e3t 13 safety precautions refer to warranty and limitations of liability . this product is not designed or rated for ensuring safety of persons. do not use it for such purpose. do not apply ac power to the e3t, otherwise the e3t may rupture. do not use the product in atmospheres or environments that exceed product ratings. wiring the maximum power supply voltage is 26.4 vdc. before turning the power on, make sure that the power supply voltage be not more than maximum voltage. load short-circuit protection the e3t incorporates a load short- circuit protection function. if the load short-circuits, the output of the e3t will be turned off. then, 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 t hat is 1.5 times larger than the rated load current. when using a capacitance load, be sure that the inrush current will not exceed 1.5 times larger than the rated current. mounting when mounting the sensor, never strike it with a heavy object, such as a hammer. doing so may reduc e its watertight properties. use screws with spring, flat, or toothed washers to secure the sensor. tightening torque m2-mounting sensors: 0.15 nm max m3-mounting sensors: 0.5 nm max small cylindrical sensors: 1 nm max mounting the sensor on moving parts consider models that use break resistant cables (e.g., robotics cables) if the sensor will be mounted on a moving part, such as a robot hand. the flexing resistance of robotics cable at approximately 400 thousand times is far superior to that of standard cable at approximately 14 thousand times. cable bending rupture test (tough cable breaking test) the cable is repeatedly bent with power supplied to check the number of bends until the current is turned off. adjusting indicators ? the following graphs indicate the status of each operating level. ? be sure to use the e3t within the stable operating range. use of e39-e10 sensitivity adjustment unit (dark-on: e3t-st12) 1. mount the unit on the receiver. 2. set the adjuster of the sensitivity adjustment unit to max. (before shipping: max.) 3. after mounting on the sensor, adjus t the optical axis and secure the sensor. 4. place a workpiece between the emitter and receiver and gradually turn the adjuster counterclockwise toward the min. side. stop turning the adjuster when the operation indicator and stability indicator (green) turn on. 5. remove the workpiece and confirm that the operation indicator is off and the stability indicator (green) is on. this completes the adjustment. note: if the light attenuation rate due to a workpiece is 40% or less, the stability indicator will not turn on whether or not light is received. when the variation of light is small such as when sensing semi-transparent workpieces, carefully perform preliminary testing. e3t-cd@@ sensitivity adjustment use the special screwdriver that is provided with the sensor to adjust the sensitivity. do not exceed 0.8 nm when turning the adjuster. others do not install the e3t in the following locations. ? locations subject to excessive dust or dirt ? locations subject to direct sunlight ? locations subject to corrosive gas ? locations subject to cont act with organic solvents ? locations subject to vibration and shock ? locations subject to contact wi th water, oil, or chemicals ? locations subject to high humid ities that might result in condensation warning precautions for correct use specimen standard cable 2.4-mm dia.
