1) Check whether the set sensor range upper limit or sensor limit range is greater than or equal to the current measured signal, and determine the correctness of the selected sensor model and set range;
2) Check whether the impulse pipe has leakage or blockage. If the impulse valve is used, check whether the valve is fully opened; 3) Confirm that the introduced measured signal is a stable input; If the measured gas is liquid, confirm that there is no residual gas; If the measured gas is dry, confirm that there is no liquid;
4) Check whether there is sediment on the sensor flange and whether the flange is corroded;
5) If it is a remote flange type transmitter, check whether there is a potential difference between the two measured signals, and calculate whether the differential pressure caused by the potential difference is greater than the sensor range;
6) Check whether the power supply is between 12V and 24VDC;
7) Use the hand-held operator to conduct self-inspection and parameter reading on the instrument to check whether the intelligent electronic components are faulty or uninitialized.

PFEA111-20 For the load with frequent on-off, two-way thyristor output or transistor output should be selected. They are non-contact components. However, the output of bidirectional thyristor can only be used for AC load, while the output of transistor can only be used for DC load. The selection of output wiring mode is based on the different output wiring modes of PLC. There are generally two types of output: grouped output and separated output,
PFEA111-20 group output is a group of several output points that share a common terminal. Each group is separated, and different power supplies can be used separately. Each output point of the separated output has a common terminal, and the output points are isolated from each other. PFEA111-20 can use different power supplies for each output point. It mainly depends on the power supply type of the system load. Generally, integrated PLC has both grouped output and separated output.
