Test on common faults of electrostatic induction Cables

Electrostatic inductionPerimeter detectors are very sensitive sensors. To ensure proper use of the system and give full play to its functions, the project installer must carefully read the product instructions before construction, check the cables, ground wires, power cables, and installation according to the product instructions carefully before determining the fault. Then, the test starts after 5 minutes of power-on:

Electrostatic sensor perimeter detector does not work or no switch signal output

1) observe the detector housing check power indicator green light), the green light does not light indicates that the power is not properly connected or not powered;

2) Check the anti-split switch when the power supply lights are on. During the CAP test, the anti-split switch should be pressed down;

3) when the alarm is triggered, the red light is shining, but there is no switch output to disconnect the signal connection line between the detector and the host. Use A multimeter for a disconnection test). Check whether the motherboard plug-in and eight-core plug-in are off.

4) if no test cable is installed, the detector must be connected to at least 3 m test cable, and the test cable is provided with an over-the-air erection to keep at least 20cm of the distance between the sensor cable and the ground or wall;

5) if the yellow light on the detector blinks, a root of the probe cable will be removed. When the yellow light is off, it indicates that the cable is short-circuited with the housing or ground wire, check the feed head and the connector between the feeder and the test cable. Note that the shield layer of the feeder cannot be connected to the test cable. When the probe cable exceeds the detector's nominal value, the yellow light also flashes.

Electrostatic sensor perimeter detector continuous alarm

1) grounding of the probe line.

2) the ground line is not properly connected, and the grounding resistance does not meet the requirements.

3) two or more detectors share a ground wire. The ground wires of each detector are separated and the ground pile distance is more than 2 meters.

4) continuous alarm in direct sunlight or heavy rain conditions, it is recommended to put the detector in the water tank.

5) wire wires around the probe cable must be grounded and separated from the detector's ground. The distance between the wire mesh and the electronic fence should be above 30cm.

Occasional alarm on electrostatic sensor perimeter Detector

1) The sensitivity is too high. You can switch to reduce the sensitivity. 1 to 4), the detector can be

Switch to work mode.

2) branches or movable objects within the probe range should be removed from removable objects within 1 m from the probe cable.

Low sensitivity of electrostatic sensor perimeter Detector

1) the distance between the cable and the wall or the wire fence is too close;

2) The detection cable is too long and ultra-coarse) or the use of ultra-range testing will cause low sensitivity or even unstable operation. Please use the recommended testing line.

The test on the handling of Common Faults of electrostatic induction cables is completed. In the next section, we will introduce you to the debugging of Common Faults of electrostatic induction cables.
