Basic operation
Safe operation with the autopilot
Warning:
An autopilot is a useful navigational aid, but DOES NOT replace a human navigator.
Warning:
Ensure the autopilot has been installed correctly, commissioned and calibrated before use.
Do not use automatic steering when:
• In heavy traffic areas or in narrow waters
• In poor visibility or extreme sea conditions
• When in areas where use of an autopilot is prohibited by law
When using an autopilot:
• Do not leave the helm unattended
• Do not place any magnetic material or equipment near the heading sensor used by the autopilot system
• Verify at regular intervals the course and position of the vessel
• Always switch the autopilot to standby and reduce speed in due time to avoid hazardous situations
Autopilot alerts
For safety reasons it is recommended to turn on all autopilot alerts when operating the autopilot.
For more information, refer to
"The alert system" on page 36.
External system selector
IMO resolution MSC.64(67) and other regulations require that an external switch is used for controlling change-over from manual to automatic steering.
The mode descriptions in this manual assumes that an external system selector has opened for autopilot operation, or that no external selector is installed.
Manual steering
When an external system selector is set to manual steering, the autopilot will be disengaged.
The control unit will display information as in Standby mode. It is not possible to change to
FU, NFU or to any automatic mode. The menus can however be used, alerts acknowledged and illumination adjusted.
When the autopilot is disengaged by an external switch, this will be indicated in the mode display.
Autopilot operation
When the external selector is set to automatic steering, the autopilot will go directly to AUTO heading mode with present heading as set reference. The autopilot can then be used in all operational modes.
External EVC override (SG05 PRO)
You may at any time, irrespective of the autopilot mode, take manual control of the steering by means of the helm. The autopilot will then go to Standby mode and display Override to indicate the steering is from the helm. Autosteering can be resumed by pressing the AUTO or the WORK key.
11 Basic operation | AP70 MK2 Operator Manual
The Pendulum feature
The pendulum feature is intended for pendulum ferries where it is required to turn the heading 180° when the vessel is going backwards. The feature can be included in systems equipped with SD80 or AD80 boards.
The pendulum feature is activated by using an external switch. When the contact is closed, the heading from the main compass and the monitor compass will change 180°. The heading is changed before heading data enters the CAN bus network, and all devices on the bus will pick up the modified heading.
Ú Note: The system must be configured for the pendulum feature as described in the separate installation manual.
Turning the system ON and OFF
Turning ON
Press the standby/brilliance key to turn the system ON.
The system will be ON as long as power is connected.
Switch the system to sleep mode
Press and hold the Standby/Brilliance key on an active control unit to switch the system to sleep mode.
During the shut-down procedure the system will automatically go to Standby mode before it is turned off.
Ú Note: The Standby/Brilliance key will remain lit on units that are in sleep mode. To stop the system from drawing current a separate breaker should be installed.
Taking command
You can take command from any control unit and/or remote by pressing the Command key.
In an open system (no command transfer restrictions) you will get immediate control from the control unit requesting command. A steering handle without a Command key will get control when the lever is operated.
In a multi-station system with active lock function, the command request must be confirmed on the active control unit.
Active/passive units
In a system including more than one control unit and/or remote units, only one unit can be in control at a time. All other units will be passive.
A passive unit is indicated with a passive icon in the mode status field.
On a passive/locked unit illumination can be adjusted, alert sound can be locally silenced, and the Command key can be used for requesting command. All other functions are unavailable.

Installation manual for the autopilot system.
The thruster(s) can be configured to different work profiles, and the work profile in use will then decide if the vessel can be controlled by rudder, thruster(s), or both rudder and thruster(s).
Thruster settings
Two settings affect how the thrusters are used by the autopilot:
• Thruster inhibit speed - set during dockside setup
- This setting will turn the thrusters OFF when the vessel is running above a set speed limit
• The Thruster assist function - set when configuring the thrusters for the work profiles
- ON: the thrusters will automatically be used by the autopilot system. If the thrusters are turned off when the vessel increases inhibited speed, the thrusters will automatically be turned on again when the speed goes below the inhibited limit
- OFF: you must manually turn thrusters ON

