Chapter 1: Introduction

Chapter 1: Introduction

Congratulations on the purchase of your Autohelm ST30 Compass.
The compass displays heading information directly from the fluxgate

compass or, if the unit is used as a repeater, via the SeaTalk bus using
data taken from another compass instrument or autopilot.

The compass can also be used as a steering indicator to maintain a
given course. Any helmsmans error, to port or starboard, is indicated by
a bargraph at the bottom of the display. This mode is known as “Lock”
mode.

Important Information

All Autohelm equipment and accessories are designed to the highest standard
for use in the leisure marine environment.

Their design and manufacture conforms to the latest Electromagnetic
Compatibility (EMC) standards, but good installation is required to ensure that
performance is not compromised. Although every effort has been taken to
ensure that they will perform under all conditions, it is important to understand
what factors could affect the operation of the product. To avoid the risk of
EMC problems, all Autohelm equipment and cables connected to it should be;

❏ At least 1m (3 feet) from any equipment transmitting or cables carrying

radio signals e.g. VHF radios, cables and antennas. In the case of SSB
radios, the distance should be increased to 2m (7ft).

❏ At least 20m (66 feet) from large vessels equipped with radar.
❏ More than 2m (7 feet) from the direct path of a radar beam.

The following points should also be noted;
❏ Genuine Autohelm cables should be used at all times. Cutting and rejoining

these cables can compromise EMC performance and so should be
avoided unless doing so is detailed in the installation manual.

❏ Autohelm equipment should be serviced only by authorised Autohelm

service engineers. They will ensure that service procedures and replace­ment parts used will not affect EMC performance. There are no user
serviceable parts in any Autohelm product.

❏ Voltage drops below 10v in the power supply to our products can cause

the equipment to reset. This will not damage the equipment but will cause
the loss of some information and can change the operating mode. This
most frequently happens during engine starting, and so to reduce the risk
of this occurring, it is recommended that the equipment is supplied from a
different battery than the one used for engine start.

❏ Some products generate high voltages, and so never handle the cables/

connectors when power is being supplied to the equipment.

❏ Always check the installation before going to sea to make sure that it is not

affected by radio transmissions, engine starting etc.

❏ In some installations, it may not be possible to prevent the equipment from

being affected by external influences. In general this will not damage the
equipment but can lead to it resetting, or momentarily result in faulty
operation.

Please keep these notes for future reference.
