Rudder Limit
There are physical limitations to the angle that the
rudder can move through. If the autopilot attempts to
drive the rudder past these limits, damage to the steering
gear or autopilot drive system may occur.
An internal potentiometer is set to ensure that the Bosun
will not drive the rudder past the set limits.
An external control on the front panel of the Bosun can then be used to
limit the amount of rudder travel to an even narrower range. This can be
used to limit the rate of turn of the vessel. Under normal operation the
external
rudder limit control is set at maximum.
See the Adjustments chapter of the Installation section of this manual.