Delegation of control in multiple station systems
Steering stations
An autopilot system with multiple stations can be set up with different steering stations. This setting is done during installation of the system, and the separate autopilot Installation manual details how to define network groups.
The network group Station settings determines lock/unlock and command transfer principle between active and passive control units. Based on this setting the system is defined as an open system or a master system as described in the following sections.
On a locked unit you can only adjust illumination and silence an alert locally. All other functions are unavailable.
Open systems
In a default installation the system is open, and control is accessible from every control unit connected to the autopilot system. One control unit is active and provides the user with access to all functions. All remaining control units are inactive and have no effect on course changes. A single press on the Command key on an inactive control unit will allow transfer of command and make the unit active. On steering levers without a command key, command is taken by moving the lever.
Locking and unlocking units in an open system
You can temporarily lock units in an open system if you want to avoid accidental control from another control unit.
An active control unit can lock and unlock all passive control units.
1.
Activate the lock function from any active control unit by a single press on the Command key
2.
Deactivate the function with a second press on the Command key
Active locking function is indicated with a lock symbol on both active and passive units.
Taking command from a locked unit in an Open system
1.
Press the Command key on the locked unit
- A dialog will be shown on the unit requesting command ( A )
- A command request dialog will be shown on the active unit, accompanied by a 2 second sound ( B )
2.

- All passive units will be opened for command transfer, indicated as below
- The lock function will be deactivated, and the lock symbol removed from all units
3.
Take command on selected remote unit
Delegation of control in multiple station systems | AP70 MK2 Operator Manual 17
Master systems
The international standard for heading control systems (ISO 11674/16329) 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
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 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 stations.
Defining a Master system
A master station is usually defined and units assigned to the master station during system setup. Refer to the separate autopilot installation manual for details.
Ú Note: When a network group Station is set to Master, one control unit in this steering station has to be defined as the Master unit.
18 Delegation of control in multiple station systems | AP70 MK2 Operator Manual
In a Master system command can be transferred to a remote unit either by opening the system for remote operation from the Master unit, or by requesting command from one of the remote units.

Autopilot modes
The autopilot has several steering modes. The number of modes and features within the mode depend on the autopilot computer, the boat type and available inputs.
External system selector
An external switch can be used for controlling change over from manual to automatic steering.
The mode descriptions in the following pages assumes that an external system selector has opened for autopilot operation, or that no external selector is installed.
Hand steering
Standby mode
Standby mode is used when you steer the boat at the helm.
• Switch to Standby mode by pressing the STBY key.
Ú Note: If sensor data vital for autopilot operation (e.g. rudder response) is lost when the autopilot is running in an automatic mode, the system will automatically switch to
Standby mode.
Non-Follow Up (NFU) mode
In NFU mode you can use the port and starboard keys on the controller to operate the rudder. The rudder will move as long as the key is pressed.
• Switch to NFU mode by pressing one of the port or starboard keys when the autopilot is in Standby mode or FU mode.

Automatic modes
This autopilot system includes two automatic modes:
• Auto compass mode keeps the vessel on set heading
• NoDrift mode combines heading and position information, and keeps the vessel on a straight track
You toggle between Auto and NoDrift mode by repeated presses on the Auto key. The selection times out and triggers the mode shift. You can also confirm your selection by pressing the Starboard key or the rotary knob.
Autopilot modes | AP70 MK2 Operator Manual
Defining the heading/course change for the arrow keys
By default the set heading (Auto mode) and set course (NoDrift mode) will change 1° each time you press the port or starboard key. You can change this increment setting from the
Turn settings dialog. The dialog is activated from the Turn Quick menu and from the
Autopilot settings dialog.
The turn preset function
The system includes a turn preset feature for Auto and NoDrift mode. This allows for setting the new heading/course, turn radius and turn type before the turn starts. The function gives a more precise starting point for the turn, and it also avoids unintended heading/course changes when accidentally turning the rotary knob.
Ú Note: The port and starboard keys will always give immediate action, also when the turn preset function is active.
Enabling the turn preset function
Using the turn preset function
When in Auto or NoDrift mode:
1.

