-
the pressure in the Green hydraulic system is 3.5 bar (51 psi) (Reservoir Pressure).
In the main landing gear compartment:
-
the PTU starts to operate because thepriority valve is open at 140 +0 -5bar (2030 +0 -72.5 psi).
On the lower ECAM DU:
-
the pressure in the Yellow hydraulic system is approximately 160 bar (2325 psi),
-
the pressure in the Green hydraulic system is no more than 14 bar (200 psi) less than the pressure in the Yellow hydraulic system.
In the main landing gear compartment:
-
the PTU stops when the priority valvecloses (between 144 bar and 127 bar(2088 psi and 1842 psi)).

11. On the hydraulic ground supply:
-pressurize the Blue hydraulic system to 135 bar (1960 psi).
NOTE : You must start at 135 bar
____ (1960 psi), because this is the min. pressure for the CSM/G to operate.
12. On the overhead panel 21VU:
-lift the guard, and press and hold the EMER GEN TEST pushbutton.
13. On the overhead panel 21VU:
-release the EMER GEN TEST pushbutton, and let the guard go back to its initial position.
14. On the hydraulic ground supply:
-slowly increase the supply pressure to the Blue hydraulic system to 160 bar (2325 psi).
15. On the overhead panel 21VU:
-lift the guard, and press and hold the EMER GEN TEST pushbutton.
16. On the hydraulic ground supply:
-slowly decrease the supply pressure to the Blue hydraulic system to 125 bar (1800 psi).
On the hydraulic ground supply:
-depressurize the Blue hydraulic system (Ref. TASK 29-10-00-864-003).
On the lower ECAM DU:
-
the ELEC page replaces the HYD page.
In the main landing gear compartment:
-
the Constant Speed Motor/Generator (CSM/G) does not operate, because the priority valve is closed at 130 +0 -3 bar (1885 +0 -43.5 psi).
In the main landing gear compartment:
-
the CSM/G starts to operate becausethe priority valve is open at 140 +0-5 bar (2030 +0 -72.5 psi).
In the main landing gear compartment:
-
the CSM/G stops when the priorityvalve closes (between 144 bar and 127bar (2088 psi and 1842 psi).
