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

Page 6

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:

The direction indicated on the top of the RFU is correct

No undue mechanical strain is placed on the feedback or linkage

SI-TEX SP-110C 7 of 35

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.

Setting up your GPS Uni t

Because there are a great variet y of GPS units that will work with this autopilot, the followin g is a guide only. For more information, consult your GPS manual.

The GPS unit must be set up to output “NMEA 0183” data at 4800 baud on a pair of wires, which are connected to the SP-110C unit via the rudder feedback connector. The data generated must include at least one of the following:

• The APA sentence.

• The APB sentence.

• The BOD and XTE sentences.

• If only the XTE data sentence is available, the pilot can steer in a restricted manner only. (See later in this section.**)

The GPS unit must be programmed and activated to navigate to a waypoint, or to follow a line joining two or more waypoints (called a route). This unit should then send information to the autopilot from which can be calculated the courseto-steer.

Under the following conditions:

• Several waypoints are linked

together into a single route,

• The GPS unit is set and capable of

“auto-sequence” between them,

• An “arrival zone” of more than

0.05 NM (Nautical Miles) is set so that the GPS can detect when the vessel has reached a waypoint ; then the SP-110C will be able to steer from each waypoint to the next without intervention.

Page 35

** If only the XTE information is available from your GPS unit then your vessel must be on track, and heading in the correct direction, before engaging the GPS unit. The “auto sequence” feature is not available in this instance.

SP-110C Alarms

A number of conditions will cause alarms to sound and an alarm message to flash on the display

Off Course Alarm

In AUTO mode an audible alarm of 3 “beeps” per second will sound when boat heading is greater than 45º from the desired course. A red message will also be displayed on the screen

GPS Alarm

In GPS steering mode an audible alarm of 1 “beep” per second will sound when no GPS data is received by the SP-110C. A red message will also be displayed on the screen.

Compass Alarm

If there is no reading from a compass, or no HDM / HDT data incoming, an audible alarm of 1 “beep” per halfsecond will sound. A red message will also be displayed on the screen.

Low Speed Alarm

When used without a rudder feedback (RFU), if the vessel speed goes below the low speed threshold set in the settings, an audible alarm of 1 “beep” per second will sound. A red message will also be displayed on the screen.

Definition of Terms

SP-110C Display: The

operational control unit with colour display and push buttons.

Heading: This is the magnetic direction of the vessel at the current time.

Course-to-steer: The dir ection (heading) which t he auto pil ot is attempting to maintain.

SI-TEX SP-110C 31 of 35

Note: Prior to engaging GPS mode, a route or destination must be programmed and selected in the GPS for the Autopilot to follow.
