5.6 RF14XU Rudder Feedback Unit
Mechanical mounting
Before installation check that the alignment mark on the mounting
plate agrees with the mark on the shaft. Bring the rudder to Midships
position. The feedback unit should be mounted on a plane surface
and secured by bolts through the three holes in the mounting plate. It
should be linked to the rudder in accordance with Fig. 5-18. It is
important that the linkage is linear, i.e. the A-a and D-d are pairs of
equal length. This will give a ratio 1:1 between the rudder angle and
that of the feedback unit shaft. Final adjustment is made by loosen
the fixing screws for the potentiometer, and carefully turn the
potentiometer for correct positioning.
