General Information
1 GENERAL INFORMATION
1.1 Introduction
The AP50 system is produced and tested in accordance with the
European Marine Equipment Directive 96/98. This means that
the AP50 complies 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 AP50 may be installed on vessels not needing to
comply with the Marine Equipment Directive, those requiring
compliance must have one AP50 Control Unit set-up as a
“master unit” in order for the installation to be approved. Simrad
has no responsibility for the incorrect installation or use of the
AP50 autopilot, 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 and use.
The purpose of the Marine Equipment Directive is to enhance
safety at sea and to prevent marine pollution through the
uniform application of the relevant international instruments
relating to equipment listed in Annex A1.
As there are many interfacing requirements in the
standards/codes, integrated systems and integrated certification
lead to more efficient and effective management of safety,
environmental, issues and quality.
The Marine Equipment Directive also constitutes a part of the
International Safety Management (ISM) Code. The ISM Code
was included as a new chapter (IX) of SOLAS in 1994, and is
mandatory for: passenger ships not later than 1st of July, 1998;
oil tankers; chemical tankers; gas carriers; bulk carriers and
cargo high speed craft of 500 gross tonnage and upwards not
later than 1st of July, 1998; and other cargo ships and mobile
offshore drilling units of 500 gross tonnage and upwards not
later than 1st of July, 2002.

Simrad AP50 Autopilot
It is required that both the shipping company and ships shall be
certified by the Administration (the government of the state
whose flag the ship is entitled to fly), by an organization
recognized by the Administration or by the government of the
country acting on behalf of the Administration.
1.2 How to Use This Manual
This manual is intended as a reference guide for installing and
commissioning the Simrad AP50 autopilot. Great care has been
taken to simplify the set-up and operation and of the AP50;
however, an autopilot is a complex electronic system. It is
affected by sea conditions, speed of the vessel, and vessel hull
shape and size.
Please take the time to study the manual carefully together with
the Operator Manual to get a thorough understanding of the
autopilot system components and their relationship in a
complete AP50 autopilot system.
Particularly when setting up and commissioning the system it is
important to have both manuals at hand.
At the end of this manual, you will find an index and a glossary,
which will help you when studying the manual.
Copies of approval certificates are included in the last section
(8) of this manual.

2 INSTALLATION
2.1 General
This section provides detailed information required to properly
install the AP50 Autopilot system.
The AP50 system includes 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 (NMEA interfacing)
In addition, the advanced capabilities of the AP50 require the
installer to perform a series of settings and tests to verify proper
operation of the system (refer to the Installation Index below).
2.2 Unpacking and Handling
Care should be taken when unpacking and handling the
equipment. A visual inspection should be made to ensure that
the equipment has not been damaged during shipment and that
all parts are present according to the packing list.
A standard scope of supply for a basic AP50 system may
include:
• A control unit with standard installation accessories
• A junction unit (J50, J50-40) and one 15 m (49 ft.) Robnet
cable
• An RC25 Rate Compass with one 15 m (49 ft.) cable attached
• An RF300 Feedback unit with one 10 m (33 ft.) cable
attached and a transmission rod
• An appropriate drive unit for the installation (unless the AP50
is going to operate an existing drive unit)
• Any optional equipment that may have been ordered for the
installation

20222469 / B
Installation
Pay particular attention to the junction unit/drive unit
combinations on page 21 and the cable length and number of
Robnet units on page 27. Also refer to Junction Units in the
AP50 Operator manual.
As many of the units are communicating on a common network
(Robnet) with identical connectors, the installation is simplified.
Mount the units within the standard cable length supplied with
each unit, if possible (refer to Technical Specifications, section
4, beginning on page 91. Robnet Extension Cable (10m) is
available from your Simrad distributor. Refer to the Spare Parts
List on page 91 for part numbers.

2.6 RF300 Rudder Feedback Unit
(For small to medium size vessels)
The RF300 Rudder feedback unit mounts close to the rudders,
and is mechanically linked to the rudder tiller arm or rudder
quadrant (refer to Figure 2-2 on page 7 for the recommended
mounting arrangement). Note that the RF300 transmitter arm
has two slots for the transmission link. The slots enable
maximum flexibility to provide the 1:1 mechanical linkage
relationship.
Note !
Do not try to remove the transmitter arm from the feedback unit.
The unit is factory-adjusted and needs no further adjustment at
installation than that described below.
As a starting point, it is desirable to set the transmitter rod to the
inner limit of the outer slot if possible (refer to Figure 2-2). Drill
and tap the rudder tiller arm so that the Y1 dimension is equal to
the Y2 dimension (Use 4.2 mm drill and 5 mm tap). Attach the
ball joint to the tiller arm and connect the transmitter rod to the
ball joint at the rudder tiller arm.
Turn the helm to set the rudder tiller arm to the approximate
center position.
Rotate the RF300 transmitter lever until it is set to center
position (use the alignment mark to line-up the transmitter lever
to be opposite the cable entry into the feedback unit).
Note !
Carefully observe the alignment marks. A rudder feedback
alarm may result if the alignment instructions (as per Figure
2-2) are neglected.
Attach the transmitter rod to the RF300. Mount the RF300
Rudder Feedback Unit in accordance with Figure 2-2. The
center of the RF300 should be in line with the center of the
rudderpost. Mount the RF300 to a suitable platform using the
screws provided. If necessary, add blocking material under the
RF300 to adjust the height of the transmission arm to be level
with the rudder tiller arm.

