6.3 Initial sea trial

Overview

When you have checked that the system is functioning correctly, you
must complete the setup by taking the boat on a short sea trial to:

correct the compass deviation

adjust the heading alignment

check autopilot operation

adjust the rudder gain

Note: The ST4000+ has built-in calibration so you can fine tune it
to suit your boat, its steering system and its dynamic steering
characteristics. So you can perform the initial sea trial, we calibrate
the unit at the factory to provide safe and stable autopilot control for
the majority of boats.

You should perform the initial sea trial:

when you have successfully completed all of the installation,
functional tests and rudder sensor checks

before making any other changes to default calibration settings:
check and, if necessary, reset the values to the recommended
levels described in Chapter 7: Customizing the ST4000+

in conditions of light wind and calm water, so you can assess
autopilot performance without the influence of strong winds or
large waves

in waters that are clear of any obstructions

Note: You can return to hand steering at any time during the sea
trial by disengaging the wheel drive clutch, or removing the tiller
drive pushrod from the tiller pin.

EMC conformance

Always check the installation before going to sea to make sure that it
is not affected by radio transmissions, engine starting etc.
