__________________
A. Fault Analysis
(1) Do a check of the Post Flight Report (PFR):
- if the ECAM Warning message SLAT SYS 1 (2) FAULT is shown without a related CFDS message and the slats operate correctly, do the next step.
(2) Do the EIS Start Procedure (Ref. AMM TASK 31-60-00-860-001).
(3) At an MCDU, get access to the SYSTEM REPORT/TEST page (Ref. AMM TASK 31-32-00-860-006).
(a) Set F/CTL and get access to the SFCC1 and SFCC 2 menus.
(b) For each SFFC, set SLT LAST LEG REP and do a check for one or more of the messages that follow:
- SYSTEM STOP DUE TO LOW PRESSURE
- DC POWER INTERRUPT
- DC POWER BELOW 16V
- SINGLE MOTOR OPERATION
- LEVER OUT OF DETENT FOR MORE THAN 10 SEC
NOTE : These messages are shown in the Last Leg Report (LLR) to
____ help with trouble shooting when the ECAM Warning message SLAT SYS 1 (2) FAULT is shown because of a transient fault.
(c) From the check of the LLR:
- if one or more of the applicable messages is shown, do the fault isolation in Para. 4.A.
- if none of the applicable messages are shown, do the fault isolation procedure in Para. 4.B.

A. Procedure
(1) For the applicable message from the SFCC 1 (2) Slat LLR, do the related procedure step:
- for SYSTEM STOP DUE TO LOW PRESSURE, do step (2)
- for DC POWER INTERRUPT, do step (3)
- for DC POWER BELOW 16V, do step (4)
- for SINGLE MOTOR OPERATION, do step (5)
(2) SYSTEM STOP DUE TO LOW PRESSURE:
- if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because of a hydraulic low pressure problem (green or blue), no more maintenance work is necessary
- if there is no apparent hydraulic system problem, do the next step.
(a) Do the operational test of the slat system (Ref. AMM TASK 27-84-00-710-001).
- if a permanent fault is found go to Page Block 101 and do the applicable fault isolation procedure
- if there is no apparent fault with the slat operation, or the operation is intermittent, do the next step.
(b) Do the trouble shooting procedure for the applicable VALVE BLOCK SLAT 1 (25CV) or VALVE BLOCK SLAT 2 (26CV), (Ref. TASK 27-81-00-810-801).
NOTE : When the hydraulic motor operates, the spool of the
____ control valve is moved and flow occurs. This flow can push particles, in the hydraulic fluid, against the valve block filter and cause a blockage. If a blockage occurs, the flow decreases and the spool moves back. This movement of the spool is sensed by the related SFCC, which stops the applicable hydraulic motor. Flow then decreases and lets the particles become free from the filter. This removal of the blockage then increases the flow, which moves the spool. This movement of the spool is sensed by the related SFCC, which releases the applicable hydraulic motor. This causes the flow to increase to the condition where a blockage can occur again. This fault conditon can cause the slats to operate intermittently.
