2 Type 150/400 Autopilot System: Installation Guide
Step 1
*Note: The Raymarine GyroPlus yaw sensor measures the boat’s yaw (its rate of turn). The autopilot
system uses this information to enhance course keeping in adverse weather and sailing conditions (such
as sailing downwind in following seas). The Type 150G and Type 400G course computers contain a
built-in GyroPlus yaw sensor as standard. The Type 150 and Type 400 course computers do not contain
a built-in GyroPlus, but have the option of an external GyroPlus or dealer-fitted internal GyroPlus.
CAUTION:
Before installing the course computer and drive unit, check that
they are the correct voltage for your boat’s supply.
Compass
The compass is the direction sensor for the autopilot system. It
provides the course computer with precise information about the
boat’s heading.
Raymarine supplies a standard fluxgate compass for the autopilot
system.
Rudder position sensor
The rudder position sensor (or rudder reference transducer) provides
the course computer with the exact position of the boat’s rudder.
