■
For wiring, please stop control unit, machinery and equipment, and turn off the power supply first. Drastic operation may lead to
unexpected motions, causing a danger. First, please attempt energizing test, then set the desired switch data while control unit,
machinery and equipment are stopped. Please discharge static electricity builted in body, tool and equipment before and during work.
Use a wire with elasticity as wire for robot connection in the movable part.
■
Please do not use the product beyond the power supply voltage range. If voltage more than its range is applied, or if alternating current
power (100VAC) is applied, it may cause a damage or burn.
■
This product and wiring must be installed as far away as possible from noise source such as strong electric line, etc. Please take other
countermeasures for a surge on the power supply line.
■
Please do not short-circuit a load, or causing damage or burn.
■
Output impedance of analog voltage output type is approximately 1 kΩ. If the impedance of connecting load is low, error of output value
becomes large. Please check the error of connecting load impedance before use. However, analog current output type is excluded.

■
If a switch is activated in unstable flow rate state such as a fluid pulsation, etc., unstable operation may be provided. In this case,
maintain a sufficient difference between two set points, or avoid switch setting in the unstable area, then use the product after checking
that switching operation becomes stabilized.
