How to Service Zabera Electric Fence Controllers
- 1). Test the fence line voltage at the furthest point from the controller. Determine whether the fence line voltage is correct according to the manufacturer's recommendations for the particular model.
- 2). Verify that the AC power supply to the controller is sufficient if the fence line voltage is inadequate. If not, restore adequate AC power supply to the controller.
- 3). Disconnect the fence and ground wires from the ACC2 controller if AC power supply is sufficient. Check the voltage output at the fence and ground wire terminals with a voltage tester. If voltage output is less than 2,000 volts, contact Zareba customer assistance. Reconnect fence and ground wires if voltage is over 2,000 volts.
- 4). Test the voltage at ground rods along the length of the fence. Voltage at ground rods should be less than 400 volts.
- 5). Add extra ground rods or drive existing rods deeper into the ground if voltage is over 400 volts.
- 6). Disconnect the two-conductor hookup wire that links the ACC2 controller to the fence wire if the ground voltage is correct. Test the voltage at the fence end of the hookup wire. If the voltage at the end of the hookup wire is less than 1,500 volts, the hookup wire is leaking voltage to the ground somewhere. Verify that you're using 20kv insulated hook-up wire.
- 7). Turn off the ACC2 fence connector and reconnect the hook-up wire to the fence if the voltage is over 1,500 volts.
- 8). Inspect the fence line for bad jumpers between lines and bad splices and conductors. Look for shorts in the fence lines or leaks to the ground. Cut back heavy vegetation touching the fence lines and remove any metal objects in contact with the fence lines. Make sure the fence lines are not directly touching any fence poles. Replace any broken or defective insulators.
