Power supply Do not impose an excessive voltage on the E2Q2, otherwise it may explode or burn. Do not impose AC voltage on any E2Q2 DC model, otherwise it may explode or burn. When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-- transformer. Sensing Object Metal coating: The sensing distance of the proximity sensor will vary with the metal coating on sensing objects. J WIRING Brown Load Black Sensor Incorrect Blue Do not connect the AC types without load to the power supply. The sensor will be damaged. High-- Tension Lines Wiring through Metal Conduit If there is a power or high-- tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. J MOUNTING The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water resistance. J ENVIRONMENT Sensor Water Resistance Do not use the proximity sensor underwater, outdoors or in the rain. Operating Environment J INSTALLATION Power Reset Time The Proximity Sensor is ready to operate within 300 ms after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. Power OFF Be sure to use the Proximity Sensor with operating ambient temperature range and do not use the Proximity Sensor outdoors so that its reliability and life expectancy can be maintained. Although the Proximity Sensor is water resistant, a cover to protect he proximity sensor from water or soluble machining oil is recommended so that its reliability and life expectancy can be maintained. Do not use the Proximity Sensor in an environment with chemical gas (e.g., strong alkaline or acid gases including nitric, chromic, and concentrated sulfuric acid gases). The Proximity Sensor may output a pulse signal when it is turned off. Therefore, it is recommended to turn off the load before turning off the Proximity Sensor.
