B. Aircraft Maintenance Configuration
WARNING : OBEY THE HYDRAULIC SAFETY PROCEDURES.
_______
(1)
Obey the hydraulic safety procedures (Ref. TASK 29-00-00-910-002).
(2)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(3)
On the overhead panel 50VU, make sure that the HYD /LEAK MEASUREMENT VALVES/B pushbutton switch (P/BSW) is set to on (OFF light is not on).
(4)
Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).
(5)
On the ECAM control panel on the center pedestal, press the HYD pushbutton. Make sure that the ECAM lower display unit (DU) shows the HYD page.
(6)
Make sure that the ECAM shows none of these conditions:
-
low air pressure in the reservoir of the Blue hydraulic system,
-
low fluid contents in the reservoir of the Blue hydraulic system.
(7)
If necessary, pressurize the reservoir (Ref. TASK 29-14-00-614-002).
(8)
If necessary, add fluid to the reservoir (Ref. TASK 12-12-29-611-001) or (Ref. TASK 12-12-29-611-002).
