The wrong range corresponds to the PLC calculation error. For the range, please refer to the technical specifications in the first part. 2. The wiring method is incorrect or the wiring sequence is wrong. 4. The distance between the transmitter and the collector is too long, causing signal disorder. 5. The PLC acquisition port is damaged. 6. Equipment damage.