• Switch to AUTO mode by pressing the AUTO key. Repress the key to highlight the Auto option in the pop-up menu
When the mode is activated, the autopilot selects the current boat heading as the set heading.
Changing set heading in AUTO mode
You adjust the set heading by turning the rotary knob or by pressing the port or starboard keys.
An immediate heading change takes place. The new heading is maintained until a new heading is set.
Heading capture
When the vessel is turning in AUTO mode, an instant re-press on the AUTO key or the rotary knob activates the heading capture function. This will automatically cancel the turn, and the vessel will continue on the heading read from the compass the very moment you pressed the AUTO key or the rotary knob.
Temporary heading changes
If you need to avoid an obstacle when in AUTO mode, you can press the STBY key and power steer or use the helm until the obstacle is passed.
If you re-press the AUTO key within 3 minutes you can select to continue on previous set heading. If you don’t respond within 3 seconds the menu will disappear, and the autopilot will go to AUTO mode with current heading as set heading.
Quick menu in AUTO mode
From the Quick menu in AUTO mode you can change rudder parameters and set manual speed.
Autopilot modes | AP70 MK2 Operator Manual
NoDrift mode
Ú Note: It is not possible to select NoDrift mode if GPS position and heading information is missing.
In NoDrift mode the vessel is steered along a calculated track line, from present position and in a direction set by the user. If the vessel is drifting away from the track line due to current and/or wind ( A ), the vessel will follow the line with a crab angle.
A
• Switch to NoDrift mode by pressing the AUTO key. Repress the key to highlight the
NoDrift option in the pop-up menu
When the mode is activated, the autopilot will draw an invisible track line based on current heading from the vessel’s position.
The autopilot will now use the position information to calculate the cross track distance, and automatically steer along the calculated track.
Changing set course in NoDrift mode
You adjust the set course by turning the rotary knob or by pressing the port or starboard keys.
An immediate course change takes place. The new course is maintained until a new course is set.
Dodging
If you need to avoid an obstacle when using NoDrift mode, you can set the autopilot to
Standby mode and power steer or use the helm until the obstacle is passed.
If you return to NoDrift mode within 60 seconds you can select to continue on previous set bearing line.
If you do not respond, the dialog disappears and the autopilot goes to NoDrift mode with current heading as set bearing line.
Quick menu in NoDrift mode
From the Quick menu in NoDrift mode you can change the track response, rudder parameters and set manual speed.
Turn patterns
The system includes the following turn patterns:
• U-turn
• S-turns (optional)
Autopilot modes | AP70 MK2 Operator Manual 23

