3. Fault Confirmation
__________________
A. Job Set-up
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
B. Make sure that this(these) circuit breaker(s) is(are) closed:
-------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------
121VU EIS/SLIDES/ARM AND WARN/GND 13WN P10
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 R forward escape-slide handle is in the SLIDE ARMED position.
4. Fault Isolation
_______________
A. If the test confirms the fault:
- disconnect the connector A of the handle proximity switch (4WN2)
- install the jumper wire between the pins A/B, C of the handle proximity switch (4WN2) (Ref. ASM 52-73/01)
- do the test given in Para 3.B.
(1) If the test confirms the fault:
- replace the IND LT-SLIDE ARMED, FWD R DOOR (1WN2) (Ref. AMM TASK 52-73-21-000-002) and (Ref. AMM TASK 52-73-21-400-002).
(a) If the fault continues:
- replace the RELAY-PWR SPLY SWITCH OVER (12WN) (Ref. ASM 52-73/01).
(b) If the fault continues:
- do a check for a ground signal at pin A/C of the proximity switch (4WN2) (Ref. ASM 52-73/01).
1 If there is a ground signal:
_
- do a check and repair the wiring from the proximity switch (4WN2) to the indicator light (1WN2) pin A/B to pin H (Ref. ASM 52-73/01)

- do a check and repair the wiring from the indicator light (1WN2) to the SDAC - 1(2) (1WV1(2)) pin K to pin AA (AD)/12A,12G (Ref. ASM 52-73/01) and (Ref. ASM 52-73/01).
2 If there is no ground signal:
_
- repair the wiring from the proximity switch (4WN2) pin A/C to the ground terminal (Ref. ASM 52-73/01).
(c) If the fault continues:
- do a check and repair the wiring from the indicator light (1WN2) to the relay (12WN) pin A to pin A/A2 (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).
(2) If the test does not confirm the fault:
- remove the jumper wire between the pins A/B, C of the handle proximity switch (4WN2)
- connect the connector A of the handle proximity switch (4WN2)
- adjust the handle proximity switch (4WN2) with the door checking tool (Ref. AMM TASK 52-71-00-820-002) or with the ECAM system (Ref. AMM TASK 52-71-00-820-002).
(a) If the fault continues:
- replace the PROX SW-HANDLE, R FWD ESC SLIDE (4WN2) (Ref. AMM TASK 52-73-11-000-002) and (Ref. AMM TASK 52-73-11-400-002).
B. 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 shown on the DOOR/OXY page when the R. forward escape-slide handle is in the SLIDE ARMED position.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) On the ECAM control panel, set the LOWER DISPLAY and the UPPER DISPLAY potentiometers to OFF.
(2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
