A. Test of the Valve 12QM
(1)
In the test that follows, on each operation of the LP valve:
-
make sure that the see/feel indicator operates smoothly, from the valve open (valve closed) position to the valve closed (valve open) position
-
make sure that the see/feel indicator marks are accurately aligned in the valve open position
-
make sure that the see/feel indicator marks are at 90 degrees to each other in the valve closed position.
(2)
For the valve 12QM, do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1.
On the panel 121VU:
- open, safety and tag the circuit breaker 3QG.
2.
On the ECAM CP:
-push (in) the FUEL P/BSW.
3.
On the LP valve actuator 9QG:
-look at the position of the mechanical see/feel indicator.
4.
On the panel 115VU:
-put the ENG/MASTER 1 switch to the ON position.
5.
On the LP valve actuator 9QG:
The ENG 1 LP valve MOTOR 2 SUPPLY andCONTROL are isolated.
On the ECAM lower DU:
-
the FUEL system page shows
-
the LEFT LP valve indication shows the valve closed (amber cross-line).
The indicator shows that the valve isclosed.
On the ECAM lower DU:
-the LEFT LP valve indication showsthe valve open (green in-line).
