4.8 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 Figure 4-7. 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.

Note ! If the RF14XU is mounted with the shaft pointing upwards, the

yellow and the blue lead to the potentiometer inside must be

interchanged (See Figure 4-9).

Electrical installation

The cables are carried through cable glands. If required, to avoid

any mechanical damage, the cables should be run in a conduit

between the rudder feedback unit and the junction unit or rudder

angle indicator. Electrical connection is shown in the cabling

diagram. The cable screen must be connected to the internal

ground terminal. Ref. Figure 4-8.
