(3)
Connect the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (F26792000-1) (2) between the connector (3) and the RVDT 3GC (1).
(4)
Connect an AC voltmeter (minimum range: 0-20V, accuracy: 1 mV,
frequency: 50-2000 Hz) to the SECONDARY VOLTAGE connections on the
SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST (2).
(5)
Open the CBs of the BSCU SYS2 (3GG and 4GG).
(6)
Make sure that the CBs of the BSCU SYS1 (1GG and 2GG) are closed.
(7)
On panel 402VU, put the A/SKID & N/W STRG switch in ON position.
(8)
With the captains handwheel, move the steering 75 degrees to the left then 75 degrees to the right then to the zero position.
(9)
Stage 1:
(a)
Make sure that the nose wheel steering handwheels and the rudder pedals are in neutral position. Do not operate them.
(b)
On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST
(2) set the selector switch to U1.
(c)
Record the voltage (U1)(in AC voltage).
(d)
On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST
(2) set the selector switch to U2.
(e)
Record the voltage (U2)(in AC voltage).
(f)
Calculate the algebraic value x:
x = (U1 - U2)
(10)
Get the rudder trim calculated value X obtained during Trouble Shooting procedure (Ref. TSM 32-51-00-810-823). On the panel 110VU, set the rudder trim switch to the same value.
(11)
Stage 2:
(a)
Make sure that the nose wheel steering handwheels and the rudder pedals are in neutral position. Do not operate them.
(b)
On the SENSOR-VOLTAGE TEST (F26792000) or SENSOR - VOLTAGE TEST
(2) set the selector switch to U1. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM LANDING GEAR 起落架9(3)