Installation
Figure 2-2 RF300 Rudder Feedback Unit Mounting (019356)
Note !
Due to space limitations, it may be necessary to cut the length of
the transmitter rod to move the RF300 closer to the rudderpost.
Tighten the mounting screws for both the RF300 Rudder
Feedback Unit and the transmitter rod ball joint.
Observe the RF300 unit while someone else turns the helm
wheel through the complete travel from full port to full
starboard rudder to verify that the mechanical linkage to the
RF300 is not obstructed.
Connect the RF300 to the J50 Junction Unit as shown in Figure
2-3.

2.7 RF45X Rudder Feedback Unit
(For medium to large size vessels)
The RF45X Rudder Feedback Unit is normally installed with the
shaft pointing upwards. However, it can be mounted with the
shaft pointing downwards for increased convenience. The
deflection can then be inverted in the AP50 software or as
illustrated in Figure 2-5 on page 9. An “upside-down” installation
will make access to the unit more efficient as it can be opened
without moving it from the mounting base. To open the unit,
unscrew the two screws of the unit and remove the cover. Be
careful not to damage the wires when you replace the cover.
Max 600mm (23,5")
Figure 2-4 RF45X Rudder Feedback Unit Mounting
Use the enclosed template (Drawing 22011225) to drill the
required mounting holes. The unit is fastened to the mounting
base by the two Allen screws enclosed (other types of screws may
be used if it is to be fastened to another type of base, i.e. a
wooden base).
Make the parallelogram configuration of the transmission link
(see Figure 2-4) and temporarily fasten the link to the RF45X
shaft. The transmission rod can be shortened by cutting off a
piece using a hacksaw. Move the rudder manually hard over to
hard over and make sure the transmission link is moving freely in
both directions.

20222469 / B
Installation
Electrical Connection
Use a twisted-pair shielded cable, 0.5 mm2 (AWG20), between
the breakout box and the J50 Junction Unit. The cable length is
not critical but should be kept to a minimum.
The cable should be connected to the junction unit according to
Figure 2-5. When splicing the cables in the breakout box, crimp
the enclosed pins on each wire of the extension cable to avoid
cutting off the wires at the terminal point when the screws are
tightened.
The screen must be connected in the junction unit.
Note !
The green and yellow wires are not used and must be isolated!
For final alignment, see page 11.

The above connection diagram shows how to connect an RI9
Rudder Angle Indicator to a system with RF45X Rudder
Feedback Unit. For connection of RI35 Mk2 Rudder Angle
Indicators only, refer to the RI35 Mk2 manual.
This connection gives full functioning indicator(s) also with the
autopilot switched off. To have the indicator(s) switched off
with the autopilot; connect indicator(s) and rudder feedback
supply+ to J50 Vbat+ instead of J50 Supply+.
Note !

2.8 RF14XU Rudder Feedback Unit
Mechanical mounting
Before installation, check that the alignment mark on the
mounting plate agrees with the mark on the shaft. Bring the
rudder to Midships position. The feedback unit should be
mounted on a plane surface and secured by bolts through the
three holes in the mounting plate. It should be linked to the
rudder in accordance with Figure 2-7. It is important that the
linkage is linear, i.e. the A-a and D-d are pairs of equal length.
This will give a ratio 1:1 between the rudder angle and that of
the feedback unit shaft. Final adjustment is made by loosen the
fixing screws for the potentiometer, and carefully turn the
potentiometer for correct positioning.
Note !
If the RF14XU is mounted with the shaft pointing upwards, the
yellow and the blue lead to the potentiometer inside must be
interchanged (See Figure 2-9).
Figure 2-7 RF14XU - Mounting
Electrical installation
The cables are carried through cable glands. If required, to avoid
any mechanical damage, the cables should be run in a conduit
between the rudder feedback unit and the junction unit or rudder
angle indicator. Electrical connection is shown in the cabling
diagram. The cable screen must be connected to the internal
ground terminal. Ref. Figure 2-8.
12
20222469 / B
Installation
The feedback unit has an external ground terminal an must have
a proper ground connection to the hull. The grounding wire
should be as short as possible and at least 10 mm wide.
The RF14XU can be powered either from the rudder angle
indicator supply (19-40V DC) or directly from the autopilot
junction unit. If a rudder angle indicator is connected, the
RF14XU is powered from the rudder angle indicator supply. If
the rudder angle indicator voltage disappears, or rudder angle
indicator is not connected to the RF14XU, the feedback unit is
powered directly from the autopilot. The change over is done
automatically.
Note !
If RF14XU is connected to rudder angle indicators, and the
indicators are powered from an unfiltered 24V supply, the
enclosed 470uF capacitor should be connected across the
supply. Without the capacitor, a deviation may occur between

20222469 / B
Installation
The RI9 Rudder Angle Indicator is connected to the U-terminal
on RF14XU, while RI35 Mk2 Rudder Angle Indicator is
connected in parallel with the feedback signal for the junction
unit. Use the same supply for RI35 Mk2 as for the autopilot.
The connection shown below gives full functioning indicator(s)
also with the autopilot switched off. To have the indicator(s)
switched off with the autopilot, connect indicator(s) and rudder
feedback supply+ to J50 Vbat+ instead of J50 Supply+.
Note !
This configuration is only for 24VDC.

