OPERATION
The EE-SPX613 detects the level of liquid by detecting the difference in refractive index between the air and liquid. 1. If there is no liquid in the pipe, the emitted beam will reach the receiver after it is refracted by the pipe.
Pipe
If the diameter of the pipe is close to 6 mm, some of the emitted light may reach the receiver because the angle of refraction is small. This may result in false readings. In such cases, set the sensitivity selector to Low and check that the EE-SPX613 reads correctly for pipes with and without liquid. If there are floating materials on the surface of the liquid, light reflected from the floating material may reach the receiver. In such cases, set the sensitivity selector to Low and check the operation of the EE-SPX613 for pipes with and without liquid. If transmission of the light is impaired by stains on the pipe or an emitter that has deteriorated with age, you may need to set the sensitivity to HIGH.

Precautions
! WARNING
* Do not supply or impose on the EE-SPX613 any AC current or voltage exceeding the upper limit of the rated voltage range, or the EE-SPX613 may be damaged. * Do not short-circuit the load connected to the EE-SPX613, or the EE-SPX613 may be damaged.

! Caution
Mounting
Always use supporting belts and slip protection tubes, which are provided with the EE-SPX613, when attaching the EE-SPX613 to an appropriate pipe, as shown in the following illustration. Make sure that the pipe is in the center of the sensor groove and not lifted from the pedestal. When tightening the supporting belts, make sure that the pipe will not be deformed.
Slip protection tubes Supporting belts
Power Supply
Ground the FG and GND terminals if a standard switching regulator is used to supply power to the EE-SPX613, or the EE-SPX613 may malfunction .
Operating Environment
The EE-SPX613 is not watertight. Do not use the EE-SPX613 outdoors. Do not use the EE-SPX613 in places where water, oil, or chemicals may splash or be sprayed onto the unit. The exterior coverings of the EE-SPX613 are made of polycarbonate. Keep the coverings away from any alkaline, aromatic hydrocarbon, or aliphatic chloride hydrocarbon solvent, all of which will damage the coverings.

Others
* The EE-SPX613 requires 10 ms to be in stable operation after power is supplied. If two power supplies are used for the EE-SPX613 and load respectively, be sure to supply power to the EE-SPX613 before supplying power to the load. If there is a high-tension line near the cable, wire the cable through an independent metal conduit to protect the EE-SPX613 from damage or malfunction. Do not attach the EE-SPX613 to improper pipes, such as non-transparent pipes, or the EE-SPX613 may not operate properly. * * Do not impose any excessive force on the cable. Do not pull the cable with a force exceeding 30 N. Use an extension cable with conductors having a total crosssectional area of 0.15 mm2 (i.e., AWG26) and a total cable length of 5 m maximum. Do not impose a force exceeding 5 N on the operation mode selector or sensitivity selector.
