(1) On the ENG/APU FIRE PANEL (1WD) located on the overhead panel 20VU, make sure that the ENG 1 FIRE PUSH pushbutton switch (P/BSW) is in the closed and guarded position.
(2) On the ECAM Control Panel 11VU, push (in) the FUEL P/BSW to get the FUEL system page on the ECAM lower display unit (DU).
(3) Make sure the ENG/MASTER 1 (3KC) switch (panel 115VU) is set to OFF.
(4) On the FUEL system page make sure the ENG 1 LP fuel valve symbol shows that the valve is closed (amber crossline).
(5) Make a note of the valve transit time for the following actions:
NOTE : The LP fuel valve symbol shows a 45 degree amber line while in
____
transit.
(a) Set the ENG/MASTER 1 (3KC) switch (panel 115VU) to ON, and immediately observe the ENG 1 LP fuel valve symbol on the FUEL system page.
(b) Make sure the ENG 1 LP fuel valve symbol changes to open (green in-line).
(6) Make a note of the valve transit time for the following actions:
NOTE : The LP fuel valve symbol shows a 45 degree amber line while in
____
transit.
(a) Set the ENG/MASTER 1 (3KC) switch (panel 115VU) to OFF, and immediately observe the ENG 1 LP fuel valve symbol on the FUEL system page.
