3. Fault Confirmation__________________
A. Job Set-up
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
B. Test
Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel:
- push the ELEC key to get the ELEC page.
4. Fault Isolation
_______________
R A. If the test confirms the fault: On the upper ECAM display unit:
- these warnings come into view:ELEC AC BUS 1 FAULT ELEC AC ESS BUS FAULT ELEC DC ESS BUS FAULT
On the overhead panel, on panel 35VU:
- the FAULT legend of the AC ESS FEED pushbutton switch is on.
R - do a check of the feeders between the GLC1 (9XU1) and the busbar 1XP
R (Ref. AWM 24-51-05), (Ref. AWM 24-51-07) and (Ref. AWM 24-51-09).
R (1) If the feeders are not correct:
R - repair them.
R (2) If the feeders are correct:
R - do a check of the feeders between the GLC1 (9XU1) and the IDG1
R (4000XU) for a short to ground or a short circuit (Ref. AWM 24-22-
R 01).
R (a) If the feeders are not correct:
R - repair them.
R (b) If the feeders are correct:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-
R 040) and (Ref. AMM TASK 24-21-51-400-040).
B. Do this test to make sure that the system operates correctly:
-------------------------------------------------------------------------------
ACTION RESULT
-------------------------------------------------------------------------------
On the ECAM control panel: On the lower ECAM display unit:
- push the ELEC key to get the ELEC - the normal configuration comes into
page. view.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY potentiometers to OFF.
(2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
