201-299, 301-399, Aug 01/05 CES (1) If the fault continues:
- replace the IDG oil cooler (Ref. AMM TASK 73-11-60-000-002) and (Ref. AMM TASK 73-11-60-400-002).
B. Do this operational test to make sure that the system operates correctly.
(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).
(2) On the ELEC panel 35VU:
- push, release and push again the GEN 2 pushbutton switch (3XU2).
(3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).
(4) Start the engine 2 (Ref. AMM TASK 71-00-00-710-003).
C. Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the ECAM control panel: On the lower ECAM display unit:
- get the ELEC page. - the correct electrical parameters of GEN 2 are shown and AC 2 busbar is supplied by GEN 2.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) Stop the engine 2 (Ref. AMM TASK 71-00-00-710-028).
(2) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY potentiometers to OFF.
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).

A. Test
Not applicable, you cannot confirm this fault on the ground.
4. Fault Isolation
_______________
A. If the fault symptom is identified by the CFDS message: CHECK IDG1 DISCONNECT CKT and by the warnings IDG1 OIL LO PR and IDG1 OIL OVHT on the upper ECAM display unit:
- replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).
(1) If the fault continues:
- replace the RELAY-IDG1 DISC CTL (3XT).
(2) If the fault continues:
- replace the RELAY-FUNCTION (7XT).