Final check
After installation, the cable glands must be sealed with silicon to
prevent water from seeping in. Also apply silicon grease to the
gasket between the bottom and top cover.
On the inside of the feedback unit cover, a piece of moisture
protecting sponge is attached. The sponge produces a corrosion
preventive gas, and to increase the efficiency of the gas the
cover must be kept tight.
2.9 J50 Junction Unit
The J50 Junction Unit is designed to operate in a location that
provides ambient temperatures below +55°C (+130°F).
Note !
The junction units (J50 and J50-40) are not waterproof and
should be mounted vertically, as shown in Figure 2-11, in a dry
place between the control unit and the drive unit.
Figure 2-11 J50 Junction Unit Mounting
Cable Connections
Use only shielded cables. This includes Mains input, drive units,
and, if necessary, for the extension of the RF300 Rudder
Feedback Unit cable. The clutch/bypass cable and the solenoid
cable should be 1.5 mm2 (AWG14). Signal cables should be 0.5
mm2 (AWG20) twisted-pairs.
The Mains supply cable and the drive unit motor cable should
have sufficient wire gauge. This will minimize voltage drop and
allow the drive unit to operate at full power.

Grounding and Radio Frequency Interface
(RFI)
The AP50 system has excellent radio frequency interference
protection and all units use the junction unit as a common
ground/shield connection. The junction unit must therefore have
a proper ground connection to the hull.
Robnet 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.
Note!
The Mains input
is not polarity
protected on the
J50-40.

Main Board Terminals
System Select
The “System select” (Sys. Sel.) input signal of the J50 can be used
to alternate between the boat’s own steering and the autopilot
system from an external system selector (refer to IMO resolution
MSC. 64 sec. 4). A ground on TB14 Sys. Sel. will force the
system into Disengage mode. The autopilot will be disconnected
from the vessel’s steering system and show “Disengaged” on the
display (on the FU50, no mode indicators will be lit). When the
“Sys. Sel.” input line is re-opened, the autopilot will go to AUTO
mode. For wheelmark installation (Master operation = Yes, ref.
page 49) the master control unit will be active.
18
20222469 / B
Installation
For non-wheelmark installations the autopilot will continue on the
present heading, but no course change can be made before a
control unit is activated again by pressing the AUTO button.
Autopilot Mode Control (AUTO/STANDBY
Toggling)
The Port/stbd lines of the J50 Remote terminal can be used to
alternate between automatic and electric hand-steering from the
autopilot. This may be used for armrest operation, etc. When in
AUTO mode or NAV mode, a simultaneous pulse from the Port
and Stbd terminals to the ground terminal on the remote
connection will revert the autopilot to STANDBY mode. The
next pulse will bring the autopilot to AUTO mode, hence, when
the AP50 is set for STBY (NFU) and the system select is shorted
to GND, the AP50 display changes from showing STBY to show
a blank segment with subtext “Disengaged”. In this mode all
rudder commands from the AP50 are disabled (no NFU, FU or
Auto).
When the short is removed, the display will show “AUTO” with
subtext “Inactive”. This means that the preset heading will be
maintained, but no course change can be made before the
respective control unit is activated by pressing the AUTO button.
External Alarm (Non Wheelmark System)
The external alarm circuit has an open collector output for an
external alarm relay or buzzer. The alarm voltage is the same as
the main supply voltage. The maximum load on the external
alarm output is 0.75 ampere.
Figure 2-13 External Alarm Connections (Non Wheelmark System)
20222469 / B

Simrad AP50 Autopilot
External Alarm (Wheelmark System)
Note !
Wheelmark installation requires separate monitoring of power
failure.
Note that Simrad does not supply an external alarm unit,
required for a Wheelmark system. The diagram below shows
how an arrangement can be made. The buzzer shall provide
between 75 and 85 dB of power.
The relay voltages are determined by the autopilot Mains supply
and the alarm voltage supply.
Figure 2-14 External Alarm Connections (Wheelmark System)
2.10 Drive Unit Installation
The relation between drive units, drive unit voltage, input
voltage, drive output, and interfacing to steering gear are shown
in Table 2-2 and Table 2-3. The AP50 system detects whether a
reversible motor or a solenoid is connected and outputs the
correct drive signal automatically.
Refer to the connecting diagrams for the different drive units on
pages 22 through 24.
Installation instructions for the drive units are found in the
manuals for the individual units.
The maximum drive current capabilities of the J50 and J50-40
Junction Units are different. Use the table below as a reference
and observe the notes.

set equal to the motor voltage. In a retrofit installation where,
for example a HLD2000 has a 12V motor and a 24V bypass
valve, the bypass valve solenoid has to be changed back to
standard 12V version since the drive engage output voltage
follows the motor voltage setting.

2.11 Control Unit
Avoid mounting the control unit(s) where it is easily exposed to
sunlight, as this will shorten the lifetime of the display. If this is
not possible, make sure the units are always covered with the
protective cover when not in use.
Panel-mounting
The mounting surface must be flat and even to within 0.5 mm.
• Drill the 4 mounting holes and
make a panel cutout according to
the supplied template.
• Use the supplied gasket between
the panel and the unit.
• Use the supplied 19 mm screws to
fasten the control unit to the panel.
Gasket
• Apply the front panel corners.
• Connect the Robnet cable(s) to the

Optional Bracket mounting
(This may be ordered separately from Simrad, part no.
20212130).
Note !
When the control unit is bracket-mounted, it is not weatherproof
from the back due to a breathing hole in the back cabinet. When
bracket-mounted, the exposed parts of the plugs should be
protected against salt corrosion.
• Locate the cradle on the mounting site and mark the 4 holes
for the screws on the mounting surface.
• Drill the 4 holes and screw the cradle to the mounting
surface.
• Use the supplied screws to fasten the control unit to the left

Robnet Units and Robnet Network Cables
The following Robnet units are available in a system:
AP50 Control Unit, AP51 Remote Control, RC25 Rate
Compass, FU50 Follow-Up lever, GI51 Gyro Interface, NI300X
NMEA Interface, TI51 Thruster Interface and AD50 Analog
Drive.
As most Robnet units have two Robnet connectors, they can be
used for further expansion of the system. There are no dedicated
"in" or "out" connectors. You may connect the cables to any
available Robnet connector on the specific unit.
The Robnet cables are available in 7 and 15 m lengths and they
contain a 6-pin male connector at one or both ends. The 15 m
cable to the junction unit has a connector only at the control unit
end.
Additional extension cable (10 m) with a male and a female
connector, is available from Simrad (part no. 22192266).
When installing a system, try to minimize the total Robnet cable
length by connecting all Robnet units to the nearest available
Robnet connector.
The total length of Robnet cables depends on the number of
Robnet units and the voltage drop across the connected units.

