MASTER CAUTION ELEC BAT DISCHARGE
A fully charged battery supplies a MINIMUM of 30 minutes of standby power.
DC busses powered by the battery after loss of both generators.
- battery bus
- DC standby bus
- hot battery bus (always connected to the battery)
- switched hot battery bus (connected to the battery whenever the battery switch is ON)
(ISFD will continue for 150 minutes after loss of power to the battery bus)
MASTER CAUTION ELEC DRIVE
A generator drive malfunction occurs
if APU unavailable, plan to land at nearest available airport- only 1 source of pwr remains
MASTER CAUTION ELEC ELEC
A standby power or DC system fault occurs.
Will only illuminate on the ground. DO NOT TAKEOFF
LOSS OF BOTH ENGINE DRIVEN GENERATORS
Both engine driven generators are off.
Checklist leads to trying to get a generator back on line, or starting the APU (ONLY 1 APU START ATTEMPT IS RECOMMENDED SO WAIT UNTIL BELOW 250)
If no generators are able to power a transfer bus, a minimum of 30 minutes standby power from the battery remains
MASTER CAUTION ELEC SOURCE OFF
The transfer bus is not powered by the last selected source.
If reselecting the associated generator does not work, start the APU so the APU generator can supply the transfer bus.
If the APU is unable to to power the transfer bus
