Your DC EMER CONFIG was because you had lost DC1, DC2 and DC ESS busbars - thus no more DC ESS.
@Goldenrivett sorry mate, read it again I missed some details in your post. So the SHED's are lost on the old RAT thanks.
The point above though, why would you lose DC ESS surely even when you have lost the old RAT and the emerg gen the DC ESS is still powered directly from BAT 2?? It says it connects automatically on emerg gen loss. On the old rat that is.
@tom775257 yep, we still have a few of these as well! Nice little surprise ehh !!
It would be great to run the DC EMER CONFIG fault in the sim see what actually happens. As far as I can tell its not a hang up from the old rat system, but I'm not sure it would actually lose the DC ESS in real life ..
