Autohelm ST4000+ Problem

Postby Serenity » Tue Jul 10, 2018 6:16 pm

After some tinkering and a new belt, my Autohelm ST4000+ mark I is almost working. It seems to over steer and not straighten out the wheel soon enough. The result is an S-shaped path through the water.

Has anyone had this problem? Can anyone send me the configuration settings that work for their PDQ32?

Many thanks in advance!

The computer averages the course over a few minutes, even when the wheel is not engaged, if the unit is on. Does this happen when you are going straight for several minutes, or only when engaging after turning onto the course?

Read the manual about the gain control and response profile.
That may be your issue.

Hi Dennis, I had a similar problem with my autopilot before. There are a bunch of parameters that can affect this, including the deviation setting and latitude position, which if I recall ended up being my problem.

Next time I get to the boat (might be a few days) I'll note all the autopilot settings and post them.