AP51 Remote Control Connection
If the AP51 Remote Control is part of the system, use the
Robnet connector in a free receptacle (see Figure 2-21).
Alternatively, cut the connector from the cable and connect the
wires in parallel with the cable shown on Figure 2-23 using the
same color code.
Note !
The AP51 cable contains a ventilation tube. Check that the tube
is open after you have cut the cable.
AP51 in a Wheelmark System
In a Wheelmark system, only the Master Unit may turn the
system off. To ensure that the system cannot be switched on or
off from the AP51 Remote Control Unit, the yellow wire in the
AP51 cable must be cut or not connected. Open the Robnet
connector (see Figure 2-22). Remove pin 3 (yellow wire) and cut
it off at the end of the wire. Insulate the wire and push it back in
the pin 3 slot. Reassemble the Robnet connector.
JP21 Jack Point Installation
The JP21 Jack Point can be used in conjunction with the AP51
Remote Control Unit.
It provides a quick and simple means of connection and
disconnection of the AP51 at different locations on the boat.
The JP21 includes a watertight connector cover that must be
installed as shown below. A 32 mm (1.26 inch diameter) hole
must be drilled for flush installation, along with 3 small screw
holes. As indicated, a watertight sealant must be applied to the
mating surfaces of the JP21 and the mounting panel. Apply a
thin layer of Vaseline to the O-ring seal.

2.12 RC25 Rate Compass
Figure 2-25 RC25 Rate Compass Mounting
The heading sensor is the most important part of the AP50
system and great care must be taken in choosing the mounting
location. The heading sensor can be mounted at any location
where there is a minimum of magnetic interference and
minimum movements. It is not recommended to use the RC25
on steel vessels. However, if this is done, it should be installed 1
meter above the steel deck to obtain optimum performance.
Note !
In order to prevent excessive movements, an autopilot heading
sensor should not be installed on the fly bridge or on the mast.
The rate compass can be deck-mounted or on the bulkhead,
athwartship or alongship. The heading offset feature of the
AP50 will compensate for the mechanical offsets that may be a
result of the selected location and orientation of the RC25.
30
20222469 / B
Installation
If the compass is deck-mounted or bulkhead-mounted
athwartship with the cable gland pointing aft, little if any offset
correction is required. When the cable gland points forward, a
180° correction is required.
When mounting the compass on a bulkhead alongship, a +90° or
-90° correction is needed, dependent on whether it is a port or
starboard bulkhead.
Select a location that provides a solid mounting place free from
vibration as close to the vessel's center of roll and pitch as
possible (i.e. close to the water line). It should be as far as
possible from disturbing magnetic influences, such as the
engines (minimum of 2 m), the engine ignition cables, the airconditioning, any refrigerators, other large metal objects, and
particularly the drive unit.
Use the supplied mounting kit and drill the holes through the
center of the slots in the sensor or the mounting brackets.
Note !
The compass faceplate on the rate compass is the TOP. NEVER
mount it upside down! Level the sensor as close to horizontal as
possible.

continuous voltage, or Danfoss PVEM valve signal.
Refer to separate manual for the AD50 Analog Drive.
2.16 S9 Steering Lever
Mounting
Refer to Figure 2-29. For bulkhead mounting, use the 8 bushings
enclosed with the unit. These are placed two and two against
each other and the screws are put through them. Direct contact
between S9 and a steel bulkhead is then avoided and corrosion is
prevented. The cover plate can be turned 360 degrees for the
most convenient position of cable outlet. For panel mounting
use the two mounting brackets enclosed with the unit (Figure
2-30).

Installation
The NI300X NMEA Interface (expansion) Unit is designed for
installations in which more NMEA lines have to be tied into the
system. Four NMEA ports, which are identical in hardware and
software, are available and can be connected as desired. An
additional output data-port with a DATA/CLOCK signal is
capable of generating heading data in the format used by some
radar displays made by Simrad and Furuno.
The 12V output is designed for driving instruments with a total
maximum load of 250 mA.
Configuration for Simrad or Furuno is selected in the
Installation Interface Menu (see page 61).
CD100A Course Detector
The owner may prefer to use the boat’s own compass. The
compass must be fully gimbaled and have a flat surface
underneath to fit the CD100A. Make a hole for a 6 mm screw in
the bottom of the compass and mount the CD100A as shown in
Figure 2-44. Secure the 6 mm screw through the center hole of
the CD100A. Make sure the cable does not prevent the compass
from moving freely in the gimbals.

