Tighten the Fiber Unit with a screwdriver to a torque of 0.2 N*m. When supplying power to the E3MC, make sure that the polarity of the power is correct, otherwise the E3MC may be damaged. Do not short-circuit the load connected to the E3MC, otherwise the E3MC may be damaged. Among the recommended fibers, the E32-CC200 and E32-D32L have white or dotted yellow lines on the fiber to be inserted into the emitter. When using the E3MC-(M)Y@@, insert the fiber with the line into the emitter section at the bottom of the amp. Optical Fiber Type Fiber Unit Tightening Torque Tightening Torque The Fiber Unit must be tightened to a maximum torque of 0.54 N*m. When mounting the Fiber Unit, refer to the following table and make sure that the tightening torque applied is correct. Mounting Fibers Screw-mounting Type Mounting bracket When Fiber Units are mounted to face each other, make sure to adjust the optical axes so that the Fiber Units will not be mutually interfered. Toothed washer Handling the Fiber Unit Do not pull or press the Fiber Unit. Lock nuts (provided with the E3MC) Do not bend the Fiber Unit beyond 10 mm. Do not bend the edge of the Fiber Unit. Column Type 20 mm min. Correct Sensor head Flat or pan head set screw (M3 max.) Amplifier Unit 20 mm min. Fiber Unit Incorrect Sensor head Amplifier Unit Do not apply excess force on the Fiber Unit. Correct Fiber Unit Tightening torque M3 screw M4 screw 0.78 N*m max. M6 screw 0.98 N*m max. 2-dia. column 0.29 N*m max. 3-dia. column 0.29 N*m max. E32-T16 0.49 N*m max. Make sure that the size of the wrench applied to the nut is correct. Nylon wire holder Incorrect Fiber Cutting The Fiber Head could be broken by excessive vibration. To prevent this, the following is effective: Insert the fiber into one of the insertion holes of the Cutting Tool to cut the fiber to the desired length. Press down the blade of the Cutting Tool to cut the fiber in a single stroke. Do not stop the Cutting Tool midway. A one-turn loop can absorb vibrations. Tape View hole General-purpose Optical Fiber Type Insertion The inserted Fiber Unit comes in contact with the internal rubber packing first. Insert the Fiber Unit further until it comes in contact with the innermost end. 18 Each insertion hole can be used only once. Do not use it again, otherwise the fiber may not be cut properly and the sensing distance may decrease. E3MC E3MC Installation Connection Do not pull the Fiber Unit with force exceeding 9.8 N or press the Fiber Unit with force exceeding 29.4 N. The fiber is so thin that the utmost attention will be required to handle the fiber. Do not bend the Fiber Unit beyond the permissible bending radius provided in Ratings/Characteristics. Do not bend the end of the Fiber Unit. 20 mm min. Power Reset Time The E3MC is ready to sense objects from 100 ms after the E3MC is turned ON, until when no devices connected the E3MC can be used. Be sure to turn ON the E3MC first if power is supplied to the E3MC and the load independently. When the E3MC is turned ON or OFF, the operation indicator will be ON for an instant but no control output will be turned ON. When using the Sensor for fine sensing, allow the system to warm up for approximately 15 min after turning ON the power supply. Power OFF Fiber Unit Amplifier 20 mm min. The E3MC may output a single pulse when the control power supply is turned OFF. If the E3MC is connected to a timer or counter to which power is supplied from an independent power supply, the E3MC will be more likely to output a single pulse when the control power supply is turned OFF. Therefore, supply power to the timer or counter from the same power supply for the E3MC. Types of Power Supplies Amplifier Fiber Unit No full-wave or half-wave rectified power supplies can be connected to the E3MC. Power Supplies Do not press or place a load on the Fiber Unit. Correct Fiber Unit Nylon wire holder Be sure to ground the FG (frame ground) and G (ground) terminals if a switching regulator is connected to the E3MC, otherwise the E3MC may malfunction due to the switching noise of the switching regulator. Wiring Cord The cord can be extended up to 100 m provided that the thickness of the cord is 0.3 mm2 maximum. Incorrect Repeated Bending The cord must not be bent repeatedly. High-tension Lines The Fiber Head can be broken by excessive vibration. To prevent this, the following is effective. A one-turn loop can absorb vibrations. The power supply lines of the Photoelectric Sensor must not be wired alongside power lines or high-tension lines in the same conduit, otherwise the Photoelectric Sensor may become damaged or malfunction due to induction noise that may be generated from the power lines or high-tension lines. Route the lines separately or in a single conduit. Cord Pulling Force Do not pull cords with pulling forces exceeding 50 N. Tape Others Built-in Amplifier Type Tightening Torque The Amplifier Unit must be tightened to a maximum torque of 2.3 N*m. Mounting When Sensors are mounted to face each other, make sure to adjust the optical axes so that the Sensors will not be mutually interfered. EEPROM Error An EEPROM error may result if power supply to the Sensor fails or the Sensor is influenced by static noise. The operation and bank indicators will flash and the buzzer will beep if there is an EEPROM error, in which case perform teaching and make threshold level settings again. M12 Metal Connector Make sure to connect or disconnect the metal connector after turning off the E3MC. Make sure to hold the connector cover when connecting or disconnecting the metal connector. Tighten the metal connector securely by hand. Do not use any tool, such as pliers, otherwise the metal connector may be damaged. If the metal connector is not tightened securely, the metal connector may be disconnected by vibration or the proper degree of protection of the E3MC may not be maintained. Water Precaution Avoid using the Sensor in water, rain, or outdoors. Protective Cover Tighten the operation cover to a torque of 0.2 to 0.3 N*m to ensure proper waterproofing. 19 E3MC E3MC DIN Track Mounting/Removal with the E39-L115 Mounting 1.
