-
the blue indicator light comes on,

-
the indicator shows the fluid quantity of the reservoir of the Blue hydraulic system

The usual low-level warning system is inoperative
-the fluid quantity of the reservoir decreases.
When the fluid quantity indicator 1834GQ on the Green ground service panel, or the quantity indicator of the reservoir shows the fluid quantity 1.8 l (0.48 US gal): - on the ECAM lower DU:
* the color of the fluid quantity
indication changes from green to
amber

 - on the ECAM upper DU:
 * the message HYD-B RSVR LO LVL and related actions come on.
 -the single chime audio warning operates.
 - on the glareshield panels 130VU and 131VU:
 * the MASTER CAUT lights come on.
-the flow of fluid from the reservoirstops.

________
 Subtask 29-31-00-860-050
 A. Put the aircraft back to the serviceable condition.
 (1)
 Disconnect the hose and the adapter from the drain valve of the reservoir of the Blue hydraulic system.

 (2)
 Remove the container.

 (3)
 Stop the supply of air but do not disconnect the supply from the ground connector 1391GM.

 (4)
 On the ground service panel of the Green hydraulic system, set the reservoir-filling manual selector-valve to BLUE.

 (5)
 Use the hydraulic ground-service cart or the hand pump and fill the reservoir of the Blue hydraulic system to the same level as before the test.

 (6)
 On the ground service panel of the Green hydraulic system, set the reservoir selector valve to YELLOW.

 (7)
 Fill the reservoir of the Yellow hydraulic system to the same level as before the test.

 (8)
 On the ground service panel of the Green hydraulic system, set the
 reservoir-filling manual selector-valve to GREEN.

 (9)
 Fill the reservoir of the Green hydraulic system to the same level as before the test.

 (10)
 On the ground service panel of the Green hydraulic system, set the reservoir-filling manual selector-valve to NEUTRAL.

 (11)
 Make sure that all three reservoirs are pressurized to 50 psig. If necessary, use the air supply to fill them to the correct pressure.

 (12)
 Set the ground connector 1391GM to the CLOSE position and disconnect the FILL UNIT - AIR (98D29003501000).

 (13)
 Disconnect the hydraulic fluid supply as follows;

 (a) If a hydraulic ground-service cart was used: 1 Disconnect the hose from the fill connection 1007GM.
_
 2 Install the blanking cap on the fill connection.

_

 (b) If the hand pump 1009GM was used: 1 Remove the hand pump lever 3270GM from the hand pump.
_ 2 Retract the hand pump lever and put it in its position in the
_ ground service panel of the Yellow hydraulic system.
 3 Disconnect the flexible hose 1699GM from the reservoir fill