Software Set-up Procedure
3 SOFTWARE SET-UP PROCEDURE
3.1 Description of Installation Set-up
The design of the AP50 includes advanced features that have
simplified the installation and set-up of an autopilot. The
principle advantage is that the manual adjustments that needed
to be made on previous models are no longer necessary with the
AP50.
The Installation Set-up must be performed as part of the
installation of the AP50 system. Failure to correctly set the
values in the Installation Set-up menu may prohibit the AP50
from functioning properly!
Note !
The Installation Set-up is grouped into the following functional
categories:
Selects the language used for display
• Language:
information.
Sets the values for items to be set prior
• Dockside
to sea trials.
Settings:
Sets the identification of navigation
• Interface Set-up:
equipment and optional equipment
connected to the AP50 system.
• Sea-trial Settings: Determines the automatic calibrations
and the steering parameters and sets the
compass offset.
Used to view system parameters,
• Service:
perform NMEA tests, and Master reset
system memories.
Setting or changing steering and
• Settings:
thruster parameters.
Each category is designed to focus on specific functions related
to an installation activity and to enable quick access when
changes need to be made.
SETUP
REQUIRED
RUDDER
02
Some important points regarding the Installation Set-up
values:
• When the AP50 is delivered new from the factory, (AND
ANY TIME AFTER A MASTER RESET OF MEMORIES
HAS BEEN PERFORMED), the Installation Set-up values
are all reset to preset (default) values. The warning message
"Setup Required" will appear at “turn on” and if an attempt
to access the AUTO or NAV modes is made.
• The Dockside and Interface settings can only be accessed
when the system is in Standby mode.
• The values that are selected in the Installation Menu are
20222469 / B
45
Simrad AP50 Autopilot
stored in the memory of the AP50 system. No specific action
is required to save the selected values to memory. Once the
value is changed, it is stored until the next time the menu
item is selected and changed.
• The Installation Set-up is considered global (except
language), which enables the values to be available to all
control units in the system.
• The values in the Seatrial Settings are dependent on the
successful completion of the Dockside Settings.
• In the table on page 89 the range of each setting is listed.
Note the final value selected during the Installation Set-up,
and also note any changes of values.
2
Before attempting to turn on the AP50 and perform an
Installation Set-up, the hardware installation and electrical
installation must be completed and performed in accordance
with the installation instructions.
3.2 Installation Menu
A single press on the (STBY) button switches the system on.
After approximately 5 seconds, the unit that was turned on will
show the Standby mode display. When the AP50 is delivered
new from the factory (and any time after a master reset of
memories has been performed), the Installation Set-up values are
all reset to preset (default) values. The warning message "Setup
Required" will appear at “turn on” and if an attempt to access the
AUTO or NAV modes is made.

This menu option requires the installer to set the reversible
motor Drive unit voltage to the correct level. The selections are
12V, 24V, or 32V and should be set to the voltage specified for
your drive unit. Drive engage/bypass clutch output follows the
same voltage as set for the drive unit. This also applies if Drive
engage is set to Auto or Handshake 1 (ref. page 80). It is not
possible to select a higher voltage than the input voltage.
Selection of an improper voltage level for your drive unit may
damage both the drive unit and junction unit, even if the
protection circuits in the junction unit are activated.
This setting does not apply for solenoid operated pumps ( ref.
49
Simrad AP50 Autopilot
Rudder Test, page 51). The solenoid voltage will always be
equal to the supply voltage.
Refer to the drive unit tables on pages 20 and 21 for
information. The clutch/bypass voltage is automatically set to
coincide with the drive unit voltage. During the rudder test, the
AP50 system will also automatically detect whether the drive
unit is a reversible motor or whether it is solenoid operated.
To change the voltage selection, rotate the course knob.
Note !
The Drive unit voltage setting does not apply when operating
solenoids on a continuous running pump/steering gear. Hence,
the output voltage to the solenoids will be the same as the input
voltage.

Make sure the rudder feedback unit is installed and aligned as pr.
instructions in section 2.6 (RF300), 2.7 (RF45X) or 2.8
(RF14XU) before attempting the Rudder feedback calibration.
This function enables you to compensate for non-linearity in the
mechanical transmission between the rudder and the rudder
feedback unit.
Select Rudder feedback calibration STBD by turning the
course knob clockwise. “Turn Rudder max STBD” will be
displayed on the screen.
Manually turn the helm wheel to starboard until the rudder stops
at maximum starboard rudder.
The value shown on the display is the value read by the feedback
unit before any adjustment is made. The bargraph indicates to
which side the rudder is positioned. Be sure to set the correct
rudder angle and direction by turning the course knob. The
autopilot uses this value as physical stop. Physical stop minus 2°
will be used as “max. rudder limit” and determines how far the
autopilot can under any circumstance, drive the rudder.
If the rudder feedback unit is mounted upside down, the
displayed rudder angle may be to the opposite side before you
start the adjustment (arrow pointing to Port). In this case, turn
the course knob starboard until the rudder angle indicator
displays the correct starboard value.
Advance to the next step by pressing the
50
(STBD) button.
20222469 / B
Software Set-up Procedure
Manually turn the helm wheel to port until the rudder stops at
maximum port rudder.
Adjust the displayed angle the same way as for starboard
adjustment (if the rudder feedback unit is upside down, you need
not correct for the opposite side this time).
Note !
If no adjustment has been made to the display readout (i.e. not
turning the course knob), the AP50 will set the physical stop to
45°. “Max. rudder limit” will be set to 2° less.
Note !
Rudder-zero may still be inaccurate and should be adjusted
later during sea trial.
Proceed to the next menu item (Rudder Test) by pressing the
(STBD) button.
Rudder Calibration

direction, detects minimum voltage for running, and reduce the
rudder speed (reversing pumpset or proportional valves) if it
exceeds the maximum acceptable speed for autopilot operation.
The Rudder test is verified by the display showing ‘Motor OK’,
‘Proportional OK’, ‘Solenoids OK’, or ‘Failed’. If ‘Failed’ is
given, check for correct electrical connection and also make sure
that the steering engine is selected for autopilot control (ref. to
‘System select’ on page 18).
When test is finished the display will read:

