Confirmed (for X5 without rudder
sensors) if a cumulative loss of counts displayed on the panel as "rudder position" exceeds the maximum, then the unit stops steering
What I was noticing is that the degree to which the unit losses counts is very dependent on conditions / sail trim etc.
I went for hours without exceeding the rudder
position buffer yesterday going to weather
, but needed to reset (cycle from automatic to manual) every couple of minutes when heading downwind in heavier conditions. Not sure why the unit would loose counts in one set of conditions and perform well in other conditions.
