''gas control fault'' =L3GFLT shows at the alarm section.
L3GFLT (software relay) has to be energized only when L3GCVFLT or L3GRVFLT or L3IGVFLT any one of these three is energized. but the problem is none of these three relays is energized. but still L3GFLT/ gas control fault is showing '1' instead of '0'.
it is to say that at logic forcing section we see 'R' core is '1', 'S' core is '1', 'T' core is '0'. when i disable the R of S core the fault is gone. i am thinking that the problem is in R and S core control cards.
can anyone answer me that am i right or wrong? if right then can you tell me which card is responsible for this false fault? if wrong then what is the fault do you think?
my email address([email protected]), if possible send me the documents including which control cards control which thing..
thank you
