In order to operate the detector under optimum conditions, the inductance of the coil should be maintained between 100uH-300uH. With the coil inductance constant, the number of turns of the coil has an important relationship with the perimeter. The smaller the perimeter, the more loops there are. Since there may be buried under the road with various metal materials such as cable lines, steel bars, and sewer covers, these will have a great influence on the actual inductance of the coil. Therefore, the data in the above table is for reference only. In practice, the user should use the inductance tester to actually measure the inductance of the inductor to determine the actual number of turns, as long as the final inductance of the coil is within a reasonable operating range (eg, between 100uH and 300uH).
When winding the coil, leave a sufficient length of wire to connect to the loop inductor and ensure there is no connector in the middle. After winding the coiled cable, the outgoing cable must be made in a tightly twisted form, requiring a twist of at least 1 m 20 times. Otherwise, untwisted output leads will pull in, making the coil inductance unstable. The output lead length should generally not exceed 5 meters. Since the sensitivity of the detection coil decreases as the length of the lead increases, the length of the lead cable must be as short as possible.
The coil is first embedded in a slot cutter on the road. Perform 45-degree chamfering on the four corners to prevent sharp corners from damaging the coil cable. Groove width is generally 4 to 8 mm and depth 30 to 50 mm. At the same time, a slit for the coil lead to the curb must be cut. However, it should be noted that the grooves must be clean and free of water or other liquids. The coil must be straightened when it is wound, but do not stretch too tightly and close to the bottom of the groove. After winding the coil, the twisted output lead is led out through the lead slot. During winding of the coil, an inductance tester should be used to actually measure the inductance of the inductor and ensure that the inductance of the coil is between 100uH and 300uH. Otherwise, adjust the number of turns of the coil.
Installation fixes the position to make it easy to conspicuously, the brake lever faces outward (crossing), the barrier surface and the road surface need to be in the same plane, and when the road surface takes time, the mixed mud surface acts as the foundation of the barrier.
Install the chassis and take out the accessories inside the box.
Place the box in a determined position, open the door, mark with a marker or screwdriver on the hole in the floor of the box, and remove the box.
Use a percussion drill to drill the expansion screw at a few points respectively. The hole depth is 70-80mm. Insert the expansion screw and adjust the level and verticality of the box and tighten the nut.
Install the brake lever to open the door and rotate the crank handle of the motor so that the brake lever in the box is clamped to a horizontal position.
Place the brake lever with the screw hole end horizontally into the clamp groove of the gate in the box, put on the outer brake lever clamp, flat washer, and tighten the nut.
Adjust the gate guard so that the brake lever is in the horizontal position. And make the gate guard just contact with the bar.
The method for installing the gate bar bracket is the same as that for installing the cabinet.
The tension spring adjusts the access gate power and presses the "" and "" keys of the controller to run the brake rod 90 degrees up and down for 4 to 5 times. If the lever is shaken, it means that the balance spring tension is not enough and the brake lever will run to Vertical state.
Disconnect the power, open the box, loosen the cover screws, and remove the cover.
Use a hex wrench to adjust each tension spring screw. (See Figure 3) to make the brake lever achieve the best effect when the drop lever is running.
If the lever raises the lever, it indicates that the balance spring has too much tension. Repeat the above operation (relax the spring screw so that the lever can achieve the best effect when the lever is operated).
If the rod is lifted, the motor is running and the brake lever does not move, which means that the tension of the balance spring is insufficient, adjust the state of the tension spring or increase the tension spring until the brake lever runs normally.
The single spring configuration is as follows:
The length of the brake lever is 6 meters with two tension springs, and the length of the lever is 4-5 meters. Two tension springs are configured. The length of the brake lever is less than 4 meters and a tension spring is configured.
Adjust the number of rotations in each nut the same to avoid unbalanced forces.
Limit adjustment Barrier ex-factory adjustment of the balance of the gate bar to reach the balance of the scope, such as site installation is not perpendicular or horizontal state of the brake bar, the need for fine-tuning, the steps are as follows:
Open the door
Use a Phillips screwdriver to loosen the crosshead screw on the limit stop plate, and slightly turn the limit stop to adjust the brake lever to the horizontal position. Tighten the screw after adjustment.
When the brake rod is not in position, the limit baffle is finely adjusted in the reverse direction, and if it is over the horizontal position, it is the opposite;
When the brake lever does not reach the verticality after the rod is lifted, the fragrance baffle is fine-tuned in the clockwise direction and adjusted to the desired position;
Lock the door.