S-turns mode.
Turn variables:
• Course change
• Turn radius
S-turn settings
The S-turn settings can be set as default values.
24 Autopilot modes | AP70 MK2 Operator Manual
The default values can be changes at any time when the boat is in a turn.
NAV mode
Ú Note: NAV mode requires a compatible navigator connected to the network.
It is not possible to select NAV mode if heading information is missing, or if steering information is not received from the external chartplotter.
In NAV mode the autopilot uses steering information from an external navigator to direct the vessel to one specific waypoint location, or through a series of waypoints.
In NAV mode, the autopilot's heading sensor is used as heading source for course keeping.
Speed information is taken from SOG or from selected speed sensor. The steering information received from the external navigator alters the set course to direct the vessel to the destination waypoint.
To obtain satisfactory navigation steering, the autopilot system must have valid input from the navigator. Autosteering must be tested and determined satisfactory prior to entering
NAV mode.
Ú Note: If the navigator does not transmit a message with bearing to next waypoint, the autopilot will steer using Cross Track Error (XTE) only. In that case you must revert to
AUTO mode at each waypoint and manually change set course to equal bearing to next waypoint and then select NAV mode again.
Prior to entering NAV mode the navigator must be navigating a route or towards a waypoint.
• Initiate NAV mode by pressing the NAV key
• Confirm to switch to NAV mode in the dialog
Turning in NAV mode
When your vessel reaches a waypoint, the autopilot will give an audible warning and display a dialog with the new course information.
There is a user defined limit for the allowed automatic course change to next waypoint in a route. If the course change is more than this set limit, you are prompted to verify that the upcoming course change is acceptable.
• If the required course change to the next waypoint is less than the course change limit, the autopilot will automatically change the course. The dialog will disappear after 8 seconds unless cleared by the X key.
Autopilot modes | AP70 MK2 Operator Manual 25
• If the required course change to next waypoint is more than the set limit, you are prompted to verify that the upcoming course change is acceptable. If the turn is not accepted, the vessel will continue with the current set heading.
Course change less than set limit Course change larger than set limit
The course change limit setting depends on the autopilot computer:
• AC70: Course change limit
• SG05 PRO: Navigation change limit
Refer to
"Course change limit" on page 33.
Track offset
The track offset options allows for steering parallel to the track in NAV mode.
To activate the track offset option:
• press and hold the rotary knob
The display will change to show current distance from track, XTD ( A ) and set offset, OFF
( B )
Turn the rotary knob to adjust the offset distance. The blue line ( C ) shows the offset in relation to the track.
The system will remain in track offset mode for as long as there is an offset value. It will time out when the offset distance is set to 0 (zero).
Waypoint arrival circle
The arrival circle (radius) defines the point at which a turn is initiated when you are navigating a route.
The arrival circle is set in your chart plotter.
26 Autopilot modes | AP70 MK2 Operator Manual
The arrival circle ( 1 ) should be adjusted according to boat speed. The higher the speed, the wider the circle. The intention is to make the autopilot start the heading change in due time to make a smooth turn onto the next leg.
The figure below may be used to select the appropriate arrival circle when creating the route.
X axis = Boat speed in knots
Y axis = Arrival circle, radius in 1/100 Nm
Example: With the speed of 20 knots you should use a waypoint circle with radius 0.09 Nm.
Ú Note: The distance between any waypoints in a route must not be smaller than the radius of the arrival circle.
Quick menu in NAV mode
From the Quick menu in NAV mode you can change navigation response and set manual speed.
Controlling steering performance in automatic and navigational modes
The autopilot should be configured during installation and setup.
To increase steering performance, some parameters may be adjusted during operation. The parameters are available from the Quick menu.
Quick menu, Auto mode Quick menu, Nav and NoDrift mode
Track response
Defines how aggressively the autopilot should steer towards the active route's leg.
Rudder gain
This parameter determines the ratio between commanded rudder and the heading error.
The higher rudder gain value the more rudder is applied. If the value is too small it will take a long time to compensate for a heading error, and the autopilot will fail to keep a steady
Autopilot modes | AP70 MK2 Operator Manual 27
28 course. If the value is set too high the overshoot will increase and the steering will be unstable.
A
B
A The value is set too high. Steering becomes unstable and often the overshoot will increase
B The value is set too low. It will take a long time to compensate for a heading error, and the autopilot will fail to keep a steady course
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, inertia, hull shape and rudder efficiency.
• If the vessel has good dynamic stability, a relatively small value will be sufficient
• An unstable vessel will require high value
• The greater the vessel’s inertia, the greater value will be required
Increasing counter rudder value may result in some higher rudder activity also when steering a straight course, particularly in high waves.
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 B C
A Counter rudder value too low; overshoot response
B Counter rudder value is too high; sluggish and creeping response
C Correct setting of Counter rudder; ideal response
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 in illustration C .
Ú 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 creeping response to the other.
Speed
If neither boat speed nor SOG data are available and/or deemed unreliable, a manual value for speed can be entered and used by the autopilot to aid steering calculations.
Autopilot modes | AP70 MK2 Operator Manual
Simulator mode
The simulate option lets you operate the unit without being connected to sensors or other devices.
It is not possible to simulate commissioning and setup.
If the unit is turned off while in simulator mode, this mode will still be active on next power on.
Active simulator mode is indicated with a flashing notification on the image.

Work profiles
A work profile is a set of steering parameters. You can change the active work profile to adapt the autopilot steering characteristics to different operational conditions.
The AP70 MK2 has a set of predefined work profiles, depending on selected boat type. There can be up to 6 work profiles defined in the system.
During commissioning and seatrial the parameters for active profile will be tuned for optimized steering performance.
Predefined profiles
Normal profile
This is the default profile and automatically assigned when you set your vessel type to
Displacement .
It is recommended to use the Normal profile as a general profile for your vessel. This should be active during the commissioning of your vessel, and all parameter settings will then be saved to this profile.
High and Low profiles
High and Low profiles are automatically assigned when you set your vessel to Planing .
The system switches automatically between High and Low profiles based on the vessel's speed and the Transition speed setting. Refer to the separate Installation manual.
Creating a new work profile
New profiles can be defined for operational modes where the vessel’s steering parameters deviate from the default profiles.
You can also define a profile for easy access to preferred parameters for various crew members.
1.
Press the Work key to display the Work Quick menu
2.
Select the Add profile option
3.
Select a reference profile that matches the working conditions
- A new profile must be based on an existing or a predefined work profile. The parameters from the work profile you select as base will be copied to the new profile, and can later be edited
4.
- Edit the profile settings as required
5.
Complete the task by selecting the Add Profile option
30
User configurable settings
The steering parameters can be configured differently between the different profiles, depending on boat steering characteristics and user preferences.
The initial parameters are automatically assigned when you select your vessel type. During the seatrial the parameters will be tuned for optimized steering performance.
Work profiles | AP70 MK2 Operator Manual
The options listed in the next pages are available and can be manually adjusted for all profiles.
Auto steering
Turn
Used for selecting how you want to control the vessel’s 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
Turn rate
Used for manually setting the turn rate used when the heading change is larger than 5°.
Adaption
When this setting is activated, the autopilot will continuously adapt some steering related parameters to the vessel's behavior. The adapted parameters are stored in the work profile.
Rudder gain
This parameter determines the ratio between commanded rudder and the heading error.
The higher rudder gain value the more rudder is applied. If the value 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. If the value is set too high the overshoot will increase and the steering will be unstable.

