Introduction Wheelmark approval
The AP70 MK2 system are produced and tested in accordance with the European Council Directive 2014/90/EU on Marine Equipment modified by Commission Implementing Regulation (EU) 2018/773 (May 2018) (HCS and HSC). This means that these systems comply with the highest level of tests for non-military marine electronic navigation equipment existing today.
While the AP70 MK2 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 MK2 systems are not wheelmark approved when used with an AC70 computer. However an AC70 board installed in an AC85 can be used in a Wheelmark approved system.
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. 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 will also show which units that are part of the approval.
• • •
System overview
The AP70 MK2 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 on board It is important to become familiar with the configuration of the system prior to beginning the installation.

Mounting General
Mechanical installation of optional equipment are described in separate manuals following the units. These manuals can also be downloaded from our websites: www.navico.com/commercial.
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. Refer
The mounting location must allow for required working area when connecting the cables. Also ensure that the location for the computer units allow 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 result, install the display away from direct sunlight and in a location with 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 obtain the best use and performance from this product. Ensure you have as much separation as possible between different electrical equipment.
AP70 MK2 control unit
The nominal viewing distance for the AP70 MK2 is 0.85 m (2.79 ft).
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 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:
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 specification for the units.
Before starting the installation, be sure to turn electrical power off. If power is
Autopilot system, basic wiring principles
The AP70 MK2 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 can be connected to an autopilot computer.
In a standard system the CAN bus is powered by the AC80A, AC80S, SI80 or AC85 Autopilot computer. The AP70 MK2 control unit has separate power supply. The following sections describe installation of the components listed in the illustration below. Refer to separate manuals for detailed information about each interfacing unit.

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.

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 the DC negative of the backbone power supply
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.

System configuration General
When the autopilot installation is completed, the system must be configured and the commissioning procedures performed. Failure in setting up the autopilot correctly may prevent the autopilot from functioning properly.
For alert settings and alert handling, refer to the Operator manual.
Settings dialog and submenus
The system configuration settings are logically grouped in the Settings dialog, and each group is presented with an icon. This dialog is accessed by pressing the Settings icon available in all mode specific menus, or by double-clicking the Menu key.
Turning on for the first time
Before attempting to turn on the autopilot and perform an Installation set-up, the hardware installation and electrical installation must be completed and performed in accordance with the installation instructions The first time the autopilot system is started up and after a factory reset, you will be guided through a set of initial settings. On additional control heads, acknowledge language selection and cancel all other setup requests.
If the settings are not completed, you can configure the autopilot system manually as described in the following sections.
Network settings
Setup and selection of sources are done from the Network menu.
Selecting data sources
A data source can be a sensor or a device connected to the network, providing data to other devices.
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 turn-on of a group of network devices, data sources are automatically selected from an internal priority list. If a data source is connected to the network after the first turn-on, this will be identified and automatically selected if no other data source is selected for the given data type.
You can let the system select your sources automatically, or you can set up each source manually as described below.
System configuration | AP70 MK2 Installation Manual | 41
Auto select
The Auto Select option will look for all 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 the active source by ticking the preferred unit.

Network groups
The network group function is used to control parameter settings, either globally or in groups of units. The function is used on larger vessels where several 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 network groups from the units on the Main Bridge. If the backlight is adjusted in a display on the Main Bridge, it will change in all displays on the Main Bridge. It will not change the light settings in the Remote Station. If the damping is adjusted on the AP70 MK2 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 fulfil this requirement the AP70 MK2 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 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 and two AP70 MK2 control units are included in the master station. One of the AP70 MK2 control units is defined as the Master unit.
The illustration includes network group settings for each unit, showing how the units are defined as part of different network group stations.

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.
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.
System configuration | AP70 MK2 Installation Manual
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.)

Vessel configuration
¼
Note:
The unit of measurement in the dialog reflects your unit settings.
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.
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.
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.
HI w ork pr ofile LO w ork pr ofile Transition to HI work profile with increasing speed: 10 kn Transition speed set to 9 kn Transition to LO work profile with decreasing speed: 8 kn

Thruster inhibit speed
This feature will block the thruster from running above a set vessel speed. It is a safety feature to prevent, especially electrical on/off thrusters, from overheating if out of water or for instance a planing boat or in rough weather.
When the speed exceeds the set limit the thruster indication on the autopilot page will change as shown below.
Thruster(s) in use Thrusters unavailable when speed exceed inhibit limit
¼
Note:
The Thruster inhibit limit will only apply when speed source is Log or SOG, not if the speed is set manually.
Autopilot source
Select the main steering computer as the autopilot source.
Sea trials
Compass calibration
All magnetic compasses must be calibrated as part of the autopilot sea trial procedure.
Before the compass calibration is started, make sure that there is enough open water around the vessel to make a full turn.
54 |
The calibration should be done in calm sea conditions and with minimal wind to obtain good results. Follow the on-screen instruction.
1.
Start the calibration by selecting the Calibrate button in the device calibration dialog
System configuration | AP70 MK2 Installation Manual
2.
Follow the instructions on the screen 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.
Lubber line
20%
Magnitude of local field in % of earth’s magnetic field.
10°
Direction of local field with respect to lubber line. It can also be on the reciprocal.
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 offset
The difference between the compass lubber line and the boat’s 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 the center line of the boat is aligned with the bearing line pointing towards the object
3. 4.
Activate the device configuration dialog as shown below Ensure that the active compass is selected Change the offset parameter so that the bearing to the object and the compass readout becomes equal ¼
Note:
Make sure that both the compass heading and the bearing to the object have the same unit (Magnetic or True).
Drive configuration
The drive setup can usually be done while at dock, and only minor adjustments may be
required at sea trial. Refer “Dockside - Drive system” on page 47.
System configuration | AP70 MK2 Installation Manual | 55

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 53.
• -
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 53
•
Active work profile that should be used during sea trial 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.
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
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 57
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’s 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. 2. 3. -
Stabilize the vessel on a heading Set the speed as close to cruising speed as possible Start autotuning from the dialog The pilot will take control of the vessel. Autotuning may take up to 3 minutes to complete
System configuration | AP70 MK2 Installation Manual
After the autotuning is completed the autopilot will return to Standby 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. 4. 5.
Activate the Quick menu by pressing the Menu key Select Rudder and adjust according to the description below If required, slightly adjust 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 value is set too high. Steering becomes unstable and often the overshoot will in crease
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
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 depend 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 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.
System configuration | AP70 MK2 Installation Manual | 57
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 B C
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.
¼
Note:
As many boats turn 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.
