www.navico.com/commercial and www.simrad-yachting.com.
The Wheelmark
The AP70 and AP80 systems are produced and tested in accordance with the European
Marine Equipment Directive 96/98. This means that the systems comply with the highest level
of tests for nonmilitary marine electronic navigation equipment existing today.
The Marine Equipment Directive 96/98/EC (MED), as amended by 98/95/EC for ships flying
EU or EFTA flags, applies to all new ships, to existing ships not previously carrying such
equipment, and to ships having their equipment replaced.
This means that all system components covered by annex A1 must be type-approved
accordingly and must carry the Wheelmark, which is a symbol of conformity with the Marine
Equipment Directive.
While the autopilot system may be installed on vessels not needing to comply with the
Marine Equipment Directive, those requiring compliance must have one Control unit set-up
as a “master unit in order for the installation to be approved.

Introduction
Wheelmark approval
The AP70 and AP80 systems are produced and tested in accordance with the European
Marine Equipment Directive 96/98. This means that these systems comply with the highest
level of tests for non-military marine electronic navigation equipment existing today.
While the AP70/AP80 may be installed on vessels not needing to comply with the Marine
Equipment Directive, those requiring compliance must have one control unit set-up as a
“master unit in order for the installation to be approved.
Navico has no responsibility for the incorrect installation or use of the autopilots, so it
is essential for the person in charge of the installation to be familiar with the relevant
requirements as well as with the contents of this manual, which covers correct installation of
the autopilot system.
¼ Note: AP70 systems are not wheelmark approved when used with an AC70 computer.
¼ Note: When a complete system (e.g. an autopilot system) is wheelmark approved, only the
main unit(s) in the system identifies the wheelmark approval (wheelmark symbol on the label
or reference in the software). This to avoid the misunderstanding that all optional units in a
system retain their wheelmark approval even if they are installed in a not approved system.
The type examination certificate (MED-B) for the wheelmarked system lists all optional
equipment that is part of the wheelmark approval. The EC Declaration of Conformity do also
show which units that are part of the approval.
Spare parts and accessories
List of spare parts and accessories for the AP70/AP80 system can be found on our websites.
System overview
The AP70/AP80 systems include several modules that need to be mounted in different
locations on the vessel and that need to interface with at least three different systems on the
boat:
The boat’s steering system
The boat’s electrical system (input power)
Other equipment onboard
It is important to become familiar with the configuration of the system prior to beginning the
installation. Refer to illustrations on page 8 onwards.

Mounting
General
Mechanical installation of optional equipment are described in separate manuals following
the units. These manuals can also be downloaded from out websites:
www.navico.com/commercial and www.simrad-yachting.com.
Mounting location
The units should be mounted with special regard to the units environmental protection,
temperature range and cable length. Poor ventilation may cause the units to overheat. wRefer
“Specifications” on page 70.
The mounting location must allow for required working area when connecting the cables.
Also ensure that the location for the computer units allows viewing the board’s LED
indicators.
The mounting surface needs to be structurally strong, with as little vibration as possible. If
possible mount the unit close to the edges of a panel to minimize vibration.
Ensure that any holes cut are in a safe position and will not weaken the boat’s structure. If
in doubt, consult a qualified boat builder. Ensure that there are no hidden electrical wires or
other parts behind the panel.
The control unit should be mounted so that the operator can easily use the controls and
clearly see the display screen. For best results install the display out of direct sunlight, and on
a location that have minimal glare from windows or bright objects.
When panel mounting the control unit and the remotes, the mounting surface must be flat
and even to within 0.5 mm.
The units conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but
proper installation is required to get best use and performance from this product. Ensure you
have as much separation as possible between different electrical equipment.
AP70 and AP80 control units
Avoid mounting a control unit where it is easily exposed to sunlight, as this will shorten the
lifetime of the display. If this is not possible, make sure the unit is always covered with the
optional protective cover when not in use.

