R The Green main system supplies the following consumers:
R - direct from the EDP (upstream of the priority valve)
R - the LH (No 1) engine thrust reverser.
R
R - from the HP manifold (through the LMS manifold):
R - the LH and RH spoiler 1,
R - the LH and RH spoiler 5,
R - the LH and RH aileron,
R - the LH and RH slat wing tip brake (WTB),
R - the RH flap WTB,
R - the LH elevator,
R - the rudder,
R - the trimmable horizontal stabilizer (THS),
R - the yaw damper.
R
R - from the PTU manifold (downstream of the priority valve):
R - the PTU
R - the RH slat power control unit (PCU) motor,
R - the LH flap PCU motor,
R - the nose landing gear and doors,
R - the main landing gear and doors.
R
R - from the PTU manifold (upstream of the priority valve),
R - the normal braking system.
R
R It is possible to supply all of the consumers from the ground supply
R connections.

The low pressure (LP) circuit returns the fluid from the consumers to the
reservoir. The case drains of the EDP and PTU, and the returns from the HP
manifold, are also connected to the LP circuit. The circuit has check valves
where applicable to control the flow of fluid. The check valves also protect
the main system if there is a leak in a subsystem. Some of the return lines
are connected together at the LP manifold (1003GM). Part of the LP circuit
is also used in the reservoir filling system (Ref. 29-16-00).
The LP fluid goes through the LP filter (1002GM) before it gets to the
reservoir. The filter has a filtration rating of 3 microns. If the filter
element clogs, a by-pass operates and unfiltered fluid goes to the
reservoir. A temperature sensor (1381GR) attached to the outlet of the LP

filter monitors the temperature of the return fluid. The temperature information is sent to the ECAM and warning systems (Ref. 29-33-00).
A filter (1084GM) is installed in the EDP case drain line to the LP system. It has a filtration rating of 15 microns. The system reservoir 1000GQ is installed in the main landing gear compartment. It holds a supply of fluid and also makes allowance for differences of the quantity of fluid in the system (due to different positions of jacks for example).
The reservoir is filled through the reservoir filling system (Ref. 29-16-00) which is operated from the ground service panel of the Green system. A reservoir drain valve is installed on the reservoir.
The reservoir is pressurized with air to 3.5 bar (50 psi) (to stop cavitation at the inlet of the EDP). The supply of air comes from the aircraft pneumatic system (Ref. 36-00-00). It is also possible to pressurize the reservoir from a ground supply. A depressurization valve is installed on the ground service panel of the Green system. A PRV and air pressure gage are installed on the reservoir.
A motorized valve 1046GK is installed in the suction line between the reservoir and the EDP. It operates when the engine FIRE pushbutton in the flight compartment is operated. It stops the supply of fluid to the EDP if there is a fire in the nacelle.
A compensated slide 1010GM is installed in the suction line between the reservoir and the EDP. It compensates for differences in pipe length, caused by changes in temperature, or normal movement of the wing in flight.
