R NOTE : As the GEN 1 was set to OFF because of a true failure, the fault
____ R confirmation is not necessary.
R 4. Fault Isolation
_______________
R A. If the fault symptom is identified by the CFDS message IDG1 (E1-4000XU) R and the upper ECAM-DU warning GEN 1 FAULT:
R NOTE : This CFDS message comes into view when a generator under-frequency
____ R trip occurs because of a low oil pressure in the IDG. It usually R comes into view with the CFDS message IDG1 (E1-4000XU) LOW OIL R PRESSURE.
R - do a check of the Differential Pressure Indicator (DPI) of the IDG 1
R (Ref. AMM TASK 24-21-00-210-046).
R (1) If the DPI is extended:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040)
R and (Ref. AMM TASK 24-21-51-400-040).
R (2) If the DPI is not extended:
R - do a check of the IDG 1 oil level (Ref. AMM TASK 24-21-00-210-046).
R (a) If the oil level is 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).
R (b) If the oil level is low:
R - do a check of the IDG, the external oil-circuit tubing and the
R fuel/oil heat exchanger for oil leaks (Ref. AMM TASK 24-21-00-R 210-047).
R 1_ If there is leak:
R - repair the leak or replace the components as necessary
R - add oil (Ref. AMM TASK 12-13-24-612-041) and reconnect the
R IDG 1 (if disconnected).
R 2_ If there is no leak:
R - add oil (Ref. AMM TASK 12-13-24-612-041) and reconnect the
R IDG 1 (if disconnected)
R - do a dynamic disconnect test of the IDG 1 (Ref. AMM TASK 24-R 21-00-720-041).
R a_ If the oil pressure is correct:
R - stop the trouble shooting.
R b_ If the oil pressure is not correct:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-R 51-000-040) and (Ref. AMM TASK 24-21-51-400-040).

Aug 01/05 CESR B. Do this operational test to make sure that the system operates correctly. R (1) Aircraft Maintenance Configuration R (a) Energize the aircraft electrical circuits
R (Ref. AMM TASK 24-41-00-861-002).
R (b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only)
R (Ref. AMM TASK 31-60-00-860-001).
R (2) On the ELEC panel 35VU:
R - push, release and push again the GEN 1 pushbutton switch (3XU1).
R (3) Do the operational test of the GAPCU (Ref. AMM TASK 24-41-00-740-R 002).
R (4) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).
R (5) Do this test:
R -------------------------------------------------------------------------------
R ACTION RESULT
R -------------------------------------------------------------------------------R On the ECAM control panel: On the lower ECAM DU:
R - get the ELEC page. - the correct electrical parameters of
R the GEN 1 are shown and the AC1
R busbar is supplied by the GEN 1.
R 5. Close-up
________ R A. Put the aircraft back to its initial configuration. R (1) Stop the engine 1 (Ref. AMM TASK 71-00-00-710-028). R (2) Do the EIS stop procedure
R (Ref. AMM TASK 31-60-00-860-002).
R (3) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY R potentiometers to OFF. R (4) De-energize the aircraft electrical circuits
