April 17Apr 17 When going word for word over the Standby Power Test, some checklist items do not conform to what is seen on the panel; 1. With Battery OFF and STBY PWR ON, ESS BUS FAIL lights are ON and STBY BUS FAIL lights are OFF. (Reverse on checklist) 2. When checking STBY DC BUS, there is an Amp load across the bus (Checklist mentions 0 Amps) I believe the 2 items in point 1. are reversed. Looking at the panel electrical flow diagram, it is logical that the STBY bus is powered but not the ESS.. As for point 2., I don't know the system well enough, however in most cases when current is placed on a bus, there usually is some load associated as there will be items on that bus that are powered by default.
April 26Apr 26 I am seeing the exact things you describe. I also notice that the UNARM light doesn't illuminate next to the standby power toggle, but the emergency lighting one does. Edited April 26Apr 26 by Toddm
April 29Apr 29 Author I still need to read into the systems manual, but I'm inclined to believe that the checklist is wrong and the panel logic is right. Not sure though. (Solely the above report, not the UNARM light error introduced in 1.0.3. I haven't tested 1.0.4 yet)
