__________
 Subtask 29-11-00-865-050
 A. Make sure that this(these) circuit breaker(s) is(are) closed:
 -------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------121VU HYDRAULIC/SOL VALVES/G/Y/PTU 1801GL N34 121VU HYDRAULIC/G HYD/PUMP ENG1/CTL 1701GK R35 121VU HYDRAULIC/G HYD/PUMP ENG1/MONG 1702GK R34

 Subtask 29-11-00-860-050
 B. Aircraft Maintenance Configuration
 (1)
 Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).

 (2)
 Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).

 (3)
 On the ECAM control panel on the center pedestal, press the HYD pushbutton. Make sure that the HYD page is shown on the ECAM lower Display Unit (DU)

 (4)
 Make sure that the ECAM does not show any of these conditions:

 -
low air pressure in the Green reservoir,

 -
low fluid level in the Green reservoir.

 

 (5)
 If necessary, pressurize the reservoir (Ref. TASK 29-14-00-614-002).

 (6)
 If necessary, add fluid to the reservoir (Ref. TASK 12-12-29-611-001) or (Ref. TASK 12-12-29-611-002).

 (7)
 On the overhead panel 40VU, press the PTU/AUTO P/BSW (the OFF light comes on).

 (8)
 On the overhead panel 40VU, make sure that the GREEN/ENG 1 PUMP P/BSW is set to on (FAULT and OFF lights are off).

 4. Procedure
_________ Subtask 29-11-00-710-050
 A. Operational Test of the Green Hydraulic System WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROL SURFACES
_______ ARE CLEAR BEFORE YOU PRESSURIZE/DEPRESSURIZE A HYDRAULIC SYSTEM.
 CAUTION : DO NOT START OR DRY MOTOR THE ENGINES WITH A HYDRAULIC GROUND
_______ POWER SUPPLY CONNECTED TO THE AIRCRAFT. IF YOU DO, YOU CAN CAUSE DAMAGE TO THE ENGINE PUMPS.

 -------------------------------------------------------------------------------
ACTION RESULT -------------------------------------------------------------------------------
1. Dry-motor the left (No. 1) engine
(Ref. TASK 71-00-00-710-001).

On the overhead panel 40VU: - press the GREEN/ENG 1 PUMP P/BSW. 
R 
On the overhead panel 40VU: - press the GREEN/ENG 1 PUMP P/BSW. 
R R R 

The left (No. 1) engine turns andcauses the engine-driven pump of the Green hydraulic system to turn.
 On the ECAM upper DU:
 -
the speed of the left (No. 1) engine is approximately 20 % N2.

 On the ECAM lower DU:

 -
the pressure in the Green hydraulic system is 3000 +100 -100 psi.

On the overhead panel 40VU:

-
the GREEN/ENG 1 PUMP OFF light comeson.

 On the ECAM lower DU:

 -
the vertical line between the EDP box and the system indication changes from green to amber.

 -
the engine pump symbol of the Green hydraulic system changes from green in-line to amber cross-line.

 -
the pressure in the Green hydraulic system decreases to 0 psi.

On the overhead panel 40VU:

-
the GREEN/ENG 1 PUMP OFF light goesoff.

 On the ECAM lower DU:

 -
the pressure in the Green hydraulic system increases to 3000 +100 -100 psi.

 -
the vertical line between the EDP box and the system indication changes from amber to green.

-
the engine pump symbol of the Green hydraulic system changes from amber cross-line to green in-line.

 

 -------------------------------------------------------------------------------
ACTION RESULT
 -------------------------------------------------------------------------------Stop the dry-motoring of the left On the ECAM lower DU: (No. 1) engine (Ref. TASK 71-00-- the pressure in the Green hydraulic 00-710-001). system decreases to 0 psi.
 5. Close-up
________
 Subtask 29-11-00-860-051
 A. Put the aircraft back to the serviceable condition.
 (1)
 On the overhead panel 40VU, press and release the PTU/AUTO P/BSW (the OFF light goes off).
