Affinity® LBD-200C-N1 Transmitter
Product Manual
x It is recommended that all grounding bonds be inspected and tested annually to
ensure proper and low impedance connections.
23.4.3 Annual Maintenance
Annual maintenance should consist of verifying that the transmitter is operating in accordance
with licensing authority Rules and Regulations. Use the factory tested transmitter data that was
initially provided with the transmitter, or any performance data taken after the transmitter was
installed. Use this information as a guide for completing the necessary tests, and as a
comparison to data recorded during the tests. Thales offers services to conduct these tests. For
more information, contact Thales Customer Service Department.
23.5 Troubleshooting
The Affinity® transmitter is equipped with comprehensive diagnostic circuitry that monitors the
status of each plug-in module and amplifier segment. The Affinity® front panel contains an LED
display that is used in conjunction with the installed Control and Monitoring system to diagnose
failure modes.
A 14-pin diagnostic interface connector, labeled
J1 located on the back of the transmitter, is
used to assist in troubleshooting. Critical power supply, plug-in module, and motherboard
voltage test-points can be accessed from this location. Should a failure occur, the combination
of diagnostic status LEDs, the Control and Monitoring system, and the diagnostic interface
voltage levels will help identify the failure.
NOTE: Repair of internal modules is not recommended or advised. Contact Thales Customer
Service department should a failure occur to any of the plug-in modules or amplifier segments.
