Low spot near the end of the cable
1.
Beginning at the end of the sensor cable, remove the cable from the fence to a point several
meters beyond the low spot’s location. Lay the cable carefully on the ground in a straight line.
2.
Remove and discard the connector shell and terminal block from the end of the cable.
3.
Have someone grip the sensor cable’s black jacket near the end, while applying 2.2 kg (5 lb) of
pulling tension to the center conductor with a pair of pliers.
4.
Pick up the sensor cable near the end, and wave and lightly tap the cable at 1 m intervals,
back to a point beyond the low detection spot.
As you tap the cable, listen for the rattle, which indicates that the center conductor is
stabilized.
5.
Cut off any excess center conductor.
OR
,
If the center conductor is retracted, tap back from the end until you locate the center
conductor (by listening for the rattle).
6.
Cut back the cable so that the center conductor and dielectric are the same length.
7.
Reinstall and reterminate the cable, test the sensor zone and recalibrate as required.
Low spot near the middle of a sensor cable
1.
Remove the cable from the fence over the length of the low spot, removing enough cable to
reach a service loop.
2.
Cut the cable at the mid-point of the low spot.
3.
Expose 15 cm (6 in.) of center conductor on each section of cable at the cut.
4.
On one section, have someone grip the sensor cable’s black jacket near the end, while
applying 2.2 kg (5 lb) of pulling tension to the center conductor with a pair of pliers.
5.
Pick up the sensor cable near the gripper, and wave and lightly tap the cable at 1 m intervals,
back to a point beyond the low detection spot.
As you tap the cable, listen for the rattle, which indicates that the center conductor is
stabilized.
6.
Cut off any excess center conductor.
OR
,
If the center conductor is retracted, tap back from the end until you locate the center
conductor (by listening for the rattle).
7.
Repeat steps 4, 5, and 6 on the second section of cable.
8.
Cut back the cable so that the center conductor and dielectric are the same length.
9.
Splice the two sections of cable together using the standard splice kit and re-install the cable.
10. Test the sensor zone and recalibrate as required.
Note
If these methods do not correct the low spot, replace the low sensitivity
cable section with a new length of sensor cable.
