Some common faults and maintenance methods for parking lot barriers
In daily life, people can often see such devices as Daozha, and the main function of parking barriers is to help people better manage all kinds of vehicles entering and exiting. With the continuous development of the automotive industry and the ever-increasing number of automobiles, the demand for barriers is also increasing, and higher requirements have been placed on the performance of barriers. However, barriers are electronic products after all, and sometimes they are still There will be some faults, the following will take a look at some common failures and maintenance methods parking barriers.
First, the parking lot can not rise and fall Barrier
maintenance methods: 1, first check whether the electricity, without the burnt fuse, if the fuse melting off, have to do a comprehensive inspection.
2. Unplug the underground cable plug in the communication room and measure if the three red, white and yellow wires of the motor are connected. If they are the same, the red, white and yellow wires in the underground cable are disconnected; The three wires are measured at the plug connected to the head. If they are connected, the line from the end of the door to the communication room is broken (including the poor contact of the plugs). If it is still unreasonable, directly measure whether the motor stator coil is open circuited.
3, motor lead only red, yellow, and white, respectively, and white, respectively, to see if the motor stator is hot, if the hot powerful, indicating that the motor thermal shutdown can not be switched off, if not hot, check 20UF start capacitor is invalid.
4, the motor is still good or not switch, and then measure the blue, green, gray three limit signal line is short circuit.
5, motor line, signal line is good, or can not be switched, indicating that the control box is faulty.
Second, the parking barrier switch failure
Maintenance method: First test whether the motor red (yellow) color and white line are connected, and then measure whether the blue and gray (green) color signal lines and the K2 (K1) sensor switch are short-circuited.
Third, the parking switch but can not stop Barrier
repair method: Description motor can switch the line red, white, yellow three lines there is no problem, the signal line is not short-circuited. The main reason is that the limit signal is not sent to the controller or the controller limit function is bad.
Fourth, Parking Barrier does not automatically shut down
maintenance methods: 1, limit sensors K1, K2 while open. 2, the public line blue circuit. 3, check the controller is broken.
Fifth, the process operation is often shaking parking Barrier Repair
: Check brake lever length (by weight) and the tension spring is installed or not, whether proportional
VI Barrier parking brake lever kept in place repair method
: 1, bad thyristor control box: a plug control box, automatically run, be worn SCR described.
2. The switch is not in position: Turn the lever to the off position or open position with the handle by hand, and use a multimeter to measure whether the output voltage of the off-position or on-position has changed. If not, the Hall switch is bad.
3. The switch is not in good contact with the unfabricated box plug: Open the gate gate and use the meter to measure the positive and negative voltage of the photoelectric switch. If not, the connector has a problem and must be checked.
Seven, after the power is still not running parking Barrier repair method
: 1, no output voltage control box: see whether the blown fuse box control; see whether the electronic components on the control panel for obvious damage, If there is, please contact the dealer or our company's after-sales service department for maintenance.
2. The capacitor is bad: After pressing the ON/OFF button, the motor vibrates and does not operate. It may be a bad starting capacitor and should be replaced.
3, the motor burns out: The distinguishing method measures whether the two lead wires of the electrical machinery lead through; The smell of insulating paint is strong.
4, switch long-term conduction: pull off the power switch plug-in, gate can open and close, plug in the plug-in switch will not work, indicating that the switch is broken.
5, belt off: find out the door to see if the belt is worn.
Barriers, also known as stoppers, were originally introduced from abroad and were used as a gateway access control device for restricting the movement of motor vehicles on roads. They are now widely used in highway toll stations and car parks to manage vehicle access for the management of vehicle access. Its appearance on a large scale has brought convenience to people's lives. The application of barriers is not only conducive to people's better management of passing vehicles, but also can save a lot of tedious details and allow people to manage vehicles in and out. When entering, it is more convenient and effective.
Although parking lot barriers give us more convenient and quicker management, we can make the access to vehicles more orderly. However, for the later use of Daozha, it also needs a lot of attention, some common faults are still good for timely maintenance, of course, is also very important for daily maintenance. Parking barriers bring more than just a means of management and measures, but also effectively provide security and social civilization.
