Type 150/150G/400/400G Course Computers Service Manual 83156-1
Type 150/400 Course Computers
Chapter 1: Introduction
This manual explains the service and maintenance procedures for the Raymarine Type 150,
150G, 400 and 400G autopilot Course Computers.
1.1. General
description
The Course Computer processes information from the sensors in the autopilot system (e.g.
rudder position and heading data) so it can steer the boat using the drive unit. The Course
Computer assembly consists of a plastic case, a printed circuit board (PCB) and a metal
heat-sink base. The PCB carries a microprocessor, electronic circuitry to control the drive
unit, a power amplifier for the drive motor and a connector block for all inputs and outputs.
1.2. Variants
There are 4 variants of the Course Computer:

Yes
The main visual differences between the four variants are:
•
version label on main cover (150, 150G, 400 or 400G)
•
Types 150G and 400G have a GyroPlus yaw sensor on the underside of PCB, with its
plug connected to socket on top left hand edge of PCB
•
Type 400/400G versions have:
•
40 A fuse for power supply (30 A for Type 150/150G)
•
extra terminals on left end of connector strip
•
expansion slot on left of PCB
•
additional capacitors and chokes on top right of PCB (and a choke on the
underside of PCB)
•
3 additional power devices and 2 additional FET clamps on right of PCB
