4. Procedure
Subtask 24-30-00-710-051-A

A. Do the CSM/G test with one normal TR failed:

ACTION	RESULT
1.On the panel 21VU, on the EMER ELEC PWR section: lift the safety cover, push and hold the EMER GEN TEST pushbutton switch.	On the lower ECAM display unit: the ELEC page comes into view automatically, the green lines between the AC1 and the AC ESS busbars and the DC1 and the DC ESS busbars go out of view, the EMER GEN and ESS TR indications are shown in white. The related parameters are shown in green, the green lines between the EMER GEN indication and the AC ESS busbar, the EMER GEN and the ESS TR indications, the ESS TR indication and the DC ESS busbar come into view, the SHED indication comes into view below the AC ESS and DC ESS busbars.
2.On the panel 21VU: release the EMER GEN TEST pushbutton switch.
3.On the ECAM control panel: get the ELEC page.	On the lower ECAM display unit: the normal configuration comes into view (the emergency AC generator stops).
4.On the panel 21VU: lower the safety cover.

5. Close-up
Subtask 24-30-00-710-052-A ** ON A/C NOT FOR ALL

A. Stop the engine (Ref. AMM TASK 71-00-00-710-028).

Subtask 24-30-00-710-052-B ** ON A/C NOT FOR ALL

A. Stop the engine (Ref. AMM TASK 71-00-00-710-018).

Subtask 24-30-00-860-051-A

B. Put the aircraft back to its initial configuration.
(1) If the test duration is more than 30 seconds, on the panel 22VU, the FAULT light of the EXTRACT pushbutton switch comes on.
If this occurs, release then push the EXTRACT pushbutton switch (the FAULT light goes off).
(2) Do the EIS stop procedure
(Ref. AMM TASK 31-60-00-860-002).
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002)

Subtask 24-30-00-410-050-A

C. Close Access
(1) Close the access doors 812 and 822.
(2) Remove the access platform(s).
