If the problem of measurement mode and range sticking is eliminated, the problem still exists, it may be that the common mode voltage is too high. The experience of Manufacturing Co., Ltd. is to use an analog signal isolator or, subsequently, A 4-wire signal to access the BI01 BI01-A-V001 module.
How to avoid BI01 BI01-A-V001 module exceeding the common mode voltage (Ucm) and how to avoid subsequent overflows or underflows?
When the input is open and connected to a zero-potential measuring transmitter, the common-mode voltage value may be slightly exceeded. Therefore, the following measures must be taken for isolated 4-wire measurement transmitters, zero-potential voltage sensors, and isolated thermocouples:
① M-input terminal must be connected to the module ground;

MANA must also be grounded;
③ Ground the unused COMP terminal;
BI01 BI01-A-V001 Precautions: If these measures are not taken, the measurement value of the normal working measurement transmitter may also have A bad value.
Channel group input processing:
① If both inputs of the channel group are not in use, insert the measuring range module into the “D” setting;
② If one input of the channel group is not used;
③ Please refer to the instructions in the 4-20mA measuring range manual;
④ Short-circuit the open input of the voltage/thermocouple measurement range (connect M and M- together) and ground it
