Back-UPS XS 1300 behaving strangely after f02 short circuit on battery output
I accidentally caused a short on one of my UPS power outlets while trying to test the voltage with a multimeter. There was a loud noise & error f02, overload on battery output. For some reason, when I turn the system on now, “On line” flashes for about 5 seconds, then the battery symbol flashes for about 5 seconds. It didn’t do that before this happened - before it would simply turn on. Even if I don’t try to have it repaired, I want to know what may have happened to it internally when the short was created, and why this new behavior originated. Is it dangerous to keep using? TIA
When you first turn the UPS on the online icon, flash for a few seconds, then go solid, and the on-battery icon will flash for a few seconds while the UPS runs a self-test. When the self-test completes, the on-battery icon will go out, and the online icon should remain solid.
