screws of the operation panel cover to a torque of.2 to.3 N S m. Cable $ The bending radius of the cable should be at least 25 mm. $ When using extended power and signal cable, total length must not exceed 1 m, with a minimum wire size of.3 mm 2 (22 AWG). $ Do not apply tensile force exceeding 5 N to cable (preleaded and connector models). 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. Proper Mounting Screws Use M3 screws and washers to mount the sensor and bracket. Mechanical Shock Avoid mechanical shock during installation which may amage the housing (see Shock specifications) E3G-L1/L3 Short -circuit Protection If the load short -circuits, the output will be turned off. Disconnect power and check the wiring. After correcting the shorted condition, turn power back on. The sensor will reset the short-circuit protection function. The short-circuit protection is activated when the current flow is at least 2.4 times the rated load current. When using an inductive load, the inrush current must not exceed this factor. Connector $ When connecting or disconnecting the connector, hold the connector cover to avoid tension on the housoing. $ Tighten the connector by hand only. Do not use tools which may damage the connector. $ Always disconnect power before connecting or disconnecting the connector. $ Be sure that the connector is tightened securely. The sesnor enclosure rating may be reduced or the connector may get loosened. J MAINTENANCE AND INSPECTI Cleaning $ Solvents damage the casing of the sensor. Do not use solvents to clean the sensor. EEPROM Writing Error $ If a teaching data error occurs with the operation indicator flashing due to a power failure or static noise, perform the teaching operation of the sensor again. 17
