(2) On the overhead panel 23VU, make sure that the FLT CTL/FAC 1 pushbutton switch is pushed (on this pushbutton switch, the FAULT and OFF legends are off).
(3) On the overhead panel 24VU, make sure that the FLT CTL/FAC 2 pushbutton switch is pushed (on this pushbutton switch, the FAULT and OFF legends are off).
(4) On the panel 110VU, make sure that the rudder trim is in the zero position.
(5) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(6) Pressurize the aircraft hydraulic systems
(Ref. AMM TASK 29-23-00-863-001) (Ref. AMM TASK 29-24-00-863-001) (Ref. AMM TASK 29-10-00-863-003).

Subtask 27-22-00-710-050-A ** ON A/C NOT FOR ALL

A. Operational Test of the Reset Function

NOTE: This test is for the system 1. For the system 2, use the indications between the parentheses.
You must do this test for the system 1 and the system 2.

ACTION	RESULT
1.On the FLT CTL panel 24VU (23VU):
release the FAC2 (FAC1) pushbutton switch.	On the FAC2 (FAC1) pushbutton switch: the OFF legend comes on and the FAULT legend stays off.
2.On the center pedestal, on the panel 110VU:
turn the RUD TRIM selector switch to the NOSE/L position and hold it in this position.	The rudder moves to the left. On the panel 110VU, on the RUD TRIM position indicator: the numbers change until the value L 20 deg plus or minus 1 comes into view. On the lower ECAM display unit: the pointer of the RUD indicator and the index that show the trim value move to the left. NOTE: In some cases, the pointer of the RUD indicator is not in line with the trim index.
3.Release the RUD TRIM selector switch.	There is no change.
4.Push and release the RUD TRIM/RESET pushbutton switch.	The rudder moves to the zero position and stays in this position. On the panel 110VU, on the RUD TRIM indicator: the numbers change until the value L 0 deg plus or minus 0.3 comes into view. On the lower ECAM display unit: the pointer of the RUD indicator and the index that show the trim value move to the center mark.
5.Turn the RUD TRIM selector switch in the NOSE/R position and hold it in this position.	The rudder moves to the right. On the panel 110VU, on the RUD TRIM indicator: the numbers change until the value R 20 deg plus or minus 1 comes into view. On the lower ECAM display unit: the pointer of the RUD indicator and the index that show the trim value move to the right. NOTE: In some cases, the pointer of the RUD indicator is not in line with the trim index.
6.Release the RUD TRIM selector switch.	There is no change.
7.Push and release the RUD TRIM/RESET pushbutton switch.	The rudder moves to the zero position and stays in this position. On the panel 110VU, on the RUD TRIM position indicator: the numbers change until the value R 0 deg plus or minus 0.3 comes into view. On the lower ECAM display unit: the pointer of the RUD indicator and the index that show the trim value move to the center mark.
8.On the FLT CTL panel 24VU (23VU):
Push the FAC2 (FAC1) pushbutton switch.	On this pushbutton switch: the OFF legend goes off and the FAULT legend stays off.
