Introduction
Thank you for purchasing a Raymarine prod uct. We are sure your ST60 instrument
will give you many years of trouble-free operation.
This handbook describes how to install and use the Raymarine ST60 Rudder Angle
Indicator instrument. This instrument gives a continuously updated (real time)
display of your vessel’s rudder angle.
The ST60 Rudder Angle Indicator instrument is constructed in a rugged weather
proofed case. It provides a sensitive and stable analog display, to deliver accurate
information under even the most demanding conditions.
Data inputs
The instrument can be used either as a stand-alone unit, or as part of an
integrated SeaTalk instrumentation system.
SeaTalk
When connected to SeaTalk, the ST60 Rudder Angle Indicator can operate as a
repeater to any Raymarine SeaTalk autopilot, or provide rudder position
information to another rudder angle instrument.
SeaTalk enables a number of compatible instruments to be interconnected and
operate as a single, integrated navigational system.
Power and data in a SeaTalk system are fed via a single cable, so that instruments
be connected by plugging them into the network. SeaTalk is flexible enough to
adapt to any number of compatible instruments without requiring a central
D4303-3
Page 8
vi ST60 Rudder Angle Indicator Instrument Owner’s Handbook
processor. SeaTalk can also communicate with non-SeaTalk equipment, using the
internationally-accepted National Marine Electronics Association (NMEA)
protocol.
In a SeaTalk system, each instrument can be either a master or dedicated repeater
unit. A master instrument is directly connected to a transducer (the device that
provides the raw data) and has control of all other equipment on the SeaTalk
network. A slave instrument is not directly connected to a transducer but repeats
information provided by other equipment in the SeaTalk network.
Using with SeaTalk Autopilot
If the ST60 Rudder Angle Indicator is part of a system which includes a SeaTalk
autopilot, the rudder reference transducer is connected to the autopilot and the
Rudder Angle Indicator operates in repeater mode, i.e. as a slave display to the
autopilot, with the autopilot data displayed using the Rudder Angle Indicator
analog pointer.
Stand alone operation
In Stand alone operation, the ST60 Rudder Angle Indicator is connected only to a
rudder reference transducer and does not display information from, or provide
information to, any other instruments.
Options
Linear transducer
A Linear Rudder Reference Transducer option is available for use with ‘bullhorn’
type outboard installations.
Mounting
If you do not want to surface mount your ST60 instrument, options are available
for:
• Flush mounting. If you have ordered the flush mounting option a low-profile
bezel and four fixing screws are also provided.
• Bracket mounting.

Chapter 1: Operation
1.1 Getting started
This handbook describes how to operate, maintain and install the Raymarine
ST60 Rudder Angle Indicator Instrument. The instrument provides a real-time
indication of rudder position as determined by the associated Rudder Reference
Transducer.
CAUTION: Calibration requirement
The ST60 Rudder Angle Indicator instrument is calibrated to
factory (default) settings when first supplied. To ensure optimum
performance on your boat, this product must be calibrated before
use. Do NOT use the product until it has been calibrated using the
procedures in
Displayed information
The ST60 Rudder Angle Indicator pointer shows the rudder position in real-time.
The instrument scale range gives an expanded indication from -40
about zero.
Operation with other instruments
When the ST60 Rudder Angle Indicator is connected to an operational autopilot
via SeaTalk, the instrument acts as slave to the autopilot, which receives data
from the Rudder Angle Indicator Transducer and passes the information via the
SeaTalk bus.

.
° to +40°
1.2 Normal use
As the ST60 Rudder Angle Indicator operates in real time, very little operator
action is necessary during normal use except to observe the instrument as
required to ascertain the rudder angle.
Note:
If rudder angle information is not available on the SeaTalk bus, the analog pointer
oscillates ±10° about the top of the dial.
The key is the only key used during normal operation (see