Autotrim
Controls how fast the autopilot will apply rudder to compensate for a constant heading offset, e.g. when external forces such as wind or current affects the heading. Lower autotrim will give faster elimination of a constant heading offset
Work profiles | AP70 MK2 Operator Manual
Off heading limit
Sets the limit for the off heading alarm.
When the alarm option is activated an alarm occurs when the actual heading deviates from the set heading more than the selected limit.
Low speed limit
Sets the limit for the low vessel speed alarm.
An alarm occurs when the vessel’s speed goes below the selected limit.
Nav steering
Nav response
Defines how aggressively the autopilot should steer towards the active route's leg.
Approach angle
This setting is a limit to prevent approaching the track too steeply. Approaching the track at shallower angles is permitted depending on the cross track distance (XTD) and nav response setting.
This setting is used both when you start navigating and whenever the autopilot is working the boat towards the route.
Course change limit
Defines the limit for automatic course change to next waypoint in a route when the autopilot is following a route (NAV mode).
If the course change is greater than this set limit, you are prompted to verify that the upcoming course change is acceptable.
XTD limit
Defines the vessel’s accepted offset distance from the track. If the vessel goes beyond this limit an alarm will be activated.
Drive select
Defines which drives that shall be used for the selected work profile.
Rudder
Work profiles | AP70 MK2 Operator Manual 33
Init rudder
Defines how the system moves the rudder when switching from hand steering (Standby, FU and NFU) to an automatic mode.
The following options are available:
• Center
Moves the rudder to zero position
• Actual
Maintains the rudder angle, and assumes that the current rudder angle is the trim required to maintain a steady heading.
Rudder limit
Determines the dynamic range of the rudder before its movement is restricted and alarm is triggered. Typical usage is to limit the amount of rudder action caused by yawing in following sea.
Ú Note: Rudder limit is not a hard limitation of the rudder range, only around the current setpoint.
This Rudder limit does not affect Non-Follow-up or Follow Up steering.
Toe angle
This option sets the allowed angle deviation between the rudders. The feature will enhance rudder efficiency at small rudder commands around center position, and it will reduce vibration and/or propeller/water jet noise.
The toe angle is the angle between the rudder’s 0-position and the rudder’s actual position
(t) as shown in the illustration.
t t t t
The toe angle will be applied as an offset to each rudder. Toe out (positive value), angles the two rudders apart, while Toe in (negative value) angle them towards center.
Ú Note:
The toe angle is a work profile setting, and must be enabled for current work profile to be available.
The toe angle is only available if the vessel has 2 rudders. It applies only to rudders located on the side of the ship - it will have no effect on a rudder located in the ship center.
The toe angle is effecting all operating modes except Standby and NFU.
When the feature is enabled, one rudder will stop moving before the other one if max./ min. rudder angles are demanded.
When the feature is enabled, the rudder bar shows rudder command instead of measured rudder angle.
34 Work profiles | AP70 MK2 Operator Manual
Thruster
Deadband
Determines how many degrees the vessel must deviate from the set course before a thruster command is given. As the vessel deviates from its heading, the thruster will push the vessel back.
A higher value will reduce the thruster activity and extend the lifetime, especially for on/off thrusters.
Assist
Determines how the thrusters are used by the autopilot.
When set to ON, the thrusters will automatically be used by the autopilot system if the vessel speed is below inhibited limit. If the vessel speed is above inhibited thruster speed the thrusters will be turned off, but will automatically be turned on again when the speed goes below the inhibited limit.
Ú Note: Thruster inhibit speed is set during installation and is the max. vessel speed for which the thruster is allowed to run.
When set to OFF, thruster has to be manually enabled.
Push boat to
Used for specifying if the thruster should be used for course deviations to port only, starboard only, or for any course deviation.
Work profile name
Set the name to identify the profile.
Ú Note: You can use several characters for the profile name, but only the first 6 characters will be shown as profile name.
Profile icon
The system includes a number of icons that can be used to identify the profile settings.
Exporting and importing work profiles
It is possible to export and import a work profile to/from a USB stick.

