SET 5 E8F2 Safety Precautions Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use this product in atmospheres or environments that exceed product ratings. ● Installation Do not use the Sensor in an environment subject to corrosive or combustible gas. ● Wiring If no linear output is used, cut the gray lead wire short and apply insulating tape to the lead wire so that it will not come into contact with any other terminal. ● Adjustments • Filter the gas with an appropriate air filter so that the applied gas will be free of moisture or oil. • Be sure to use the Sensor under the rated pressure. • When setting the set pressure of the ON or OFF point of the output transistor by pressing the mode selection key, use a manometer if precise pressure settings are required. The Sensor has a display error of ±3% FS±1 digit at room temperature. Refer to Display accuracy in Ratings and Specifications. • Turning ON the power The Sensor is ready to operate 0.5 s after it is turned ON. When the load and Sensor are connected to separate power supplies, be sure to turn ON the Sensor first. ● Others Make sure the Sensor does not get wet. ● Mounting • Do not apply a tensile strength in excess of 50 N to the cables or connectors. • The pressure port (made of aluminum die-cast) is fixed with tapered R(PT) 1/8 male screws and M5 female screws. When using tapered screws, use tapered Rc(PT) 1/8 female screws. • Wrap the tapered R(PT) 1/8 male screws with sealing tape to prevent any leakage. Tighten the male screws to a torque of 10 N·m max. • Tighten M5 female screws to a torque of 2 N·m max. • Tighten each male screw by using a 12-mm wrench to hold its hexagonal head, not its body. E8F2 Hexagonal head • When attaching the Mounting Bracket to the Sensor, make sure that each M3 screw is tightened to a torque of 0.5 N·m max. 6 E8F2 Dimensions (Unit: mm) Sensors E8F2 Display panel 28 1.5 2 27 (29) 25.5 (17) 9 8 Pressure port Two, M3 depth 6 R(PT) 1/8 M5 depth 8 28 20 27 13.5 5 20.5 6 20 4-dia. vinyl-insulated round cable with 5 conductors (Conductor cross-section: 0.15 mm2, Insulator diameter: 0.9 mm), Standard length: 2 m Mounting Hole Dimensions With Mounting Bracket Attached Two, M3 20.5 29 27 15 20 5.4 20 42 28.5 15 Accessories (Order Separately) Mounting Bracket E89-F3 20.5 15±0.4 9 Two, 3.5 dia. 27 20 14.5 Four, R1 13.5 20 45˚ 26.9 4.5 90˚±0. 5 Note: Provided with the E8F2.
