A. If the pack 2 flow indicator on the ECAM BLEED page is stuck in the high position:
- replace the PRESSURE SENSOR (24HB1) (Ref. AMM TASK 21-51-11-000-001) (Ref. AMM TASK 21-51-11-400-001).
- replace the FLOW CONTROL SYSTEM (24HB) (Ref. AMM TASK 21-51-51-000-001) (Ref. AMM TASK 21-51-51-400-001).
(1) If the fault continues:

A. Bleed Air Supply Source from the HP Ground Connection
NOTE : The HP ground supply source must be able to give a pack inlet
____ pressure of 24 PSI minimum. If it can not do this then you must get the bleed air supply from the engines. The work steps which follow show the conditions necessary before you get the minimum pack-inlet pressure.
(1) Do the pre-conditioning through the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(2) On the AIR COND panel 30VU:
- push the HOT AIR pushbutton switch to the on position (the OFF legend goes off),
- turn the COCKPIT, FWD CABIN and the AFT CABIN temperature selectors to the HOT positions and,
- make sure that the PACK 1 and the PACK 2 pushbutton switches are in the on position (the OFF legends are off). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 AIR CONDITIONING 空调2(5)