Wiring | AP70/AP80 Installation Manual
Wiring
Wiring guidelines
CAN network cables and other signal cables (i.e. compass, feedback, NMEA) should not be
run in parallel with other cables carrying radio frequency or high current, such as VHF and SSB
transmitters, battery chargers/generators, and winches.
Don’t make sharp bends in the cables, and avoid running cables in a way that allows water to
flow down into the connectors. If required, make drip and service loops.
If cables are shortened, lengthened or re-terminated, do insulate and protect all wiring
connections.
Most of the units are communicating on the CAN bus with drop cables. Try mounting the
units within the standard cable length supplied with each unit. Additional cables and cable
extensions are available from our distributors.
!
Warning: Before starting the installation, be sure to turn electrical power off. If power
is left on or turned on during the installation, fire, electrical shock, or other serious injury
may occur. Be sure that the voltage of the power supply is compatible with the spec for the
units!
The autopilot system, basic wiring principles
The AP70 and AP80 autopilot system use a CAN bus backbone which makes it simple to
interface to SimNet and NMEA 2000 devices.
NMEA 0183 devices, rudder feedbacks and other control devices connects to an autopilot
computer.
In a standard system the CAN bus is powered by the AC80A, AC80S, SI80 or AC85 Autopilot
computer. The AP70/AP80 control units have separate power supply. Other SimNet/NMEA
devices are powered by the CAN bus.
The following sections describe installation of the components listed in the illustration below.
Refer to separate manuals for detailed information about each interfacing unit.

Wiring | AP70/AP80 Installation Manual
The CAN bus
The CAN bus is based on the well known SimNet plug & play concept and on the NMEA 2000
SAE J1939 protocol. Hard wiring is based on standard NMEA 2000 cables with Micro-C type
connectors and joiners.
The bus consists of a linear backbone using drop cables and Micro-C T-joiners for connecting
NMEA 2000 and SimNet devices.
The bus has a maximum cable length of 150 m (500 ft), and a drop cable has a maximum
length of 6 m (20 ft).
In a default autopilot system the CAN bus backbone expands from the AC80A or AC80S
Autopilot computer, which supplies power to the backbone. There will always be a female
connector in the expanding end of the backbone cables.
For powering the CAN bus, see “Powering the CAN bus” on page 23.

requirements.
Planning and installing a network backbone
Plan the network carefully
- It is recommended to create a diagram of the network prior to starting the installation
Run the backbone between the locations of all CAN devices you want to install
- I must be less than 6 m (20 ft) cable run from a device to the backbone
Consider the load/current draw from the devices
- Refer “Network LEN” on page 24
For network cables and components, refer to our website.

Wiring | AP70/AP80 Installation Manual
Terminating the CAN bus
The CAN bus must have a terminator at each end of the backbone.
In a default autopilot system the CAN bus expands from the AC80A, AC80S or AC85 Autopilot
computer. This computer includes a terminator on the SI80 board, enabled by the micro
switch.
- Set the switch to ON when the SI80 board is at the end of the CAN bus
- Set the switch to OFF when the SI80 board is used as additional power supply to the CAN
bus
Factory default setting of SI80 terminator is OFF.
For location of the dip switch, refer to the illustrations inside the computer unit.
A terminator in the other end of the CAN bus can be of the following:
An SI board (in SI80, AC80A, AC80S or AC85 computer) with enabled terminator
A power cable with built in terminator (plug marked 120 ohm)
A single terminator plug (marked 120 ohm)
Shield connection
It is required to use shielded cables to meet radio frequency interference requirements as
defined in the NMEA 2000 specification:
The shield shall not be electrically connected within the interface to the electronic device
chassis or ground
The shield shall be electrically continuous through the network connection
The shield shall be connected to ground at a single point, normally the ship’s ground at the
source of network power
Power supply
¼ Note: Wheelmark/US Coast Guard approved systems require a Power Failure alarm. In such
installations the master station control unit and the autopilot computer with the SI80 board
for CAN bus supply must be connected to different independent power supplies.
¼ Note: It is recommended to install an external on/off switch for the Autopilot Computer
power supply.
¼ Note: Do not connect the power cable to the same terminals as the start batteries, drive
units, thruster or other high current products
¼ Note: If joining to an existing NMEA 2000 network or similar CAN bus network that has its
own power supply, use an NMEA 2000 Gateway to isolate the two power supplies.
Powering the CAN bus
In a default autopilot system the SI80 board (in the SI80, AC80A, AC80S or AC85 computer) is
used for powering the CAN bus backbone.
For larger systems additional power should be added at a central point in the backbone to
balance the voltage drop of the network. Additional power should be supplied by using an
SI80 board. Refer “Network LEN” on page 24.

