(1) If all the circuit breakers are closed:
(a) Open the circuit breaker SDAC/1/SPLY (3WV). 1 If the ECAM warning C/B TRIPPED ON OVHD PNL goes out of view:
_ a Replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001)
_ and (Ref. AMM TASK 31-55-34-400-001).
b Close the circuit breaker SDAC/1/SPLY (3WV).
_ 2 If the ECAM warning C/B TRIPPED ON OVHD PNL stays in view, do
_ the actions given in Para. 4.B.(1)(b).
(b) Open the circuit breaker EIS/SDAC/2/SPLY (2WV). 1 If the ECAM warning C/B TRIPPED ON OVHD PNL goes out of view:
_ a Replace the SDAC-2 (1WV2) (Ref. AMM TASK 31-55-34-000-001)
_ and (Ref. AMM TASK 31-55-34-400-001).
b Close the circuit breaker EIS/SDAC/2/SPLY (2WV).
_ 2 If the ECAM warning C/B TRIPPED ON OVHD PNL stays in view:
_ a Do a check and repair the wiring (Ref. ASM 31-54/02):
_
- from SDAC1 (1WV1) connector AD/12A to the first terminal block.
- from SDAC2 (1WV2) connector AD/12A to the first terminal block.
b If the fault continues:
_
- do a check for a grounded circuit breaker.
- replace the grounded circuit breaker.
(2) If one circuit breaker or more are open: NOTE : On the ground, you must not close a tripped circuit breaker
____ without trouble shooting of the related system.
(a) Do an isolation check of the wiring between the circuit breaker and the related system (Ref. ASM 31-54/06):
1 If there is an isolation fault
_
- repair the wiring between the circuit breaker and the related system.
