b
xSUM_VOLTAGE
The Power Supply Voltage fault in older amplifiers. This flag is set if
the module’s input voltage is too high or too low.
b
xSUM_OUTPUT_POWER
This flag signaled the output power fault (Pout fault) in older
amplifiers. In the Outdoor and Antenna-Mount amplifiers, it is set if
the output power is too low or too high, or if it is significantly below
that of the other amplifier in a 1:1 system.
b
xFLT_BUC_FAIL
The BUC (optional) has unlocked, lost power, or has become
disconnected from the module.
b
xSUM_INPUT
This flag is set if a Fault is generated by any Parallel I/O input
programmed to FAULT.L or FAULT.H.
b
xSUM_HARDWARE
This flag is set if any condition indicates a failure of the
microprocessor based circuitry, loss of calibration info, or
programming error.
b
xFLT_TEMP_SHDN
This flag is set if the module’s temperature became so high that it
was necessary to shutdown the amplifier to protect it.
b
xFLT_TEMP_HI
This flag is set if the module’s measured temperature is too high.
b
xSUM_HDW_WARNING
This flag was used to signal a MINOR hardware fault in older SSPA
products. In the SSPAs using this protocol, it is used to signal a
hardware warning.
b
xSUM_PREFL_HIGH
This flag is set if either a Reflected Power High Fault or Warning
exists.
b
xFLT_MAINT_WARN
This flag is set if the Maintenance mode warning is in effect.
b
xFLT_LOCAL_WARN
This flag is set if the Local mode warning is in effect.
b
xSUM_FAN
This flag is set if either fan’s rotational speed is below the fault
threshold, and enough time has elapsed since the last reset that the
fan should have achieved its normal velocity.
b
xSUM_RC_FAILURE
This flag is set if something is wrong with the “Redundancy
Controller” board, which also is used to connect the Reflected Power
Detector and the Fan Monitor. This flag is also used to represent the
“AntDL” (antenna-dummy load switch) fault, in units equipped with
that feature.
3.3.2 “New” Fault Mask
The NEW fault mask is returned if the B
NEW_INFO
byte (equal to 31) is sent in the message going to the
amplifier. This mask also contains flags for both latched and active faults. These flags map more
appropriately to faults detected by this amplifier. See section 3.8.9 for more information on how this amplifier’s
faults are mapped to these flags.
