INTERCELL TRANSFER - DESCRIPTION AND OPERATION
______________________________________________
1. General_______
The wing tanks have an inner and an outer cell that are divided by the sealed RIB 15 (Ref. 28-11-00). The two intercell transfer valves in each wing are near to the bottom of the RIB 15. Fuel in the wing tank outer cell is moved to the related inner cell by gravity when the related intercell transfer valve/s is/are open. The operation of the intercell transfer valves is controlled automatically by the Fuel Level Sensing Control Unit (FLSCU) (Ref. 28-46-00) and the Fuel Quantity Indicating Computer (FQIC) (Ref. 28-42-00). The Engine/Warning Display (E/WD) (Ref. 31-66-00) and the System Display (SD) (Ref. 31-67-00), (the Electronic Centralized Aircraft Monitoring (ECAM) display units), show intercell transfer system information to the crew. If specified failures occur:
-a warning is given on the EWD
-the FUEL page is shown on the SD.

3. System Description__________________ (Ref. Fig. 002) The intercell transfer system has:
-
two intercell transfer valves 27QM(29QM), 28QM(30QM)
-
two intercell-transfer-valve actuators 9QP(10QP), 11QP(12QP)
-
two intercell-transfer-valve drive shafts 70QM(72QM), 71QM(73QM). The intercell transfer valve 27QM(29QM) is on the outboard side of RIB 15 near to the bottom of the rib and the wing front spar. The intercell transfer valve 28QM(30QM) is on the inboard side of RIB 15 near to the bottom of the rib and the wing rear spar. The intercell-transfer-valve actuator 9QP(10QP) is on the front face of the wing front spar. The intercell-transfer-valve actuator 11QP(12QP) is on the rear face of the wing rear spar. Thus the actuators can be replaced without access to the related fuel tank. The actuators are connected to their related intercell transfer valve by the intercell-transfer-valve drive shaft 70QM(72QM) and 71QM(73QM). The actuators are attached to their related drive shaft by the V-band clamps 76QM(77QM) and 78QM(79QM). The intercell transfer system is controlled automatically by the FLSCU and the FQIC. When one of the two low level sensors 15QJ1/15QJ2 (Ref. 28-46-00) becomes dry, the FLSCU will send an open signal to the two actuators 9QP and 10QP. When one of the two low level sensors 16QJ1/16QJ2 (Ref. 28-46-00) becomes dry, the FLSCU will send an open signal to the two actuators 11QP and 12QP. When open the intercell transfer valves will not close until the next refuel operation. At the start of a refuel operation the intercell transfer valve actuators are sent a close signal by the FQIC. During a refuel using battery power, the intercell transfer valves are not energized and will not operate. If the intercell valves are in the open position, they will not close and it is not possible to refuel to maximum capacity. During a refuel using APU or External power the intercell transfer valves are energized and it is possible to refuel to maximum capacity. Intercell transfer valve position information is sent to the Display Management Computer (DMC) (Ref. 31-62-00) by the FQIC and the FLSCU. The DMC sends intercell tansfer system and valve position data to the ECAM. The intercell transfer valve position is shown on the SD FUEL page. If specified failures occur:
