Hi Minh,

If the 1 represents the top LED in the battery bar graph then the 10000 bar graph and fault X LED combination indicates an over temperature event. If the batteries in the SURT2000XLI are from 2001/2002 then chances are these may be causing the event due to old / defective batteries. On the other hand this may also indicate a hardware issue for example with the UPS temperature probe. The easiest way to test if the UPS electronics are not affected is to cross test the system with a known good RBC31.
