CHAPTER 1 SYSTEM DESCRIPTION
Your CM400N is an advanced autopilot, resulting from many years of
design and engineering experience at Coursemaster. The autopilot is simple to
use and we have also tried to keep this manual simple and staightforward. But
to obtain the best results, you should know how the pilot and your vessel will
work together. So please take some time to read this and please contact
Coursemaster or one of our agents if you have any questions.
The CM400N adds a number of features to its predecessor - the CM400.
These include a heavy-duty Junction Box, a wider range of input voltages, dual
Controller and Remote Helm capability, a remote alarm and, most importantly a
built-in interface to NMEA0183 navigation equipment.
1.1 SYSTEM COMPONENTS
The basic autopilot comprises:
CM641 Junction Box
CM400 Controller
CM416 Fluxgate compass
CM120 Rudder Transducer
CM151/CM1012 Steer Motor or Hydraulic Pump.

System Description 1-2
______________________________________________________________________
To these components may be added a range of options to expand the system
into one which will handle most autopilot needs. A block diagram of a CM400N
system with its optional attachments is shown in Fig 1.1.
At the centre of the system is the Junction Box, which houses the control
microcomputer, the interfaces with other system components and the motor
drive electronics. The controller is the input device both for normal system
useage and for all installation settings.
The compass is a fluxgate type and has an internally damped pendulum
suspension which accommodates a wide range of pitch and roll. It has been
proved reliable and accurate in thousands of existing Coursemaster systems.
For best results, there are certain rules for mounting it on the vessel. These are
explained in Chapter 4.
The rudder transducer and the various steer drive options have similarly
been developed and refined through earlier Coursemaster systems. The choice
and installation of the drive is also described in Chapter 4.

1.2 THE CONTROL PANEL
The front panel of the controller (Fig 1.2) contains a 4 character display,
course error lamps and six keys. Most of the time, only the two keys on the left
are used. Chapter 2 contains full information on their use.

KEY FUNCTIONS
STANDBY
This switches the system on. When operating in any mode, this key returns the
system to STANDBY and switches the steering drive off. The key also cancels
alarms.
PILOT
Pressing this engages the autopilot and locks the vessel onto the current
heading
SWITCHING OFF
Pressing STANDBY and PILOT together turns the system OFF.

System Description 1-4
______________________________________________________________________
COURSE LEFT and RIGHT
Used to make course adjustments when in PILOT or to adjust system settings,
eg. rudder factor.
SELECT UP and DOWN
Used to change the sea-state setting, to display rudder angle or programmed
course, and to select system settings for adjustment.
Use of these keys is illustrated in the Quick Reference chart at the beginning of
this manual.
DISPLAY
In normal operation, the display shows the current magnetic heading, but can
be switched to show other information.
ERROR LAMPS
The course error lamps are operational for all modes of the system and
switch on for course errors greater than +/- 8.4 deg.
ALARMS
The alarm gives a single short beep when a key is pressed. Other alarm
patterns are accompanied by a message which identifies the problem. (See
Chap 2.) Examples include OFF COURSE (Code A01), which indicates that the
system has been off course for more than 12 sec and is in PILOT. HELM
ALERT (Code A02) comes up each 5 minutes to check that the helmsman is in
attendance when the system is in PILOT. Both of these alarms are cleared by
the STANDBY or PILOT key and the HELM ALERT may be disabled.
If a fault in the main processor or the link beteen the controller and the
junction box, the SYSTEM FAULT code, A08, together with an alarm pattern will
appear. If this occurs, SWITCH THE SYSTEM OFF.
