(4)
 Connect the connector of the 28 VDC POWER SUPPLY TOOL (355M03200001) to the +28VDC connector of the aircraft.

 (5)
 Make sure that the solenoid 16CA is not energized.

 (6)
 Make sure that the travel ranges of the flight control surfaces are clear.

 C. Aircraft Maintenance Configuration
 (1)
 Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).

 (2)
 Pressurize the aircraft hydraulic systems (Ref. TASK 29-23-00-863-001) (Ref. TASK 29-24-00-863-001) (Ref. TASK 29-10-00-863-003).

 (3)
 On the overhead panel 23VU, make sure that the FLT CTL/FAC1 pushbutton switch is pushed (on this pushbutton switch, the FAULT and OFF legends are off).

 (4)
 On the overhead panel 24VU, make sure that the FLT CTL/FAC2 pushbutton switch is pushed (on this pushbutton switch, the FAULT and OFF legends are off).

 (5)
 On the center pedestal, on the panel 110VU, make sure that the RUD TRIM indicator shows 0.

 (6)
 Do the EIS start procedure (Ref. TASK 31-60-00-860-001).

 (7)
 On the center pedestal, on the ECAM control panel, push the F/CTL key (on the lower ECAM display unit, the F/CTL page comes into view).

 A. Do this test :

 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
R R  1. At the CAPT or F/O seat : - push the right pedal until it touches the mechanical stop (variable stop).  The rudder moves smoothly to the right.The force you must apply increasesslowly and continuously until the pedaltouches the mechanical stop. On the lower ECAM display unit, on the F/CTL page : - the pointer of the RUD indicator moves smoothly to the right.
 2. Slowly release the right pedal and push the left pedal until it touches the mechanical stop (variable stop).  The rudder moves smoothly to the left.The force you must apply to the rightpedal decreases slowly andcontinuously, then becomes zero. The force you must apply to the left pedal increases slowly and continuously until the pedal touches the mechanical
R R R  stop. On the lower ECAM display unit, on the F/CTL page : - the pointer of the RUD indicator moves smoothly from the right mark to the left.
 3. Slowly release the left pedal.  The rudder moves to the neutral position.

 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
The force you must apply to the left pedal decreases slowly and continuously, then becomes zero. On the lower ECAM display unit, on the F/CTL page : - the pointer of the RUD indicator moves to the neutral mark.
 4. Energize the solenoid 16CA with the 28 VDC POWER SUPPLY TOOL (355M03200001).  NOTE : The solenoid of the artificialfeel unit is energized.The second spring of the artificial feel unit is engaged.
 5. At the CAPT or F/O seat : - push the right pedal until it touches the mechanical stop (variable stop).  The rudder moves smoothly to the right.The force you must apply to the pedalsis much larger :- it is multiplied by three at the threshold.
 - it is multiplied by two at the limit of the travel.
