3. Fault Confirmation
__________________
A. During normal operation of the ECAM, the FUEL - AUTO FEED FAULT is a configuration warning.
NOTE : This ECAM warning is only given in certain flight phases, and is
____
controlled by the FWC.
This warning function is activated simultaneously with the FAULT legend on the P/BSW-CTR TK/MODE SEL/AUTO (48QA).
NOTE : The FAULT is only given with the P/BSW in the AUTO (in) position.
____
These indications are given because the fuel load distribution is not correct or the fuel has not been used in the correct sequence.
The warnings will be activated if for 60 seconds the fuel distribution (for any reason) is as follows:
- the left wing tank, less than 5000 kg (11000 lb) AND the center tank, more than 250 kg (550 lb)
- the right wing tank, less than 5000 kg (11000 lb) AND the center tank, more than 250 kg (550 lb).
The warnings will be reset immediately when the fuel distribution
conditions no longer exist.
The source of the comparison logic which activates and resets this
warning is contained in the FQIC (3QT).
The FQIC warning/FAULT logic output is inhibited during automatic
pressure refuel.
The FQIC warning/FAULT logic output is transmitted on:
- two (2) ARINC bus lines to the FWC (ECAM)
- two (2) discrete signal lines OR gated together to the P/BSW-CTR TK/MODE SEL/AUTO (48QA), FAULT legend.
(1) Examine the aircraft log/investigate the fuel configuration at the time of the original/repeat failure. Compare this with the fuel configuration given before.

(2) Do the BITE test of the FLSS (Ref. AMM TASK 28-46-00-740-001).
(3) If failures are detected examine the FLSS STATUS page for any of the messages that follow:
- FLSCU1(2) 7QJ(9QJ)
- C LO LEVEL SENSOR 21QJ
- C LO LEVEL SENSOR 22QJ
- L(R) FULL LEVEL SENSOR 23QJ1(2)
- L(R) UNDERFULL LEVEL SENSOR 24QJ1(2)
- L(R) UNDERFULL LEVEL SENSOR 25QJ1(2)
- L(R) UNDERFULL LEVEL SENSOR 26QJ1(2)
- L(R) FULL LEVEL SENSOR 27QJ1(2).
(4) If none of the messages identified in Step (3) are shown:
- go to Step (6).
