In Step 3, you identified a suitable GyroTrac
sensor mounting location. Now follow these
steps to mount the GyroTrac using one of the
following options:
Option 1 - Mount to a horizontal surface
Option 2 - Mount to a vertical surface
Option 1 - Mount to a Horizontal Surface
a. Position the sensor on the mounting surface
so that its forward (“FWD”) reference points
toward the bow and is parallel to the vessel’s
centerline within ±5º (see Figure 20).
b. Place the horizontal bracket on the mounting
surface and align it in the same manner as the
sensor.
c. Using the holes in the bracket’s mounting feet
as a template, drill four 1/8" (3.5 mm) holes
in the mounting surface. Later, you will
attach the bracket to the mounting surface at
these four holes.
d. At each of the four mounting feet, insert a #8
fiber washer from above, and insert a #8 fiber
washer from below (see Figure 21). The fiber
washers will isolate the sensor from ground.
e. Secure the horizontal bracket to the mounting
surface using four #8 screws and flat washers.
f. Place the sensor onto the bracket. Make sure
the sensor‘s forward (“FWD”) reference
points toward the bow and its “Up” arrow
points upward.
g. Secure the sensor to the horizontal bracket
using four #10-32 screws, lock washers, and
flat washers. Insert the screws into the four
T-nuts held within the sensor’s housing track.
If you are unable to mount the sensor exactly
level, you can enter offset values into the
system later to compensate for a minor
misalignment. See Appendix E on page 42 for
details.
