The following conventions are used to indicate and classify precautions in this manual. Failure to heed precautions can result in injury to people or damage to property. !DANGER !WARNING Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. [. . . ] If teaching is unsuccessful, the teaching indicator (orange) will flash, in which case change the 156 Operation without CQM1-TU001 Remote Console Section 4-1 position of the object and the sensing distance that have been set and repeat from step 3. Background object With sensing object Mark not detected 5. Set the mode selector to RUN to complete the sensitivity setting on the E3X-MA11. Light Axis Adjustment with Flashing Function If the light projection fiber head axis and the light reception fiber head axis do not agree with each other, and the amount of light received becomes 90% of the peak value or less, the flashing function of the E3C-MA11 will operate. The E3C-MA11 retains the peak value when the mode selector is set to SET so that the axes of the fiber heads can be easily adjusted to agree with each other. When the axes agree, the indicator on the light projection fiber head will be lit. The E3C-DS10T does not incorporate an indicator on the light projection fiber head. The indicator on the light projection fiber head will work as an operation indicator when the E3C-MA11 is in RUN mode. Indicator Sensor head for light emission Optical input Sensor head for light reception The peak of light reception 90% of the peak value Lit in this range. Angle of the head () Flashing Lit Flashing 4-1-3 E2C-MA11 Proximity Sensor Module Be sure to perform teaching before using the E2C-MA11 Proximity Sensor Module. Sensitivity Adjustment Teaching without a Sensing Object 1, 2, 3. . . There are three sensitivity adjustment methods. Teaching without a sensing object is recommended when using the E2CMA11 as a standard proximity sensor. Set the mode selector to SET. 157 Operation without CQM1-TU001 Remote Console Section 4-1 3. Set the mode selector to RUN to complete the sensitivity setting on the E2C-MA11. l ON point The ON point will be automatically set at the maximum value of the stable sensing distance. If teaching is unsuccessful, the stability operation indicator will flash. In this case make sure that the optical fiber cable of the sensor is connected securely and that there is no sensing object, and then repeat from step 3. Teaching with a sensing object is recommended for sensing level differences or double-sheet detection. Place the object at the sensing position at which the desired output will be OFF and press the teaching button. l1 Desired output at l 1 : OFF The teaching indicator will turn orange. Move the object to the position where you want to turn ON the output and press the teaching button. If teaching is successful, the teaching indicator will turn from orange to green. l2 Desired output at l 2 : ON 5. Set the mode selector to RUN to complete the sensitivity setting on the E3X-MA11. If teaching is unsuccessful, the teaching indicator (orange) will flash, in which case check that the sensor cable is connected, change the position of the object and the sensing distance that have been set, and repeat from step 3. ON point l2 l1 158 Operation without CQM1-TU001 Remote Console Section 4-1 Note The sensor may not properly reset after detection when teaching detection of subtle changes. Always check to be sure the sensor is resetting even if the indicator shows that teaching is OK. Teaching for position control is recommended when specifying the ON point for the detection of objects which are too close. Move the object to the position where you want the output ON and press the teaching button. If teaching is successful, the teaching indicator will turn from orange to green. l 5.
