Raymarine forum

Hey Guys, How are you? I hope you well

We have a problem in a system with a ACU 300 and a third part rudder reference, we could not finish the docksize wizard, the system always stopped before the end, I saw that our rudder work has a range of 5K, but Do you know the maximum and minimum that our system recognize? The system recognized the sides, if I steer do STD or Port, P70RS showed without problem, but if I press AUTO a Error Message appear. The system could identify the magnetics but does not matters what I try the rudder limit is always 10 degrees.

Do you have any ideas to test in the system?

Thanks in advance

Hi Felipe,

We would of course advise using the Raymarine Rudder reference unit. This has a max range of 5k ohm and potentiometer has a full deflection from one end of the resistance to the other of 340 degrees, in practice the effective rudder deflection is + or - 70 degrees either side of the central position, ( which will be 2.5K).

Does this help?
