Chapter 2: SPX system settings
2.1 Introduction
This chapter describes the SPX system calibration settings and factory default
settings. The calibration settings can be adjusted to best suit your operating
requirements, but as many will have been adjusted to optimum values when
commissioning the system, they should not normally require further change.
If you change the calibration settings after the SPX system has been commissioned,
you do not need to repeat the commissioning process. However, DO NOT manually
adjust autopilot settings before the commissioning procedures in
Chapter 2
have
been completed
.
Calibration modes
There are four calibration modes, namely Display calibration, User calibration,
Seatrial calibration and Dealer calibration.
Each calibration mode uses a series of screens to set calibration values.
Display calibration
The items in Display calibration affect only the SPX system Pilot Controller. They are
stored in the controller and do not affect any other controllers connected through
SeaTalk.
You can adjust the Display calibration settings as often as necessary – for example, to
add or change information displayed on data pages.
User calibration
The User calibration mode includes settings that you may need to adjust on a regular
basis to respond to changing conditions.
Seatrial calibration
The Seatrial calibration mode is used ONLY when commissioning your SPX system,
as described in
Chapter 3,
so is not described again here. Do not access Seatrial
calibration during normal operation.
Dealer calibration
The Dealer calibration mode includes items that have a significant impact on
operation and can affect your boat’s safety.
After you have completed the initial installation and seatrial, you should not normally
need to alter the Dealer calibration values.
