Block Diagram of full system
The AP46 head provides full control of the autopilot, indicating in
different modes heading, course to steer and rudder angle.
It requires a supply voltage of 12 volts DC.
The Rudder Feedback Unit (RFU) must be attached to the steering tiller
device in such a way that it can accurately measure the movement of the
ship’s rudder (see Rudder Feedback Installation diagram page 25). The
RFU must also be electrically connected to the AP46 Head unit.
Rudder actuator system: this system provides the physical movement to
the rudder responding to the direction control signals provided by AP46
system. A rudder actuator system comprises the following: -
Hydraulic Ram - controlled by either: -
1. Reversing motor and pump unit, connected into an existing
hydraulic steering system;
2. Solenoid valves connected into an existing power steering
system; or,
3. Solenoid valves connected to a continuous running motor and
pump unit.
