4. Procedure
Subtask 24-38-00-710-052-A

A. Operational Test of the BCL (without the CFDS)
(1) Do this test:

ACTION	RESULT
1.On the ECAM control panel: get the ELEC page.	On the lower ECAM display unit: the usual configuration comes into view, the BAT 1(2) indication is white, the white OFF indication is in view, the amber crosses are in view at the DC BAT busbar indication.
2.On the panel 35VU: push the BAT 1(2) pushbutton switch.	On the panel 35VU: the OFF legend of the BAT 1(2) pushbutton switch goes off.
	On the lower ECAM display unit: the green DC BAT busbar indication comes into view, the green line between the BAT 1(2) indication and the DC BAT busbar indication comes into view. The arrow points to the BAT 1(2) indication, the related parameter indications (voltage and current) come into view in green.
	After approximately 12 seconds, the green line between the BAT 1(2) indication and the DC BAT busbar indication: goes out of view if the battery charge is correct and it is not necessary to charge the battery. stays in view if it is necessary to charge the battery.
3.On the panel 35VU: release the BAT 1(2) pushbutton switch.	On the panel 35VU: the OFF legend of the BAT 1(2) pushbutton switch comes on.
	On the lower ECAM display unit: the green line between the BAT 1(2) indication and the DC BAT busbar indication goes out of view (if it was in view).
	NOTE: If the BAT 1 and BAT 2 pushbutton switches are released simultaneously: the white OFF indication comes into view, the amber crosses come into view at the DC BAT busbar indication.

(2) If necessary, charge the battery (Ref. AMM TASK 24-30-00-040-001).

5. Close-up
Subtask 24-38-00-410-052-A

A. Close Access
(1) Close the access panel of the BATTERY power center 105VU.
(2) Close the access door 822.
(3) Remove the access platform(s).

Subtask 24-38-00-860-053-A

B. Put the aircraft back to its initial configuration.
(1) Do the EIS stop procedure
(Ref. AMM TASK 31-60-00-860-002).
(2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
