Warning!
• THE AUTOPILOT IS A
NAVIGATIONAL AID; AN
ADEQUATE WATCH MUST BE
MAINTAINED AT ALL TIMES
WHEN AUTOPILOT IS IN USE.
• THE AUTOPILOT MUST BE
PLACED IN MANUAL MODE
WHEN THE VESSEL IS
STATIONARY AS THE SYSTEM
WILL CONTINUE TO DRIVE THE
RUDDER TO THE END OF ITS
TRAVEL AND DAMAGE TO THE
SYSTEM MAY RESULT.
• IT IS STRONGLY
RECOMMENDED THAT THE
AUTOPILOT NOT BE USED
WHILE NAVIGATING IN
RESTRICTED WATERWAYS
AS WATER CURRENTS,
WIND CHANGES OR RADIO
TRANSMITTER INTERFERENCE
CAN ENDANGER YOUR OWN OR
OTHER VESSELS.
• IF A GPS IS CONNECTED TO
THE SYSTEM, THE AUTO MODE
WILL NOT ENGAGE BELOW A
SPEED OF ONE KNOT AND WILL
DISENGAGE FROM AUTO WHEN
THE VESSEL SLOWS TO ONE
KNOT.

SP-110C Autopilot
System
The SP-110C Autopilot control
system comprises the following units:
• SP-110C display and control head.
• SI-TEX E-compass
• Rudder Feedback Unit
(SP-110CR only).
In addition the SP-110C has to be
connected to a drive unit which
controls the rudder actuator system
in order to complete the full autopilot
system. The actuator system
provides the physical movement to
the rudder responding to the direction
of control signals provided by the SP110C. A rudder actuator system
comprises one of the following:
• Hydraulic system with helm pump
and ram
• Mechanical steering system
The autopilot should be connected
to a:
• Reversing motor / pump set
connected into the existing
hydraulic steering system; or
• Continuously running Hydraulic
Pump with solenoid control.
• Reversing mechanical drive unit
connected to the existing steering
mechanism
Block Diagram of full system
*Dashed line (RFU) only for
applicable for SP-110CR.
The SP-110C display provides full
control of the autopilot system and
indicates different modes for heading,
course to steer and rudder angle.
The system requires a supply voltage
of 12-24 Volts DC (Up to 29V During
Charging)
Installation of System
Components
Ensure you have all the components
of the autopilot.
Tools required:
• Screwdrivers – flat blade and
Phillips head
• Side cutting pliers
• Wire strippers
• Spanners (various) or
adjustable spanner
• 70mm hole saw
• Power drill + assortment of drill bits
• Multi meter (DVM)
• Ancillaries such as tape,
connecting block, screws, cable
ties, etc.
SI-TEX SP-110C 3 of 35
Access for wiring must be provided.
Cables have to be run to the power
switchboard, display, compass,
rudder feedback (if fitted) and
drive unit.
All wiring should be kept as far as
possible from radio aerials and aerial
cables to prevent interference to
the radio and to prevent transmitted
signals from the radio influencing
the SP-110C.
The compass must be mounted a
minimum distance of 1 metre from
any boat compass, radios, speakers
or other products with magnetic
properties to avoid interference. The
SP-110C must have a direct
connection to power supply via a 15
amp circuit breaker or a 15 amp
fused circuit and an isolating switch.
Display Unit
Position:
The SP-110C Head unit should be
mounted in a position accessible to
the steering position and protected
from direct rain or salt water.
• Select a dry position
• For in dash mounting cut a 70mm
(2.5”) hole (an optional mounting
bracket is available and may be
used for display mounting – see
your supplier)
• Drill mounting screw holes
• Mount the display using screws
supplied (304 SS – 6G)
• Fit dome plugs to cover screws
• Ensure motor (yellow) and clutch
(green) wires are not exposed
before connecting power to the
SP-110C
• Connect red wire to + 12 volts DC
(Positive)
• Connect black wire to - 12 volts DC
(Negative)

