Note: If a sensitivity profile indicates a drop of 20 dB within a 10 m length of
cable, it indicates that there is likely a problem with either the cable at that
location (e.g., improper conditioning, kinked, damaged cable) or with the fence
condition at that location (e.g., loose, sagging, stretched).
Note: It is recommended to save a UCM file that includes the recorded sensitivity
profile. This can be useful for future maintenance and troubleshooting activities.
The Sensitivity Profile procedure is best conducted with two people, one to cause
the fence disturbance and one to operate and monitor the UCM Profile window.
1. Establish a connection between the UCM and the processor.
2. Select the Side A Cfig tab and then select the Profile button.
3. Verify that the All radio button is selected, and then select the Record button
to begin recording the Sensitivity Profile for Side A.
4. At the start point of detecting cable for Side A, begin dragging the screwdriver
along the fence fabric.
5. Maintain consistent pressure and a steady pace and continue dragging the
screwdriver along the fence fabric near the sensor cable until reaching the
end of the detecting cable.
6. Repeat this process, dragging the screwdriver from the end point back to the
start point.
7. Select the Stop button to stop recording the Sensitivity Profile.
8. Review the Sensitivity Profile to verify that it was successful. Look for a
reasonably flat response that is somewhat lower near the end of the cable
than at the beginning (typically a 20 dB drop over a 300 m cable).
Note: You can use the Disable function on the Profile window to trim out the
areas with low signal responses at the beginning and end of the Sensitivity
Profile by specifying the range of Meters and selecting the Disable button.
9. Once you are satisfied with the profile, select the Update button to load the
Sensitivity Profile data. If the recorded Sensitivity Profile is not acceptable,
select the Undo button and repeat the profile procedure.
10. Close the Profile window and download the Sensitivity Profile data to the
processor.
11. Repeat this procedure for the Side B sensor cable.
Detection parameter setup
The FlexZone detection parameters are setup independently for each cable side.
The Side A Cfig tab settings apply only to the A side sensor cable and the Side B
Cfig tab settings apply only to the B side sensor cable. FlexZone detection
parameters include the cable Threshold, the segment Threshold, the Event
Window, the Event Count and the Alarm Window.