Polarity protection
For supply to SI80 and AC70 boards, pay special attention to polarity protection.
The main supply fuse for these units is supplied loose in the bag with the cable plugs, and it
should not be put in place before polarity is checked.
1. Connect the power wires, and verify that the green diode is lit
- A red diode indicates wrong polarity, and the wires must be swapped
2. Switch off the power supply voltage and put the fuse into correct position
The illustration shows power terminal and diodes on the AC70 board. For location of
terminals, fuse and diodes on the board, refer to the illustration inside the computer unit.

The autopilot system has excellent radio frequency interference protection and all units use
the autopilot computers as a common ground/shield connection. The units must therefore
have a proper ground connection to the hull.
Termination, general
Power and signal cables connect with screw terminals or terminal blocks on the board inside
the computer unit. Refer connection details on the following pages.
1. Insert the cable through an appropriate cable gland or slot
2. Strip of the cable insulation. Provide sufficient wire length so that the plug-in terminals can be
easily connected and disconnected
3. Pull out each terminal blocks from the board before connecting the wires
4. Terminate the wires to the terminal blocks according to the terminal specification in the fol-
lowing pages
5. Connect the terminal blocks to the board
6. Crimp a Faston terminal to the screen and connect to the grounding plug-in terminal on the
board, or on the grounding list
7. Secure the cables by using cable ties
Connecting the computers to the CAN bus

devices. Data can be of different type such as compass data, apparent wind data, calculated
wind data, depth data, etc.
Source selection is required on initial start up of the system, if any part of the CAN bus
network has been changed or replaced, or if an alternative source is made available for a
given data type and this source has not been selected automatically.
At the first time turn on of a group of SimNet interconnected products, data sources are
automatically selected from an internal SimNet priority list. If a data source is connected to
SimNet after the first time turn on, this will be identified and automatically selected if no other
data source already is selected for the given data type.
You can let the system automatically select your sources, or set up each source manually as
described below.
Auto select
The Auto Select option will look for all SimNet sources connected to the network. If more
than one source is available for each data type, the system will automatically select from an
internal priority list.
The Auto select function is mainly for situations where the automatic source selection needs
to be updated because a selected data source is not supplying data or has been physically
replaced with another one. The update secures that the existing source selections are valid
and maintained. Missing sources are either automatically exchanged with an alternative
source from the list of available sources for the given data type, or the replacing source is
selected.
Manual source selection
You can manually select the preferred source. This is useful if you have more than one of the
same type of device on the network.
Available sources are listed as shown in the example below. You select active source by
ticking the preferred unit.
Group selection
The autopilot system can use data sources that all other products on the network use, or
select individual sources for the autopilot system.
If the group is set to Simrad, any changes to a source will also affect other systems on the
network.
If the group is None, the selected source will be used for the autopilot system only.
In the example below the steering compass is common for all systems on the network.
Advanced selection
Allows the advanced selection of sources available on the network.

SimNet groups
The SimNet Group function is used to control parameter settings, either globally or in groups
of units. The function is used on larger vessels where several SimNet units are connected via
the network. By assigning several units to the same group, a parameter update on one unit
will have the same effect on the rest of the group members.
The illustration below shows a two station installation. Units in the Remote Station have their
backlight and damping settings in different SimNet Groups from the units on the Main Bridge.
If the back light is adjusted on a display on the Main Bridge, it will change on all displays on
the Main Bridge. It will not change the light settings in the Remote Station. If the damping is
adjusted on the AP80 control unit, this will not affect damping on the NSE unit in the remote
station.

Master systems
The international standard for heading control systems (ISO 11674/ISO 16329) requires
controlled command transfer when remote stations are provided. The delegation of control
to the remote station and the return of control shall be incorporated in the autopilot system,
and shall avoid unintended operation from a remote station.
To fulfill this requirement the AP70/AP80 system includes a Master function. This is used in
larger Wheelmarked systems where you permanently want to control command transfer to
remote stations.
In a Master system, one steering station is defined as the Master station. There can be several
| 45
System conguration | AP70/AP80 Installation Manual
control units in a master station, but only one of them can be set as the Master unit.
All units included in the master station will be unlocked, and command transfer within the
master group will be as in an open system.
Units not included in the master station will be locked. It is not possible to take command
from units outside the master station unless the master control unit opens for this. All units
outside the master station will have a lock symbol.
In the illustration below the main bridge is defined as master station. One QS80, one AP80
control unit and one AP70 control unit are included in the master station. The AP80 control
unit is defined as the Master unit.

