(3)
Energize the ECAM system (Ref. TASK 31-60-00-860-001).
(4)
On the ECAM control panel, push (in) the FUEL pushbutton switch (P/BSW).
(5)
On the ECAM System Display (SD), make sure that the FUEL page is shown.
(6)
On the ECAM SD FUEL page, make sure that the intercell transfer valves show closed.

B. Operational Check of Individual Transfer Valves to Ensure Drive Shaft Rotates Valve to Open Position
NOTE : During the test the ECAM will show unwanted indications, which you
____
can ignore.
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. Open, safety and tag the circuit On the ECAM display unit (DU):
breaker 3QP. - the green right-wing transfer-valve indicator moves from the closed position to the open position
-
the green left-wing transfer-valve indicator moves from the closed position to the intermediate (amber) position
-
the right-wing outer-cell fuel content decreases and the right-wing inner-cell fuel content increases.
2. Remove the safety-clip and tag On the ECAM DU: and close the circuit breaker - the green right-wing transfer-valve 3QP. indicator moves from the open to the
closed position

ACTION RESULT -------------------------------------------------------------------------------
- the amber left-wing transfer-valve indicator moves from the intermediate
to the closed (green) position - the fuel movement to the right-wing inner-cell stops.
3. Open, safety and tag the circuit breaker 4QP. On the ECAM display unit (DU):- the green left-wing transfer-valve indicator moves from the closed
position to the open position - the green right-wing transfer-valve indicator moves from the closed
position to the intermediate (amber) position - the left-wing outer-cell fuel content decreases and the left-wing inner-cell fuel content increases.
4. Remove the safety-clip and tag and close the circuit breaker 4QP. On the ECAM DU:- the green left-wing transfer-valveindicator moves from the open to the closed position - the amber right-wing transfer-valve indicator moves from the intermediate
to the closed (green) position - the fuel movement to the left-wing inner-cell stops.
5. Open, safety and tag the circuit breaker 2QP. On the ECAM display unit (DU):- the green left-wing transfer-valve indicator moves from the closed
position to the open position - the green right-wing transfer-valve indicator moves from the closed
position to the intermediate (amber) position - the left-wing outer-cell fuel content decreases and the left-wing inner-cell fuel content increases.
6. Remove the safety-clip and tag and close the circuit breaker 2QP. On the ECAM DU:- the green left-wing transfer-valveindicator moves from the open to the closed position
