6.1 Antenna rotation warnings
ANTENNA ROTATION SAFETY NOTICE:
When three-phase power is connected to the system and switched ON, the antenna will
rotate immediately regardless of the RUN command status (see conditions below).
When three-phase AC mains supplies are connected and switched ON using the breakers located
within the RDU, the antenna may rotate immediately.
The system will only transmit when a RUN command is received from the track extractor, service
display or is set to RUN using the Local controls located on door of the Radar Distribution Unit.
Antenna rotation can be stopped by any of the following methods:
Antenna Rotation Switch: Place the Antenna Rotation keyswitch located on the front of the
Radar Distribution Unit into the OFF position.
Man Aloft Switch: Place the masthead Man Aloft switch into the OFF position.
RDU Breakers: Isolate the three phase AC supplies using the breaker located within
the Radar Distribution Unit.
Software Emergency Stop: Press the Antenna stop button in the service display RadarView
software (see below).
Caution: The software Antenna Stop function from the Service Display MUST NEVER be
used as the primary means of system isolation for working aloft.
