A. Procedure.
NOTE : You can get more data from the:
____
- Aircraft Maintenance Manual (AMM) Chapters 26-12-00, 26-21-00, 28-24-00, and 76-12-00 - Description and Operation (D and O)
- Trouble Shooting Manual (TSM), Task Supporting Data, (Ref. P. Block 301)
- Aircraft Schematic Manual (ASM) (Ref. ASM 26-21/02), (Ref. ASM 28-24/01), and (Ref. ASM 76-12/01).
(1) On the ENG/APU FIRE PANEL (1WD) located on the overhead panel 20VU, make sure that the ENG 1 FIRE PUSH pushbutton switch (P/BSW) is in the closed and guarded position.
(2) On the ECAM Control Panel 11VU, push (in) the FUEL P/BSW to get the FUEL system page on the ECAM lower display unit (DU).
(3) Set the ENG/MASTER 1 (3KC) switch (panel 115VU) to OFF.
(4) Examine the ENG 1 LP fuel valve symbol on the FUEL system page.
(5) Examine the see/feel indicator on the ACTUATOR-LP FUEL VALVE, ENG 1 (9QG). (Ref. P. Block 301).
(6) If the FUEL page shows the ENG 1 LP fuel valve symbol as an amber cross line, and the see/feel indicator on the ENG 1 LP fuel valve shows that the valve is closed:
- maintenance steps are not necessary.

4. Fault Isolation
_______________
A. If the FUEL page shows the ENG 1 LP fuel valve symbol as amber, in line, and the see/feel indicator on the ENG 1 LP fuel valve shows that the valve is open. (Ref. P. Block 301).
(1) Examine for obvious signs of damage the items that follow:
- the actuator supply cables and end connectors
- the actuator electrical recepticals
- the cable looms next to the actuators.
NOTE : Left Wing Wire Routing (Ref. AWM 94-05-02).
____
(2) Repair/replace all the unserviceable wiring and connectors.
(3) Do the test given in Para. 3.A.
(4) Disconnect the electrical supply cable connector 9QG-A from the ACTUATOR-LP FUEL VALVE, ENG 1 (9QG). 中國航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 FUEL 燃油2(35)
