GHP12InstallationInstructions 15
1. Test the autopilot at a slow speed.
2. If necessary, adjust the gain setting.
3. If necessary, adjust the acceleration limiter setting.
4. Test the autopilot at a higher speed (normal operating conditions).
5. If necessary, adjust the gain and acceleration limiter settings.
1. Drive the boat in one direction with the autopilot engaged (heading
hold).
The boat should not oscillate signicantly; however, a small amount
of oscillation is normal.
2. Turn the boat in one direction using the autopilot and observe the
behavior.
• The boat should turn smoothly, not too quickly or too slowly.
• When you turn the boat using the autopilot, the boat should
approach and settle on the desired heading with minimal
overshoot and oscillation.
3. Select an option:
• If the boat turns too quickly or too sluggishly, adjust the
autopilot acceleration limiter (page 15).
• If the heading hold oscillates signicantly or the boat does not
correct when turning, adjust the autopilot gain (page 15).
• If the boat turns smoothly, the heading hold oscillates only
slightly or not at all, and the boat adjusts the heading correctly,
proceed to step 5.
4. Repeat steps 2 and 3 until the boat turns smoothly the heading hold
oscillates only slightly or not at all, and the boat adjusts the heading
correctly.
5. Repeat steps 1–4 at faster speeds.
NOTE: When you manually adjust the acceleration limiter, make
relatively small adjustments. Test the change before making additional
adjustments.
1. Turn on the GHP 12 using the advanced conguration power-on
procedure (page 16).
2. On the GHC 10, select Menu > Setup > Dealer Autopilot
Conguration > Autopilot Tuning > Acceleration Limiter.
3. Select an option:
• Increase the setting if the autopilot turns too quickly,
• Decrease the setting if the autopilot turns too slowly.
4. Test the autopilot conguration, and repeat steps 2 and 3 until the
GHP 12 performance is satisfactory.
NOTE: When you manually adjust the rudder gain (or counter gain),
make relatively small adjustments, and adjust only one value at a time.
Test the change before making additional adjustments.
1. Turn on the GHP 12 on using the advanced conguration power-on
procedure (page 16).
2. On the GHC 10, select Menu > Setup > Dealer Autopilot
Conguration > Autopilot Tuning > Rudder Gains.
3. Select an option:
• Select Rudder Gain to adjust how tightly the rudder holds the
heading and makes turns. If you set this value too high, the
autopilot may be overactive, attempting to constantly adjust
the heading at the slightest deviation. An overactive autopilot
can cause excess wear and tear on the drive unit, and drains the
battery at a faster-than-normal rate.
• Select Counter Gain to adjust how tightly the rudder corrects
the turn overshoot. If you set this value too high, the autopilot
can overshoot the turn again when attempting to counter the
original turn.
4. Test the autopilot conguration, and repeat steps 2 and 3 until the
GHP 12 performance is satisfactory.
