Operational Check of the Safety Valve that uses the Aircraft Batteries

TASK 32-31-00-710-013-A-01
Operational Check of the Safety Valve that uses the Aircraft Batteries

WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
  • THE FLIGHT CONTROLS
  • THE FLIGHT CONTROL SURFACES
  • THE LANDING GEAR AND THE RELATED DOORS
  • COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.
WARNING: MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.

1. Reason for the Job
Operational check of the safety valve 49GA that uses the aircraft batteries to make sure that the safety valve opens and closes correctly.
NOTE: This task is an alternative procedure to:
  • Operational check of the safety valve 49GA that uses the APU to energize the aircraft electrical circuits, (to make sure that the safety valve opens and closes correctly) (Ref. TASK 32-31-00-710-013-A)
    or
  • Operational check of the safety valve 49GA that uses the GND PWR contactor (3XG) override box, (to make sure that the safety valve opens and closes correctly) (Ref. TASK 32-31-00-710-013-A02).

   (2) On the panel 35VU, make sure that:
  • The GEN1, GEN2, APU GEN, EXT PWR and GALLEY pushbutton switches are pushed in.
Subtask 32-31-00-860-132-A
F. Aircraft Maintenance Configuration
   (1) Disconnect the isolation coupling of the PTU (Ref. AMM TASK 29-23-00-860-001).
   (2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
   (3) On panel 35VU, make sure that:
  • The GEN1, GEN2, APU GEN, EXT PWR and GALLEY pushbutton switches are released (out).
Subtask 32-31-00-860-127-A
G. Energize the Aircraft Electrical Circuits from the Batteries
WARNING: MAKE SURE THAT THE EXTERNAL POWER CONNECTOR IS NOT CONNECTED.
   (1) On the panel 35VU:
     (a) Make sure that the voltage of batteries 1 and 2 is more than 25.5 VDC.
     (b) Push (in) the BAT1 and BAT2 pushbutton switches.
   (2) On panel 25VU, on the section INT LT:
     (a) Set the DOME switch to the position DIM or BRT. Make sure that the dome lights come on.
     (b) Set the DOME switch to the OFF position. Make sure that the dome lights go off.
Subtask 32-31-00-480-069-A
H. Installation of the Test Equipment
   (1) Use the TIE WRAP(S) to install the 98F32304000000 TARGET-FALSE on:

A. Operational Check of the Safety Valve
WARNING: IF THE GROUND DOOR OPERATING-HANDLE MOVES AWAY FROM THE OPEN POSITION BUT THE RELATED DOOR(S) DOES(DO) NOT CLOSE, MOVE THE HANDLE BACK TO THE OPEN POSITION IMMEDIATELY. IF YOU DO NOT KEEP THE HANDLE IN THE OPEN POSITION ALL THE TIME, THE RELATED DOOR(S) CAN CLOSE SUDDENLY AND CAUSE INJURY TO PERSONS.
WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE LANDING GEAR DOORS ARE CLEAR.
   (1) Do the troubleshooting procedure related to the maintenance message shown.
NOTE: During this check, the ECAM shows the warning L/G SYS DISAGREE, which you can ignore.
ACTION
RESULT
1.On panel 20VU:
  • Make sure that the ADIRS is set to the OFF position.

WARNING: MAKE SURE THAT THE CONTROLS AGREE WITH THE POSITION OF THE ITEMS THEY OPERATE BEFORE YOU PRESSURIZE A HYDRAULIC SYSTEM. UNWANTED MOVEMENT OF HYDRAULICALLY OPERATED ITEMS CAN CAUSE SERIOUS INJURY AND/OR DAMAGE.
2.Use the GROUND POWER CART-HYDRAULIC to pressurize the Green hydraulic system (Ref. AMM TASK 29-10-00-863-001).
3.Try to move the applicable ground door-operating handle to the CLOSE position.
The related MLG door will not close.
NOTE: The ground door-operating handle can move because of the remaining Green hydraulic pressure, but the MLG door will not close. If the ground door-operating handle does move, set handle back to the open position.
4.Remove and discard the TIE WRAP(S).
5.Remove the 98F32304000000 TARGET-FALSE from:
  • Left MLG extension proximity-sensors 21GA
  • Right MLG extension proximity-sensors 20GA.
Safety valve 49GA is energized (valve open).
6.Move the ground door-operating handle to the CLOSE position.
The related MLG door closes.
   (2) Do a reset of LGCIU-1 (5GA1) as follows:
     (a) Open the circuit breakers that follow:
  • 1GA
  • 52GA.
     (b) Wait for a minimum of 15 seconds.
     (c) Close the circuit breakers that follow:
  • 1GA
  • 52GA.
     (d) Make sure that the ECAM does not show the warning L/G SYS DISAGREE.
