Alternating On Line led and overload led
I have a back ups xs 1200 which recently developed a problem. After turning it on, The online led flashes green 8 times. Then a fan spins up. Then the overload led flashes red,then the online led flashes green,then the overload led flashes red,then the online led flashes green, then I hear a relay click. Then the cycle repeats.How do I fix this?