Chapter 2: Maintenance & Troubleshooting
2.1 Maintenance
Servicing and safety
• Raymarine equipment should be serviced only by authorized Raymarine service technicians. They will ensure that service procedures and replacement
parts used will not affect performance. There are no user serviceable parts in
any Raymarine product.
• Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment.
• When powered up, all electrical equipment produces electromagnetic fields.
These can cause adjacent pieces of electrical equipment to interact with one
another, with a consequent adverse effect on operation. In order to minimize
these effects and enable you to get the best possible performance from your
Raymarine equipment, guidelines are given in the installation instructions, to
enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).
• Always report any EMC-related problem to your nearest Raymarine dealer.
We use such information to improve our quality standards.
• In some installations, it may not be possible to prevent the equipment from
being affected by external influences. In general this will not damage the
equipment but it can lead to spurious resetting action, or momentarily may
result in faulty operation.
Instrument
Certain atmospheric conditions may cause condensation to form on inside of the
instrument window. This will not harm the instrument and can be cleared by
increasing the instrument illumination to the brightest setting.
Periodically clean your ST60 instrument with a soft damp cloth. Do NOT use
chemical and/or abrasive materials to clean the instrument.
Transducer
Refer to the Installation and Maintenance instructions supplied with the
transducer.

EMC installation guidelines
All Raymarine equipment and accessories are designed to the best industry
standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure that
performance is not compromised. Although every effort has been taken to ensure
that they will perform under all conditions, it is important to understand what
factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC performance,
but it is recognized that it may not be possible to meet all of these conditions in all
situations. To ensure the best possible conditions for EMC performance within the
constraints imposed by any location, always ensure the maximum separation
possible between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever possible:
• Raymarine equipment and cables connected to it are:
• At least 3 ft (1 m) from any equipment transmitting or cables carrying
radio signals e.g. VHF radios, cables and antennas. In the case of SSB
radios, the distance should be increased to 7 ft (2 m).
Page 19
Chapter 3: Installation 9
• More than 7 ft (2 m) from the path of a radar beam. A radar beam can nor-
mally be assumed to spread 20 degrees above and below the radiating
element.
• The equipment is supplied from a separate battery from that used for engine
start. Voltage drops below 10 V in the power supply to our products, and
starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may
change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these cables can
compromise EMC performance and must be avoided unless doing so is
detailed in the installation manual.
• If a suppression ferrite is attached to a cable, this ferrite should not be
removed. If the ferrite needs to be removed during installation it must be reassembled in the same position.
Suppression ferrites
The following illustration shows typical cable suppression ferrites used with
Raymarine equipment. Always use the ferrites supplied by Raymarine.
Connections to other equipment
If your Raymarine equipment is to be connected to other equipment using a cable
not supplied by Raymarine, a suppression ferrite MUST always be attached to the
cable near the Raymarine unit.
3.2 Procedures
As it is not possible to describe procedures for all possible installation scenarios,
the procedures given here describe the broad requirements for installing an ST60
Rudder Angle Indicator instrument and its associated transducer. Adapt these
procedures as appropriate, to suit your individual requirement.
D3548-6
Page 20
10 ST60 Rudder Angle Indicator Instrument Owner’s Handbook
CAUTION:
Where it is necessary to cut holes (e.g. for cable routing and
instrument mounting), ensure that these will not cause a hazard
by weakening critical parts of the vessel’s structure.
Unpacking
Unpack your ST60 instrument and check that the items detailed in the
Introduction to this handbook are present.
Each ST60 instrument is supplied with a standard bezel for surface mounting.
Optional mounting kits are available for flush mounting and bracket mounting
the instrument. If you have ordered the flush mounting option, a low-profile bezel
and four fixing screws are also provided.
Fitting the instrument
The ST60 Rudder Angle Indicator instrument can be installed using one of a
number of different mounting options:
• Surface Mounting. Gives a profile of approximately 0.95 in (24 mm).
• Flush Mounting. Gives a profile of approximately 0.25 in (6 mm)

