C. Test
(1) On the ECAM control panel:
- push the DOOR key to get the DOOR/OXY page.
(2) Make sure that the SLIDE indication is not shown on the DOOR/OXY page when the L aft escape-slide handle is in the SLIDE ARMED position.
4. Fault Isolation
_______________
A. If the test confirms the fault:
- disconnect the connector of the handle proximity switch (7WN1)
- install the jumper wire between the pins B and C of the connector (7WN1-A) (Ref. ASM 52-73/01)
- do the test given in Para 3.B.

CES (1) If the test confirms the fault:
- replace the IND LT-SLIDE ARMED, AFT L DOOR (3WN1) (Ref. AMM TASK 52-73-21-000-002) and (Ref. AMM TASK 52-73-21-400-002).
(a) If the fault continues:
- replace the IND LT-SLIDE ARMED, L EMER EXIT (2WN1) (Ref. AMM TASK 52-73-21-000-003) and (Ref. AMM TASK 52-73-21-400-003).
(b) If the fault continues:
- replace the IND LT-SLIDE ARMED, FWD L DOOR (1WN1) (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001)
(c) If the fault continues:
- replace the RELAY-PWR SPLY SWITCHOVER (12WN) (Ref. ASM 52-73/01).
(d) If the fault continues:
- do a check for a ground signal at pin A/C of the proximity switch (7WN1) (Ref. ASM 52-73/01).
1 If there is a ground signal:
_
- do a check and repair the wiring from the connector (7WN1-A) to the indicator light (3WN1) pin A/B to pin H (Ref. ASM 52-73/01)
- do a check and repair the wiring from the indicator light (3WN1) to the SDAC-1(2) (1WV1(2)) pin K to pin AA (AD)/12B(12H) (Ref. ASM 52-73/01).
2 If there is no ground signal:
_
- repair the wiring from the connector (7WN1-A) pin A/C to the ground terminal (Ref. ASM 52-73/01).
(e) If the fault continues:
- do a check and repair the wiring from the indicator light (3WN1) to the indicator light (2WN1) pin A to pin B (Ref. ASM 52-73/01) and (Ref. ASM 52-73/01).
- do a check and repair the wiring from the indicator light (2WN1) to the indicator light (1WN2) pin A to pin B (Ref. ASM 52-73/01).
- do a check and repair the wiring from the indicator light (1WN1) to the relay (12WN) pin A to pin A/B2 (Ref. ASM 52-73/01).
- do a check and repair the wiring from the relay (12WN) to the circuit breaker (13WN) pin A/B3 to pin 2 (Ref. ASM 52-73/01).
- do a check and repair the wiring from the relay (12WN) to the circuit breaker (15WN) pin A/B1 to pin 2 (Ref. ASM 52-73/01). 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 艙門 DOORS(54)
