5.1.6 Faults
There are two levels of faults in the system. The first and more severe fault
level is a
shutdown fault
. Shutdown faults are VSWR faults (when the
forward power minus the reverse power is greater than the VSWR Alarm
Set point), over-temperature faults, and some voltage or current monitor
faults. The second and more minor fault is a
notification fault
. Notification
faults can include voltage or current faults as configured via the
calibration menu.
When a temperature fault occurs, the unit will go into the protective
mode, completely shutting-down the amplifier.
When a shutdown fault occurs, the unit shutdowns immediately, and the
fault LED illuminates. The nature of the fault is shown on the display. If
applicable, multiple faults will be displayed, in-line. If more faults exist than
can be displayed in 16 characters, the up and down buttons can be used
to horizontally scroll the display. To change the display mode from the
fault screen to other screens to help determine the nature of the fault,
press the MODE button to cycle through screen. When the fault condition
has been removed (i.e. the temperature has returned to a safe operating
range) and the STANDBY button is pressed, the system will restart. If the
fault has not been removed, the system will not respond to the STANDBY
button.
When a notification fault occurs, the unit continues to operate as before
the fault occurred, and the fault LED illuminates. The nature of the fault is
still displayed, as described above for shutdown faults. To acknowledge
the fault, press the STANDBY button once. This places the display into
normal operation. The fault LED will remain illuminated until the fault
condition goes away, but the unit will operate normally. To see what faults
are still occurring, use the MODE button to step through the displays to the
Fault Display. This will display any notification faults the system may have
tripped.
