4.1.1 Blown Fuse or Improper Wiring
If the antenna unit is installed but entirely non-responsive, there
are two key factors to check as part of the troubleshooting
process:
1. 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 Section 5.4.1, “PCB
Removal and Replacement,” for details on the fuse
locations and how to access the CPU Board.
2. Wiring – If the system has been improperly wired,
the antenna unit will not operate correctly. Refer to
Section 2.3, “Connecting System Components,” for
complete system wiring information.
4.1.2 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 C3 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 C3 off for at least 10 seconds. Turn the system back
on, making certain that the vessel is either motionless or
travelling in a straight line for the 60 seconds immediately
following power-up.
4.1.3 Incorrect Satellite Configuration
The satellite configuration on your IRD must match the satellite
setting on the TracVision C3 system.
•Satellite Aon the TracVision C3 must be the same
satellite as IRD Alternative 1 (or A, based on your
IRD) and must be assigned the IRD DiSEqC 1
setting.*
•Satellite B on the TracVision C3 must be the same
satellite as IRD Alternative 2 (or B, based on your
IRD) and must be assigned the IRD DiSEqC 2
setting.*
*DiSEqC settings apply only to European systems.
Refer to your IRD user manual for complete instructions on
configuring your IRD.
