NOTE : If the PACK 2 FAULT warning has appeared during engine start or
____ the flow control valve did not close during engine start (Ref. TASK 21-51-00-810-804).
(1) Do the pre-conditioning through the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(2) Do a check to make sure that the pack 2 inlet-pressure indication on the ECAM BLEED page is > 20 PSI.
(3) Do a check to make sure that the pack 2 flow control-valve symbol on the ECAM BLEED page is shown in the open poition.
(4) Do the operational test of the pack temperature-control system (Ref. AMM TASK 21-61-00-710-001).
NOTE : If a fault is detected, the PC gives a fault code for shop
____ maintenance in addition to the related CFDS message(s) (refer to TSM chapter 21-63-00, page block 301).

4. Fault Isolation
_______________
A. If the pack 2 inlet-pressure indication on the ECAM BLEED page is < 20 PSI:
- increase the pressure to > 25 PSI.

B. If the pack 2 flow control-valve symbol on the ECAM BLEED page is shown in the closed position:
- do a check of the pressure sense line between the FCV (8HB) and the SENSOR (11HM9) for contamination and clean it if necessary (Ref. AMM TASK 21-51-11-000-001), (Ref. AMM TASK 21-51-11-400-001), (Ref. AMM TASK 21-61-18-000-001) and (Ref. AMM TASK 21-61-18-400-001).
(1) If the fault continues:
- replace the VALVE-FLOW CTL (8HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).
(2) If the fault continues:
- replace the SENSOR-COMPRESSOR PNEUMATIC OVERHEAT (11HM9) (Ref. AMM TASK 21-61-18-000-001) and (Ref. AMM TASK 21-61-18-400-001).

- replace the FLOW CTL SYSTEM - PACK 2 (24HB) (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).

C. If the test confirms the fault:
- do a check that the resistance of the compressor temperature sensor (32HH) measured between connector A/A and A/B is in these limits (Ref. ASM 21-61/02):
Temp (Deg.C) OHMS ---------------------------
+ 10 103.9 +/- 0.5
+ 20 107.8 +/- 0.5
+ 30 111.7 +/- 0.5
+ 50 119.4 +/- 0.5
+ 70 127.1 +/- 0.5
+ 100 138.5 +/- 0.5
(1) If the resistance values are out of the specified limits:
- replace the SENSOR-COMPRESSOR TEMPERATURE (32HH) (Ref. AMM TASK 21-61-11-000-001) and (Ref. AMM TASK 21-61-11-400-001). 中國(guó)航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊(cè) AIR CONDITIONING 空調(diào)2(24)
