Troubleshooting methods for switching power supply systems such as Emerson
1. Troubleshooting process of power supply systems such as Emerson, Huawei, ZTE, Power Source, and Zhongda:
1. Muffler.
2. Observe the fault indicator of the power distribution unit and the fault indicator of the module for preliminary fault location.
3. Enter the monitoring module to query the fault information.
4. Record the status of the fault indicator on the panel of the power distribution unit, monitor all the fault information of the module and the status of the fault and protection indicator on the module panel.
5. Fault classification (DC, AC, module, battery, monitoring).
6. Analyze the cause of the failure according to the type of failure (consider in turn: parameter setting error → address error → communication line connection is normal → signal acquisition line connection is normal → module failure → board, device failure).
7. Perform corresponding troubleshooting.
8. Record the processing steps and the relevant data measured during the processing.
9. Perform another information query to confirm that all faults have been eliminated.
10. Fill in the result of troubleshooting.
