4.4.1 SMX100 PANEL STATUS INDICATORS
INDICATOR FUNCTION
FAULT INDICATOR
The Fault indicator displays a fault when either a Thermal, Power
Supply or Module Fault occurs on Front panel display. Some units
may have Green Status LED Indicators in addition to the Controller
Display.
A Thermal Fault occurs when the amplifier is operating outside design
temperatures. Should an excessive temperature condition occur, the
+28 VDC Supply is shut down and a Power Supply fault is indicated.
Once the thermal condition returns to the operational limits, the +28
VDC Supply will activate.
A Power Supply Fault is displayed when the +28 VDC Power Supply
voltage shuts down.
Hi VSWR
When the Hi VSWR fault is displayed; the amplifier is subjected to a
condition where the Reflected Power exceeds 40%. The
microprocessor turns down the gain of the preamplifier and displays the
Reverse Power on the LCD Display.
RMT /LCL
When remote displays on the front panel the amplifier is in the remote
control mode of operation via the IEEE-488 GBIP Bus. The address
selection can be done through the front panel using the Control Knob.
Follow instructions on the LCD display.
TOTL/OPRT HOUR
Elapsed time Indication on the LCD display, presents total hours of the
amplifier or operate hours that it has been energized.
