SUA 1500i AVR Boost on permanently

Hi. Can anyone offer any advice please? I have an APC SUA1500i. Recently the AVR Boost orange LED came on and the transformer is buzzing. It remains permanently on all the time now with or without load. I have checked the input voltage and it is a solid 240v (UK) but the UPS is reporting 194v through Powerchute. I have tested it on another outlet with the same result. I have set the sensitivity to Low and have dropped to the lowest voltage range in the input voltage parameters in Powerchute. There are no warnings or errors in Powerchute. Should I swap out the 5 AVR relays on the main board or will it be something else? Thanks! Winston.

Hi Winston,

 

Please complete the brain dead reset process and report back what you see and observe once completed:

Please call out the serial number of the system as well. 👍

Hi! Thanks for your reply. I previously completed a brain dead reset on it and it performed a self test and came back up normally, albeit AVR Boost kicking in as soon as you connect it to an outlet. I then took it apart 😊. Is there anything in particular I need to look out for if I were to do try another BD reset? Serial number is AS0201110136.

 

Thanks! 👍🏽

Your system is very old more specifically it’s from 2002! 🫨

 

If possible move the unit to another home / building. Measure the input voltage to determine its 240 VAC. If so apply AC Mains to the system and report back if the system remains in AVR Mode.

 

As you stated earlier about changing the power quality and transfer voltages. Change both to the default settings and transfer voltage back to the default settings.

 

Complete the brain dead procedure again. Once complete power up the system without the battery cartridge attached what happens?!?
