I finished what I started with spring loaded R1 switches.
For the AC part, the AC controllers ( 3 per AC bus) need to be closed now before actuating the inverter power or the inverter/ac bus relays.
The AC bus sensors are also implemented, in red.
Ac bus sensors examplesIf in off, F7 Alarm lights for AC overload and AC under/over voltage will be inhibited.
We have clearly an overload situation there, caused by a shortcut in AC 2 bus ( Amps out of limits in Fuel cell 2 and no more power in ac bus 2)
In monitor, F7 alarm AC lights will be illuminated ( normal mode)
AC overload and voltage appear.
Autotrip now.
Same than monitor for F7 alarms linked to AC , but it will disconnect automatically the faulty AC bus from its inverter, clearing all the other alarms and normalizing faster the situation.
We can see that just the AC voltage subsists, and no more consequences of overload elsewhere due to shortcut on the ac bus 2
Talkback associated, reading off.
If we put it to on again, shortcut will reappear, and an I/O reset on the keyboard will trip it again.
I mostly finished the SM part and fault messages, reading again what I have done and testing a lot to avoid any breakage before going ahead .
An example below of a "simple" FC failure and shutdown with the associated failures // indications
Spec 69 : Fuel cell display in red
FC reac // Reactant valves closed, no more O2/H2 going throught the cell
FC Pump // coolant pump off
FC Stack T // Temperature of the cell low
FC flow // no more O2/H2 flowing through it
FC amps // no output power from that cell
Spec 67: Electric display in purple
MAIN BUS V // No more power on Main Bus 1
AC Voltage // No me power on AC bus 1
Spec 88: Orbiter cooling display in yellow
Freon Loop // No more flow on Freon Loop 1 ( Pump inop due to ac bus 1 not powered)
Spec 66: Environment// Pressu and cooling fans in white
Av Bay Fan // Two avionic fans are off and Temp is rising in the bays
That helps to see clearly what we will have to do for trouble shooting through the pocket checklist
