**ON A/C ALL
(a) The RAT and CSM/G are:
-automatically controlled by AC BUS 1 and AC BUS 2 loss and V > 100 kts,
- or manually by means of the EMER ELEC PWR/MAN ON guarded pushbutton switch on the EMER ELEC PWR section of the overhead panel 21VU.
When a failure of the AC BUS 1 and 2 occurs, simultaneously:
-
the RAT is automatically extended,
-
the emergency generator is automatically coupled to AC and DC ESS busbars,
-
the red FAULT legend comes on on RAT & EMER GEN annunciator
until the emergency generator is available. In all cases, the pilot has to press EMER ELEC PWR/MAN ON pushbutton switch in order to confirm the automatic logic. Red FAULT legend disappears if coupling is obtained.
(b) A test of the emergency generator can be initiated on the ground. The procedure is controlled by the EMER GEN TEST pushbutton switch located on the EMER ELEC PWR section of overhead panel 21VU. When EMER GEN TEST pushbutton switch is pressed and held:
-ELEC page is automatically displayed on the ECAM system (on ground only),
-the emergency generator is coupled to its network,
-DC ESS BUS SPLY and AC ESS BUS switching line contactors (4PC/3XC) open, isolating AC and DC essential busses,
- on the ECAM system: green lines between normal busbars and essential busbar disappear. The white EMER GEN, ESS TR and the green indications of the corresponding parameters appear, green lines between EMER GEN and AC ESS and DC ESS appear.
NOTE : The ELEC page must disappear when the EMER GEN TEST
____
pushbutton switch is released.
(c) A test of the emergency GCU can be initiated on the ground from the CFDS. The emergency GCU is a type 3 system:
i.e. it has neither an input bus nor an output bus, it is
connected to CFDIU by 2 discrete links.
The test procedure is described in
