2.1.5.2 Power Alarm Trip Settings
These controls are used to set upper and lower alarm points for the forward and upconverter
power meter readings. These limits do NOT cause the program to take any action other than to
log the fault and display it on the Main Screen. If either the forward or upconverter power levels
are outside the limits, the corresponding Power display box on the Main Screen will be
highlighted red. Also, the fault will be recorded in the fault history file, with a date/time stamp,
and the alarm limit vs. the actual level. Again, violating these limits does NOT cause the
program to take any action to reduce or increase power.
• Forward Pwr Low % - Use this control to set the Forward Power LOWER alarm
threshold.
• Forward Pwr High % - Use this control to set the Forward Power UPPER alarm
threshold.
• Upconverter Pwr Low % - Use this control to set the Upconverter Internal Fwd Power
LOWER alarm threshold.
• Upconverter Pwr High % - Use this control to set the Upconverter Internal Fwd Power
UPPER alarm threshold.
• Un-Check to Disable Alarms – Check this box to enable Low/High Power alarm(s)
monitoring and reporting. Uncheck the box to disable Low/High power monitoring and
reporting.
2.1.5.3 Metering/Display Calibration Operation
The Meter/Display Calibration Screen (Figure 9 on the following page) allows the upconverter
LCD “System Forward Power”, “System Reflected Power” and “Upconverter Internal Fwd Pwr”
readings to be calibrated/adjusted. There is also an adjustment on this screen for the Fast
Reflected Shutdown Trip threshold. This is to eliminate nuisance reflected power trips caused
when the ADAPT output is turned on. There is a Meter/Cal Help screen displayed to the right
side of the dialog, which describes most of the controls and their function. More detail on each
control is provided here:
NOTE: that the readings displayed for power are NOT AVERAGED. That is, they are "real-time."
• System Fwd Pwr – Use the Up/Down control to adjust the displayed value for the
upconverter LCD “System Forward Pwr” reading. The reading displayed on-screen
should match the upconverter LCD reading. The displayed value is NOT averaged.
• System Reflected Pwr – Use the Up/Down control to adjust the displayed value for the
upconverter LCD “System Refl Pwr” reading. The reading displayed on-screen should
match the upconverter LCD reading. The displayed value is NOT averaged.
• Upconverter Pwr – Use the Up/Down control to adjust the displayed value for the
upconverter LCD “Upconv Fwd Pwr” reading. The reading displayed on-screen should
match the upconverter LCD reading. The displayed value is NOT averaged.
