Observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
1. Installation Site
Do not install this product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Direct vibration or shock
• Reflection of intense light (such as other laser beams or electric arc-welding machines)
• Direct sunlight or near heaters
• Strong magnetic or electric field
Also, do not install this product in locations subjected to the following conditions due to
the degree of protection specified in the ratings:
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Water, oil, or chemical fumes or spray
2. Power Supply and Wiring
• When using a commercially available switching regulator, make sure that the FG
terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the
operating environment.
• Before turning ON the power after the product is connected, make sure that the power
supply voltage is correct, there are no incorrect connections (e.g. load short-circuit), and
the load current is appropriate. Incorrect wiring may result in breakdown of the product.
• Before connecting/disconnecting devices, make sure that the Sensor/Controller is
turned OFF. The Sensor or Controller may break down if it is connected/disconnected
while the power is ON.
• Use the extension cable sold separately for extending the cable between the Sensor
(receiver) and the Controller.

3. Warming Up
After turning the power supply ON, allow the product to stand for at least 10 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measurement values may fluctuate gradually.
4. Maintenance and Inspection
Do not use thinner, benzene, acetone or kerosene to clean the Sensor and Controller. If
large dust particles adhere to the filter on the front of the Sensor, use a blower brush
(used to clean camera lenses) to blow them off. Do not use breath from your mouth to
blow the dust off. To remove dust particles from the Sensor, wipe gently with a soft cloth
(for cleaning lenses) moistened with a small amount of alcohol. Do not use excessive
force to wipe off dust particles. Scratches to the filter might cause error.
