e3g e3g 17 precautions do not ignore the following items that are e ssential for securing safety during sensor operation. ? do not use the sensor in locations with e xplosive or flam- mable gas. ? do not use the sensor in the water or electrically conductive solutions. ? do not disassemble, repair, or modify the p roduct. ? make sure that the power supply specifications, such a s 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 a n inductive load with contacts that spark when the load is turned off (e.g., a contactor o r valve), the normally-closed side may be turned on before the normally-open side is turned off o r vice-versa. if both normally-open output and normally-closed output are u sed simultaneously, apply a n surge suppressor to the load. stabilization on power-up the sensor needs 100 ms to be ready to operate a fter it is turned on. 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 on the sensor first. power off a single pulse signal may b e output from the sensor immediately after i t i s turned off. this will occur more fr equently if a timer or counter is connected to the sensor and power is supplied to the timer o r counter independently. be sure to supply power to the timer o r counter from the built-in power supply o f 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 b e 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 off. in that case, check the wiring and turn on the e3g again so that the short-circuit p rotection circuit will be reset. this function will operate if the output current flow is at least 2 .0 times the rated load current. if a n 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 o f 100 m, on condition that the thickness o f the wire is a t least 0 .3 mm. j mounting mounting conditions if sensors a re mounted face-to-face, make sure that no optical axes cross each o ther. otherwise, mutual interference may result. be sure to install the sensor carefully so that the d irectional angle range of the sensor will not be directly exposed to intensive light, such a s sunlight, fluorescent light, o r incandescent light. do not strike the photoelectric sensor with a hammer o r any other tool during the installation of the sensor, or the sensor will loose its water-resistive pr operties. 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 o r d isconnect the m12 connector a fter turning off the sensor. be sure to hold the connector cover when connecting or disconnecting the m12 connector. the m12 connector must b e only hand-tightened. if the m12 connector is not connected securely, the p roper 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 0.3 to 0 .5 n s m in o rder to ensure water resistivity. j maintenance and inspection cleaning use only water and mild detergent. do not use harsh chemicals or solvents. j operating environment do not install the e3g in locations with the following conditions. ? excessive dust. ? corrosive gases. ? directly e xposed to sprays of water, oil, or chemicals. ? directly e xposed to vibration o r shock.
