(3) On the ECAM control panel, push (in) the FUEL P/BSW.
(4) Make sure that the FUEL page shows on the ECAM lower display unit.
(5) Wait 60 seconds.
(6) Continue as follows:
NOTE : The FUEL page FQIs will show XXs in amber color, for 35
____ seconds, during the FQIC power up BITE test. A FQIS sensor fault must be sensed by the FQIC for 60 seconds before the applicable LRU identification is transmitted to the CFDS as unserviceable. The fault message is shown on the MCDU when set to SYSTEM REPORT/TEST (FUEL) and the FQIS STATUS page.
(a) Do the procedure to get access to the SYSTEM REPORT/TEST menu page (Ref. AMM TASK 31-32-00-860-001).
(b) When the SYSTEM REPORT/TEST menu page comes into view, push the line key adjacent to FUEL.
(c) When the FUEL menu page 1 comes into view, push the NEXT PAGE key on the MCDU keyboard to see the FUEL menu page 2.
NOTE : If a menu has more than one page (shown by the more to
____ come symbol > on the top line, right side of the MCDU display) each operation of the NEXT PAGE key on the MCDU keyboard will cause the next page to be shown. When the last page of any menu is shown, operation of the NEXT PAGE key will cause the first page to be shown.
(d) When the FUEL menu page 2 comes into view, push the line key adjacent to FQIS STATUS.
(7) Examine the FQIS STATUS page.

(8) If the message C CADENSICON 20QT:
(a) Is not shown, maintenance steps are not necessary.
(b) Is shown, go to Para. 4.A.
R R NOTE : You can get data from the:____ - Description and Operation (D and O) section of the Aircraft Maintenance Manual (AMM), the Fuel Quantity Indicating System (FQIS) (Ref. AMM 28-42-00 P.Block 001) - Trouble-shooting Manual (TSM) - Task Supporting Data (Ref. P. Block 301) - Aircraft Schematic Manual (ASM) (Ref. ASM 28-42/09).
R R R NOTE : You can get more trouble-shooting data from the____ CFDS(FUEL): - Input Parameters, pages 1 and 2 (Ref. AMM TASK 28-42-00-740-003) - Cadensicon Trouble Shooting Data, part of the Interrogation of the (SMITHS INDUSTRIES) FQIS Trouble Shooting Data (Ref. AMM TASK 28-42-00-740-007).
NOTE : OPTIONAL TESTING:____ If a DC Capacitance Fuel System Tester is available, measurements can be taken (of the capacitive section of the cadensicon sensor) before a decision is made to go into or close up a fuel tank. The Tester can be connected to the FQIC rack connector or the related tank wall connector. (Ref. P. Block 301 for the Tank Units DC Capacitance Values).
4. Fault Isolation_______________
**ON A/C 001-049, 051-061, 101-105, 201-203,
A. Procedure
(1) Temporarily replace the FQIC 3QT with a serviceable item (Ref. AMM TASK 28-42-34-000-001) and (Ref. AMM TASK 28-42-34-400-001).
NOTE : The step (1) has been included because it is important to make____ sure that the FQIC 3QT is serviceable before you start more steps.
(2) If the message C CADENSICON 20QT is not shown: - complete the installation of the FQIC (3QT) (Ref. AMM TASK 28-42-34-000-001) and (Ref. AMM TASK 28-42-34-400-001).

(3) If the message C CADENSICON 20QT is shown:
(a) Remove the temporarily installed FQIC 3QT and return it to stores (Ref. AMM TASK 28-42-34-000-001).
(b) Get access to the tank wall connector 7509VC in the right MLG bay (Ref. AMM TASK 32-12-00-010-001).
(c) Do a visual inspection and electrical tests of the aircraft wiring (Ref. AWM 28-42-14) and (Ref. AWM 28-42-15) between the FQIC rack connector 3QT-A and the tank wall connector 7509VC-A as follows:
1 Visual Inspection
_ Make sure that good lighting is available. Do a visual inspection and look for distortion (bent, pinched or stretched), damage (broken, chafed or cut), discoloration, overheating (burnt, melted or arcing), liquid contamination, loose electrical connection or incorrect assembly, of the items that follow:
- FQIC rack connector 3QT-A, pins 7H, 5H, 15G, 6F, 7F, 9F and 10F
- receptacle 212VC and connector 212VC-A
- receptacle 1973VC and connector 1973VC-A
- terminal block 7517VT and all of its connections
- receptacle 7575VC and connector 7575VC-A 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 FUEL 燃油2(119)
