E3T will be in most reliable operation without being influenced by temperature change, voltage fluctuation, dust, or setting change. If Load short-circuit protection the operating level cannot be set to the stable operation range, pay attention to environmental changes while operating the E3T. The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF. Then, Use of E39-E10 Sensitivity Adjustment Unit recheck the wiring and turn on the E3T again to reset the load short- (Dark-ON: E3T-ST12) circuit protection function. The load short-circuit protection function will work if there is a current flow that is 1.5 times larger than the rated (At Min) (At Center) (At Max.) load current. When using a capacitance load, be sure that the inrush Indicator current will not exceed 1.5 times larger than the rated current. Adjuster Mounting When mounting the Sensor, never strike it with a heavy object, such as a hammer. Doing so may reduce its watertight properties. Use screws with spring, flat, or toothed washers to secure the Sensor. Tightening Torque 1. Mount the Unit on the Receiver. M2-mounting Sensors: 0.15 N·m max 2.
