SAFETY INSTRUCTIONS

WARNING

Do not open the equipment
unless you are well familiar
with electrical circuits.

Only qualified personnel

ELECTRICAL

SHOCK

HAZARD

Do not set the course changing speed
too high.

The boat will be turned too sharply at the
course change, which could create a very
dangerous situation.

Do not use the autopilot in the
following situation:

Harbor entrance or narrow channel
Where vessels change course often,
such as a cape or small island

should work inside the
equipment.

WARNING

Do not use the ORBIT mode in rough
sea.

Because the boat turns a 360-degree circle
around the waypoint a large wave or strong
wind can cause the boat to capsize.

Confirm that no objection is in the
general vicinity of the waypoint.

The distance from the waypoint to the
turning point depends on boat's speed.

Do not use the SIMULATION mode on
the boat.

The rudder may move. This is special­purpose mode for technicians.

CAUTION

Observe the following cautions when
using the autopilot:

Maintain a vigilant watch
Watch for drifting of vessel

In an emergency, manually steer the
vessel.

The autopilot cannot avoid vessels, etc.
automatically.

Do not use the SIMULATION mode on
the boat.

The rudder may move. This is special­purpose mode for technicians.

In case of power failure turn off the
autopilot or manually steer the vessel.

Leaving the equipment in the AUTO or
NAV mode during power failure will cause
wear on the rudder mechanism.

Use the correct fuse.

Use of a wrong fuse can cause fire or
damage the equipment.

WARNING LABEL
A warning label is attached to the
processor unit. Do not remove the
label. If the label is missing or damaged,
contact your dealer about replacement.

To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

1. PRINCIPLE OF THE AUTOPILOT

Principle of Autopilot

Autopilot is an automatic device for steering a vessel maintaining its heading in
an intended direction. Anyone can appreciate the advantages of the autopilot –
being free to carry out navigational checks, trim adjustments or simply to relax
and enjoy.

The autopilot utilizes a proportional rat e system to steer the boat. The
proportional rate system is similar to the highly accurate and reliable system
used on aircraft, missiles and space vehicles. The proportional rate autopilot
provides the necessary course correction to the steering gears in propo r tion to
the speed and amount the boat m oves off course.

With the removal of the dead band, the aut opilot no longer wanders within a
dead band but now steers a prescribed course, taking action within the presence
of even a minute course error. The amount of action depends on the course
error detected; that is, when the course error rate is small a very low helm
correction rate is applied.

Because the wandering is eliminated, the proportional rate autopilot has the
advantages of low power consumption and low wear and tear on the autopilot
and the steering system. Off-course correction is smooth, not jerking back and
forth at full speed.

1-1

1. PRINCIPLE OF THE AUTOPILOT

Principle of Operation

In the AUTO modes, the heading information from an associated sensor is
continuously compared with the set course (in the NAV mode, the course to the
waypoint set on the plotter connected). With the boat on course, the two signals
are equal.

If the boat goes off course, the difference between the primary heading and the
set course will change proportionally and there will be an imbalance at the
comparator, whose output will move up or down depending on whether the
course error is to the left or right of the set course.

The rudder continues to move until a balanc ed condition is obtained at the
comparator, at which point the drive switches off.

To set the rudder when the boat is off-course, the rudder signal is generated at
the rudder reference unit, then deliver ed the processor unit.

Selecting the method of enteri ng the parameter

The NAVpilot-500 has an automatic adjustment feature which sets up the equipment
according to ship’s characteristics and sea state for optimum performance in the AUTO and
NAV modes. Further, a self-learning algorithm is incorporated: Parameters for rudder ratio,
counter rudder and auto trim gains, input at the sea trial after the installation and
experiences of your boat, are stored in memory for navigation in the future.

Note that the default settings for FULL-AUTO have been detected based on the BOAT
TYPE and BOAT LENGTH on installing.

You may set sea state as follows:

1. Rotate the [ENTER] knob to select “SEA STATE” from the PARAMETER SETUP menu.

4. MENU OPERATION

WEATHER

When the sea is rough, the boat’s heading fluctuates to port and starboard. If the rudder is
driven very often to maintain the set course, the helm mechanism may wear out. To prevent
this, the weather adjustment makes the NAVpilot-500 insensitive to minute course
deviations. You may choose a degree between 1° to 10°. Until the course deviation exceeds
the selected setting, steering to correct the heading will not be initiated.

The illustration below shows boat’s track lines with weather setting 3° and 7°. When 7° is
set, for example, the rudder is not driven until the course deviation exceeds 7°. Increasing
the setting reduces activation of the steering gear, however the boat tends to zigzag. When
the sea is calm, set a smaller value.

RUDDER GAIN

When the boat’s heading deviates from the set course, the NAVpilot-500 adjusts the rudder
to correct it. The rudder angle (number of degrees) which is steered against every degree of
course deviation is known as the rudder gain.

The following illustrations show how many degrees the NAVpilot-500 steers the rudder in
order to nullify 10 degrees of course deviation with various settings of the rudder gain.

COUNTER RUDDER

If the boat is heavily loaded, the heading will turn excessively by inertia, passing the new
course. Then, the NAVpilot-500 will steer the rudder to the opposite side and the heading
will turn in that direction excessively again. In an extreme case the heading oscillates
several times until it finally settles in the new course. An adjustment known as “counter
rudder” prevents this kind of oscillation.

Counter rudder is usually not required for small boats. When your boat zigzags a lot before
settling in the new course, increase the setting.

4. MENU OPERATION

Adjusting the sensitivity in mon itoring the boat’s trim

The NAVpilot-500 continually monitors the boat’s trim in order to keep the trim sensitivity
optimum. A lower setting is common because boat’s trim usually does not change quickly. A
large number changes the trim compensation value more frequently. Too high a setting may
result in the following problems.

• Trim sensitivity is over-affected, resulting that a trim appears in both port and starboard

directions alternately.

• Trim compensation mechanism responds to the yawing, resulting in more serious

oscillation of ship’s heading.

4. MENU OPERATION

When towing the net

When a boat is in tow of the fishing gear, its stern is “dragged” by the net. This causes the
boat to stray from its intended course. To keep the boat on course, you need to adjust the
trim manually, which can be bothersome. If you do not want to be bothered with trim
adjustments, you can enable the automatic towing function to have the trim automatically
adjusted. It is indispensable for trawlers and purse seiners.
