CAUTION
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.
SAFETY INSTRUCTIONS
Do not open the equipment
unless you are well familiar
with electrical circuits.
Only qualified personnel
should work inside the
equipment.
WARNING
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
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 special-
purpose mode for technicians.
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.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
Name: Warning Label (1)
Type: 86-003-1011
Code No.: 100-236-231
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.
For the figure eight mode, 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.
Set the turn rate properly.
Setting the too high rate may cause sudden
turn.
When connecting a geomagnetism
detection type heading sensor, correct
magnetic field deviation.
If an autopilot is used without the compens-
ation, unexpected course change may occur.

1. PRINCIPLE OF THE AUTOPILOT
Principle of Autopilot
An autopilot is an automatic device for steering a vessel and maintaining its
heading in an intended direction. Boat and ship operators can really appreciate
the advantages of the autopilot – It steers the boat for you so that you are free to
carry out navigational checks, trim adjustments, etc. or to simply relax and enjoy
the ride.
The NAVpilot-511/520 autopilot utilizes a proportional rate system to steer the
boat. This system is similar to the highly accurate and reliable systems used on
aircraft, missiles and space vehicles. The proportional rate autopilot provides the
necessary course correction to the steering system relative to the speed and
amount that the boat moves off course.
Dead band is the area (in degrees) that an autopilot is allowed to drift before
correcting the vessel’s course. Since your NAVpilot-511/520’s advanced
processor does not utilize a dead-band, it will not drift or wander, and will steer
the boat reliably and accurately, taking action if even a minute course error
occurs.
Because wandering is eliminated, the proportional rate autopilot uses less power
and lowers wear and tear on the steering system. Course correction is smooth,
and consistent, and the boat will not jerk back and forth at any speed.

1. PRINCIPLE OF THEAUTOPILOT
1-2
Principle of Operation
In the AUTO modes, the heading information from a heading sensor is
continuously compared with the course that is set on the autopilot’s controller. (in
the NAV mode, the course to the waypoint is received from a plotter connected
to the NAVpilot-511/520). With the boat on course, these two signals are equal.
If the boat drifts off course, the difference between the primary heading and the
set course will change proportionally and there will be an imbalance at a
comparator. The comparator’s output will then move up or down depending on
whether the course error is to the left or right of the set course.
The rudder will continue to turn the vessel until a balanced condition is obtained
at the comparator, at which point the drive to the rudder stops.
The rudder position is determined by a rudder reference unit and continuously
monitored by the processor unit.

2.2 Turning On/Off
Press the [STBY/POWER] key to turn the unit on. (For PG-500, see Note 2
shown below.) A beep sounds and the equipment proceeds in the sequence
shown below, showing product information and startup test results. The startup
test checks the ROM, RAM, backed up data and communication between the
control unit and processor unit, and also checks for the presence of heading
from the sensor and rudder angle information from the rudder angle indicator. If
NG appears, an appropriate message will also appear on the screen. If NG is
shown, contact your dealer for advice.

Startup sequence
After the startup test is completed, “STBY” appears on the screen. This means
that the equipment may now be operated manually.
Note 1: The first time you turn on the power, you are asked to select Normal,
Installation or Simulation mode. Rotate the course control knob to select
the appropriate mode, and then press it.
Note 2: When the Integrated Heading Sensor PG-500 is connected, turn on the
NAVpilot-511/520 and wait four minutes before leaving port in order to
allow time for the PG-500 heading data to stabilize.
Note 3: The example screens shown in this manual may not match the screens
you see on your display. The screen you see depends on your system
configuration and equipment settings.

3. STEERING MODES
The NAVpilot-511/520 system is capable of six primary steering modes: STBY
(manual), AUTO, NAV, TURN, REMOTE (FU and NFU) and DODGE.
3.1 STBY Mode
After turning on the power, the equipment goes to the STBY mode.
This is a manual steering mode. When sailing into or out of a harbor, steer the
vessel in the STBY mode by using the ship’s steering wheel (helm).
Press the [STBY] key.

3.2 AUTO Mode
3.2.1 Using the AUTO mode
The NAVpilot-511/520’s AUTO mode steers the boat automatically on a course
set by the operator.
Note: The AUTO mode will not compensate for the effects of wind or tide, which
can push you off course in the athwart ship direction. Use theAUTO mode
for short, straight voyages. Otherwise switch to the NAV mode which is
described on page 3-4.
1. Direct the boat to the intended course desired.
2. Press the [AUTO] key to activate theAuto mode.
Your boat will automatically maintain the current course at the moment the
[AUTO] key is pressed.
Whenever the heading deviates from the set course, the NAVpilot-511/520
automatically adjusts the rudder to return the boat to the set course.
3. To change or readjust the course setting in theAUTO mode, simply rotate the
course control knob to the desired course.
4. Press the [STBY] key to leaveAUTO steering in an emergency. You can
steer your boat by the helm.

3.2.2 ADVANCED AUTO mode
AUTO mode will maintain a set course, but your vessel’s course may be shifted
by the effects of current or wind.ADVANCED AUTO mode maintains a set
course while compensating for the effects of wind and tide. Note that your
NAVpilot-511/520 must be connected to a (GPS) which outputs own ship’s
position data (L/L) in NMEA0183 format to the NAVpilot-511/520.
In the ADVANCED AUTO mode, the NAVpilot-511/520 will calculate your course
based on your present position and heading, and by setting a virtual “waypoint”
in its memory to navigate towards. If either tide or wind begins to push you off
course, the NAVpilot-511/520’s processor will correct your heading accordingly.
In this mode, “AUTO” appears on the display.

3.3 NAV Mode
3.3.1 Starting the NAV mode
If a destination waypoint is set on a GPS / Plotter, the NAVpilot-511/520 can
receive this information and guide the boat to the destination waypoint as
determined by the plotter. To use the NAV mode, complete the following steps.
Note: It takes 15 seconds to activate the NAV mode after the NAVpilot-511/520
receives the above information.
1. Set the destination waypoint (or route) on the plotter.
2. Manually steer the boat towards the waypoint.
3. Press the [NAV] key.
You are asked which port is used for the NAV mode PORT 1 or PORT 2
( depending on menu setting) . Press the course control knob to go to the NAV
mode..
