2. Regularly inspect the front end of the electronic fence, and clean the debris in case of debris.
3. Periodically detect the host pulse output voltage and energy (joules), and test whether the host open circuit or short circuit alarm is normal.
4. The front alloy wire of the electronic fence should be kept tight (especially summer and winter).
5. Replace the aged alloy wire and accessories in time.
6, if not often checked inside the waterproof box, internal there will be ants, gecko, Tengmai, etc. in the inside, which will affect the host using the environment.
two. Electronic fence host common troubleshooting <br> <br> host failure determination: the high-voltage insulated wire connected to the distal end of the host and disconnection, respectively, each of the host terminals connected by a common insulated wire, so that the host no load operation If the fault persists, it may be a host problem. If the host is normal and the fault occurs in the front end, go to the front wall to check whether the alloy wire is connected properly, and if there are any branches or other objects short circuit, please follow the common faults as follows: Troubleshoot.
1. Symptom: The host status bar is not normal. Short circuit, disconnection and other abnormal determination: the front end of the fence there is a cable leak or high-voltage insulated wire inside the fracture, resulting in the ignition of the alloy wire at the junction or leakage.
Method of exclusion:
1. Front end:
Use a multimeter to test the resistance at each joint, in segments, within the normal range. Otherwise, replace the metal alloy wire. At the same time, check the resistance value of the high-voltage wire, whether the resistance value caused by the fracture or high-voltage ignition is too large, and if so, replace the high-voltage wire.
2. Find fence metal brackets or conductors that are too close together, correct the distance between them, and maintain good insulation.
3. The host supply voltage is too low (requires the supply voltage can not be lower than AC: 190V).
4. If the above method fails to solve the problem, please contact Huajunxin Technology Company.
2. Symptom: The host continues to alarm.
Judgment: There is open circuit, short circuit and short-circuit to ground at the front end.
Method of exclusion:
1. Front-end open circuit condition: Use a multimeter to check the continuity of the circuit to determine.
2. Front-end short-circuit condition: Use a multimeter to check if there is a short-circuit condition in the loop.
3. The front-end to ground short-circuit situation: use a multimeter to detect the resistance of the loop to earth (during relatively humid weather). If the resistance to ground is small, there is a short circuit to ground.
3. Symptom: The host is not working or there is no display.
Judgment: It may be that the host's power supply is too low or the host's transformer power supply is burned out.
Remedy: Determine whether the power supply of the host is normal. If the power supply is normal and the host does not work, the host may be burned out (the supply voltage is too high or suffers a lightning strike). Please contact Huajunxin Technology Company.
4. Symptom: The host is in an alarm state, but the linkage alarm device has no alarm.
Judgement: The linkage alarm device is faulty or the host linkage output is abnormal.
Remedy: Use a multimeter to test the host linkage output interface (normally open/normally closed). If the switching is normal, the linkage device is faulty. Otherwise, the linkage output module of the host is faulty. Contact Huawei Technologies Co., Ltd.
5. Symptom: After the above 4 points are eliminated, the host is still in alarm.
Judgment: The construction personnel did not perform the operation according to the specifications during the construction, and the attachment was incorrectly installed, causing the host to work abnormally.
Method of exclusion:
1. Strictly follow the specifications issued by the manufacturers.
2. Put an end to non-matching products (such as high-voltage insulated wires with low voltage).
3. If you still can't solve it, please contact Huajunxin Technology Company to resolve it.
