AUTOPILOT
11.5 Rudder angle transmitter
The rudder angle transmitter should be mounted close to the rudder stock and driven
by its ball joint linkage according to the drawing shown below. The linkage should be
linear, such that 35° of rudder movement drives the arm 35°.
Small errors will not affect Autopilot operation but will cause inaccurate indication on the
rudder angle indicator. If possible, the linkage on the rudder transmitter should be
adjusted so that the digital rudder angle indicator on the Instrument display is consistent
with the rudder angle. The cable should be connected to Servo Unit terminals marked
"RFU" according to colours indicated.
The rudder transmitter unit must be securely mounted to a vertical surface and
connected by the adjusting tie rod linkage to the tiller, maintaining the geometry as
detailed in the diagram shown. The rudder transmitter arm must always swing in the
same plane as the tiller. Make sure all fasteners are well tightened and locked. For
maximum watertight integrity it is recommended that the unit is mounted with its rotary
shaft facing downward.
