 D. Main Transfer System (Ref. 28-26-00) The main transfer system controls the flow of fuel from the center (transfer) tank to the two wing tanks. The system uses the main fuel pump pressure (Ref. 28-21-00) to operate the jet pumps. The jet pumps move fuel by suction from the center (transfer) tank to the wing tanks. The operation of the main transfer system is usually automatic, but the crew can manually control the system when necessary.

 Operation/Control and Indicating

________________________________
 A. Control and Indication
 (1) Control Control of the fuel distribution system is usually automatic, but the crew can manually control the system when necessary. Most of the controls are in the cockpit. However, the controls for the refuel/defuel system are in the RH side of the belly fairing.
 **ON A/C 301-399,
 The cockpit overhead panel 40VU has the control switches for:
 -
the L TK PUMPS 1 and 2 (Ref. 28-21-00)

 -
the R TK PUMPS 1 and 2 (Ref. 28-21-00)

 -
the CTR TK L(R) XFR (Ref. 28-26-00)

 -
the MODE SEL AUTO (Ref. 28-26-00)

 -
the X FEED (crossfeed) system (Ref. 28-23-00).

 **ON A/C ALL
 The cockpit center-pedestal panel 115VU has the control switches for:
 -
ENG 1 MASTER 1

 -
ENG 2 MASTER 2 These switches open the related engine LP valve (Ref. 28-24-00) when they are set to ON.

 The cockpit overhead panel has the control switch APU MASTER SW. When set to ON this switch energizes the APU fuel pump system (Ref. 28-22-00) and opens the APU LP fuel shut off valve (Ref. 28-29-00).

 The cockpit overhead panel 20VU has the control switches for:
 -
ENG 1 FIRE

 -
ENG 2 FIRE

 -APU FIRE. when operated these switches put the related engine LP valve (Ref. 28-24-00) and/or the APU LP valve (Ref. 28-29-00) to the closed position.
 The Engine/Warning Display (E/WD) (Ref. 31-66-00) and the System
 Display (SD) (which together make the ECAM) give fuel distribution
 data to the crew. When specified failures occur:

 -a warning is given on the E/WD

 -the FUEL page shows on the SD.
 The crew can use the ECAM control panel to look at the FUEL page.
