The slats WTB is the same as the flaps WTB. Refer to (Ref. 27-51-00) for data on the WTB.
7. Operation/Control and Indicating
________________________________
(Ref. Fig. 016)
A. Normal Operation
(1) System Requirements
For the normal operation of the slats:
-energize the aircraft electrical network
-close the circuit breakers 5CV, 7CV, 9CV and 11CV
-pressurize the Blue hydraulic system for the slat system 1 and the Green hydraulic system for the slat system 2.
NOTE : For safety, the circuit breakers 9CV and 11CV have a red guard
____ installed to prevent incorrect operation during flight. To open the circuit breakers it is necessary to remove the applicable red guard first.
(2) Manual Control
The slat and flap control lever controls the position of the slats. When the lever is moved to a new position, the slats move to the indicated slat angle.
NOTE : The slats will not move when the slat and flap control lever
____ moves from position 2 to 3 , or 3 to 2. As a function of the lever position, the flaps can move.

(3) Electrical Control
The CSU sends discrete signals to the slat channel of each SFCC. At the same time, the CSU sends discrete signals for the flap position to the flap channel. The switch pattern of the CSU changes when the control lever moves. This causes the SFCC to get different signals (Ref. Table 2). Each slat channel receives signals from two sets of the 5-track switches in the CSU. For a correct signal, each channel must receive the same detent pattern from the two sets of switches.

For a permitted out-of-detent pattern, each channel must receive the same out-of-detent pattern from the two sets of switches. If a different configuration occurs, it is a CSU failure.

(3) Electrical Control
The CSU sends discrete signals to the slat channel of each SFCC. At the same time, the CSU sends discrete signals for the flap position to the flap channel. The switch pattern of the CSU changes when the control lever moves. This causes the SFCC to get different signals (Ref. Table 2). Each slat channel receives signals from two sets of the 5-track switches in the CSU. For a correct signal, each channel must receive the same detent pattern from the two sets of switches.
For a permitted out-of-detent pattern, each channel must receive the same out-of-detent pattern from the two sets of switches.
A CSU failure is given as one of the two that follows:
-a CSU pattern being other than a valid selection or out-of-detent
-the CSU is seen to move directly from 0 to Full or from Full to 0 without going through positions 1, 2 or 3. This failure is called a CSU disadjust if it is confirmed by the other SFCC.