Damping
Controls how quickly the display updates values from sensors.
Increasing the damping applies more averaging or smoothing of the data update rate on the

The installation setup includes dockside and seatrial configuration of drives, together with
compass calibration.
When the autopilot is delivered from factory AND ANY TIME AFTER AN AUTOPILOT RESET HAS
BEEN PERFORMED, the installation settings are all reset to factory preset (default) values. A
notification will be displayed, and a complete setup has to be made.
¼ Note: The Installation settings can only be accessed in STBY mode.
Warning: The installation settings must be performed as part of the
commissioning of the autopilot system. Failure to do so correctly may
prohibit the autopilot from functioning properly!
¼ Note: The seatrial settings are dependent on successful completion of the dockside settings.

Advanced rudder settings
Minimum rudder
Some boats may have a tendency of not responding to small rudder commands around the
course keeping position because of a small rudder, a rudder deadband, whirls/disturbance of
the water-stream passing the rudder or it is a single nozzle water jet boat.
By manually adjusting the minimum rudder function, the course keeping performance might
be improved on some boats. This will however increase the rudder activity.
¼ Note: Only set a value for minimum rudder if it proves to give a better course keeping
performance in calm sea. It should be set after the autotune has been performed and a fine
tuning of the rudder parameter.
Rudder deadband
Prevents the rudder from hunting caused by high rudder speed and/or overshoot in the
steering gear.
Deadband mode
Auto or Manual (default: Auto).
Auto: The rudder deadband is adaptive and is continuously operative. It will also optimize the
deadband to the speed of the vessel and the pressure on the rudder.
Manual: If the Auto setting doesn’t perform properly due to extreme rudder speed and/or
overshoot, it can be adjusted manually.
Find the lowest possible value that will prevent the rudder from continuous hunting. A wide
deadband will cause inaccurate steering. It is recommended to check rudder stability in AUTO
mode at cruising speed to get pressure on the rudder. (Slight hunting observed dockside may
disappear at cruising speed.)

Boat type
The boat type setting is used by the system to select appropriate preset steering parameters.
It will also affect available autopilot features.
Boat length
The boat length affects the steering parameters.
Range: 5 - 500 (m)
Cruising speed
The cruising speed is used if no speed info is available, and if manual speed is set to Auto.
It is also used by the autopilot system to calculate steering parameters.
Range: 2 - 50 (kn)
Default: 15 (kn)
Transition speed
¼ Note: Only available if the boat type is set to planing.
The transition speed is the speed at which the system automatically changes from LOW to
HIGH work profile.
These two work profiles are automatically defined when you set the boat profile to planing.
The work profiles are set up with high and low speed parameters to control the different
steering characteristics before and after planing.
On power boats it is recommended that you set a value that represents the speed where the
hull begins to plane or the speed where you change from slow to cruising speed.

