POLLING FAULT:
{PASS, FAIL/UNMASKED, MASKED}
backup converter only. Indicates that an interconverter
communication failure has occurred.
RELAY FAULT:
{PASS, FAIL/UNMASKED, MASKED}
backup converter only. Indicates that the RF Relay used
to switch in the backup is not in its expected state.
MINOR:
LEARNED FAULT:
{PASS, FAIL/UNMASKED, MASKED}
backup converter only. Indicates that the Backup could
not learn the settings of one or more Prime Converters.
The SW Fault will flash at one-second intervals to flag
this fault to the user.
BKP TEST FAULT:
{PASS, FAIL/UNMASKED, MASKED}
backup converter only. Indicates that the Backup has
determined, by use of the Backup Test, that it will not be
able to backup one or more Prime Converters. The
Backup Test is done when the
initiated. The SW Fault will flash at one-second intervals
to flag this fault to the user.
CFG CHGD FAULT: {PASS, FAIL/UNMASKED, MASKED}
backup converter only. Indicates that the configuration
of one or more Prime Converters has changed since
being learned by the Backup. Note that the Backup
continuously monitors the settings of all Prime Units in
the system to determine if anything changes. The SW
Fault will flash at one-second intervals to flag this fault to
the user.
RF DTECT FAULT:
{PASS, FAIL/UNMASKED, MASKED}
Indicates a failure when the detected RF input signal
falls below a fixed threshold.
IF DTECT FAULT:
{PASS, FAIL/UNMASKED, MASKED}
Indicates a failure when the detected IF signal falls
below a fixed threshold.
COMMON:
CPLD FAULT:
{PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the Controller PCB Microprocessor
reads back an unexpected value from the CPLD. This is
a check performed on system power up.
FPGA FAULT:
{PASS, FAIL/UNMASKED, MASKED}
Indicates a fault if the Controller PCB microprocessor
reads back an unexpected value from the FPGA. This is
also a check performed on system power up.
