Subtask 52-22-00-710-063-A ** ON A/C NOT FOR ALL
C. Test
   (1) On the ECAM control panel:
  • push the DOOR key to get the DOOR/OXY page.
   (2) Make sure that the slide control handle for the LH FWD emergency exit is in the slide armed position.
   (3) Make sure that the SLIDE indication is not shown on the DOOR/OXY page.
4. Fault Isolation
Subtask 52-22-00-810-059-A ** ON A/C NOT FOR ALL
A. If the test confirms the fault:
  • disconnect the connector A of the handle proximity switch (5WN1)
  • install the jumper wire at the connector A, between pins B and C of the handle proximity switch (5WN1) ASM 527301.
  • do the test given in Para 3.
   (1) If the test confirms the fault:
     (a) If the fault continues:
     (b) If the fault continues:
  • do a check for a ground signal at connector A, pin C of the proximity switch (5WN1) ASM 527301.
       1 If there is a ground signal:
  • do a check and repair the aircraft wiring from the proximity switch (5WN1) to the SDAC 1(2) ((1WV1 (2)) ASM 527301 and ASM 527301.
       2 If there is no ground signal:
  • repair the aircraft wiring from the proximity switch (5WN1) connector A, pin C to the ground terminal ASM 527301.
   (2) If the test does not confirm the fault:
  • remove the jumper wire of the connectors A between the pins B and C of the handle proximity switch (5WN1).
  • connect the connector A of the handle proximity switch (5WN1).
  • adjust the handle proximity switch (5WN1) with the door checking tool or with the ECAM system AMM 52-71-00-820-009.
     (a) If the fault continues:
Subtask 52-22-00-710-064-A ** ON A/C NOT FOR ALL
B. Do a test as given in Para. 3. to make sure that the operation is correct.
5. Close-up
Subtask 52-22-00-860-056-A ** ON A/C NOT FOR ALL
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
AMM 24-41-00-862-002.
