COMMISSIONING SEA TRIAL
The commissioning sea trial should be carried out in open water on a
calm day. The procedures for the remainder of the commissioning
involve continual course and speed changes. It is very important to
maintain a constant lookout at all times. Use proper seamanship when
clearing turns to ensure the commissioning is carried out safely.
The autopilot will be initially operating from the factory default values for
Boat Lag (B LAG) and Rudder Gain (R GAN), these are different for
sail or power boats. During the sea trial the Pilot learning algorithm will
automatically set and adjust the value for Rudder Gain. The values for
boat lag and rudder gain will be checked and adjusted to finely tune the
autopilot steering performance when necessary. The default values are
automatically set depending upon the type of vessel by the setting
BTYPE.
IMPORTANT NOTE
• On the initial sea trial DO NOT EXCEED 15 KNOTS.
• Always maintain a proper lookout.
• If in doubt, disengage the autopilot with the red OFF key on any Pilot
Display or Hand-held Controller, and return to manual steering.
The following parameters should be set and checked during the initial
sea trial.
SET RDM Rudder mid position (reset)
SWING Internal Compass Deviation Correction
BLG 0.3 Boat Lag value
RGN 0.50 Rudder Gain value
SC 6.25 Speed sensor calibration
POWER Power steer mode
