Adjusting The Autopilot Gain Settings; Reducing The Risk Of Ecu Drive Circuit Overload; Adjusting The Rudder Rate Limiter; Advanced Configuration Procedure - Garmin GHP 10 Marine Autopilot System Installation Instructions Manual

adjusting the autopilot Gain Settings
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. Enable the advanced configuration procedure
2. On the GHC 10, select Menu > Setup > Dealer Autopilot
Configuration > Autopilot Tuning > Rudder Gains.
3. Select an option:
• Select Low Speed or High Speed and use the arrows on the
GHC 10 to adjust how tightly the rudder holds the heading and
makes turns at low speed or high speed.
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 Low Speed Counter or High Speed Counter 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 configuration.
5. Repeat steps 2 and 3 until the GHP 10 performance is satisfactory.
Reducing the Risk of ECu Drive Circuit overload
If you receive an Error: ECU Drive Circuit Overload. See manual
for tips on reducing load error message, use these tips to help reduce
the load:
• Ensure the appropriate pump has been correctly installed on your
boat.
• If possible, use larger inside diameter hydraulic hoses on your
steering system.
• Mount the pump closer to the cylinder to limit the length of the hose
runs.
• Eliminate unneeded hydraulic fittings in the hydraulic fittings.
• If overloading occurs during the autotune procedure, skip the
procedure and manually tune the autopilot.
• Increase the rudder rate limiter setting to slow the fluid rate.
• Reduce rudder gain to limit pump activity.
adjusting the Rudder Rate Limiter
If the ECU Drive Circuit Overload. See manual for tips on reducing
load error message continues to appear, you may need to adjust the
rudder rate limiter.
NOTE: Complete rudder rate adjustments only at the dock or while
your boat is not moving.
NOTE: If you adjust the rudder rate limiter, you must perform the
autotune procedure.
1. Enable the advanced configuration procedure
2. On the GHC 10, select Menu > Setup > Dealer Autopilot
Configuration > Autopilot Tuning > Rudder Rate Limiter.
3. Select Continue.
Autopilot takes control of the rudder.
4. Use the arrows on the GHC 10 to adjust the speed of the limiter.
• 0% is the is the default speed for the rudder rate limiter.
• Lower rudder rate limiter numbers allow the rudder to move
faster between the right rail and left rail.
• Lower rudder rate limiter numbers increase the running current.
• Higher rudder rate limiter numbers decrease the running current.

5. Select Done.
6. Test the rudder rate limiter settings.
7. Repeat steps 2–6 until rudder rate limiter performance is
(page 17).
8. Perform the autotune procedure.
