6.2 Initial sea trial
EMC conformance
• 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 may result in faulty operation.
Overview
Having checked that the system is functioning correctly, a short sea trial
is now required to complete the setup. It involves the following
procedures:
• Automatic compass deviation correction
• Heading alignment adjustment
• Autopilot operation check
• Rudder gain adjustment
Note: The ST6000 Plus has a built-in calibration capability which
enables it to be fine tuned to suit the individual vessel, its steering
system and dynamic steering characteristics. As supplied from the
factory the unit is calibrated to provide safe stable autopilot control for
the majority of vessels.
The initial sea trial should be performed in the following
circumstances:
• After all the installation, functional test and initial calibration have
been completed successfully
• Before any other changes have been made to the default calibration
settings: check and, if necessary, reset the values to the
recommended levels, as described in Chapter 4
• In conditions of light wind and calm water, so that autopilot
performance can be assessed without the influence of strong winds
or large waves
• In waters clear of any obstructions
Note: At any time during the sea trial you can press standby to return
to hand steering.
