Repairing non-detecting sensor cable damage
If lead-in cable is damaged there are two options for repair, depending on the cable layout. If there
is excess non-detecting cable buried, you can dig it up and reposition it so that it reaches the
processor or decoupler enclosure. The second option is to splice in a replacement section of non-
detecting cable.
The following procedures apply to OC2/SC2 sensor cable. Use these procedures and refer to
figure Figure 125:
to repair lead-in cable damage for SC1 sensor cable. For SC1 and SC2 sensor
cable, you require non-detecting cable of the same length as the damaged cable. You also need
male TNC connectors, female couplers and heatshrink (46 cm for SC1, 30 cm for SC2).
Repositioning non-detecting cable
1. Carefully dig up the full length of the non-detecting section (to the red band).
2. Route the non-detecting section of cable to the enclosure’s location to determine if there is
enough undamaged cable to reach the enclosure.
3. If the length of undamaged cable is adequate, cut the non-detecting cable at the point of the
damage.
4. Using a damp cloth and mild detergent, clean and dry the cut section thoroughly at the point
where the damaged section was cut.
5. Examine the cut end of the cable for any signs of corrosion on the center conductor. If any
corrosion is present, strip back the cable until you reach uncorroded center conductor.
6. Install a male TNC connector on the cut end of the non-detecting cable. See Installing
connectors on OC2 sensor cable on page 121.
7. Test the connector for proper installation. See Cable tests
on page 146.
8. Dig a new trench to the enclosure’s location, bury the cable, and re-connect the cable to the
appropriate connector on the enclosure.
Replacing non-detecting cable
If non-detecting cable is damaged, an equivalent length of non-detecting cable can be spliced in
as a replacement. Follow the directions for repairing longer sections of detecting cable to replace
damaged sections of non-detecting cable. Non-detecting cable must be replaced with non-
detecting cable.
Note The OmniTrax system requires a minimum of 6 m (20 ft.) of lead-in
cable.
Note The 10 ferrite beads must remain in the specified positions on the non-
detecting cable.
Note Do NOT use detecting cable to replace lead-in cable.
