How to troubleshoot a Huawei UPS with a blank LCD screen?
If the mains switch is ON, but the LCD of your Huawei UPS does not display anything and the system does not perform self-tests, check the input power cable connection. Also, use a multimeter to check that the UPS input voltage meets specifications, as the input voltage may exceed the limit.
What to do if the AC input indicator is off on my Huawei UPS2000-G-15KRTL UPS?
If the AC input indicator is off and the UPS is running on battery despite normal mains, it could be due to the UPS mains switch being OFF. Ensure the UPS mains switch is turned ON. Alternatively, the input cable may not be properly connected; check the UPS input power cable connection.
What to do if the battery indicator blinks on my Huawei UPS2000-G-15KRTL?
If the battery indicator is blinking and the buzzer is buzzing, it indicates that the UPS is about to shut down due to insufficient battery reserve. To prevent data loss or damage, immediately save load data and shut down primary loads. Also, verify that the number of batteries and battery capacity are correctly set based on the actual configuration.
Why is the mains indicator off on my Huawei UPS2000-G-15KRTL UPS?
The mains indicator might be off because the mains voltage or frequency exceeds the UPS input range. Use a multimeter to verify that the input voltage and frequency meet the specified requirements.
How to fix a Huawei UPS when the LCD displays nothing?
If the LCD displays nothing and the system doesn't perform self-tests, first check the UPS input power cable connection to ensure the input power supply is properly connected. Also, use a voltmeter to check whether the UPS input voltage meets the required specifications, as it may be less than the lower threshold or greater than the upper threshold.
What to do if Huawei UPS does not start?
If the UPS does not start after pressing the power button, ensure that you press it for more than 5 seconds until you hear a beep sound.
What to do if my Huawei UPS is making abnormal noises?
If abnormal noises or smells are coming from the Huawei UPS cabinet, shut down the UPS immediately and cut off the input power supply. Then, contact local Huawei technical support.
How to extend battery discharge time on Huawei UPS?
If the battery discharge time of your Huawei UPS is much less than the standard time, it could be due to batteries not being fully charged. Charge the batteries for more than 8 hours when the mains is normal and then test the discharge time again. If the issue persists, the battery performance may have deteriorated, and you should contact local Huawei technical support to replace the batteries.
What to do if the battery indicator is blinking yellow on my Huawei UPS?
If the battery indicator is blinking yellow, the buzzer buzzes for 1 second and then stops for 1 second, and the UPS is shutting down due to insufficient battery capacity, immediately save load data and power off critical loads. It may also be caused by incorrect parameter settings for the battery number or capacity, so ensure these parameters are set correctly.
Why is my Huawei UPS running on battery even when the mains is normal?
If the mains is normal but the AC input indicator is off, and your Huawei UPS runs in battery mode, first ensure that the mains switch is turned on. Also, check the input power cable connection to make sure it is securely connected.