Seatrials
Compass calibration
All magnetic compasses must be calibrated as part of the autopilot seatrial procedure.
Before the compass calibration is started, make sure that there is enough open water around
the vessel to make a full turn.
The calibration should be done in calm sea conditions and with minimal wind to obtain good
results. Follow the on-screen instruction, and use about 60-90 seconds to make a full circle.
1. Start the calibration by selecting the Calibrate button in the device calibration dialog
2. Follow the online instructions
During the calibration, the compass will measure the magnitude and direction of the local
magnetic field.
If the local magnetic field is stronger than the earth’s magnetic field (the local field is reading
more than 100%), the compass calibration will fail
If the local field is reading more than 30%, you should look for any interfering magnetic
objects and remove them, or you should move the compass to a different location. The
(local) field angle will guide you to the local interfering magnetic object.
Magnitude of local eld in % of
earth’s magnetic eld.
Lubber line
Direction of local eld with respect
to lubber line. It can also be on the
reciprocal.
10°
20%
¼ Note: Calibration must be made on the compass that is active for the autopilot. If another
model compass from Simrad or another manufacturer is installed, refer to the calibration
instruction for that compass.
¼ Note: In certain areas and at high latitudes the local magnetic interference becomes more
significant and heading errors exceeding ±3° may have to be accepted.
Compass mounting oset
The difference between the compass lubber line and the boats center line should be
compensated for.
1. Find the bearing from the boat position to a visible object. Use a chart or a chart plotter
2. Steer the boat so that the center line of the boat is aligned with the bearing line pointing
towards the object
3. Activate the device configuration dialog as shown below
- Ensure that the active compass is selected
4. Change the offset parameter so that the bearing to the object and the compass readout
becomes equal
| 55
System conguration | AP70/AP80 Installation Manual
¼ Note: Make sure that both the compass heading and the bearing to the object have the same
unit (Magnetic or True).
Drive conguration
The drive setup can usually be done while at dock, and only minor adjustments may be
required at seatrial.
Refer “Dockside - Drive system on page 46.
Boat settings
These settings are used as initial values for the vessel. Each of them can be changed in the
different work profile settings.
Turn type and Turn value
Used for selecting how you want to control the vessels turn: either by defining the Rate of
Turn (Rate) or the radius.
Rate range: 5°/minute - 720°/minute
Radius range: 10 (m) - 10 (NM)
- The minimum radius can however never be less than the value corresponding to a Rate of
Turn = 720°/minute at the set Cruising speed
Default: Rate
Initial value: Determined during sea trial
Track approach angle
Defines the angle used when the vessel is approaching a leg.
This setting is used both when you start navigating and when you use track offset.
Range: 5° - 60°
Default: 30°
Tuning the autopilot for optimum steering performance
Providing you have entered correct vessel type, length and cruising speed, you may not have
to perform further manual- or automatic tuning. Refer Vessel configuration on page 52.
¼ Notes:
If steering compass is magnetic type, perform any autopilot tuning steering East or West, as
this will yield the best-balanced parameters
The speed during tuning should be as close as possible to cruising speed. Ensure that this is
set correctly and as described in “Vessel configuration” on page 52
Active work profile that should be used during seatrial depends on vessel type.
- For displacement boats NORMAL work profile should be used
- Planing boats will have to tune both LO SPD and HI SPD work profiles
All tuning should always be performed in open waters at a safe distance from other traffic
Initial automatic learning process
Before doing any manual or automatic tuning the autopilot needs to learn the turn
characteristic of the boat. This is done in AUTO mode by making a major course change (min
90°) to port and starboard. For this test you may use the U-turn function (180°).
The autopilot will now find the appropriate amount of rudder to maintain the set turn rate
during the turn. See also Turn type and Turn value” on page 55.
When the automatic learning process is done, now proceed as follows to verify satisfactorily
steering:
1. Stabilize the vessel on a heading, and then select AUTO mode
2. Observe course keeping and rudder commands
- The autopilot should keep the vessel on the set heading within an average of +/-1 degree,
providing calm sea and wind
56 |
System conguration | AP70/AP80 Installation Manual
3. Make some small and bigger heading changes to port and starboard and observe how the
vessel settles on the new heading
- The vessel should have a minimum of overshoot (see example “Manual tuning” on page
56
If the autopilot is not keeping the heading satisfactorily or not making the turns satisfactorily,
you may now either try the Autotune function or go directly to Manual tuning.
¼ Note: If the vessel is more than approximately 30 m/100 ft it may be unpractical to perform
Autotune, and it is suggested to proceed with manual tuning.
Both Autotune and Manual tuning should be performed in calm or moderate sea conditions.
Autotuning
When performing an Autotune, the vessel will automatically be taken through a number of
S-turns. Based on the vessel behavior, the autopilot will automatically set the most important
steering parameters (Rudder and Counter rudder). The scaling factors for the parameters are
set automatically as a function of the set boat type.
1. Stabilize the vessel on a heading
2. Set the speed is as close to cruising speed as possible
3. Start autotuning from the dialog
- The pilot will take control of the vessel. Autotuning may take up to 3 minutes to complete
After the autotuning is completed the autopilot will return to STBY mode, and the rudder
must be controlled manually.
¼ Note: Autotuning can be stopped at any time by selecting Cancel.
Manual tuning
1. Stabilize the vessel on a heading, and then select AUTO mode
2. Set the speed as close to cruising speed as possible
3. Activate the Quick menu by pressing the MENU key
4. Select Rudder and adjust according to the description below
5. If required, adjust slightly Counter rudder
Rudder
This parameter determines the ratio between commanded rudder and the heading error. The
higher rudder value the more rudder is applied.
A. The the value is set too high. Steering becomes unstable and often the overshoot will
increase
B. Rudder is too small. It will take a long time to compensate for a heading error, and the
autopilot will fail to keep a steady course
A B
Range: 0.05 - 4.00
Default: Defined by system based on boat type and length
Counter rudder
Counter rudder is the amount of counteracting (opposite) rudder applied to stop the turn at
the end of a major course change.
The settings depends on vessel’s characteristics, loaded/ballast conditions and rate of turn.
If the vessel has good dynamic stability, relatively small settings will be sufficient
An unstable vessel will require high settings
| 57
System conguration | AP70/AP80 Installation Manual
The greater the vessel’s inertia, the greater value will be required
Increasing counter rudder settings may result in some higher rudder activity also when
steering a straight course.
The best way of checking the value of the Counter rudder setting is when making turns.
The figures illustrate the effects of various Counter Rudder settings;
A. Counter rudder too low; overshoot response
B. Counter rudder too high; sluggish and creeping response
C. Correct setting or counter rudder; ideal response
A
C
B
Perform various course changes and observe how the boat settles on the new heading.
Start with small changes, 10-20 degrees and proceed with bigger changes, 60-90 degrees.
Adjust Counter rudder value to obtain best possible response as illustration C below.
¼ Note: As many boats turns differently to port versus starboard (due to propeller rotation
direction), do the course changes in both directions. You may end up with a compromise
setting of Counter rudder that gives a little overshoot to one side and a bit sluggish response
to the other.
Range: 0.05 - 32.00
Default: Defined by system based on boat type and length