Rudder Limit determines the maximum rudder movement in
degrees from the “used” midship position that the autopilot can
command the rudder in the automatic modes.
“Used” midship position is the rudder angle required to maintain
a straight course.
The Rudder limit setting is only active during autosteering on
straight courses, NOT during course changes. This Rudder limit
does not affect WORK, Non-Follow-up or Follow Up steering.
In WORK, Non-Follow-up or Follow Up steering, only the max.
rudder limit applies.
Note !
The max. rudder limit was set automatically to physical stop
minus 2° when the rudder feedback calibration was performed.
Range:
5° to max. rudder limit in 1° steps.
Default: 10°

Necessary deadband to avoid the rudder from hunting is
calculated and set automatically during the rudder test. Therefore
this parameter should normally not be adjusted. If the autosetting does not perform properly (rudder commands due to
vibration of the rudder when under way), it can be adjusted
manually. A narrow deadband may cause the rudder to hunt and
a wide deadband will create inaccurate steering.
Adjust the Rudder deadband by rotating the course knob. Find
the lowest possible value that will prevent the rudder from
hunting. It is recommended to check rudder stability and
accuracy in FU-mode.

Interface Set-up
The AP50 system provides a flexible approach to the input of
data from heading sensors and other external equipment.
Identification of the type of equipment connected to the AP50
system is performed in the Interface Menu.
To be able to display all the information on the instrument
screens (see section “Instrument Screens and Menu” in the
Operator Manual), refer to the table in section 6.18 on page 110
for the required NMEA sentences.

20222469 / B
Software Set-up Procedure
When your system includes connection of external equipment to
the NMEA0183 data ports in the junction unit or the NI300X
NMEA Interface, or if the GI51 Gyro Interface is installed with
optional compass units, they must be configured in the Interface
Menu. This procedure allows you to assign an abbreviated name
to identify the type of equipment that is connected to each of the
available hardware ports in the AP50 system.
Caution !
The ECS1 and ECS2 set-up items are intended for connection
to professional navigators where the radius for the course
change is preset in the chart system. This turn radius will
allow the ship to turn before the waypoint is reached and
enables the AP50 to follow a route seamlessly.
Note !
Confirmation for course change by the user will not be required.
Users navigating in this mode must show extra caution!
When connecting a GPS or a Chartplotter, use the GPS1 or
GPS2 set-up item.

Sea Trial
Caution !
The Sea Trial must always be performed in open waters at a
safe distance from other traffic.
A sea-trial can only be performed if the Dockside Settings are
completed and confirmed. It is also important that the Interface
Set-up be performed prior to adjusting sea trial settings.
The following sea trial settings must be set:
• Compass calibration (to automatically compensate for
onboard magnetic deviation)
• Compass Offset (to offset the final compass heading readout)
• Max/Minimum thrust, thrust direction and levels (only if
thruster is selected)
• Set cruising speed (in the AP50)
• Set rudder zero (to indicate the precise midships position of
the rudder)
• Set rate of turn at cruising speed (to select your preferred turn
rate). It is essential that this setting is carried out.
If the boat steers satisfactorily, there is no need to perform the
Manual or Automatic tuning.
The following sea trial settings may be used as optional settings:
• Manual tuning (Steering parameters: Rudder, Counter
Rudder)
• Automatic tuning (an optional method of determining the
steering parameters)
• Speed response (to tell how the rudder gain shall be adjusted
automatically by vessel speed)

Compass Offset
The compass Offset feature allows you to correct for a constant
compass heading offset. This offset may be present as a result of
the compass being installed with a lubber line offset or if a fixed
offset remains after the calibration procedure has been
completed. The value of compass offset is specific to the

The Offset value can be either positive or negative.
If an Offset still exists after having accounted for it, one of the
following problems may still exist:
• The heading reference to which you are comparing the
compass is not accurate.
• The automatic calibration obtained by the compass is not
correct. This may be due to a large magnetic influence near
the compass (relocation may be required) or to excessive
wave condition during calibration.

Manual Tuning
If the boat steers satisfactorily, there is no need to perform the
Manual or Automatic tuning.
The two most important parameters that determine the
performance of the automatic steering are Rudder and Counter
Rudder.
These parameters have already been automatically set in the
Installation Dockside menu as scaling factors of the boat type
and boat length.
These settings may also be accessed at any time in the User Setup menu (see Operator Manual) under the automatic modes.

Automatic tuning
If the boat steers satisfactorily, there is no need to perform the
Automatic tuning.
Automatic tuning is a feature that automatically sets the two
main steering parameters (Rudder and Counter Rudder) by
taking the boat through a number of S-turns.
70
20222469 / B
Software Set-up Procedure
Selecting the boat type and length has set default values for
these parameters (Installation Dockside menu). Before doing
any parameter tuning, check if the boat steers satisfactory with
the default setting (can be checked as described under Manual
Tuning or by normal Auto steering).
Recommended speed during Automatic tuning varies with the
type of boat, but it should not exceed 10 knots.
Note !
Automatic tuning should not be performed at planing speed!
For displacement boats, use a speed that is approximately half
the normal cruising speed (i.e. if cruising speed is 10 knots, do
the Automatic tuning at about 5 knots).
If possible, perform the Automatic tuning steering East or
West, as this will yield the best-balanced parameters.
WARNING !
The Automatic tuning function will take control of the boat
and perform a number of S-turns. It must always be
performed in open waters at a safe distance from other
traffic. The Automatic tuning function may take from 1 to 2
minutes to complete. To stop the Automatic tuning, press the

