-
the CTR TK L XFR (CTR TK R XFR) P/BSW.
If a fault occurs in the main transfer system:
-
the related FAULT annunciator will come on
-
the failure message FUEL L(R) XFR VALVE FAULT will be shown on ECAM.
The FAULT annunciator of the MODE SEL P/BSW will only come on in the AUTO configuration. If the FAULT annunciator of the MODE SEL P/BSW comes on, the P/BSW must be set to MAN. The crew then have manual control of the main transfer system.
The FAULT annunciator of the CTR TK L XFR (CTR TK R XFR) P/BSW can come on in the AUTO or the MAN configuration. If a FAULT annunciator of one of the CTR TK XFR P/BSWs comes on, that P/BSW must be set to OFF.
If one of the CTR TK XFR P/BSWs is set to OFF:

-fuel will transfer from the center (transfer) tank to one wing tank only
-the crew must crossfeed fuel (Ref. 28-23-00) from one wing tank to the other to keep the aerodynamic balance of the aircraft.
Gravity transfers fuel from the center (transfer) tank if the the two CTR TK XFR P/BSWs are set to OFF. Fuel only gravity transfers to the wing tanks when the level of fuel in the center (transfer) tank is greater than that in the wing tanks. When gravity transfer is in operation, approximately 2000 kg (4400 lb) of unusable fuel will remain in the center (transfer) tank.