8. Locate the flush mount bracket (6) onto the fixing studs and secure the assembly to the panel with the thumb-nuts (5).
Bracket mounting
A Control Unit Mounting Bracket (Part No. E25009) enables you to mount your
ST60 instrument in locations where other forms of mounting are impractical.
Although bracket mounting provides a useful alternative method for securing
your instrument, it is only suitable for use in positions where the instrument will
not be exposed to water.
To bracket mount your ST60 instrument, do so in accordance with the Control Unit
Mounting Bracket Instruction Sheet.
Fitting transducers
The Rudder Reference Transducer duplicates movement of the tiller arm to
provide the instrument or the autopilot as appropriate, with the exact position of
the vessel’s rudder.
Rotary and Linear Rudder Reference Transducers are available. The Rotary type is
suitable for most installations, but the Linear type is designed for use with
‘bullhorn’ type outboard installations. Refer to the fitting instructions for either
the
Rotary Rudder Reference Transducer

, as appropriate.
or the
Linear Rudder Reference
If you are fitting an ST60 Rudder Angle Indicator instrument as part of a system
which includes a SeaTalk autopilot, the transducer must be connected directly to
the autopilot. The ST60 Rudder Angle Indicator will then act as a slave to the
autopilot.

2. Using Rotary Rudder Reference Transducer template (supplied at the rear of
this handbook), mark the centers for the three securing screws at a suitable
location adjacent to the rudder stock.
3. Drill out the three 3 mm holes then, using the three self-tapping screws provided, secure the Rotary Rudder Transducer in position.
Note:
To ensure precise rudder position indication, the Rotary Rudder Reference Trans-
ducer incorporates a spring to remove any mechanical backlash in the tiller linkage.
Connecting to the tiller
CAUTION:
The Rotary Rudder Reference Transducer arm movement is
limited to ±60°. Care must be taken during installation to make
sure that the arm is opposite the point of cable entry when the
rudder is amidships. Failure to do this could result in damage if the
arm is driven onto its end stops by the steering system.
When connecting the Rotary Rudder Reference Transducer to the tiller, ensure this
is done in accordance with the limits shown in the
Transducer - as fitted
illustration (below), and that the tiller and arm of the Rotary
Rotary Rudder Reference
Rudder Reference Transducer are parallel to each other.
1. With the rudder amidships, ensure that the Rotary Rudder Reference Transducer arm is opposite the point of cable entry and at 90° to the connecting
bar. If any minor adjustment is necessary, loosen the three securing screws,

Note:
Variation within the given limits will not degrade autopilot performance but will
slightly alter the scaling of the ST60 Rudder Angle Indicator display.
3. Cut the threaded rod to length and screw one lock-nut and ball socket onto
each end of the rod.
4. Offer up the rod (with ball sockets) to the Rotary Rudder Reference Arm and
tiller, making adjustments to the ball sockets as required then, supporting the
ball sockets (by means of a suitable wrench) tighten the locking nuts.
5. Press each socket onto its corresponding ball-pin.
6. Move the rudder from side to side and ensure that the linkage is free from any
obstruction at all rudder angles.

2. Release the hydraulic pressure from the vessel’s hydraulic steering system (if
required). Refer to the manufacturer’s instructions for correct procedures.
3. Loosen the starboard bolt that secures the ‘bullhorn’ ram (1) shaft to the end
bracket (2).
4. Assemble the U-bracket (3) over the end bracket (2) and the shaft of the ’bull-
horn’ ram (1).
5. Hand tighten the starboard ‘bullhorn’ bolt to hold the U-bracket (3) in position.
6. Fully open the hose clamps (6) using a flat-blade screwdriver.
7. Hang the hose clamps (6) over the ‘bullhorn’ ram (1).
8. Site the spacers (4) on the ‘bullhorn’ ram (1) and hold, temporarily, with adhesive tape.
9. Pull the shaft (9) out of the linear feedback transducer (5) until the alignment
mark (10) is level with the end of the body (11).
10. Position the linear feedback transducer (5) on top of the spacers (4) so that the
threaded end of the shaft passes through the U-bracket (3).

