No rudder response is pretty common. From standby, push the port or stb button. Does the rudder actually turn? Not does the drive run ( although check that 2) but does the rudder shaft move?

 

 

 

 

 

 

 

If not, drive issue , if yes, Rudder angle sensor.

 

 

 

No rudder response means AP is commanding rudder to move, but nothing happening. 

 

 

 

I'm a Simrad tech.

[Simrad autopilot]

Hi, sounds like a weath of knowledge in here. Am having some issues with Simrad gear. I have a NSS evo12 3s, GO12xse, nac 3 auto pilot, RF25n rudder feedback unit, Precession 9 compass, s5100 sounder module, AP44.  It was commisioned by Simrad tech and worked fine for a period. We had to shift the motors back on the vessel by 300 mm there for the RF25N got moved and shifted back. From then on every time the pilot was engaged we got the message "no rudder response " message poping up. Even though this message was popping up it was still showing rudder movement  in the  NSS12 when spinning the wheel with the Autopilot pane opened up in the EVO 12. I tried to do a dock side commission the other day but failed that! Now it wont work at all. This gear is so complex! I followed the simrad comissoning video online but they where using Virtual Rudder Feedback not a RF25N so was extremely hard to follow. Vessel is in Whitianga, id be happy to pay anyone just about what ever they want to fix it! 021 597 216 is my number. Thanks for your help. Love reading the forums. Cheers Geoff
