121VUEIS/SLIDES/ARM AND WARN/GND13WNP10
Subtask 52-21-00-710-052-A ** ON A/C NOT FOR ALL
B. Test
   (1) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only)
AMM 31-60-00-860-001
   (2) Remove and install the cover flap of the RH-FWD emergency-exit hatch (referred to as the hatch) AMM 25-23-47-000-001 and AMM 25-23-47-400-001.
NOTE: This makes sure the that target bracket of the cover flap is in its correct installation position.
   (3) On the DOOR/OXY page of the lower ECAM DU, look for the possible fault indications.
4. Fault Isolation
Subtask 52-21-00-810-052-A ** ON A/C NOT FOR ALL
A. When the cover flap is correctly installed and the DOOR/OXY page of the lower ECAM DU shows the symbol for the hatch and the message EMER EXIT in amber:
   (1) If the fault continues:
  • install the jumper wire between the:
    PROX SW-HANDLE FLAP, R FWD EMER EXIT [19WV2] connectors A/C and A/B ASM 315405.
     (a) If the message EMER EXIT goes off and the symbol for the hatch changes to green:
     (b) If the message EMER EXIT remains on in amber:
  • do a check for 28 VDC between the:
    PROX SW-HANDLE FLAP, R FWD EMER EXIT [19WV2] connectors A/A and A/C ASM 315405.
       1 If there is 28 VDC:
  • do a check and repair the wiring between:
    the PROX SW-HANDLE FLAP, R FWD EMER EXIT [19WV2] connector A/B and the IND LT-SLIDE ARMED, R EMER EXIT [2WN2] connector A/E ASM 315405.
       2 If there is no 28 VDC:
  • do a check and repair the wiring between the:
    PROX SW-HANDLE FLAP, R FWD EMER EXIT [19WV2] connector A/A and the IND LT-SLIDE ARMED, R EMER EXIT [2WN2] connector A/R ASM 315405.
    PROX SW-HANDLE FLAP, R FWD EMER EXIT [19WV2] connector A/C and ground ASM 315405.
   (2) If the fault continues:
     (a) If the fault continues:
  • do a check and repair the wiring between:
    the IND LT-SLIDE ARMED, R EMER EXIT [2WN2] connector A/G and the SDAC-1 [1WV1] or SDAC-2 [1WV2] connector AA/11C ASM 315405 .
       1 If the fault continues:
do the trouble shooting procedure of the SDAC-1 [1WV1] or SDAC-2 [1WV2] (Ref. TSM TASK 31-54-00-810-810) or (Ref. TSM TASK 31-54-00-810-803).
Subtask 52-21-00-710-056-A ** ON A/C NOT FOR ALL
B. Do a test as given in Para. 3.A. to make sure that the operation is correct.
5. Close-up
Subtask 52-21-00-860-052-A ** ON A/C NOT FOR ALL
A. De-energize the aircraft electrical circuits
AMM 24-41-00-862-002.
