Safety Precautions For common precautions, refer to www.ia.omron.com Fiber Amplifier Unit Warning Precautions for Correct Use This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. (1) Be sure to mount the unit to the DIN track until it clicks. (2) When using Amplifier Units with Wire-saving Connectors, attach the protective stickers (provided with E3X-CN-series Connectors) on the unused power pins to prevent electrical shock and short circuiting. When using Amplifier Units with Connectors for Communications Units, attach the protective caps (provided with Sensor Communications Unit).
(3) Do not use the product with voltage in excess of the rated voltage. Excess voltage may result in malfunction or fire. Never use the product with AC power supply. Otherwise, explosion may result. Amplifier Unit with Wire-saving Connector Amplifier Unit with Connector for Communications Unit Power Supply Connecting Terminal Protective Cap Precautions for Safe Use Protective Sticker The following precautions must be observed to ensure safe operation of the product. Doing so may cause damage or fire. (1) Do not install the product in the following locations.
• Locations subject to direct sunlight • Locations subject to condensation due to high humidity • Locations subject to corrosive gas Locations subject to vibration or mechanical shocks exceeding the rated values Locations subject to exposure to water, oil, chemicals • Locations subject to stream • Locations subjected to strong magnetic field or electric field (2) Do not use the product in environments subject to flammable or explosive gases. (3) Do not use the product in any atmosphere or environment that exceeds the ratings. (4) To secure the safety of operation and maintenance, do not install the product close to high-voltage devices and power devices.
(5) High-Voltage lines and power lines must be wired separately from this product. Wiring them together or placing them in the same duct may cause induction, resulting in malfunction or damage. (6) Do not apply load exceeding the ratings. Otherwise, damage or fire may result. (7) Do not short the load. Otherwise, damage or fire may result. (8) Connect the load correctly. (9) Do not miswire such as the polarity of the power supply. The length for the cable extension must be 30 m or less (or less than 10 m for S-mark certified models). Be sure to use a cable of at least 0.3 mm 2 for extension.
The power voltage must be 24 to 30 V when connecting amplifier units with extension cable and wire-saving connector. The length for the cable extension must be 30 m or less. Be sure to use a cable of at least 0.3 mm 2 for extension. (4) Do not apply the forces on the cord exceeding the following limits: Pull: 40N; torque: 0.1N·m; pressure: 20N; bending: 29.4N (5) Do not apply excessive force such as tension, compression or torsion to the Amplifier Unit with the Fiber Unit fixed to the Amplifier Unit. (6) Always keep the protective cover in place when using the Amplifier Unit. Not doing so may cause malfunction.
(7) It may take time until the received light intensity and measured value become stable immediately after the power is turned on depending on use environment. (8) The product is ready to operate 250 ms after the power supply is turned ON. (9) The Mobile Console E3X-MC11, E3X-MC11-SV2 and E3X-MC11-S cannot be connected. (10) Mutual interference prevention on the E3NX-FA Series does not function among the E3X-HD, E3X-DA-S, E3X-DA-N, E3X-SD, or E3X-NA Fiber Amplifier Units. The mutual interference prevention function on the E3X-ZV/MZV Series works only between the E3X-ZV/MZV Series.
Mutual interference prevention on the E3X-HD Series does function among the E3X-DA-S and E3X-MDA Fiber Amplifier Units. (11) If the unit receives excessive sensor light, the mutual interference prevention function may not work properly, resulting in malfunction of the unit. In such case, increase the threshold. (12) The E3NW-ECT Sensor Communications Unit can be used with the E3NX-FA0, but the E3X-DRT21-S, E3X-CRT, and E3X-ECT Sensor Communications Units cannot be used. The E3X-ZV/MZV Series cannot be used with Sensor Communications Units.
(13) If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or smoke immediately stop using the product, turn off the power, and consult your dealer. (14) Do not use thinner, benzine, acetone, and lamp oil for cleaning. (10) To use this device as connecting with each other, be sure to connect with the same power supply and turn ON the power simultaneously. Using a separate power supply will influence the functions when connecting the devices to use them. (11) Do not use the product if the case is damaged. (12) Burn injury may occur.
The product surface temperature rises depending on application conditions, such as the ambient temperature and the power supply voltage. Attention must be paid during operation or cleaning. (13) When setting the Sensor, be sure to check safety, such as by stopping the equipment. (14) Be sure to turn off the power supply before connecting or disconnecting wires. (15) Do not attempt to disassemble, repair, or modify the product Unit in any way. (16) When disposing of the product, treat it as industrial waste. (17) Do not use the Sensor in water, rain, or outdoors.
