TracVision G4 Technical Manual
If uncertain of the best location
for the sensor module, make a
temporary installation and conduct
a calibration (as described in
Section 2.7, "Calibrating the
Sensor" on page 40 ). Any
necessary adjustments to the
sensor location can be made based
on the calibration scores.

Choosing the Best Location for the GyroTrac Sensor
• Ideally, the sensor module should be mounted as
low as possible in the center of the vessel – but
NOT in the bilge.
• The mounting surface should be free of excessive
vibration and flexing.
•
Maintain at least four feet (1.3 m) separation
between the sensor module and any magnetized
materials, large ferrous masses, cranes, engines,
derricks, other antennas, cables carrying high
amperage direct current, or battery banks.
• Take extra care when mounting the sensor module
on a steel vessel. Enclose the sensor module in a
fiberglass container and use an aluminum, brass,
plastic, or wood (NOT steel or iron) platform to
position the sensor at least four feet (1.2 m) above
and six feet (1.8 m) away from the steel surface.
•
Be alert for devices that change their magnetic
characteristics when in use, such as CRTs
(computer and TV screens), radar magnetrons,
electric winches, loudspeakers, windshield wipers,
and other devices with DC motors. GyroTrac
cannot compensate for changing magnetic fields
created by these devices.
•
If you need to fabricate custom mounting brackets
for the sensor module, they should be made from
non-ferrous materials such as wood, brass,
aluminum, fiberglass, or plastic. Be sure to use
stainless steel bolts or nails.
Choosing the Best Location for the ADCU
• The ADCU should be mounted in a dry location,
allowing enough room at the back for connecting
system cables.
• The ADCU should be placed so that the LCD
display is visible and the buttons are accessible.
• The ADCU is not susceptible to magnetic
interference and does not need to be mounted on a
level surface.