Drive engage
This determines the use of the J50 Drive Engage port. The port
voltage is the same as the selected Drive Unit voltage. Drive
engage has the following different settings:
Bypass/clutch:
This port will activate (go high), in all modes except for
STANDBY and DODGE hand-steering.
It is typically used to engage a bypass valve for a hydraulic
linear drive. It may be used to start a hydraulic pump when
entering Follow-up, Non-Follow-up, AUTO and NAV. modes.
Auto:
The port will activate (go high) in AUTO and NAV modes.
"Auto On" is typically used to switch the pump speed when
different rudder speeds are needed in automatic and Followup/Non-Follow-up steering. The switch is normally off.
Handshake 1:
This setting is specially made for interfacing with KaMeWa's
CanMan standardized system but can also be used for similar
installations. Manual steering is performed from a joystick. On
top of the joystick, there is an override button for manual
takeover from the autopilot. The Drive Engage and Remote port
(regardless which one) of J50 is used as handshake signals
between autopilot and manual steering system as follows:
If AUTO, NAV or FU is selected, the Drive Engage port will go
high causing the autopilot to take control. When STBY is
pushed on the autopilot, Drive Engage will go low and the
manual steering system will take control. If the override button
is activated in AUTO or NAV, the pilot will go into STBY but
Drive Engage remains high, and the boat can be steered
manually by the joystick. When the override button is released,
the autopilot will take control again under new current heading
(AUTO) or ongoing track (NAV). Pushing the override button
in FU-mode will be identical to pushing the STBY button, i.e.
Drive Engage goes low and pilot remains in STBY.
NFU and Dodge from autopilot will not be possible when

The W Rudder limit setting is only active during AUTOWORK and NAV-WORK steering on straight courses, NOT
on course changes, but a Rudder Limit warning will be
shown during course changes.

Transition Speed
(Only appears in the Settings menu when “Planing” or
“Waterjet” is selected as the “Boat type”.
To make this adjustment you need speed input from either SOG
or Log.
Planing boats may often have very different steering
characteristics before and after planing. The same may apply for
water jet driven boats at low and high speed. AP50 offers the
possibility of using the Auto-Work mode values for Rudder and
Counter Rudder at low speed. By setting the Transition Speed
to a value different from the default = 0, the Work parameters
for Rudder, Counter Rudder and RateOfTurn/Radius will
automatically be used for speed below the set value.
Note !
Other special work functions (thruster control, disabling of
special alarms etc.) do not apply without the Work mode being
manually selected.
For a planing boat it is recommended to set the Transition
Speed to the value that represents the speed where the hull
begins to plane. For a water jet boat it should be set to a value
that represents the speed where it begins giving good response
from the main steering.

The Nav Gain determines how many degrees the autopilot must
change the vessel’s heading in order to bring the vessel back on
track, using the Cross Track Error and the vessel’s speed (refer
also to the Operator Manual/User Set-Up Menu/Nav Mode).
Range:
0.5 to 7.
Default:
Depends on the boat length.
Minimum rudder
Some vessels may have a tendency of not responding to small
rudder deflection around “used” midship position because of a
possible rudder deadband or whirls/disturbance of the waterstream passing the rudder.
By setting the Minimum Rudder to a certain value, the autopilot
will add this value to any given rudder command.
The amount of rudder command is determined by adding the
minimum rudder value and the rudder deadband value to the pfactor value.

Sets a firm or soft approach to the rhumb line when entering the

Default: Firm
Turn Gain
Turn gain determines the initial rudder command when turning
in AUTO and NAV modes.
Increase this value if the amount of rudder is too small when
starting a turn.

Default value is set according to Boat length and Set rate of
turn in the Installation Seatrial Menu.

W Turn gain determines the initial rudder command when
turning in WORK modes.
Increase this value if the amount of rudder is too small when
starting a turn.
Range: 1-320
Default value is set according to Boat length and Set Rate of
Turn in the Installation Seatrial Menu.
Rate Sensitivity
This parameter determines how sensitive the Rate of turn
calculation is for changes in the heading signal. The default
setting will fit most vessels. For vessels that can turn quickly
and have a stable heading compass (high performance compass),
the setting should be reduced if the vessel tends to overshoot,
even with a high setting of counter rudder. For a slowly turning
vessel with noisy compass and unstable Rate of turn, the value
could be increased.
Range:
5 - 25.
Default: 15.