Note:
The linear feedback transducer shou ld, under normal circumstances, be assembled
with the shaft (9) pointing to starboard. However, if it is not possible to orientate the unit in
this way, port installation is possible provided that the red and green wires are reversed at
the ST60 Rudder Angle Indicator instrument (or course computer).
11. With the adjustment screw and barrel aligned with the spacers, close the hose
clamps (6) around the linear feedback transducer (5) and the ‘bullhorn’ ram
(1).
12. Tighten the ‘bullhorn’ bolt to retain the U-bracket (3).
13. Fit and tighten the nut (7) and washer (8) to the shaft of the linear feedback
transducer (5).
Transducer cabling
General
Each transducer type is supplied with sufficient cable to run from the mounted
position to either the ST60 Rudder Angle Indicator instrument (for operation as a
master) or to an autopilot (for operation as a repeater).
If you are connecting for repeater operation, use the instructions in your autopilot
handbook to connect the transducer to the autopilot.
Running the cable
The manner in which you run the cable will depend on the locations of the
transducer and instrument (or autopilot). The following guidelines are provided:
• When running cable from a Linear Rudder Reference Transducer, leave a loop
of cable at the end of the Linear Rudder Reference Transducer, sufficient to
allow for movement of the ‘bullhorn’.
• If the cable has to be fed through the deck, always use a proprietary deck
gland.
• Where cables are fed through holes, always use grommets to prevent chafing.
• Secure long cable runs so they do not present a hazard.
• Although the transducer cable is fitted with spade connectors for direct con-
nection to the rear of the instrument, it may be necessary to remove these to
facilitate installation e.g. if you want incorporate a junction box in the cable
run or if the cable has to be routed through narrow apertures. Extra spade
connectors are provided, to replace any that are removed when running the
cable. When fitting spade connectors, prepare the cable as at (a) in the following illustration, then fold back the wire strands and insert into the spade connector as at (b). Ensure the wire strands do not extend beyond the rear of the
spade connector insulation, then crimp the connector to the wire.

Connecting the instrument
Introduction
The ST60 Rudder Angle Indicator instrument can be connected:
• To the transducer as a stand-alone instrument.
• To SeaTalk .
Instruments connected to SeaTalk derive their power directly from SeaTalk and no
separate power connection is necessary. Where a SeaTalk system includes an
autopilot, the power for the system is provided by the autopilot.
A range of Raymarine SeaTalk extension cables is available to connect separated
instruments. These cables are supplied with a SeaTalk connector fitted to each
end. A junction box can be used to join cables.
Signal connections
Make the necessary connections to your ST60 instrument (see the
ST60 Rudder Angle Indicator instrument
illustration).

Note:
If the ST60 Rudder Angle
Indicator pointer moves in
the wrong direction with
respect to the rudder
movement, swap the Red
and Green connections.
This may be necessary if
the Rudder Reference
Transducer is fitted in a
non-standard manner.

CAUTION:
When instruments are connected to SeaTalk, ensure that the
power supply for the SeaTalk 12 V line is protected by a 5 A fuse.
Systems with a large number of instruments on the SeaTalk bus may require
connections to the power supply from each end of the system (‘ring-main’ style),
to maintain sufficient voltage throughout the system.

i. Cut the cable to length and trim back an appropriate amount of the outer
sheath.
ii. Cut back and insulate the yellow wire.
4. Connect the screen to the power supply 0 V terminal.
5. Connect the red wire via a 3 A circuit breaker to the power supply +12 V terminal.

Chapter 4: Calibration 23
Chapter 4: Calibration
4.1 Introduction
Before using the Rudder Angle Indicator instrument for navigational purposes, it
must be aligned with the Rudder Reference Transducer to counter any offset and
ensure that the rudder position is accurately monitored.
EMC conformance
• Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting etc.
• In some installations, it may not be possible to prevent the equipment from
being affected by external influences. Although this will not damage the
equipment, it can lead to sp urious resetting action, or momentarily may result
in faulty operation.
4.2 Rudder angle offset adjustment
Rudder angle offset adjustment removes any deviation between the reading on
the ST60 Rudder Angle Indicator display and the Rudder Reference Transducer. To
adjust for any offset, proceed as follows:
1. Center the rudder and check that the display analog pointer is within ±7° of
zero. If the analog pointer reading exceeds the limits ±7°, the Rudder Reference Transducer should be realigned in order to avoid scale inaccuracies, see
Chapter 3, Installation
2. With the rudder centered, press and hold the

Note:
You can enter calibration mode only when the instrument is in master mode. If the
instrument is in repeater mode and you attempt to enter calibration mode, the instrument
will beep twice when the
