4.7 RF45X Rudder Feedback Unit
(For medium to large size vessels)
The RF45X Rudder Feedback Unit is normally installed with the
shaft pointing upwards. However, it can be mounted with the
shaft pointing downwards for increased convenience. The
deflection can then be inverted in the AP50 software or as
illustrated in Figure 4-5 on page 77. An “upside-down”
installation will make access to the unit more efficient as it can be
opened without moving it from the mounting base. To open the
unit, unscrew the two screws of the unit and remove the cover.
Be careful not to damage the wires when you replace the cover.

Figure 4-4 RF45X Rudder Feedback Unit Mounting
Use the enclosed template (Drawing 22011225) to drill the
required mounting holes. The unit is fastened to the mounting
base by the two Allen screws enclosed (other types of screws may
be used if it is to be fastened to another type of base, i.e. a
wooden base).
Make the parallelogram configuration of the transmission link
(see Figure 4-4) and temporarily fasten the link to the RF45X
shaft. The transmission rod can be shortened by cutting off a
piece using a hacksaw. Move the rudder manually hard over to
hard over and make sure the transmission link is moving freely in
both directions.
