The operation of the APU generator is through the APU GEN pushbutton switch, which has two stable positions: - when in OFF position, the pushbutton switch is released, and the white OFF legend is on. The generator is shut down (de-energized) and the line contactor is open, - when the pushbutton switch is pushed, the generator is energized, because its rotational speed is high enough. If the electrical parameters are correct, the GCU controls the line contactor closing: this causes the supply of the transfer circuit.

NOTE : On the ground, the generator line contactor closes only if the
____ ground power unit does not already supply the transfer network. For the power supply of the aircraft, the ground power unit is more important than the APU generator. (Ref. Fig. 007) When the FAULT legend comes on, there is a failure of the channel. At the same time:
-
the single chime operates,
-
the MASTER CAUT light comes on,
- on the upper ECAM display unit, an amber message is shown,
- on the lower ECAM display unit, the ELEC page is automatically
shown.
