Hi guys,

A54 2011 has 2 independent Navpilots 711.

One of them in the stationary position shows rudder rotation +/- 7-15 degrees when rudder is stable in 0 position.

The sensor was changed - no effect, same problem persists.

Any ideas?

Thx,

Greg

And if it is not clear, BOTH autopilots need to be calibrated independently.  

It is likely a good idea to run through the whole commisioning process with both, since you might not be sure of either's status.

Hi Bill,
Sorry to say, but it's not the case.

Again, in stationary position, when rudder is in "0" position the screen shows spontaneous changes of the rudder position.
It can change without any boat or rudder movement in the range of 15 degrees in 5-10 min.
On the video you can see just a part of the picture. The boat unmovable as well as rudder.

Shot in the dark Greg ... could there be a ferrous object lingering near the heading compass?

compass is not involved. the boat stays in the marina without any route or direction. Navpilot is in the STANDBY mode.
 

A cell phone sitting nearby can drag a compass well off line

navnet is shut down. the NAVpilot is standby and autonomous. and, again, it's not heading, it's the physical rudder position reading. the rudder stays at 0
