Huaquan Generatortells you that the core processing method for controlling equipment to display public alarms includes checking the cause of the alarm.
Firstly, common causes of alarms include:
1. High water temperature: When the water temperature in the generator reaches 95 degrees or above, the high water temperature module will respond, causing the diesel engine to alarm and shut down to reduce the temperature.
2. Low oil pressure: When the oil level is below the warning position, the generator will sound an alarm and shut down.
3. Overcurrent protection: When the user's load exceeds the rated power of the generator, the generator will alarm and shut down.
4. Overload protection: This function is similar to overcurrent protection, protecting users from operating under overload.
5. Reverse power alarm: usually caused by inconsistent sag settings between two generators.
6. Stability issue of voltage sampling line: Loose voltage sampling line may cause voltage measurement failure and affect the operation of the generator.
7. Generator residual magnetism issue: Lack of residual magnetism can lead to ineffective establishment of the voltage system.
8. Grounding issue: When three-phase grounding is applied, the voltage and current will significantly decrease, and it is necessary to check the grounding equipment.
9. Performance of AVR pressure plate: Environmental changes may cause parameter failure and require inspection and adjustment.
10. Varistors and rectifier bridge diodes: Damage can cause abnormal voltage, affecting regulators and excitation devices.
The above are the reasons for the public alarm. We hope it can be helpful to you. The article is only for reference. Specific issues should be checked and repaired by professionals.Finally, some additional maintenance recommendations include regular checks on the cooling system, oil, and load conditions to ensure long-term stable operation of the generator.
