R (a) Do a check of the CSU and its wiring to the SFCC, which
R identified the out of detent condition (Ref. TASK 27-51-00-810-R 805).

May 01/04 CESR NOTE : When one system senses that the flap control lever is out
____ R of detent, but the other system senses a correct R condition, then the fault is usually in the CSU.
R (7) Make a record in the aircraft logbook to monitor the operation of the R slat system during the next flight.

B. Procedure
(1) If the ECAM warning SLAT SYS 1 (2) FAULT is shown, but there is no related CFDS message on the PFR, or in the SFCC 1 (2) Slat LLR, do step (2).
(2) Interchange SFCC1 with SFCC 2, (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001).
(a) Do a check of the upper ECAM DU for the ECAM Warning SLAT SYS 1(2) FAULT:
- if the fault moves to the opposite system, do step (3)
- if the fault stays in the intial system, do step (4).
(3) Replace the SFCC-1 (21CV) or SFCC-2 (22CV) identified in the ECAM Warning message shown in step (4)(a), (Ref. AMM TASK 27-51-34-000-001) and (Ref. AMM TASK 27-51-34-400-001):
(a) Do a check of the upper ECAM DU for the ECAM Warning SLAT SYS 1
(2) FAULT:
- if the message shows, do step (4)
- if the message does not show, no more maintenance is necessary.
(4) Remove the applicable slat fault relay 90CV or 92CV and use a multimeter to do a check at the base of the holder for a ground on pin Z and 28VDC on pin X:
- if there is a ground on pin Z and 28VDC on pin X, do step (5)
- if there is no ground on pin Z, do step (4)
- if there is no 28VDC on pin X, do step (6)
(5) Replace the applicable slat fault relay:
- for a SLAT SYS 1 FAULT message, replace RELAY-SLAT 1 FAULT (90CV)
- for a SLAT SYS 2 FAULT message, replace RELAY-SLAT 2 FAULT (92CV).
(a) Do a check of the upper ECAM DU for the ECAM Warning SLAT SYS 1
(2) FAULT:
- if the message is shows, do step (4)
- if the message does not show, no more maintenance work is necessary.

(6) Do a check and repair as necessary the aircraft wiring between the applicable C/B and connector AA pin 2J of the SFCC mounting tray:
- for relay 90CV, do the check from C/B 5CV and SFCC 1 (Ref. ASM 27-81/02)
- for relay 92CV, do the check from C/B 7CV and SFCC 2 (Ref. ASM 27-81/03).
(a) Do the Operational Test of the Slat System (Ref. AMM TASK 27-84-00-710-001) and make sure that the ECAM Warning SLAT SYS 1(2) FAULT does not show on the upper ECAM DU.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) Do the EIS Stop Procedure, if not done before (Ref. AMM TASK 31-60-00-860-002).
(2) Remove the ground support and maintenance equipment, the special and standard tools and all other items.
