8 Troubleshooting and Maintenance
8.1 Maintenance & Safety
The BDA has been engineered for easy maintenance and for safe operation. This has been
achieved as follows :
! BDA Controller provides fault monitoring and accurate status report through LED.
! The 28V DC Power-supply is over-rated for actual requirements.
! Boosters are monitored for both Over-current and Under-current (most failures are sensed
this way).
! Cabinet temperature is monitored for excessive temperature.
! Components are easily removable via quick connect DC and RF connectors.
8.2 Maintenance Philosophy
Field maintenance should require a screwdriver, a multi-meter, spares of each of the active
BDA component parts, and a Portable Radio to monitor off the air signals. There is no
requirement to have any test equipment to accomplish most service repairs.
! All BDA component parts have been designed for reliable long life operation.
! The BDA Controller performs ongoing extensive built in diagnostics.
! Corrective action can often be taken without detailed technical knowledge or the need for
any test equipment.
