Basic Fault Finding Procedure

BASIC FAULT FINDING PROCEDURE

1. Disconnect energiser from the fence line and using a voltmeter or fence compass, test the voltage on the terminals.

  • If the voltage is normal, the energiser is functioning properly (proceed to 2).
  • If not, install another energiser and return the faulty one to your dealer for repair.

2. Reconnect the energiser to the fence.

3 Check the earth system for:

  • Rust
  • Loose connections
  • Insufficient earth stakes

4 Check that the lightning diverter is not faulty / blown.

  • If faulty, it should be replaced
  • If functioning correctly, proceed to 5.

5 Proceed to the first cut out switch and open it (switch off)

6. Using the voltmeter or fence compass, check the voltage on the live section of fence (energiser side):

  • If voltage is low the fault is between this switch and the energizer.
  • If voltage is normal, close the switch (switch on) again and proceed to the next switch.

7. Continue with this procedure until the fault is found.

8. Always check the voltage on both sides of gates and the lead-out.

9. While walking the fence keep an eye open for:

  • Broken or tangled wires.
  • Excessive competition from vegetation.
  • Trees or branches across the wire.
  • Loose or corroded connections.
  • Dirty or cracked insulators.
  • Listen for "popping" as you walk along the fence.

10. The closer you get to the fault / short the lower the voltage reading will become. Beyond the fault the voltage may increase again -if not a dead short.