Thruster inhibit
Thruster inhibit is a feature that will block the thruster from
running above a set inhibit speed of the boat. It is a safety feature
to prevent, especially electrical on/off thrusters, from
overheating if out of water on for instance a planning boat or in
rough weather. “No thruster response” alarm will be given
when passing the set limit.
Thruster inhibit will not apply when Man speed source is
selected, only Log or SOG.
Range: 1 – 99 knots.
Default: 10 knots.
Thruster sensitivity
The Thruster sens 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.
If the thruster commands are hunting from side to side, the set
value for Thruster sens may be too low.
If a low value for Thruster sens is needed, consider reducing
Thruster gain (ref. page 86) to avoid hunting.
Range:
Continuous thrusters 0° to 30° in 1° increments
On/off thrusters 3° to 30° in 1° increments.
Default: 1° for continuous thrusters, 5° for on/off thrusters.
Thruster gain
(Only applicable for Continuous and Danfoss thrusters)
Since a continuous type thruster can be operated both in
“Continuous” and “Adaptive on/off” mode (ref. Thruster
Drive setting, page 88) the Thruster gain parameter is dual.
The parameter associated to the thruster drive mode setting will
be the one displayed and adjusted.
86
20222469 / B
Advanced Settings
When operating in “Continuous” mode, the thruster gain
setting determines the power from the thruster versus heading
error. For higher values, the power increases with the same error
signal. If the vessel tends to oscillate around set heading, the
value should be decreased. If the vessel has a slow approach to
set heading, the value should be increased.
When operating in “Adaptive on/off” mode, the setting
determines the fixed power from the thruster. Higher value gives
more power. Some thrusters may be so powerful that even the
shortest command makes the vessel to overshoot, especially at
low setting of Thruster sens. If so the Thruster gain must be
reduced. If the power is too low for the vessel to regain heading
within reasonable time, the setting should be increased.
Range:
0.05 to 2.00
Default: 1 for Continuous thrusters
2 for Adaptive on/off operation
(Ref. Thruster Drive Setting, page 88)
Minimum thrust
(Only applicable for Continuous and Danfoss thrusters)
The Minimum thrust determines the amount of power (in % of
maximum control signal) that is applied as "first command
signal". (Refer to page 66)
Range:
0 to 50% in 1% increments.
Default: 0%.
Thruster hyst
(Only applicable for Continuous and Danfoss thrusters)
When applying a command signal to a proportional valve, a
certain amount of deadband may occur, dependant on the
directional change of the command. Therefore, a certain “extra”
menu-adjustable command signal is generated and either added
or subtracted to the command signal in order to compensate for
the deadband. Hence the command signal gives the required
power without the “loss of deadband signal”.
Range:
0 to 10% in 1% increments.
Default: 0%.
20222469 / B
87
Simrad AP50 Autopilot
Thruster Drive
(Only applicable for Continuous and Danfoss thrusters)
For On/Off thrusters, it is important to keep thruster activity to a
minimum. TI51 therefore has a feature that adaptively adjusts
the length of each thruster command to bring the vessel back on
heading without over- or undershoot.
When setting Thruster drive to “Adaptive on/off”, this feature
will also apply for continuously type thrusters in all Work
modes (not Follow Up). For operations where the Thruster sens
can be of some degrees, on/off adaptively will reduce activity
also for continuous type thrusters.
Refer also to the Thruster gain setting for optional
performance.
Default: Continuous
Response delay
(Only applicable for Continuous and Danfoss thrusters)
This parameter determines the slope-time of the start/stop signal
to the thruster. Increased value will give softer start/stop and less
wear of the thruster. Big powerful thrusters normally need a
longer start time than small rapid thrusters.
Range:
0-2 seconds

6.17 Environmental Protection
Each part of a Simrad autopilot system has a two-digit IP
protection code.
The IP rating is a method to classify the degree of protection
against solid objects, water ingress, and impact afforded by
electrical equipment and enclosures. The system is recognized in
most European countries and is set out in a number of British
and European standards.
The first code number describes the protection against solid
objects and the second number describes the protection against
liquids.
FIRST NUMBER

Approvals
8 APPROVALS
8.1 Product compliance schemes
Electronic navigation equipment on boats and ships within the
European Common marked (EC) are regulated by two main
directives:
• Directive 89/336/EEC Electromagnetic Compatibility, "EMC
directive"
- This directive is applicable to more or less all boats,
including leisure boats. Refer CE mark section below
• Council Directive 96/98/EC of 20 December 1996 on marine
equipment, "Marine directive" or "MED"
- This directive is valid for ships that come under
international conventions such as LL66, Colreg, Marpol,
and Solas. Refer to the Wheelmark section below
The Marine directive requirements include the requirements of
the EMC directive, and a product which comply with the
Marine directive is therefore automatically also in compliance
with EMC directive.
CE mark
The CE mark is placed on a product as the manufacturer’s visual
identifier that the product meets the requirements of relevant
European Directives. The CE mark is mandatory for a wide
range of products sold within or exported to the European
market, and applies to all Electric- and Electronic equipment.
When the equipment is tested according to the requirements in
the Directive 89/336/EEC, the CE marking is applied to the
units to symbolize Simrad’s Declaration of Conformity with the
directive.
The CE declaration for any CE marked unit can be obtained
from your Simrad distributor.
Wheelmark
The Wheelmark symbol (Mark of Conformity) is an
accreditation that is required for equipment placed on board
ships for which safety certificates are issued by, or on behalf of,
Member States of the European Union.

Simrad AP50 Autopilot
Before a wheelmark can be affixed to a product, an independent
organization appointed by a European national authority (a
Notified body) has to undertake conformity assessment, and test
reports and a MED-B certificate have to be issued. These test
reports and certificates have to be kept by the manufacturer.
The manufacturer is allowed to affix the Wheelmark symbol and
issue a declaration of conformity only if the manufacturer also
holds a relevant QA certificate (MED-D).
The wheelmark shall be followed by:
- the identification number of the notified body (Det Norske
Veritas = 0575) which has performed the conformity
assessment procedure and the last two digits of the year in
which the mark is affixed.
Note !
When a complete system (e.g. an autopilot system) is wheelmark
approved, only the main unit(s) in the system wears the
wheelmark symbol. This to avoid the misunderstanding that all
standard and optional units in a system retain their wheelmark
approval 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.
EU’s official database (MarED Product Database) contains
information about wheelmarked equipment. This database is
found on:
http://www.mared.org/
8.2 Certificates
The certificates and CE declarations for any wheel marked
equipment can be obtained from your Simrad distributor.
