Raymarine 5000 Autopilot. Help for the hard of understanding.

[oldgit]

Before I start fiddling and make matter worse.
Why does the rudder indicator bar on the display move in the correct direction when I turn the wheel manually but go in the "wrong" direction when using the auto pilot.
It is only the indicator that is doing funny things the rudder is actually turning in the correct direction.

It does have rudder sensor fitted.

That sounds very odd.

On my older Raymarine system the rudder position indicator can be adjusted by physically adjusting the rudder sensor or electronically adjusted using the display calibration procedure. I wonder if there is a setting in the electronic menu which reverses the operation? The manual should help.

Has it ever worked correctly?

Isn't it because the function depends on the mode

In standby it is showing the rudder position but in auto is showing heading error

And in track mode shows XTE and in Vane mode shows wind angle error

ITYWF it is working correctly

Just re read your question
In manual the rudder indicates the position of the rudder where you manually steer to
In Auto the the system moves the rudder to steer to the heading set on the auto pilot.
A simple test:
in manual steer and check that the rudder indicator follows the wheel (this you have done)
in Auto, initially there should be no rudder steer as the required heading is unchanged as you start auto, then press +10 and see if the rudder steers slightly to stbd. Do same for a couple of -10 button presses, system tries to steer to port.
If you have a chart plotter connected in with a route set up (even steer to curser) and set Auto pilot to Track the system will try to steer the boat onto the desires chart plotter heading

H,mm never though of that.

Set up for a motorboat and WAE should not be factor. Perhaps that can be disabled ?



Have downloaded the correct manual for the 5000 Plus auto pilot and have gone through all the different settings.
It all seems OK.
The position sensor has been changed at somepoint.
Would have thought the system would be using the same info from rudder sensor both on standby (turning rudder directly from wheel) and on auto and should give exactly the same rudder position s ?

What is actually happening.
In standby.
Turn helm to starboard and both rudder indicator and auto helm display bar indicates that rudder has moved to starboard.

Engage Auto.
Push +10 and rudder indicator shows rudder going to starboard but autohelm display bar displays rudder ??? going to port. ?

Not stopping the use of the Autopilot just a mystery.

I think you are missing the point
In Auto it does not show the rudder position, it shows the heading error, ie how far off course you are.

If you told it to turn 10 degrees to starboard you are now 10 degrees off course to port .........watch as the boat changes and settles on the new course the indication should reduce, becoming zero again when the new heading is reached.

Thanks - the OP’s confusion notwithstanding, that’s useful to me . With my old SeaTalk1 system, the Compass instrument showed the heading error when in autopilot mode, but since switching to a modern N2k system the SeaTalk1 bridge apparently doesn’t pass the necessary information and the old Compass needle does nothing useful under autopilot. I’ll have a look at the bottom of the pilot controller next time to see if the new ones do the same as the OP’s.

Aha....OK. Understood.
