Chapter 4: SPX-5 Wheel system settings
51
WindTrim
WindTrim controls how quickly the SPX-5 Wheel system responds to changes in the
wind direction. Higher wind trim settings will result in a system that is more responsive
to wind changes.
Response level
This sets the default SPX-5 Wheel system response level. 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,
as described in
Smart Pilot X-5 Wheel System Operating Guide.
4.4 Dealer calibration
For information on how to access Dealer calibration, see
Some Dealer calibration values are adjusted during the commissioning process (see
Chapter 2: Commissioning & setup), and once the SPX-5 Wheel system has been
commissioned you should not normally need to change Dealer calibration values.
However if you decide you want to change values in Dealer calibration, be aware that
the Dealer calibration mode includes items that have a significant impact on SPX-5
Wheel system operation and can affect your boat’s safety.

WIND TRIM
Range = 1 to 9
1 to 3 - Least responsive to wind changes (less system activity)
4 to 6 - Moderate response to wind changes
7 to 9 - Most responsive to wind changes (more system activity)

RESPONSE
Range = 1 to 9
Level 1 to 3 minimizes the amount of pilot activity. This conserves
power, but may compromise short-term course-keeping accuracy.
Level 4 to 6 should give good course keeping with crisp, well con-
trolled turns under normal operating conditions
Level 7 to 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-5 Wheel system may ‘fight’ the sea.
WARNING: Dealer calibration
Changing the Dealer calibration values can have a significant
affect on the SPX-5 Wheel system steering characteristics and
therefore on the safety of your boat.
