C. Test
   (1) On the ECAM control panel:
  • push the DOOR key to get the DOOR/OXY page.
   (2) Make sure that the latch pin for the LH 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 52-21-00-810-060-A ** ON A/C NOT FOR ALL
A. If the test does not show the SLIDE indication on the DOOR/OXY page when the latch pin is in the slide armed position:
  • Open the handle flap from both LH emergency exits,
  • Look at the SLIDE ARMED indication between the emergency exits.
   (1) If the SLIDE ARMED indication is not on:
  • do a check of the SLIDE indication of the LH FWD passenger/crew door on the DOOR/OXY page with the escape slide handle in the armed position, to make sure that the power supply is correct.
     (a) If the SLIDE indication on the LH FWD passenger/crew door is on:
       1 If the fault continues:
       2 If the fault continues:
     (b) If the SLIDE indication on the LH FWD passenger/crew door is not on:
       1 If the fault continues:
  • do a check of the aircraft wiring between the circuit breakers 13WN and 15WN and the IND LT-SLIDE ARMED, L EMER EXIT [2WN1] ASM 527301.
     (c) Install the handle flap on both LH emergency exits.
   (2) If the SLIDE ARMED indication is on:
  • do check of the aircraft wiring between the SLIDE ARMED indicator light 2WN1 and the SDAC 1WV1(2) ASM 527301.
Subtask 52-21-00-710-066-A ** ON A/C NOT FOR ALL
B. Test
   (1) On the ECAM control panel:
  • push the DOOR key to get the DOOR/OXY page.
   (2) Make sure that the latch pins for the LH emergency exits are in the slide armed position.
   (3) Make sure that the SLIDE indication is shown on the DOOR/OXY page.
NOTE: If this occurs, the trouble shooting procedure is satisfactory.

C. If the test does not show the SLIDE indication on the DOOR/OXY page when the latch pin is in the slide armed position:
  • Open the handle flap from the LH emergency exit,
  • Look at the SLIDE ARMED indication near the emergency exit.
   (1) If the SLIDE ARMED indication is not on:
  • do a check of the SLIDE indication of the LH FWD passenger/crew door on the DOOR/OXY page with the escape slide handle in the armed position, to make sure that the power supply is correct.
     (a) If the SLIDE indication on the LH FWD passenger/crew door is on:
       1 If the fault continues:
     (b) If the SLIDE indication on the LH FWD passenger/crew door is not on:
       1 If the fault continues:
  • do a check of the aircraft wiring between the circuit breakers 13WN and 15WN and the IND LT-SLIDE ARMED, L EMER EXIT [2WN1] ASM 527301.
     (c) Install the handle flap on the LH emergency exit.
   (2) If the SLIDE ARMED indication is on:
  • do check of the aircraft wiring between the SLIDE ARMED indicator light 2WN1 and the SDAC 1WV1(2) ASM 527301.
Subtask 52-21-00-710-066-B ** ON A/C NOT FOR ALL
D. Test
   (1) On the ECAM control panel:
  • push the DOOR key to get the DOOR/OXY page.
   (2) Make sure that the latch pin for the LH emergency exit is in the slide armed position.
   (3) Make sure that the SLIDE indication is shown on the DOOR/OXY page.
NOTE: If this occurs, the trouble shooting procedure is satisfactory.
5. Close-up
Subtask 52-21-00-860-059-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
