4.2 Causes and Remedies for
Common Operational Issues
There are a number of common issues that can affect the
performance of the TracVision G6. The following sections address
these issues and potential solutions.
Blown Fuse, Low Power, or Improper Wiring
Blown Fuse
The antenna unit is equipped with two fuses
mounted on its CPU board. If either of these fuses
has blown or been broken, the antenna unit will
not operate. Refer to "Replacing a Fuse" on page 109
for details on the fuse locations and how to access
the main PCB.
Low Power
If the power cable from the antenna unit to the
power source or ADCU is more than
15 m (50 ft) in length, the power level can decrease
over the course of the cable, resulting in a voltage
level at the antenna unit that is too low to power
the system. Refer to "Connecting the ADCU to
Vessel Power" on page 39 for details on supplying
adequate power to the antenna unit.
Wiring
If the system has been improperly wired, the
antenna unit will not operate correctly. Refer to
"Wiring the ADCU" on page 30 for complete system
wiring information.
Vessel Turning During Startup
If the vessel turns during the 60-second startup and
initialization sequence that occurs immediately after turning
on the power to the TracVision G6 unit, the antenna gyro will
record that variable motion as "standing still." This may cause
the antenna to track improperly. To solve this problem, turn
the TracVision G6 off for at least 10 seconds. Turn the system
back on, making certain that the vessel is either motionless or
traveling in a straight line for the 60 seconds immediately
following power-up.
