Remote
Control
In normal operation, the system is remotely controlled by the track extractor with the RDU
acting as an interface.
An optional Service Displays enables the system maintainer to view, control and display
the system for maintenance purposes.
Local
Control
In Local control, the system can be operated using controls mounted
on the front of the Radar Distribution Unit (RDU); controls include:
- Local or Remote control selection.
- Local transceiver Run and Standby control.
- Viewing of status and BITE data on an integrated LCD display.
- Viewing and adjustment of system configurations.
Safety switches: The following switches are on a safety current loop which, when broken/
open isolate the transceiver and turning unit from the single and three-phase
AC supplies thus stopping antenna rotation and transmission.
- Antenna Rotation: A door mounted removable keyswitch to stop antenna
rotation & transmission.
- Man Aloft Switch: An externally masthead mounted switch to stop antenna
rotation & transmission.
Security switches: Hut door and antenna platform switch.
The state of these switches is reported to the track extract, service display
etc. The switches do not isolate or control any aspect of the system and are
for switch status reporting only.
