4.1.1 Blown Fuse or Improper Wiring
If the antenna unit is installed but entirely non-responsive, there
are three 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 Incorrect Satellite Configuration
The satellite configuration on your IRD must match the satellite
setting on the TracVision L3/S3 system.
• Satellite A on the TracVision L3/S3 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 L3/S3 must be the
same satellite as IRD Alternative 2 (or B, based on
your IRD) and must be assigned the IRD DiSEqC 2
setting.*
* The DiSEqC settings only apply to European systems.
Refer to your IRD user manual for complete instructions on
configuring your IRD.
4.1.3 Satellite Signal Blocked
Satellite signals can be blocked or degraded by trees and
branches, buildings, mountains, overpasses, or equipment on the
vehicle itself. Refer to
Section 2.1, “Choosing the Best Location,” to
make certain that the TracVision L3/S3 unit is in the optimal
location. Simply moving the vehicle to clear an external
obstruction will also restore signal quality.
