Unless avoided, death or serious injuries might be caused. [IMPORTANT] PRECAUTIONSCAUTION: A potentially dangerous state depending on usage. Unless avoided, death or injuries might be caused. NOTE: A potentially dangerous state depending on usage. Unless avoided, low-grade to moderate injuries might be caused, or property might be damaged. (Cylinders) CAUTION Check the air cylinder specifications and use the cylinder within the allowed specification range. If the cylinder is used under pressure or temperature exceeding the specifications, or any fluid other than compressed air is used, there is a danger of personal injury or damage to the machine by broken or malfunctioning cylinders. Be sure to use the cylinder within the allowed specification range. Please note that there may be potential damages to the machine or human body, e.g, hands and/ or legs being caught in the moving mechanisms. If there are potential hazards to human body, install a protective cover as a safety measure. Provide safety measures against possible injuries and equipment damages by air cylinder malfunctions due to power and air supply troubles. The air cylinder and the coupling with other equipment must be fixed securely to avoid loosening. (Cylinders) NOTE Use a filter and a dryer in order to supply clean and dry compressed air to the air cylinder. Impurities in the compressed air may cause malfunctions. Use a speed controller to operate the air cylinder at a predetermined speed. A lateral load beyond the allowable range must not be applied to the piston rod. Otherwise, the air cylinder may operate improperly, or the gaskets may be damaged. The air cylinder can be operated without lubrication. For lubricating the cylinder, supply Category-1 turbine oil (ISO VG32). Once lubricated, continue to use the same lubricant. If lubrication is stopped, the initial lubricant may be lost, thus causing the cylinder to malfunction. (Sensors for Cylinders) DANGER Never use the cylinder in an atmosphere containing explosion gas. Otherwise, the sensor may cause an explosion because it does not have an explosion-proof structure. (Sensors for Cylinders) CAUTION After reviewing the specifications of sensors for cylinders, use them within the specifications. If the sensor is used with a load current, voltage, temperature, impact, or any other condition outside the range of the specifications, the sensor may break the sensor may break or operate improperly. Do not use the sensor under conditions such as: a magnetized area; an atmosphere containing an explosive gas; water or oil may be splashed to the cylinder; the temperature may change in an extremely wide range; an impact may occur; a dusty area. Otherwise, the sensor may operate improperly or break. Perform wiring correctly according to the color-coded labels of the sensor lead wires. <Contacting Sensor> t If the wiring is reversed, the lamp will not light, although the sensor operates. (24 VDC only) <Two-wire Non-contact Sensor> t If the wiring is reversed, the lamp will continually stay ON. <Three-wire Non-contact Sensor> t If the power and output lines are wired incorrectly, the sensor will break. To connect a load that generates a surge voltage (e.g. relay), use a switch that contains a contact protection circuit, or use a protection circuit. If power is turned on without connecting a load such as relay, PLC (programmable controller) or a similar load to the two-wire sensor, the sensor will fail. Be sure to connect a load before turning the power on. Do not bundle sensor wires with power lines or high voltage circuits. Otherwise, noise may be generated, resulting in malfunction of the sensor. If the wire contains insulation faults, an over-current may flow through the sensor, causing the sensor to fail. Confirm that there is no insulation fault. If the sensor wire is too long, turning power on may generate a in-rush current, resulting in breakage of the contacts. If the wire length exceeds 5m, be sure to connect a contact protection circuit. Do not drop or bump the sensor, as the internal mechanism of the sensor may break. Fix the sensor in accordance with the tightening torque specifications.
