46 SmartPilot X-5R Drive Installation and Setup Guide
Counter rudder
Counter rudder is the amount of rudder the SPX-5R Drive system applies to try to
prevent the boat from oversteering. Higher counter rudder settings result in more
rudder being applied.
Checking
To check the counter rudder setting:
1. Ensure you have set the response to level
5 , as described above.
2. Motor your boat at cruising speed in clear water.
3. Press
auto
to switch the SPX-5R Drive system to Auto mode, then make a 90°
course change:
•
When gain and counter rudder are both set correctly, the boat performs a
smooth continuous turn with minimal overshoot.
• If the counter rudder is too low, the boat will still overshoot.
• If counter rudder is too high, the boat will ‘fight’ the turn and make a series of
short, sharp turns: this results in a very ‘mechanical’ feel as the boat changes
course.
Adjusting
To adjust the counter rudder:
1. Enter Dealer calibration as described on
page 35 .
1. Access the COUNT RUD screen in Dealer calibration.
2. Use the
-1
or
+1
keys to adjust the counter rudder.
3. Press and hold
standby
for 2 seconds to save the changes and leave Dealer cal-
ibration.
4. Press
auto
to check the SmartPilot performance in Auto mode.
AutoTrim
You may also wish to adjust the AutoTrim setting. AutoTrim determines how quickly
the SPX-5R Drive system applies ‘standing helm’ to correct for trim changes, caused,
for example, by changes in the wind load on the superstructure, or an imbalance of
engines.
Increasing the AutoTrim level reduces the time the SPX-5R Drive system takes to get
back onto the correct course, but makes the boat less stable. If the SPX-5R Drive
system:
•
Gives unstable course keeping and the boat ‘snakes’ around the desired course,
decrease the AutoTrim level.
• Hangs off course for excessive periods of time, increase the AutoTrim level.
Adjusting
Before attempting to adjust the AutoTrim setting, ensure you have sufficient
experience using your SPX-5R Drive system.
If you need to adjust AutoTrim, go up one level at a time and use the lowest acceptable
value. The range of settings is from
OFF (no trim correction) to 6 (fastest trim
correction).
