a ball piece
-
a sleeve.
The housing contains the actuating rod, the sleeve and the ball piece. The target is at the end of the actuating rod. The two sensors on the housing align with the targets on the actuating rod, with the flaps in their normal postion.
The actuating rod has a total travel of 18 mm (0.7086 in.) in each direction from the center position. The limit of independent movement between the flaps is 14.5 mm (0.5708 in.). The sensors send a target-far signal to the LGCIU if the target moves more than 15 mm (0.5905 in.) from the center position.

7. Operation/Control and Indicating
________________________________
(Ref. Fig. 021)
A. Normal Operation
(1) System Configuration
For normal operation of the flaps:
-energize the aircraft electrical network
-close the circuit breakers 6CV, 8CV, 10CV and 12CV
-pressurize the Green hydraulic system for flap system 1 and the Yellow hydraulic system for flap system 2.
NOTE : For safety, the circuit breakers 10CV and 12CV 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 flaps. When the slat and flap control lever is moved to a new position, the flaps move to the indicated flap angle.
NOTE : The flaps may move when the slat and flap lever moves from
____ position 0 to 1 or 1 to 0. Depending on the CAS from the ADIRU.

(3) Electrical Control
The CSU sends discrete signals to the flap channel of each SFCC. At the same time, the CSU sends discrete signals for the slat position to the slat 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 flap 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.

The CSU sends discrete signals to the flap channel of each SFCC. At the same time, the CSU sends discrete signals for the slat position to the slat channel. The switch pattern of the CSU changes when the control lever moves. This causes the SFCC to get different signals (Ref. Table 2).

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.