The alarm system | AP70/AP80 Installation Manual
Magnetic variation missing
If heading source is set to be adjusted for magnetic variation, variation is taken from available
sensors in following order: Position source – Navigation source – Compass – any other
variation available on CAN bus. If variation disappears, last valid variation will be used until
automatic steering is cancelled and heading shown will then be corrected according to
alternative variation in the order given above.
Jump in heading data
If there is an abnormal heading jump in steering compass heading, an alarm (check heading)
will be given and a smooth transition to new heading will take place. There may also be a
compass difference alarm if a monitor compass is in use.
Speed sensor lost
If speed in use is lost there will be an alarm and smooth transition (2 min filter) to fallback
speed. Speed for steering and speed for navigation will use following use priority and fallback:
Steering: STW STW backup SOG SOG backup Manual speed Cursing speed
Navigation: SOG SOG backup STW STW backup Manual speed Cruising speed
Position data missing
During NoDrift steering, alarm is given and a smooth transition to position backup source
takes place. If no position backup steering source, steering mode will change to auto heading.
Navigation data missing
If lost during track/nav. steering, give alarm and change to auto heading steering.
Local supply voltage missing
When control unit(s) and CAN bus have different power source, alarm will be given on active
control unit with sound and flashing red power button led (display will go “black”). Main
steering computer will go to STBY mode and activate alarm on all other control units.
CAN bus supply voltage missing
Active control unit will give local alarm and rudder/thruster drive units will go to STBY mode.
Rudder/thruster drive computer failure
Alarm will be given and the ready signal to the steering /thruster gear will disappears. If sw
failure, there will be a watchdog restart of failing drive computer. The autopilot steering
computer will try to maintain steering as far as possible with remaining drive computers.
If the faulty unit is the autopilot steering computer, autopilot backup computer has to be
selected manually (ref. Menu- source selection).
List of possible alarms and corrective actions
The next pages includes a list of all alarms generated by the autopilot system.
The AP70/AP80 control units might also display alarms received from other units connected
to the system. Refer separate documentation for the relevant equipment for further
descriptions of these alarms.
