THE SYSTEM
A basic system consists of the following:
•aDistribution Box (930 618) to collect, process and
output information.
•aCompass Sensor (930 577) to provide heading
information.
• an Autopilot Control (930 700) for the helmsman to
control the autopilot.
•aRudder Feedback Unit (930 807) to provide rudder
position information.
•aConnection Cable (930 276) between the Propilot 700
cable and the Distribution box.
The system also requires a Drive Motor (hydraulic or
mechanical) to activate the vessel’s steering system.
SYSTEM ACCESSORIES
Your system may have some of these accessories as well:
• Power steer remote controls.
• Rudder Position Indicators and Repeaters.
• Compass Repeaters.
•ANavigator.
•Asecond station Propilot 700 Control.
A Brief The Distribution Box is the heart of the system and every
Overview thing connects to this. It contains the computer section that
reads the data from the sensors, i.e. the rudder position
from the Rudder Feedback Unit, the vessel’s heading from
the Compass. It reads the helmsman’s orders from the
Autopilot Control or a Navigator, then calculates, using the
sea state and configuration settings and moves the rudder,
via the Drive Motor to maintain a course.
The Distribution Box contains customised software (618700
V1.0) for connecting a Propilot 700 system.
A link is fitted between Port B and power on the Windvane
Port. The switch on the Light Duty Supply must be located
near the Propilot 700 control.

INSTALLING YOUR PROPILOT 725
Before you Before commencing the installation of your new pilot please
Start carry out the following initial checks:
• that the correct items have been delivered ?
• that the units are undamaged ?
• that the correct voltage drive unit has been supplied ?
• if using a Mechanical Drive Unit, that the correct chain and
sprocket is available ?
• if you are using a hydraulic pump, that you have the correct
size fittings available to connect the pump ?
• that you have the correct type of hydraulic fluid to top up the
steering system once the pump is installed ?
• that you have a power cable of a suitable gauge to supply
power to the system?
• that you have a Circuit Breaker of suitable size for your
system? A Light Duty Switch is required near the Propilot 700.
If you find an error please contact the supplier of the
product immediately.
Before the drilling or cutting of any holes takes place, please
consider the exact location and cable routing that is
required for each unit. Please read this installation section
and any installation information supplied with your units
before you install the system.
Caution! All exposed moving parts must be sufficiently guarded to
prevent accidential damage to persons or clothing.
Suggested We suggest that the following procedure will allow you to
Procedure install the system encountering the least problems.
• Read this section then select the best positions for the units.
• Install the Distribution Box.
• Install the Autopilot Control and route the cable to the
Distribution Box.
• Install the Compass Sensor and route the cable to the
Distribution Box.
• Install the Rudder Feedback Unit and route the cable to the
Distribution Box.
• Install the drive unit. Route the cable to the Distribution Box.
• Route the light and heavy duty power supplies to the
Distribution Box.

• Then proceed to connect all the cables to the Distribution Box
as per the Installation Schematic.
Finally:
• Connect the light duty supply fused at 5 amps, via the Light
Duty Switch.
• Connect the heavy duty supply, see the Drive Unit information
for fuse ratings.
Distribution This is the heart of the system and must be installed in a
Box DRY, accessible position.
Ideally the box should be positioned so that the heavy duty
power supply cables from the batteries to the distribution
box and from the distribution box to the drive unit are kept
to a minimum length. This is particularly important on
sailing vessels where often you are operating on batteries
which are not fully charged.
If the distribution box has to be installed in the engine room
please ensure that the area is properly ventilated to avoid
high ambient temperatures and abnormal condensation
levels.
Compass The Compass Sensor needs to be carefully located. The
Sensor optimum position is to mount it on a convenient (vertical)
bulkhead, as low and as close to the centre line of the boat
as possible. On fast vessels, it is advisable to fit the compass
sensor at least half way back along the centre line.
On steel vessels it is necessary to mount the sensor 2 to 3
metres above the superstructure or to use a Gyro or Pick-off
coil system working from the vessel’s main steering
compass.
The compass sensor must be installed away from sources of
magnetic interference, such as:
Radios, RDF, Depth Recorders, etc: at least 1 metre clearance
Power cables carrying more than 0.5 amp: at least 1 metre clearance
Radar Magnetrons: at least 3 metre clearance
Ship’s engines, large mass steel (soft iron) etc: at least 1 metre clearance
Also, do not install the compass in a position where
magnetic material i.e. tool boxes, drink cans, chain etc. may
be stowed at any time.

Check the proposed location with a hand bearing compass.
This will indicate whether there is a large deviation that
may cause problems. Switch on any electrical equipment
that may cause deviation and check the hand-bearing
compass to see if there has been any change on heading. If
a change is observed the Sensor should not be installed in
this position as the compass heading may not reflect the
true heading of the craft, therefore making autopilot
control inaccurate.
Once the Compass Sensor is installed the transit screw in
the base of the unit should be shortened or removed.
The compass does not have to physically align with the
bow of the vessel because it will be manually aligned later
during the Installation Settings.
The Automatic Deviation Correction routine is explained
later in the Sea Trials section.
Further instructions on the location of the compass sensor
are included with each compass sensor despatched from
Cetrek’s factory.
Autopilot In the interest of safety there must be an autopilot control
Control within reach of the helmsman AT ALL TIMES.
This should be installed in a position convenient for the
helmsman to operate it.
Rudder The Rudder Feedback Unit is connected directly to the
Feedback Unit Rudder Arm, which may be a tiller, quadrant or tie bar, of
the steering system. It may be necessary to construct a
mounting base for this unit.
As the steering gear is often exposed and in an area which
is used for stowage, ensure that the Rudder Feedback Unit
cannot be jammed by ropes, buckets, fenders etc.
You can mount the Rudder Feedback Unit on either side of
the Rudder Stock as changing the “Phasing” so that the
Feedback Unit indicates Port and Starboard correctly is
done manually in the Distribution Box. This procedure is
described later, in the Installation Settings.

The rudder amidships position of the Rudder Feedback Unit
must be accurately centred.
Drive Units Mechanical Drive Units connect into existing mechanical
steering systems.
The size and position of a Rotary Drive Unit should have
been specified when originally ordering the Pilot System.
The unit will have to be positioned to align with the
sprocket which will be fitted to the existing mechanical
steering system. It is essential to ensure that a strong
mechanical mounting is provided for these units as
considerable loads are developed when under use.
