Advanced Question Dragonfly probs

[Interceptor]

Hey Guys,I have been using the dragonfly for building my space station,but noticed when ever I start her up,with the right checklists,and procedures, I still get the warning lights DC V AC V,and FC LD.The only time I have seen them all off is when I use the included scenario Dragonfly powered up.I also use two in my scenario,and I can never get both powered up at the same time,only one.Are these bugs,and is there some type of work around for this.I have encountered both these instances in 2006P1,and,2010P1.Thanks,and,Happy holidays, I hope you can help.

I've checked and my Dragonflies work fine 2010P1, even multiple vessels.
I've noticed that the Dragonfly cannot be refueled for some reason (except for the RCS tank)
The only reason I can imagine (and simulate) is that that the tanks used for FCs are empty and You'll have to import a fresh Dragonfly from the scenario editor. I do hope that helps.
Oh, happy holidays to you too

I have imported a fresh Dragonfly from the scenario editor,and I still get the same thing.Thanks

Are you positive on the correct startup procedure? It took me 4 reads of the manual to figure out how to fire up a firefly correctly for the first time.

Oh yes, I have started it up dozens of times.I did read some earlier posts about much of the same problem,happening with others mainly in 2006P1,and I tried the suggested remedy,but with no luck.

I still get the warning lights DC V AC V,and FC LD.

Checking from the code:
DC V - either DC1 or DC2 voltage is outside (27,30) volts range
AC V - AC1 voltage is outsite of (35,38) volts
FC LD - FC1 load is outside of (20,200) amps (which could happen if you do not use FC1)

Use the gauges on the right panel to see what parameters are out of bounds. Alternativelly, save your scenario and look for the parameters under ELECTRICAL : format there is :
FCELL (status) (%clogged)
BATTERY (loading) (power left) (circuit breaker engaged)
DC (attached amps)
AC (attached amps)

FC1 is the first FCELL, DC1 and DC2 are the first DCs and AC1 is the first AC in the list.
If there is a bug in the loading/saving these are the parameters that will be messed up.

In a normally powered-up DF it should look something like:
FCELL 0 0.0367
FCELL 2 0.0000
BATTERY 0 5184000.0000 1
DC 122.1164
DC 0.0000
AC 30.0000
DC 0.0000
DC 14.0000

Yep, except the RCS tank all of the consumables in the DF are defined internally (check under the HYDRAULICS: in the scenario), each
tank has a line in the format:

TANK (opened) (valve position) (mass) (temperature)

There are no identifiers what tanks represent what, except for the order they are defined in the list:
first 3 TANKs - O2 tanks 1,2,3
next 3 TANKs - H2 tanks 1,2,3
next 1 TANK - H2O waste tank
next 2 TANKs - N2 pressure supply 1,2
next 2 TANKs - CO2 / LiOH collectors from the cabin
next 2 TANKs - O2/N2 representing the cabin
nexr 3 TANKs - O2/N2/CO2 representing the docking bay


You will kinda have to periodically save and re-edit these scenarios. As I remember some of the system are simply one-directional and there is no way to refill resources that will eventually come to an end: the fuel cells will run out of O2/H2 and will fill the H2O waste tank, the LiOH tank will run out and the cabin will start to fill with CO2, etc.

Sorry about the necro on this post. Just found the topic and became a bit nostalgic about the DF.
