B. Reset and Inialization.
(1) At the circuit breakers.
(a) Open the circuit breakers.
(b) Wait for 3 seconds and close the circuit breakers.
(c) Wait for 60 seconds
(2) Move the flaps.(Ref. AMM TASK 27-50-00-866-008) (Ref. AMM TASK 27-50-00-866-009)
(a) Examine the UPPER ECAM and the SD FLT/CTL page for the fault warnings and System status.
(b) Access the FLP ON GROUND FAULTS log and do a check of the ground log.
(c) If an UPPER ECAM warning, SD FLT/CTL status and a ground log fault message, is displayed do the Fault Isolation.
(d) If the UPPER ECAM, SD FLT/CTL status and the FLP ON GROUND FAULTS log are clear.No further maintenance actions are required.
4. Fault Isolation
_______________
A. Procedure.
(1) Set the MCDU to MENU MODE page 2 and access the submenu <FLP SYSTEM DATA.
(a) Press the line key 1R <PPU.
(b) Do a check of the PPU DATA (DEG) page. Refer to page block 301 table 2 for FPPU fault analysis.
R (c) If the no data "xxxx.x" is shown.
R (2) Swap SFCC 1 and SFCC 2, (Ref. AMM TASK 27-51-34-000-001) for (Ref. R AMM TASK 27-51-34-400-001) do Para. 2,3 and 4 only.
(a) Access the FLP ON GROUND FAULTS and do a check of the ground log.
(b) If the fault moves with SFCC 1(2).
(c) Install the SFCC 1 (2) in their initial locations.
(d) Replace the unserviceable SFCC-1 (21CV) (SFCC-2 (22CV)) Ref. Para.4.A.(2).
