Off Course Alarm
This is the off course alarm angle. It controls the alarm that warns you
if the autopilot is unable to maintain its set course.
The alarm operates if the autopilot strays off course by more than the
alarm angle limit for more than 20 seconds.
The value must be within the range 15 to 40°, and can be adjusted in
1° steps.
Range: 15 to 40°
Default: 20°
AutoTrim
The AutoTrim level setting determines the rate at which the autopilot
applies “standing helm” to correct for trim changes caused by
varying wind loads on the sails or superstructure. The settings are:
Setting Effect Recommended for:
1 Slow trim correction Heavy displacement vessels,
with full keel or transom rudder.
2 Medium trim correction Heavy displacement vessels.
3 Fast trim correction Moderate to light displacement
vessels.
4 Super fast correction Planing power vessels
Default: 3
The default setting (Level 3) should provide optimum performance
with the ST600R autopilot. However, depending on the vessel’s
dynamic stability, an incorrect rate of trim application may result in
poor course keeping due to autopilot instability.
