C. Test
(1) On the ECAM control panel:
- push the DOOR key to get the DOOR/OXY page:
(2) Make sure that the OXY pressure indication is between 401 and 1499PSI on the DOOR/OXY page.
(3) Do an OXY high-pressure indication direct reading (Ref. AMM TASK 35-10-00-040-001).
4. Fault Isolation
_______________
A. If during the check of the pressure of the crew cylinder, the values is:
(1) The same as the value on the SD, on the DOOR/OXY page:
- replace the CYLINDER-OXYGEN STORAGE (5750HM) (Ref. AMM TASK 35-11-41-000-001) and (Ref. AMM TASK 35-11-41-400-001).
(2) Different from the value on the SD on the DOOR/OXY page:
- replace the XMTR/PRESS REG-OXY (4HT) (Ref. AMM TASK 35-13-15-000-001) (Ref. AMM TASK 35-13-15-400-001)
(a) If the fault continues:
- replace the CYLINDER-OXYGEN STORAGE (5750HM) (Ref. AMM TASK 35-11-41-000-001) and (Ref. AMM TASK 35-11-41-400-001).
B. Test
(1) Make sure that the OXY pressure indication is normal on the DOOR/OXY page:
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY potentiometers to OFF. (Ref. AMM TASK 31-60-00-860-002).
(2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
