B. Test
(1) Do the BITE test of the FLSS (Ref. AMM TASK 28-46-00-740-001).
NOTE : The FLSS high level sensor channels are normally only supplied
____ with 28VDC during their refuel system function. They can only be tested when the fuel system is in the configuration that follows:
- the aircraft is on the ground
- the refuel panel door is open and/or the PWR P/BSW (23QU), at the cockpit REFUEL panel (51VU), is set to ON.
(2) Examine the FLSS STATUS page on the MCDU.
(3) If a fault message(s) for one or more of the other FLSS sensors and/or the FLSCU-1 (7QJ) is shown:
- do (Ref. TASK 28-46-00-810-818).
(4) If the message 284615 C HI LEVEL SENSOR 20QJ:
- is shown, do Para. 4.A.
- is not shown, no work steps are necessary.
NOTE : You can get more data from the:
____
- Description and Operation (D and O) section of the Aircraft Maintenance Manual (AMM) Chap. 28-46-00, the Fuel Level Sensing System (FLSS)

- Aircraft Schematic Manual (ASM) (Ref. ASM 28-46/01). You can get more Trouble-shooting data from the CFDS(FUEL):
- Input Parameters Page 3 (Ref. AMM TASK 28-42-00-740-003) used with the Fuel Level Sensors Operating (Changeover) Values (Ref. P. Block 301)
- FLSCU Trouble-shooting Data (Ref. P. Block 301).
NOTE : OPTIONAL TESTING:
____ Where a PSDA320-2 Fuel Level Sensing Test Set is available measurements can be taken before a decision is made to go into or close up a fuel tank. The Test Set lets the tank mounted components and tank wiring be tested from the tank wall connectors.
