1. System Description

The ST7000 is a modular automatic pilot system

that can be built up to match the individual

requirements of all types of vessels. A range of

high efficiency rotary, linear, and hydraulic rudder

drive units are available to match all types of

steering systems.

The ST7000 is SeaTalk compatible providing full

data sharing with Autohelm range of SeaTalk

instruments.

The control unit has a built in interface which will

accept navigation and wind angle data to

0180/0183 format.

fully comprehensive installation is shown below.

The most basic installation would consist only of a

central course computer, drive unit, fluxgate

compass, rudder reference unit and a single

control unit.

1.1.1 Course Computer

(Cat.No. Z083-12V Cat.No. Z084-24V)

The course computer houses the microprocessor,

electronic control circuitry and power amplifier for

the drive unit. The course computer is splash

proof only and must be mounted in a dry and

protected position. The course computer is

available for operation with 12V and 24V power

supply.

1.1.2 Control Unit (Cat. No. Z082)

The control unit is designed for above or below

deck mounting. The control unit accepts NMEA

0183 navigation and wind angle data input.

1.1.3 Fluxgate Compass (Cat. No. Z130)

The fluxgate compass has been especially

developed for marine application. The compass

contains a gimbal mechanism to permit accurate

readings with pitch and roll movements up to +35

deg. The compass is bulkhead mounted below

decks and connects directly to the course

computer.

The fluxgate compass may be mounted above

deck on steel vessels however autopilot

performance may be degraded due to the

increased motion.

1.1.4 Rudder Reference Transducer

(Cat. No. Z131)

The rudder reference transducer provides the

course computer with a precise rudder position. It

is mounted on a suitable base adjacent to the

rudder stock. The interconnecting cable connects

directly to the course computer connector unit.

1.1.5Auxiliary Alarm(Cat.No. Z035)

The autopilot is provided with an automatic off

course alarm system which sounds from all

control units and provides sufficient audible

warning under most conditions. In cases where a

high power alarm is necessary, an auxiliary alarm

can be fitted. The auxiliary alarm is connected to

the main connector unitvia a two core cable.

1.1.6 Masthead Transducer (Sail Only)

(Cat. No. Z080)

If the installation does not include an Autohelm

ST50 Wind Instrument the masthead transducer

can be connected directly to the course computer

to supply wind angle information.

1.1.7 Type CR Interface Unit

(Cat. No. Z085)

A standard ST7000 course computer can be

connected to the solenoids on a constant running

hydraulic power pack using the Type CR Interface

Unit. The unit also provides connections to

energise a solenoid operated bypass valve if

required.

1.2 Drive Systems

The ST7000 offers a choice of Mechanical or

Hydraulic Drive Units. All vessels with hydraulic

steering will require a hydraulic drive unit (see

section 1.2.3).

Mechanical steering systems may be driven with

either a rotary or linear drive unit. If space permits

the linear drive unit provides the simplest

installation by connecting directly to the rudder

stock tiller arm. It may also be used to power

steer the vessel ifsteering linkage failure occurs.

1.2.1 Rotary Drive Units

The Autohelm Rotary Drive Units provide smooth

powerful steering commands with virtually silent

operation.

A rugged electric motor drives a precision

epicyclic gearbox via a high tensile belt drive. An

electronic clutch is totally fail-safe yet transmits

high torque loads with no slippage.

The drive units can be mounted in any attitude

simplifying installation.
