B. Aircraft Maintenance Configuration
WARNING : OBEY THE HYDRAULIC SAFETY PROCEDURES.
_______
(1) Obey the hydraulic safety procedures (Ref. TASK 29-00-00-910-002).
NOTE : This procedure pressurizes the Green hydraulic system together
____ with the Yellow hydraulic system. If you do not want to pressurize the Green system, you must disconnect the PTU isolation coupling.
(2)
If required, disconnect the PTU isolation coupling (Ref. TASK 29-23-00-860-001).
(3)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(4)
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).
(5)
Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).
(6)
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.
(7)
Make sure that the ECAM shows none of these conditions:
-
Yellow reservoir low air pressure,
-
Yellow reservoir low fluid contents.
(8)
In addition, if you have not isolated the PTU, make sure that the ECAM does not show:
-
low air pressure in the reservoir of the Green hydraulic system,
-
low fluid contents in the reservoir of the Green hydraulic system.
(9)
If necessary, pressurize the reservoir(s) (Ref. TASK 29-14-00-614-002).
