(4) Monitor the NOSE WHEEL ALIGNMENT TOOL display to make sure that the nose wheels stays at the zero position
NOTE : If the nose wheels haved moved, recenter the nose wheels to
____ the zero position with the BAR - STEERING NOSE WHEEL (98A09003000001)
Subtask 32-51-00-820-067
B. Set the NWS Zero position for the sensor 3GC
NOTE : The voltages U1 and U2 are in volts (3V approximately)
____
NOTE : The adjustment process is very sensitive
____
NOTE : Do not move the wheels manually
____
(1)
Make sure that the C/Bs 1GG and 2GG are closed
(2)
Open, safety and tag the C/Bs 3GC and 4GC
(3)
On the panel 402VU, put the A/SKID & N/W STRG switch in OFF position
(4)
Disconnect the connector from the RVDT 3GC
(5)
