If there is no liquid in the pipe, the emitted beam will reach the receiver after it is refracted by the pipe. (Light incident.) Pipe Without liquid Receiver Emitter Pipe 2. If there is liquid in the pipe, the emitted beam will pass through the liquid and not reach the receiver. (Light interrupted.) With liquid Sensitivity selector (available only with EE-SPX613) Receiver Emitter If the diameter of the pipe is close to 6 mm, some of the emitted beam may reach the receiver because the angle of refraction is small, thus making the stable operation of the EE-SPX613 difficult. In such cases, set the sensitivity selector to Low and check that EE-SPX613 operation is stable. If there are floating materials on the surface on the liquid, some of the emitted beam may reach the receiver after it is reflected by the floating materials, thus making the stable operation of the EE-SPX613 difficult. In such cases, set the sensitivity selector to Low to stabilize operation. For normal use, set the sensitivity selector to High to account for reduced sensitivity caused by deterioration of the emitter due to age and stains on the pipe. 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 Make sure that this product is used within the rated ambient environment conditions. ● Nomenclature EE-SPX613 Operation selector Sensitivity selector Light indicator (red) Cable ● Mounting • The EE-SPX613 may not operate correctly if it is attached to an unsuitable pipe (e.g., opaque pipe). • Always use the supporting belts and slip protection tubes that are provided with the EE-SPX613 when attaching the EE-SPX613 to a pipe, as shown in the following illustration, and make sure that the pipe is in the center of the sensor slot and not separated from the pedestal. When tightening the supporting belts, make sure that the pipe will not be deformed. ● Adjustment • The EE-SPX613 requires 10 ms to be in stable operation after power is supplied. If separate power supplies are used for the EE-SPX613 and load, be sure to supply power to the EE-SPX613 before supplying power to the load. • Make sure that smoke, air bubbles, or water droplets are not able to form either inside or outside the pipe. Otherwise, a malfunction may occur. • Do not impose any force exceeding 5 N on the operation mode selector or sensitivity selector. ● Others Operating Environment • Do not use the EE-SPX613 outdoors. • Do not use the EE-SPX613 in places where water, oil, or chemical may be sprayed onto the EE-SPX613. The exterior coverings of the EE-SPX613 are made of polycarbonate. Keep the coverings away from any alkaline, aromatic hydrocarbon, or aliphatic chloride hydrocarbon solvents, all of which will damage the coverings. • Do not use the EE-SPX613 in places where the EE-SPX613 is subject to direct sunlight, corrosive gas or salt air. Supporting belts Slip protection tubes Pipe having a total cross-section area of 0.15 mm2. The total cable length must be 5 m maximum. Sensor Pedestal • When attaching the EE-SPX613 to a pipe with a supporting belt, make sure that the pipe will not be deformed. ● Wiring • Do not impose any excessive force on the cable. Do not pull the cable with any tractive force exceeding 30 N. • When extending the cable, use an extension cable with conductors 3 EE-SPX613 (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
