Common Problems and Solutions: When there is no output or output error, the possible reasons are:1. The corresponding error of the range leads to an error in the PLC calculation. 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. The equipment is damaged.
