What to do if the bypass is not normal on a Huawei UPS?
If the bypass is not normal in your Huawei UPS, it could be due to a damaged bypass thyristor, which requires replacing the bypass module. Alternatively, if the bypass module is experiencing overtemperature, reduce the load or improve ventilation.
Why is the bypass abnormal in my Huawei Control Unit?
If the bypass of your Huawei Control Unit is abnormal, it could be due to a damaged bypass thyristor, in which case you should replace the bypass module. Alternatively, the bypass module might be experiencing overtemperature. To resolve this, try reducing the load or improving ventilation.
Why does my Huawei Control Unit UPS work in bypass mode?
If your Huawei Control Unit UPS works in bypass mode and does not transfer to inverter mode, it might be because the UPS is set to ECO mode. To resolve this, set the working mode correctly. Another reason could be that the number of bypass transfer times has reached the upper limit. In this case, choose 'Clear Faults' on the LCD.
What to do if the inverter is not normal in Huawei Power Supply?
If the inverter is not normal, it could be due to the UPS being overloaded or short-circuited. Try reducing the load or rectifying any short circuits. Ensure normal temperatures inside the equipment room by installing more air conditioners or ventilation devices. Alternatively, the power module may need replacement.
What to do if the Huawei Control Unit inverter is not normal?
If your Huawei Control Unit inverter isn't working normally, it might be due to an overload or a short circuit. Try reducing the load or fixing any short circuits. Alternatively, the power module could be faulty, in which case you should replace it.
Why is the Huawei Control Unit rectifier not working, and the bus voltage is not boosted?
If the rectifier of your Huawei Control Unit isn't working and the bus voltage isn't being boosted, it might be because the mains voltage is too high (above 280 V) or too low (below 80 V). Check the mains voltage against these thresholds, and if it's outside this range, contact the electric power company.
What to do if the bypass is not normal in Huawei UPS?
If the bypass function on your Huawei UPS is not working correctly, it could be due to a damaged bypass thyristor, requiring you to replace the bypass module. Alternatively, the bypass module might be experiencing overtemperature, in which case you should reduce the load or improve ventilation.
How to fix Huawei UPS5000-E UPS when it works in bypass mode?
If your Huawei UPS stays in bypass mode and doesn't switch to inverter mode, it might be because the bypass transfer times have reached their upper limit. To resolve this, clear the bypass transfer times on the LCD.
Why is the bypass abnormal in my Huawei UPS5000-E UPS?
If the bypass in your Huawei UPS is abnormal, it could be due to a damaged bypass thyristor, which requires replacing the bypass module. Also, consider reducing the load and improving ventilation to resolve the issue.
What to do if the inverter is not normal in Huawei Control Unit?
If the inverter in your Huawei Control Unit is not normal, it could be due to an output overload or a short-circuit. In this case, reduce the load or troubleshoot the short circuit. Alternatively, the power module itself might be faulty, requiring replacement.
