3. Job Set-up
Subtask 27-96-00-860-060-A

A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) On the overhead panel 23VU, make sure that:

the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches are pushed (on these pushbutton switches, the FAULT and OFF legends are off).

(3) On the overhead panel 24VU, make sure that:

the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches are pushed (on these pushbutton switches, the FAULT and OFF legends are off).

(4) On the center pedestal, on the panel 8VU, make sure that:

the SWITCHING/ATT HDG, SWITCHING/AIR DATA, SWITCHING/EIS DMC and SWITCHING/ECAM/ND XFR selector switches are in the NORM position.

(5) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(6) On the center pedestal, on the ECAM control panel:

push the F/CTL key (on the lower ECAM display unit, the F/CTL page comes into view).

4. Procedure
Subtask 27-96-00-710-054-A

A. Do this test:

NOTE: During the test, ignore the MASTER CAUT and the single chime.

ACTION	RESULT
1.On the overhead panel 23VU: release the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches.	On the overhead panel 23VU: the OFF legends of the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches come on.
2.On the overhead panel 23VU: push the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches.	On the overhead panel 23VU: the OFF legends of the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches go off, the FAULT legends of the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches come on then go off.
3.On the overhead panel 24VU: release the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches.	On the overhead panel 24VU: the OFF legends of the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches come on.
4.On the overhead panel 24VU: push the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches.	On the overhead panel 24VU: the OFF legends of the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches go off, the FAULT legends of the FLT CTL/ELAC 2, FLT CTL/SEC 2 and FLT CTL/SEC 3 pushbutton switches come on then go off.

5. Close-up
Subtask 27-96-00-860-061-A

A. 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).
