AIR-DRIVEN GENERATOR (ADG) (CONT'D)
PWR TXFR OVERRIDE
With the ADG deployed, it may be possible to restore normal AC electrical power by resetting an engine-driven generator, or by using the APU generator. If AC electrical power is restored, the PWR TXFR OVERRIDE switch should be selected to reset the three transfer contactors and regain normal AC distribution. This returns the AC ESS BUS to AC BUS 1, and the 3B hydraulic pump to normal operation
