Maxiva Three-Strike Fault Actions
3.3.1
Reflected Power Faults
The TCU monitors reflected power at the Cabinet output and at the System output.
When the reflected power level (typically 10% of the rated power or a 1.9:1 VSWR) is
exceeded the TCU generates an RF MUTE. If after three attempts to restart (three
strikes) subsequent faults occur, the transmitter will turn OFF and operator intervention
will be needed to turn it back ON. The three strike counter resets after 30 seconds with
no faults.

Module Faults
Should a module failure occur (say a power glitch) the TCU will initiate a three-strike
action. This action will cause a reset of only the PA Module experiencing the fault and
not the entire transmitter.
