If the line breakage occurs at point A or B as shown in the preceding diagram
while power is shared by the connected devices, a short-circuit line will be
formed as indicated by the dotted line in the above illustration, thus generating a
voltage of approximately one-third to two-thirds of the voltage output from the
connected device. If this kind of voltage is generated while using the Unit at 1 to
5 V, the line breakage may not be detected. If the line breakage occurs at point
C, it will not be detected because the negative (–) side is common.
In case of the current input, this kind of problem will not occur even if the power
supply is shared by the connected devices.

Note 1. When using current inputs, the voltage input terminals (V+) and current in-
put terminals (I+) must be individually short-circuited as shown in the above
diagram.
2. For inputs that are not used, either set to "0: Do not use" in the input number
settings (refer to 2-5-1 Setting Inputs and Signal Ranges) or short-circuit the
voltage input terminals (V+) and (V–).
3. Crimp-type terminals must be used for terminal connections, and the
screws must be tightened securely. Use M3 screws and tighten them to a
torque of 0.5 N S m.
Connecting shielded cable to the Unit's COM terminals (A3, A10, B6, B13)
can improve noise resistance.
