__________
Subtask 29-10-00-860-076
A. Aircraft Maintenance Configuration
R (1) Make sure that the isolation coupling 3701GM of the power transfer R unit (PTU) is not disconnected (Ref. TASK 29-23-00-860-002).
(2)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(3)
Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).
(4)
On the ECAM control panel, push the HYD key. Make sure that the HYD page comes into view on the ECAM lower display unit (DU).
(5)
Make sure that the ECAM system shows none of these conditions:
-
low air pressure in the reservoirs of the Green, Blue or Yellow hydraulic systems,
-
low fluid contents in the reservoirs of the Green, Blue or Yellow hydraulic systems.
(6)
If necessary, pressurize the reservoir(s) (Ref. TASK 29-14-00-614-002).
(7)
If necessary, add fluid to the reservoir(s) (Ref. TASK 12-12-29-611-001) or (Ref. TASK 12-12-29-611-002) .
(8)
On the overhead panel 40VU, push and release the PTU P/BSW. Make sure that the OFF light comes on.
(9)
Connect a hydraulic ground supply to the connections on the ground
R service panel of the Green hydraulic system (Ref. TASK 29-10-00-863-001).
