This screen is broken into 3 main areas:
a.
Output Faults - This panel lists the 6 possible output screen faults. A fault would
cause one or more to be highlighted in red while a warning condition would high-
light yellow.
1.
VSWR - VSWR has exceeded fault threshold of 1.9:1
2.
Foldback - VSWR has exceeded foldback threshold of 1.4:1 (VSWR fold-
back is accomplished automatically by reducing the exciter power).
3.
RF Monitor Communications - A warning condition stating that the RF
Monitor board is not communicating over the CAN bus to the Main Con-
troller.
4.
PA Circulator 1 or PA Circulator 2- the power to the circulator reject load
has exceeded 400W. The RF Monitor board is calibrated to give a 3 Vdc
detected sample when the output from the reject attenuator is 40mW (40dB
below 400W).
5.
PA 1&2 Reject - the power to the combiner reject load has exceeded 400W.
The RF Monitor board is calibrated to give a 3 Vdc detected sample when
the output from the reject attenuator is 40mW (40dB below 1kW).
