 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the panel 49VU:
 - open circuit breaker 1QP
 - wait ten seconds.
 2. On the panel 121VU:  - left wing fuel LO LEVEL warning is
 - open the circuit breaker 3QP  shown on the ECAM display unit
 - wait ten seconds.  - left wing transfer valve indicator on
 the ECAM display unit shows the
 transfer valve not fully open.
 3. On the panel 49VU:
 - open the circuit breaker 2QP
 - wait ten seconds.
 4. On the panel 121VU:  - right wing fuel LO LEVEL warning is
 - open the circuit breaker 4QP  shown on the ECAM display unit
 - wait ten seconds.  - right wing transfer valve indicator
 on the ECAM dispaly unit shows the
 transfer valve not fully open.
 5. On the panel 49VU:
 - close the circuit breaker 1QP.
 6. On panel 121VU:  - left wing transfer valve indicator on
 - close the circuit breaker 3QP.  the ECAM display unit shows the
 transfer valve fully open.
 7. On the panel 49VU:
 - close the circuit breaker 2QP.
 8. On the panel 121VU:  - right wing transfer valve indicator
 - close the circuit breaker 4QP.  on the ECAM display unit shows the
 transfer valve fully open.

 (2)
 Monitor the fuel quantity indicators on the ECAM display unit. Make sure that the quantity of fuel in the wing tank inner cells increases as fuel transfers from the outer cells.

 (3)
 Disconnect the electrical connector (1) from each forward transfer valve actuator 9QP(10QP) (2).

 (4)
 Put blanking caps on the disconnected electrical connectors.

 (5)
 Seal all the disconnected cables in a polythene bag.

 (6)
 Write an applicable entry in the aircraft technical logbook. NOTE : With the transfer valves electrically disconnected, the FLSS

____ BITE test will fail. The message XFR VALVE OPEN will be shown on the ECAM display unit.