Compass
Take care when handling the
compass as it is a sensitive piece of
equipment. The compass position
is the most important item in the
installation of the autopilot. Good
course holding is dependent on the
compass being free from magnetic
interference and exces s ive r olling
or pitching.
Position:
• Select a dry position free from
magnetic interference. (Note other
side of bulkheads and deck heads
for magnetic type objects)
• Avoid positions near radios,
speakers, aerial cables or any other
current carrying cable.
• Mount the compass horizontally
with the arrow (bow) pointing in the
same direction as the boat’s bow.
Use non-magnetic screws (316
grade stainless steel)
• Run cable to SP-110C display
position (keep away from other
cables)
• Connect compass cable to
SP-110C compass socket

Rudder Feedback Unit
*Only for SP-110CR version.
The SP-110CR Autopilot is
supplied with an RFU (rudder
feedback unit), which provides to
the pilot a precise position of the
boat rudder.
Position:
• Refer to diagram on page 7
• Mount rudder feedback adjacent to
the tiller (rudder feedback movement
must copy the angular movement
of the tiller). Use mounting bracket
if required
• Note markings on the rudder
feedback unit. P & S indicate the
required movement of the tiller
for course correction (Port and
Starboard).
• Rudder feedback is mounted
with shaft uppermost
• Fit snap lock swivel joint to rudder
feedback arm
• Fit link block to tiller arm
• Fit link arm from rudder feedback
to tiller – adjust for correct angle
• Route cable to SP-110CR
display position
• Connect rudder feedback cable
to SP-110CR rudder socket
• When installation is complete,
slowly move the steering by hand
to ensure:
a)
The direction indicated on the
top of the RFU is correct
b)
No undue mechanical strain
is placed on the feedback or
linkage

Note: The rudder feedback unit is
water resistant. However, if it is to
be mounted in a wet position, some
protection should be provided to
ensure the unit does not become
excessively expose d or submersed
in water.
The rudder feedback unit may be
mounted upside down, in which
case the blue and red wires in the
cable must be reversed (yellow
wire in cable is not used in the
feedback).
Note: The rudder feedback is
factory aligned. The arm should
not be removed or loosened on the
shaft as this will affect the “O” ring
seal.

Initial Operational
Settings (SP-110CR) –
With Rudder Feedback
The initial set up of the SP-110C
is done onc e the system
installation is complete and
power has been connected to
the SP-110C display control. The
set up can be done automatically
or manually Automatic installation
set up
determines the output polarity for motor
direction and rudder limit setting.
The installation procedure is
designed to work on a rudder speed
of approx. 8 to 20 seconds hard over
to hard over. The process may fail
with faster or slower rudder
movement in which case the manual
set up should be used.
The maximum r udder trave l wil l be
set to approx. 33º e ach sid e in the
automatic set up.
Solenoid Connection
• Route suitable two core cable (5
Amp min.) from solenoids to SP110C
• Connect solenoid connection to
either positive or negative supply.
• Fit diodes (eg 1N4007) to
solenoids. Ensure the line on the
diode is on the positive terminal on
solenoid.
SI-TEX SP-110C 9 of 35
Note: If a linear hydraulic drive
is used, the connections are for
mechanical drive.
Note: If the manual set procedure
is used, motor direction and both
rudder end limits must be set.
Notes:
Motor direction can be checked
with SP-110C in MANU AL by
pressing ◄ or ► once power has
been connected to the SP-110C
Compass Alignment
Your electronic com pas s may not be
aligned correctly due to mounting etc.
SP-110C can adjust the heading
reading from the compass to account
for alignment error.
You will require an alternative
heading reference to set the
adjustment (eg. Magnetic compass /
GPS plotter etc)
To commence:
• Switch power on to SP-110C
• Wait until Main Screen is displayed
(Figure 8)
• Hold MODE button, Settings Page
1 will appear (Figure 9)
• Press MODE and AUTO buttons at
the same time. Install Options 1 will
appear (Figure 10)
• Scroll down to COMPASS
ALIGNMENT using the ► Button
• Press AUTO button to edit
• The large Orange number is the
raw heading reading from the
electronic compass
• The large Green number is the
Corrected Compass (Aligned)
heading.
• Press ◄ or ► to change the
Corrected Compass heading so it
matches your alternative reference
(Figure 7)
• Press MODE to exit back to
Settings Page 1
• Press MODE to exit back to Main
Screen
• The live compass reading on the
main screen will be the Corrected
Compass heading.
• All steering will use the Corrected
Compass heading.
