How to Deal with the Electrical Control System Failure of Concrete Mixing Station
In the long-term daily production and operation of concrete mixing station, it is inevitable that there will be failures in mechanical equipment and control system. Today, the auxiliary mechanical mixing station mainly tells you about the possible faults of the electrical control system of the mixing station and the countermeasures! 1. PLC cannot communicate Due to poor contact of communication line or communication network connector, or damage of communication and expansion module, the PLC electronic system fails. Therefore, the communication line, communication connector and communication expansion module can be inspected and replaced. 2. The digital display meter is garbled or the power supply is out of phase When the digital display meter is garbled, it can be checked step by step and then replaced; The lack of phase of external power supply is due to the burnt contact of contactor or circuit breaker, the current of circuit breaker is not set properly or the burnt contact of contactor causes the lack of phase; Elimination method: the power supply can be checked and updated. If the circuit breaker is found to...
