B. During normal operation of the FLSS/FWC/DMC this is a configuration warning. If in the inner cell a pair of low level sensors that are AND gated together become dry indicating a fuel level of less than approximately 750kg (1650lb) for more than 30 seconds a low level warning is given. It is not a warning of a system/LRU failure or malfunction.

However, if the low level warning system is under suspicion:
(1) On the ECAM CONTROL PANEL push (in) the FUEL P/BSW.
(2) On the FUEL System Display (Lower ECAM) examine the wing tank FQIs.
(3) If the wing tank FQI(s) on the related side(s) show less than approximately 750kg (1650lb) when the L(R) or L + R WING TK LO LVL warning is given:
- no maintenance steps are necessary.
NOTE : Although this procedure has been written for when a permanent
____ LO LVL warning is given, the steps in the procedure are also applicable for when the wing tank FQIs show less than 750kg (1650lb) and the warning is not given.
