Mounting tension spring adjustment turned Barrier power, according to the controller's "▲" "▼" key to brake lever 90 degrees run 4-5 times a barrier, such as a lever off the pole time jitter phenomenon, indicating a balance spring tension not enough, the brake lever moves to vertical. Disconnect the power, Barrier classification, open the box machine, loosen the cover screws, barrier parameter, remove the cover. Use a hex wrench to adjust each screw tension spring. (See Figure 3) so that the brake lever to achieve the best results when run off the pole. If the time bar from the bar jitter phenomenon, indicating a balance spring tension is too great, repeat the operation (the spring screw relax, so that the brake lever to achieve the best results in the fall rod run.) If from the bar, while the motor is running gate lever does not move, indicating lack of balance tension spring tension, or increased state regulation of tension spring tension spring until the brake lever is operating normally. The main structure of inverter motor: NdFeB rare earth permanent magnet synchronous motor inverter from coding. The motor speed can be precisely follow the input frequency changes and changes in the rotational speed when a significant change was constant torque. In power, the situation with the same speed compared to other commonly used motor starting inrush current and volume were minimal, but the torque is 2-3 times that of other motor and when the motor stall for a long time, the electrical current does not work It will rise. Thus lifting the brake lever can be very smooth, road gates, can accurately control the gate (or closing) time consuming, theory accurate to 1/1000 second, and never under any circumstances be damaged motor (not including overvoltage usage).
