A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Do the EIS start procedure (upper ECAM DU and lower ECAM DU only)
(Ref. AMM TASK 31-60-00-860-001).
(3) Start the engine (normal automatic start) (Ref. AMM TASK 71-00-00-860-823).
To do this test, you must start the engine 1 and energize the electrical circuit side 2 with an electrical Ground Power Unit (GPU) or with the APU (Ref. AMM TASK 24-41-00-861-002).
(4) On the HYD/FUEL panel 40VU, make sure that the L TK PUMPS/1 AND 2 and R TK PUMPS/1 AND 2 pushbutton switches are pushed.
(5) On the ECAM control panel, push the FUEL key.
(6) On the lower ECAM DU, make sure that the L wing tank pumps 1 and 2 and R wing tank pumps 1 and 2 operate correctly.

4. Procedure
Subtask 24-22-00-710-050-B

A. Operational test of the GLC-1

ACTION	RESULT
1.On the panel 121VU: open the circuit breaker 1QA.	On the panel 40VU: the FAULT legend of the L TK PUMPS/1 pushbutton switch comes on,
	On the lower ECAM display unit: on the FUEL page, the pump No. 1 of the left tank no longer operates.
2.On the EMER ELEC PWR panel 21VU: release the GEN 1 LINE pushbutton switch.	On the panel 21VU: the OFF legend of the GEN 1 LINE pushbutton switch comes on.
	On the panel 40VU: the FAULT legend of the L TK PUMPS/1 pushbutton switch goes off.
3.On the ECAM control panel: push the ELEC key.	On the lower ECAM display unit: the generator No. 1 no longer supplies the AC 1 busbar. This busbar is supplied from the other generator with the transfer circuit.
4.On the ECAM control panel: push the FUEL key.	On the lower ECAM display unit: pump No. 1 of the left tank operates, pump No. 1 of the right tank operates.
5.On the panel 121VU: close the circuit breaker 1QA, open the circuit breaker 2QA.	There is no change.
6.On the EMER ELEC PWR panel 21VU: push the GEN 1 LINE pushbutton switch.	On the panel 21VU: the OFF legend of the GEN 1 LINE pushbutton switch goes off.
