During the installation of the electronic fence , some failure problems will inevitably occur. If there are relevant technical personnel at the installation site, it is okay. If not, it will be troublesome. One video is playing, and it is not clear where it is. There is a problem, so we also need to reserve some common troubleshooting knowledge, the following content can be directly collected.
I. Judgment and troubleshooting of the host of the electronic fence defense zone
Disconnect the high-voltage insulated wire from the zone host and the front end of the connection, and connect each terminal of the host with ordinary insulated wires to enable the host to operate in a no-load working state. If the fault remains, it may be a host problem; if the host Normal, the fault occurs at the front end, please check the following common faults.
Second, the alarm status display failure of the electronic fence defense zone host
Symptom: The status bar of the host is abnormal.
Judgment: There is cable leakage at the front end fence or internal fracture of the high-voltage insulated wire, resulting in fire or electric leakage at the joint of the alloy wire.
Elimination method of electronic fence
(1) Front end
Use a multimeter to test the resistance value of each joint in sections, whether it is within the normal range. Otherwise, the metal alloy wire should be replaced. At the same time, check the resistance value of the high-voltage line to see if the resistance value caused by breakage or high-voltage ignition is too large.
(2) Find the metal bracket or conductor of the fence that is too close, correct the distance between them, and maintain good insulation.
(3) The power supply voltage of the host is too low (requires that the power supply voltage cannot be lower than 190V).
3. Trouble shooting of continuous alarm display in the zone host
Judgment: There is an open circuit, short circuit and short circuit to ground at the front end.
elimination method
(1) Open end of the front end: use a multimeter to detect the on-off status of the circuit and make a judgment.
(2) Short-circuit condition at the front end: Use a multimeter to check whether there is a string short-circuit in the loop.
(3) The front-end short-circuit to ground: use a multimeter to detect the loop-to-ground resistance (in relatively humid weather), if the resistance to ground is small, there is a short circuit to ground.
4. Trouble shooting when the host in the defense zone does not work or has no display
Judgment: The power supply of the host may be too low or the host may be burnt out.
elimination method:
Determine whether the power supply of the host is normal. If the power supply is normal, the host may be burned out (the power supply voltage is too high or suffers a lightning strike).
5. The host in the defense zone is in the alarm state, but the linkage alarm device has no alarm failure
Judgment: the linkage alarm device is faulty or the host linkage output is abnormal.
Remedy: Use a multimeter to test whether the host's linkage output interface (normally open/normally closed) is normally switched. If the switch is normal, it is the linkage device failure, otherwise, the host linkage output module failure.
These are the common problems of electronic fences. After mastering the solutions to these types of failures, the overall installation and maintenance of electronic fences will basically not have any failures.
