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 abnormal in Huawei UPS5000-E UPS?
If the inverter of your Huawei UPS is abnormal, it might be due to several reasons. First, there might be an output overload or a short-circuit. In this case, you should reduce the load or troubleshoot the short circuit. Secondly, the inverter may be overheated. To solve this, install more smart cooling products or ventilation devices to ensure normal temperature inside the data center. Finally, the power module could be faulty, requiring you to replace it.
Why is the rectifier abnormal in my Huawei UPS5000-E UPS?
If the rectifier is abnormal in your Huawei UPS, it could be due to a few reasons. The mains voltage might exceed the upper threshold of 280 V or be less than the lower threshold of 80 V. In this case, check whether the mains voltage is beyond the allowed range, and if it is, contact the electric power company. Alternatively, the PFC soft-start might have failed, or the power module itself could be faulty. In either of these cases, replace the power module.
What to do if the charger generates an alarm in Huawei UPS?
If the charger generates an alarm in your Huawei UPS, it could be due to a few reasons. The charger itself might have failed, or it could be experiencing overcurrent or undervoltage. In the case of charger failure or overcurrent, replace the power module. If it's experiencing undervoltage, check whether the number of batteries is correct. If the number of batteries is correct but the alarm persists, replace the power module.
Why does my Huawei UPS work in bypass mode?
If your Huawei UPS works in bypass mode and does not transfer to inverter mode, it could 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. If this is the case, reset the bypass transfer times on the LCD.
What causes an abnormal bypass in Huawei UPS?
If the bypass is abnormal in your Huawei UPS, it could be due to the bypass thyristor being damaged, in which case you should replace the bypass module. Alternatively, the bypass module may be experiencing overtemperature. To resolve this, reduce the load or improve ventilation.
How to fix an abnormal ATS in Huawei UPS5000-E?
If the ATS (Automatic Transfer Switch) is abnormal in your Huawei UPS, the input three-phase sequence might be incorrect. To fix this, power off the ATS and check the phase sequence.
What to do if the Huawei UPS inverter is not normal?
If the inverter is not normal, it could be due to several reasons. First, the UPS might be overloaded or short-circuited; in this case, reduce the load or rectify any short circuits. Second, inverter overtemperature could occur. To solve this, install more smart cooling products or ventilation devices to ensure normal temperatures inside the equipment room. Finally, consider replacing the power module.
What to do if Huawei UPS5000-E UPS charger generates an alarm?
If the charger generates an alarm, there are several possible causes. The charger might have failed or experienced overcurrent. In both cases, replace the power module. Also, the charger may be experiencing undervoltage. Check whether the configured number of batteries is correct. If the value is correct but the alarm persists, replace the power module.
