Do not short-circuit the load connected to the E3T. When supplying power to the E3T, make sure that the polarity of the power is correct. J OPERATING ENVIRONMENT To avoid malfunction, DO NOT install the E3T in the following environments: • • • • Locations where the E3T is exposed to intense sunlight. Locations with high humidity and where condensation may result. Locations with corrosive gas. Locations with vibration or shock affecting the E3T. J HIGH-TENSION LINES To avoid Sensor damage or malfunctioning due to induction noise, do not place the power supply lines of the Photoelectric Sensor within the same conduit as power lines or high-tension lines. The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF. Recheck the wiring and turn on the E3T again to reset the load short-circuit protection function. The load short-circuit protection function will work if there is a current flow that is 2.4 times larger than the rated load current. When using an inductance load, be sure that the inrush current will not exceed 2.4 times larger than the rated current. J CLEANING DO NOT apply paint thinner when cleaning the E3T. Paint thinner will damage the casing of the E3T. J INDICATORS The following graphs indicate the status of each operation level. Be sure to use the E3T within the stable operating range. Stable operation range Unstable operation range Stable operation range J CABLE The cable can be extended up to 100 m provided that cable thickness does not exceed the 0.3 mm2 maximum. Light ! Avoid damage to the E3T: NEVER apply AC power to the E3T. Note: J POWER SUPPLIES Stability indicator (green) ON Operation level x 1.2 Operation level Operation indicator (orange) E3T-jjj1 E3T-jjj2 E3T-jjj3 E3T-jjj4 ON OFF OFF ON OFF Operation level x 0.8 ON When the E3T’s operation level is set to the stable operation range, the E3T will be in its most reliable operation without being influenced by temperature, voltage fluctuation, dust, or mounting changes. If a switching regulator is connected to the E3T, you must ground the FG (frame ground) and G (ground) terminals, or the switching noise of the switching regulator may cause the E3T to malfunction. J TURNING ON POWER SUPPLY J WATER RESISTANCE • • • Do not use the E3T underwater, outdoors, or in the rain. Use M2 screws and washers to mount the E3T. When mounting the E3T, NEVER strike the E3T with a hammer, or the E3T will lose its watertight properties. • The E3T will be ready for sensing 100 ms after the power is turned ON. If the E3T is connected to a power source different from one for loads, be sure to turn ON the power supply to the E3T first. NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
