1.1 Installing the Speed Sensor
Please refer to the instructions provided in speed sensor package for
complete installation details and recommendations.
These instructions should be read thoroughly before any attempt is
made to install the speed sensor.
General Points to Remember
The speed sensor should be installed so that it is:
•Ahead of the propellers.
• At least 150mm (6in) from the keel and ideally forward of the keel.
D587
• Near the centre line of the vessel.
• Clear of all through hull fittings and projections.
There should also be sufficient space above the sensor to allow the
paddle wheel assembly to be removed.
Alternative active transducers are available from your Autohelm
dealer. The range includes: bronze through hull speed and a transom
mount triducer.

1.2 Installing the Depth Sensor
Procedures for fitting the sensor to the hull of your vessel are
supplied in the sensor package. Please read these instructions
thoroughly before attempting to install the unit.
General Points to remember
A warning label covers the face of the depth sensor. This label
should be removed before use and the face of the sensor “wetted”
with a household detergent.
The sensor should be installed so that it is:
• near the centreline of the vessel (within 10° of the vertical)
10 Max
D630
• ahead of the propellers and forward of the keel
• clear of all other through hull fittings or projections

1.3 Installation of the Data Processing Unit
The cables from the data processor are 2m (6ft) in length. Therefore,
a 3-way SeaTalk connector block must be sited within 4m (12ft) of
the transducer.
Use the 19mm (3/4in) self-tapping screws to mount the processor
vertically or horizontally to a springer or beam.
D2345-1
Note: Position both the data processor and the SeaTalk connector block
clear of any bilge water.
1.4 Connection to SeaTalk
Plug the free end of the data processor cable into any 3-way
connector block.

1.5 Triducer Installation
There are two triducers available, one for transom mounting and a
second, bronze unit, for through hull mounting. Triducers provide
speed, depth and temperature information and comprise of two data
processors and a triducer housing.
Please refer to the instructions provided in the triducer package for
details on how to install the triducer housing.
