 (3) DC POWER INTERRUPT:
 - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because of a DC power interrupt, no more maintenance work is necessary

 - if there is no apparent DC power problem, do step (6).

 


 NOTE : The message DC POWER INTERRUPT is shown in the LLR when the DC
____ poweris less than 14VDC for more than 40 msec.
 (4) DC POWER BELOW 16V:
 - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because the DC power is less than 16.5 VDC, no more maintenance work is necessary

 - if there is no apparent DC power problem, do step (6).


 NOTE : The message DC POWER BELOW 16V is shown in the LLR when the DC
____ power is less than 16.5VDC, but more than 14VDC, for more than 20 msec.
 (5) SINGLE MOTOR OPERATION:

 - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because the slats operate momentarily on one motor only, no more maintenance work is necessary

 - if there is no apparent slat motor problem, do step (6).

 

 (6) Make a record in the aircraft logbook to monitor the operation of the slat system during the next flight.


R **ON A/C 301-399,

R A. Procedure

R (1) For the applicable message from the SFCC 1 (2) Slat LLR, do the
R related procedure step:
R - for SYSTEM STOP DUE TO LOW PRESSURE, do step (2)
R - for DC POWER INTERRUPT, do step (3)
R - for DC POWER BELOW 16V, do step (4)
R - for SINGLE MOTOR OPERATION, do step (5)
R - for LEVER OUT OF DETENT FOR MORE THAN 10 SEC, do step (6)

R (2) SYSTEM STOP DUE TO LOW PRESSURE:
R - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because of a
R hydraulic low pressure problem (green or blue), no more maintenance
R work is necessary
R - if there is no apparent hydraulic system problem, do the next step.

R (a) Do the operational test of the slat system (Ref. AMM TASK 27-84-R 00-710-001).
R - if a permanent fault is found go to Page Block 101 and do the
R applicable fault isolation procedure
R - if there is no apparent fault with the slat operation, or the
R operation is intermittent, do the next step.

R (b) Do the trouble shooting procedure for the applicable VALVE BLOCK
R SLAT 1 (25CV) or VALVE BLOCK SLAT 2 (26CV), (Ref. TASK 27-81-00-R 810-801).

 May 01/04 CESR NOTE : When the hydraulic motor operates, the spool of the


____ R control valve is moved and flow occurs. This flow can push R particles, in the hydraulic fluid, against the valve block R filter and cause a blockage. If a blockage occurs, the R flow decreases and the spool moves back. This movement of R the spool is sensed by the related SFCC, which stops the R applicable hydraulic motor. Flow then decreases and lets R the particles become free from the filter. This removal of R the blockage then increases the flow, which moves the R spool. This movement of the spool is sensed by the related R SFCC, which releases the applicable hydraulic motor. This R causes the flow to increase to the condition where a R blockage can occur again. This fault conditon can cause R the slats to operate intermittently.
R (3) DC POWER INTERRUPT:
R - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because of a DC
R power interrupt, no more maintenance work is necessary
R - if there is no apparent DC power problem, do step (7).

R NOTE : The message DC POWER INTERRUPT is shown in the LLR when the DC

____ R poweris less than 14VDC for more than 40 msec.
R (4) DC POWER BELOW 16V:
R - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because the DC
R power is less than 16.5 VDC, no more maintenance work is necessary
R - if there is no apparent DC power problem, do step (7).

R NOTE : The message DC POWER BELOW 16V is shown in the LLR when the DC

____ R power is less than 16.5VDC, but more than 14VDC, for more than R 20 msec.
R (5) SINGLE MOTOR OPERATION:
R - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because the slats
R operate momentarily on one motor only, no more maintenance work is
R necessary
R - if there is no apparent slat motor problem, do step (7)
R - if the message LEVER OUT OF DETENT FOR MORE THAN 10 SEC is also
R shown on the LLR, do the next step.

R (6) LEVER OUT OF DETENT FOR MORE THAN 10 SEC:
R - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because the flap
R control lever is sensed out of detent by each system, do step (7)
R - if the ECAM Warning SLAT SYS 1 (2) FAULT is shown because the flap
R control lever is sensed out of detent by one system only, do the
