3.Tune the feedback gains. Start from [Standby] mode. (The STBY light should be lit on the handheld.)
•Press the [Setup] button and press and light up code 2 (Number 2 LED on the handheld) - this is the rudder gain adjustment code. Run your boat in a straight line at 1/3 to 1/2 full speed and
engage the pilot by pressing the Auto/Stby button. Don’t expect to see good performance yet.
a)If the boat heading and kicker start oscillating, turn the Rudder Gain (code 2) down by pressing and releasing the [Down Arrow] button as many times as required to calm the oscillation.
b)If the boat is making slow “S” turns, turn the Rudder Gain (code 2) up by pressing and releasing the UP Arrow button until the boat heading and kicker start to get “twitchy” then back down on the Rudder Gain a few clicks.
Now enter and light up code 3 on the handheld, this is the Counter Rudder Gain adjustment code.
•If the boat heading has slow oscillations, increase the Counter Rudder Gain. Alternately adjust the Rudder Gain and Counter Rudder Gain until the boat is steering well.
Now initiate some turns with the [Straight Right Arrow] or [Straight Left Arrow buttons.] Hold the button down only long enough to move the kicker 30 degrees or so, then let up. The pilot will try to stop the turn smoothly and then maintain the new heading.
a)If the pilot doesn’t stop the turn very well, decrease Counter Rudder (code 3) gain and increase Rudder Gain
(code 2).
b)If the pilot moves the rudder too far when stopping the turn, increase the Counter Rudder Gain (Code 3)
You should be able to home in on the proper gain settings in a few minutes.
a)If you find that
b)If you find that
You now want to try different speeds and make minor adjustments to the gains. You will probably need to readjust several times at different speeds to get the system working well at all speeds. If you find that it just won’t tune for all speeds consider the following.
You must save and download any adjustments you have made to the Autopilot. To make the
modified setup parameters into start up defaults:
Press and release the [Setup] button (the Setup LED Will light up) then
Press and hold the [Select Load] GPS button (the load LED will light) and then
While holding down the [Select Load] button, Press and release the Deckmount button quickly. Release the [Select Load] Button.
(This will lock in your new settings)
Note: If the autopilot seems to be too active in rough water, adjust the Sea State Filter (code 1). Refer to page 31 for detailed instruction.
