A. If the fault symptom is identified by the CFDS message CHECK FIRE HANDLE 1 RESET GEN1 and the upper ECAM DU warning GEN1 FAULT:
- do a check of the status of the ENG1 FIRE pushbutton switch on the FIRE panel (1WD).
(1) If the pushbutton switch has not been pushed:
- do a check for intermittent +28VDC and repair the wiring between respectively: . the pin A/3A of the GCU1 and the pin A/C of the ENG/APU FIRE PNL (1WD) . the pin A/3A of the GCU1 and the pin A/B3 of the SENSOR-TDC AC1 (Ref. ASM 24-22/02).

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 panel 35VU:
- push, release and push again the GEN1 pushbutton switch (3XU1).
(3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).
(4) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).
(5) 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 GEN1 are shown and AC1 busbar is supplied by GEN1.

________
A. Put the aircraft back to its initial configuration.
(1) stop the engine 1 (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).
