(a) 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).
(3) If the fault continues:
- do a check that the resistance of the compressor overheat sensor (35HH) measured between connector A/A and A/B is in these limits (Ref. ASM 21-61/02):

(5) If the pack 2 ram-air inlet-flap is closed:
- do a check for a ground signal at the pack controller 2 (27HH) connector AA/10A (Ref. ASM 21-61/01).
(a) If there is a ground signal:
- do a check of the RELAY-WHEEL 3 SPEED (24GG) and replace it if necessary (Ref. ASM 21-61/01).
(b) If the fault continues:
- do the test for the BSCU (10GG) as given in the AMM TASK 32-42-34-400-001 para. 5.A (Ref. AMM TASK 32-42-34-400-001).
1 If the test gives a different maintenance message, refer to
_
the Fault Symptom List.
(c) If the fault continues:
- replace the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
C. For a Pack Outlet Overheat Condition
(1) If there is no airflow at the pack 2 ram-air outlet:
- replace the MACHINE-AIR CYCLE (11HM1) (Ref. AMM TASK 21-52-21-000-001) and (Ref. AMM TASK 21-52-21-400-001).
(2) If the fault continues:
- do a check that the resistance of the pack outlet temperature sensor (34HH) 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
(a) If the resistance values are out of the specified limits:
- replace the SENSOR-PACK OUTLET TEMP (34HH) (Ref. AMM TASK 21-61-15-000-001) and (Ref. AMM TASK 21-61-15-400-001).
(3) If the fault continues:
(a) Remove the inspection panel from the pack 2 ram-air inlet plenum (11HM14),
(b) Do a check of the water injector nozzle for damage or wear:
- if the water injector nozzle is worn or damaged replace it (Ref. AMM TASK 21-52-00-960-001).

(c) Do a check of the main heat exchanger (11HM7) for contamination:
- if the main heat exchanger is clogged do the cleaning of the clogged main heat exchanger (11HM7) and the clogged primary heat exchanger (11HM6) (Ref. AMM TASK 21-52-00-100-001).
(d) Install the inspection panel in the pack 2 ram-air inlet plenum (11HM14).
(4) If the fault continues:
- do a check of the reheater (11HM3) for contamination (Ref. AMM TASK 21-52-00-780-001).
NOTE : This sub-paragraph (4) is only applicable to reheaters with
____ the P/N 755A0000-04 and previous. It is not applicable to reheaters with the P/NIs 755A0000-04 Amendment A or subsequent.
(a) If the reheater is clogged:
- do the cleaning of the clogged reheater (11HM3) (Ref. AMM TASK 21-52-00-100-002),
(5) If the fault continues:
- do the cleaning of the clogged condenser (11HM2) (Ref. AMM TASK 21-52-00-100-003),
(6) If the fault continues:
- replace the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(7) If the fault continues:
(a) Do a visual inspection of the plenum chamber of the air cycle machine (Ref. AMM TASK 21-52-00-200-001). 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(18)
