(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
B. Test
(1) On the ECAM control panel:
- push the DOOR key to get the DOOR/OXY page.
(2) Make sure that the L AVIONIC indication and the door symbol come into view amber.
4. Fault Isolation
_______________
A. If the test confirms the fault: R - do a check for 28VDC between pins A and D of door frame proximity R switch (23WV) (Ref. ASM 31-54/05).
R (1) If there is no 28VDC:
R - repair the wiring as necessary.
R (2) If there is 28VDC:
- disconnect the connector of the door frame proximity switch (23WV)
- install the jumper wire between the pins B and C of the door frame proximity switch (23WV) (Ref. ASM 31-54/05)
- do the test given in Para 3.B. R
R (a) If the test confirms the fault:
- do a check for a ground signal at pin C of the door frame proximity switch (23WV) (Ref. ASM 31-54/05).
R
R 1_ If there is no ground signal:
R - repair the wiring from the pin C of the door frame proximity
R switch (23WV) to the ground terminal.
R
R 2_ If there is a ground signal:
R - do a check and repair the wiring from the door frame
R proximity switch (23WV) to the SDAC-1(2) (1WV1(2)) pin B to
R pin AD/11E (Ref. ASM 31-54/05).
R
R (b) If the test does not confirm the fault:
- remove the jumper wire between the pins B and C of the door
frame proximity switch (23WV)
- connect the connector of the door frame proximity switch (23WV)
- adjust the door frame proximity switch (23WV) with the doors
checking tool (Ref. AMM TASK 52-71-00-820-008) or with the ECAM
system (Ref. AMM TASK 52-71-00-820-008).
