When the Main Control looses communication with RF Control or when it is not able to detect it after
being turned on.
When there is a uncorrectable error when reading microcontroller flash memory from a critical region.
When the TWTA is in this mode all the components, except the Main Control Board are disabled, to
protect from damage. Front panel display will be switched off and the external communication port
might be disabled (depends on the type of the communication port). To clear a Flashing Reset the
TWTA must be power-cycled. If the condition that caused the FLASHING RESET remains, the
amplifier will enter the FLASHING RESET mode again.
Gassy TWT:
If the TWTA has been inactive for several months the TWT may build up gasses. This allows the TWT
to arc internally and cause repeated TWTA faults.
To correct this condition, operate the TWTA for an extended period with no input pulses. When a fault
occurs, reset the TWTA and return to operate. A TWT that is recovering will be evidenced by a
widening period between faults. The length of time required will be determined by the particular TWT,
possibly up to twenty-four hours.
The TWTA should be operated periodically to prevent gassing.
Internal Pulse Generator:
The Internal Pulse Generator can be controlled remotely (Refer to the “10000 Series Communication
Protocol” document for more details) and from the Front Panel Display (see page 8).
