Wrong wiring will lead to breakdown or electrical shock of the instrument, please read this
operation manual clearly before installation.
zMake sure to remove AC power from the controller before wiring input, output connections,
and remove it before opening the controller housing.
zThe installation site of the controller should be a well ventiled area and out of direct sunlight.
zThe material of signal cable should be special coaxial cable. We strongly recommend using our
coaxial cable.
zAvoid electrical surges when using power, especially when using three-phase power. Use
ground wire correctly.
zThe internal relay contact of the instruments is for alarm or control function. To ensure safety,
please connect to external relay which can withstand enough amperage to allow safe
operation of the instruments.˄Please refer to chapter 3.6ʳ“Illustration of electrical
connectionϙ˅

at around 22mA. When the measurement value exceeds the lower limit of setting range,
the current output remains at 0mA under 0~20mA mode, or the current output remains
at around 2mA under 4~20mA mode. The phenomenon can be used as a judgment
reference of abnormality. If under HOLD status, the current output will remain at last
