79 Robust animals: at least 4,000 Volt? Robust animals: at least 4,000 Volt? Switching the device off Switch the device on Problem resolved NO NO NO NO YES YES YES YES The fence supply line & earthing check Check the voltage at the fence using a fence tester! Check the voltage at the fence using a fence tester! Voltage above 6,000 Volt? Checking the fence supply line Check the fence voltage at the end of the fence supply line! Supply line from the device to the fence is faulty Reconnect the fence supply line to the fence! Sensitive animals: at least 2,500 Volt? Sensitive animals: at least 2,500 Volt? Checking the fence system & earthing Check the earthing => Measure the voltage directly at the earthing spike! Voltage directly at the earthing space above 1,000 Volt? Improve earthing Fault in the fence => Voltage loss at the fence Everything OK Tip 3 1. Switch the device off 2. Disconnect the fence supply cable at the fence 3. Switch the device back on 4. Using the fence tester, measure the voltage at the end of the fence supply line cable Tip 4 1. Underground fence supply line The underground cable is faulty => use an underground cable resistant to high voltages 2. Underground fence supply line Check the fence supply line for diversions / interruptions (e.g. is the supply line contacting the building, e.g. ivy, guttering, shrubbery, etc.)? Tip 5 How do I measure voltage directly on the earthing rod? 1. Short-circuit the fence wire approximately 10 m away from the device earthing using iron rods 2. Check the voltage directly at the earthing rod using a digital voltmeter Tip 6 1. Insert earthing rods to a depth of at least 1 m away from the building into damp soil 2. Insert multiple earthing rods at intervals of at least 3 m and connect them 3. Earthing rods must be made of non-rusting material, e.g. stainless steel, or must be galvanised Tip 7 1. Vegetation on the fence => remove it! 2. Conductive material lying on the ground => tie / bind it up 3. Poor conductive material => replace with material that has good conductive properties (< 1 Ohm/m) 4. Conductive material is knotted => use stainless steel ties 5. Insulator breaks through => replace with new insulator 6. Broken metal conductor wires => replace conductive material 7. Improve conductivity => connect conductive material series with each other vertically at intervals of around 200 m