The alert system
The system continuously checks for dangerous situations and system faults while running.
Responsibility transfer
The system does not support responsibility transfer.
Type of alerts
The system has different alert types:
• Alarms : This type of alert is activated when a situation occurs that might result in a collision, or for conditions that critically effect the capability or performance of the system.
An alarm is accompanied by an audible signal, and the alarm icon flashes until the alarm is acknowledged.
• Warnings : This type of alert announces conditions that could result in unwanted system response or eventual failure if no action is taken. A warning is accompanied by an audible signal (2 short signals, repeated as a Warning if not acknowledged). The warning icon flashes until the warning is acknowledged.
• Cautions : This is information about danger and caution objects that require attention.
Cautions have no audible signal.
Alert indication
When an alert situation occurs, a siren will sound and the alert icon will become active. The alert pop-up will show alert cause, followed by the name of the device that generated the alert.
A single alert is displayed with the name of the alert as the title, and with details for the alarm.
If more than one alert is activated simultaneously, the alert pop-up can display multiple alerts. The alerts are listed in the order they occur with the alert activated first at the top. The remaining alerts are available in the Active alerts dialog.
Alert icons
The alert icon will remain in the status panel until the alert is acknowledged and rectified.
The table below shows alert icon and behavior depending on if the alert is active, acknowledged, transferred or rectified.

Setting the alert and warning limits
Most autopilot alerts are activated based on pre-set alert limits, and these limits be changed by the user.
The following setting(s) are common for all work profiles. For work profile specific settings, refer to
Compass difference limit
When two compasses are used (main compass and monitor compass), there is almost always a difference between the readings of the two. If the difference exceeds the set limit, an alarm is given.
Ú Note: The difference between the two compass readings may vary with the vessel’s heading and from one area to another where a vessel is in transit. The difference between the two compass readings is automatically reset when a Compass difference alarm is acknowledged.
BAM bridging master
Select BAM bridging master on the unit that you want to do the alert handling and send the alert information to BAM through the SI80 NMEA0183 port.
For BAM bridging to work correctly, only one unit must be selected as BAM bridging master in Advanced system settings.

Fallback and failures during automatic steering
Rudder data missing
Alarm will be given, and steering will after 0.1 sec continue using virtual (estimated value based on known rudder speed) rudder angle data.
Steering compass missing
When monitor compass is available
Alarm for main compass failure is given and steering continues using monitor compass. If there is a difference between the compasses, a smooth transition (2 min. filter) to the monitor compass heading takes place. When acknowledging the alarm, the autopilot goes to
Standby mode.
When monitor compass is not available
Rudder is kept at fixed angle (i.e. heading is approximately maintained if failing when heading keeping, turn is approximately maintained if failing when turning), alarm is given and autopilot goes to Standby mode.
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, check heading
If there is an abnormal heading jump in steering compass heading, an alarm 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.
Boat speed missing
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 priority and fallback:

Maintenance
Preventive maintenance
The unit does not contain any field serviceable components. Therefore, the operator is required to perform only a very limited amount of preventative maintenance.
Cleaning the display unit
To clean the screen:
• A micro-fiber or a soft cotton cloth should be used to clean the screen. Use plenty of water to dissolve and take away salt remains. Crystallized salt, sand, dirt, etc. can scratch the protective coating if using a damp cloth. Use a light fresh water spray then wipe the unit dry with a micro-fiber or a soft cotton cloth. Do not apply pressure with the cloth.
To clean the housing:
• Use warm water with a dash of liquid dish soap or detergent.
Avoid using abrasive cleaning products or products containing solvents (acetone, mineral turpentine, etc.), acid, ammonia, or alcohol as they can damage the display and plastic housing.
Do not:
• use a jet or high pressure wash
Cleaning the media port door
Clean the media port door regularly to avoid salt crystallization on the surface, causing water to leak into the card slot.
Checking the connectors
Push the connector plugs into the connector. If the connector plugs are equipped with a lock or a position key, ensure that it is in the correct position.
