Item Description Options
Response level This sets the default autopilot system response level setting. The
response level controls the relationship between course keeping
accuracy and the amount of helm / drive activity. You can make
temporary changes to response during normal operation. Evolution
Note: On Evolution autopilots the Response level
setting is available from the main menu: Menu >
Response Level
• Performance
• Cruising
• Leisure
SeaTalk and SPX SmartPilot
• 1 — 9
• 5 (default)
• Level 1 — 3 Minimize the amount of pilot activity. This
conserves power, but may compromise short-term
course-keeping accuracy.
• Level 4 — 6 Should give good course keeping with crisp,
well controlled turns under normal operating conditions.
• Level 7 — 9 Gives the tightest course keeping and
greatest rudder activity (and power consumption). This
can lead to a rough passage in open waters as the SPX
system may ‘fight’ the sea.
* Off course alarm This screen determines the angle used by the OFF COURSE
alarm. The OFF COURSE alarm operates if the pilot strays
off course by more than the specified angle for more than 20
seconds. • 15° to 40°
• 20º (default)
* Turn rate limit This limits your vessel’s rate of turn under autopilot system
control. It is only effective if your speed is greater than 12 knots. • 1° to 30°
• 7º (default)
Power steer This screen determines the behavior of the Rotary or joystick
when in power steer mode.
Note: Power Steer mode is only available if the system
includes a rudder reference transducer and speed data is
available
• Off
• Proportional The steering will behave in proportion to the
movement of the rotary controller or joystick.
• Bang Bang (Joystick only) The rudder will move, and stay
in the direction a joystick is moved.
Hard over time On vessels without a rudder reference transducer, it is of critical
importance to set the hard over time, to ensure accurate autopilot
operation. • Value is seconds
Default value is determined by Drive type selection.
Note: * SPX and SeaTalk SmartPilots only.
