Aug 01/05 CES A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002)
(2) Do the ADIRS start procedure (Ref. AMM TASK 34-10-00-860-002)
(3) On the EFIS control panel of the FCU:
- set the mode selector switches to ARC
(4) on the center pedestal, on the WEATHER RADAR CONTROL-UNIT (3SQ), start the weather radar system.
(5) On the CAPT EFIS switching panel 301VU:
- push the PFD/ND/XFR pushbutton switch until the CAPT ND comes into view on the CAPT PFD DU
- make sure that the PFD potentiometer (7WT1) is in the center position.
B. Make sure that this(these) circuit breaker(s) is(are) closed:

C. Test
Do the EIS system test (Ref. AMM TASK 31-60-00-740-004)
D. Put the aircraft back to its initial configuration.
(1) Do the ADIRS stop procedure (Ref. AMM TASK 34-10-00-860-005)
(2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002)
4. Fault Isolation
_______________
**ON A/C 051-099,
A. If the test gives the maintenance message WXR1(1SQ1)/WXR2(1SQ2)/DU PFD CAPT (2WT1)/DMC3(1WT3):
- replace the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-000-001) (Ref. AMM TASK 31-63-34-400-001)
(1) If the fault continues:
- replace the PFD-CAPT (2WT1) (Ref. AMM TASK 31-63-22-000-001) (Ref. AMM TASK 31-63-22-400-001)
(2) If the fault continues:
- replace the XCVR-WEATHER RADAR, 1 (1SQ1) and the XCVR-WEATHER RADAR, 2 (1SQ2) (Ref. AMM TASK 34-41-33-000-004) (Ref. AMM TASK 34-41-33-400-003) 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 指示和記錄系統 3(47)
