2.7 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 2-5 on page 9. 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.

Max 600mm (23,5")

Figure 2-4 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 2-4) 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.
