1, clutch failure compression spring elastic enough to check, adjust or replace; 2, the clutch is in disengaged position, check whether the handle position closed position; 3, friction clutch compression spring for efficiency, or loose, replace or adjust the spring pressure.

1, orbit obstructions, obstacles should be excluded; 2, gear or chain drive failure, need professional repair; 3, the motor screw loose, tighten the screw; 4, wheel bearing is damaged, replace the bearing manufacturer; 5, rain slipping, need to add weight in the nose area.

1, installation, laying the magnet polarity is not uniform, should be corrected, all the magnets of the same pole, that is N pole or S very uniform upward laid; 2, detector mounted against, be rotated 180 ° to install; 3, the nose part of the sprocket type (number of teeth, size, etc.) are inconsistent, leading to the second side of driving wheel speed is inconsistent, should be replaced into a unified model of the sprocket; 4, two-motor function is inconsistent, one of the brake function, while another does not, it should be replaced into a single function with no motor or brake with brake function unified motor; 5, head internal functional circuit failure approach are: the professional maintenance overhaul, or by a professional electrician replace the function of the circuit; Force.

1, no laying "trackless retractable door control system" go line magnets, please according to the instruction to install; 2, the magnet is not installed correctly, according to the instruction properly installed; 3, bad or install anti-detector, and first detector rotated 180 ° to install, if the situation is still the same, then replace the detector.

1, check whether the control system power, if not, please electricity; 2, check the back labels that handle remote control remote control remote control codes and labels on the back of the receiver part of the remote control codes are the same, if not, then find a unified coding or professional technician, please re-encoding; 3, the circuit itself is the problem, such as Weld, weld, etc., to judge by: 4. In pressing the remote control state power and off, stop keys, listening to the functional head with or without sound relay circuit, and observe the function of circuit indicator on; If nothing happens, please replace the door cable ( connection between the circuit junction box and the function of the line) or check whether there may be reversed; If not, ask someone to repair or replace the function of professional circuit.

1, limit the magnet is not properly installed, please refer to the instructions again to install; 2, infrared anti-collision distance too far, in the head will be within the functional circuit infrared anti-collision distance adjustment knob to adjust the short distance; 3, anti-collision device or bad, from the failure of regulation, the replacement function circuit or the expertise to repair.

1, determined as a separate anti-climbing device or with the door control system supporting the use of anti-climb device, if it is a separate anti-climb devices, because they do not use delay function, even if flying insects or leaves drift down encountered anti-climb infrared detection area, the device will alarm; 2, anti-climb probe damage, leading to emission of infrared emission departments can not receive or not receive some of the infrared receiver, the expertise to repair or re-replacement of the probe; 3, installation of retractable doors over uneven pavement sections, resulting in the emission of infra-red receiver can be sometimes, and sometimes can not receive, please refer to repair pavement professionals, or take other measures.

1, not power, please correct power; 2, access to display power supply is burned out, replace the power supply; 3, access screen-side power supply reversed polarity, replace the polarity; 4, access screen voltage is too low, please display the appropriate supply voltage to increase.

1, power supply instability, turn off the power again after a few seconds off; 2, the display chip is damaged, replace or re-replacement of professional display;
