If the maximum rudder angle is less than 90º then the position of
the RRF or the drag-link must be adjusted so that the operating
arm of the RRF swings through a minimum of 90º and the output
voltage difference is greater than 1 volt from port to starboard lock.
Measure the output of the RRF between the green and blue wires.
Note
If there is less than 1V dc difference, the autopilot will not
commission.

The rudder hard-over angle should only be limited by the rudder
stops and not the RRF linkage. Check that when hard-over the
RRF arm and drag-link, do not form a straight line. If this occurs,
the steering system could become damaged or jammed
endangering the boat and crew. Rectify this immediately by
adjusting the position of the RRF.
