36 SmartPilot X-5 Wheel Installation & Setup Guide
determine the deviation and apply any correction required. The correction procedure
reduces deviation errors to a few degrees.
As magnetic deviation can cause significant compass errors on your boat, you MUST
complete the compass swing before any other seatrial procedure.
To swing the compass:
1. With the pilot in Standby mode, enter Seatrial calibration as follows:
i. Hold down
standby
for two seconds to enter Calibration mode.
ii. When you see the
DISPLAY CAL
screen, press
disp
until you see the
SEATRIAL CAL
screen.
iii. Press
auto
to enter Seatrial calibration.
2. Use
disp
to move through the Seatrial calibration items until you see
SWING COMPASS
.
Note:
If you cannot access Seatrial calibration, you need to disable the calibration lock. This can
be found in Dealer calibration (see
page 52
).
3. When you are ready to start, press
+1,
to select
SWING COMPASS ON
.
4. Press
auto
to start the compass swing.
The Pilot Controller will display
TURN BOAT
.
5. Start slowly turning the boat in circles (keeping the boat’s speed below 2 knots).
You will need to complete at least two circles, taking at least 2 minutes to complete
each 360°:
If you turn the boat too quickly, the display will show a
TOO FAST
message. If this
occurs, apply less helm to turn in a larger circle.
Note:
If necessary, you can quit the correction process by pressing standby or
disp. If you then
want to repeat the deviation correction, return to the
SWING COMPASS
screen.
6. Continue slowly turning the boat until the controller beeps and displays the
DEVIATION
screen. This indicates that the SPX-5 Wheel system has completed
the deviation correction.
Note:
This screen shows the maximum deviation encountered over 360° (not as an east/west
value).
