B. Test of the Valve 13QMThe indicator shows that the valve isclosed.
The ENG 1 LP valve MOTOR 1 SUPPLY andCONTROL are energised.
(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.
