6.2 Check rudder sensor operation (if fitted)
Note: This procedure is only required if you have fitted a rudder
position sensor to a wheel pilot system.
If you have fitted a rudder position sensor to a wheel pilot, before
commencing the initial sea trial you must make sure that it senses
rudder movement in the correct way and is aligned with the rudder:
1. Press the
-10
or
+10
key to move the helm to check that the rudder
bar display moves in the same direction as the sensor arm:
•
if the display moves in the opposite direction, swap the red
and green cables at the control unit (see page 84)
2. When you have done this, use the
-1
,
+1
,
-10
and
+10
keys to
move the helm to its center position.
3. Check the rudder bar display – the rudder angle should be within
±7° of center.
If necessary, bring the rudder angle to within ±7° of the center by
•
loosening the mounting bolts on the rudder position sensor
•
rotating the base of the sensor until the reported rudder angle
is as close to zero as possible
•
re-tightening the bolts
4. When the offset is less than ±7°, use the rudder alignment
(
ALIGN RUD
) setting in Dealer setup (see page 108) to accurately
align the display and helm.
Note: You cannot use the rudder alignment (
ALIGN RUD
) setting to
correct an offset of more than ±7°.
5. Calibrate the rudder limits using the rudder limit (
RUD LIMIT
)
setting in Dealer setup:
•
manually set the rudder to each end stop (port and starboard):
for each direction, use the rudder bar on the display to
determine the end-stop angle
•
access the rudder limit screen (
RUD LIMIT
)
•
set the autopilot rudder limit so that it is 5° less than the
smallest (port or starboard) mechanical end stop angle
