If the Analog Input Unit malfunctions due to external noise through the power
line to the Analog Input Unit, insert a noise filter to the power line. The Analog
Input Unit may be influenced by noise if the Analog Input Unit and an electric
welding machine share a single power source or if the Analog Input Unit is
operated near a machine that generates high-frequency electromagnetic
waves.
Use a twisted-pair cable for the input wiring to the Analog Input Unit.
