FAQ

Questions

1. There are various power sources for electrified fence units: 230V mains, 12V battery and 9V battery. How can I know what's best for me?

2. How can I know if my earth is working well?

3. I have my M300/600/1200 running at half power (yellow knob), but if there is a short-circuit, the display indicates that full power is present.

4. There is too little current in the wire.

5. I cannot get a connector to fit my Gallagher unit.

6. Could my Gallagher electric fence unit be supplying less power as the years go by?

7. My DVM shows "LO", but I cannot find any faults in the fencing.

8. My Gallagher unit interferes with radio/TV reception. What can I do about it?

9. What kind of conductor can I use for my fencing: tape, cord, galvanised wire, vidoflex?

3. I have my M300/600/1200 running at half power (yellow knob), but if there is a short-circuit, the display indicates that full power is present.

Answer:
Both displays on these units only work at full power.
They cannot show they are running at half power.


4. There is too little current in the wire.

Answer:
Check the voltage directly at the unit. If it is OK, the earthing may be insufficient. Make sure that the earth matches the guidelines for the unit.
Another cause can be that the connections in the fencing are making poor contact, are rusty or loose, for example. Make sure you have good connectors and use good wire clamps (#010851 or #010868). There may be leakage into the surrounding area. Make sure that the conductors are mounted in good insulators and that nothing is resting against the conductors (undergrowth).


5. I cannot get a connector to fit my Gallagher unit.

Answer:
There is a "reference earth" on the MBX and M300/600/1200 units - a black knob. A wire should be attached here from a small spike stuck in the ground. This wire must not be connected to the earth on the unit! The unit uses the connection for measuring - it is used as a zero point.


6. Could my Gallagher electric fence unit be supplying less power as the years go by?

Answer:
No. But it's often the case that older equipment involves older mesh which gradually loses its insulation. This can occur through worn insulators, rusty iron wire, tangled nylon wire, leaks in the earth cable or a less effective earthing system.
It can also happen over the years that expanded meshing means the electrified wire has too little capacity for current requirements and needs replacing by a heavier duty type with more joules.


7. My DVM shows "LO", but I cannot find any faults in the fencing.

Answer:
The DVM shows "LO" to indicate that the DVM battery is going flat.
This message has nothing to do with the condition of the fencing. Replace the DVM battery (9 Volt battery pack: 9V MN1604 6LR61).


8. My Gallagher unit interferes with radio/TV reception. What can I do about it?

Answer:
Our equipment is shielded to the highest modern standards and should not cause interference. This kind of interference can have two causes:
