                                 Common faults and maintenance methods of boom barrier 

1. The gate cannot be ups and downs

1. Check whether there are electricity and insurance pipes to be burned. If the fuse is dissolved, a comprehensive inspection must be done.

2. Unplug the underground cable plug in the conveying room, and use the multimeter RX1 gear to measure whether the electrical red, white, and yellow lead are connected. Left and right], then use the R × 10K file to measure whether there is a certain resistance to other cables, [mainly to check whether the line and the line will indirect short circuit]. The three motor cables of red, white, and yellow are not connected [endless resistance], and then detect the red, white, and yellow in the tail wiring box of the machine. Cover, then measure these three lines at the plug connected to the head of the door, assuming the same, indicate that the line breaks from the door row to the transmission room [including poor contact with each plug); Whether the stator coil is disconnected.

3. The motor lead is only red and yellow, and it is not connected with white. Check whether the motor stator is hot. Assuming it is hot, it means that the motor thermal protection stop cannot be switched. Assuming it is not hot, check whether the startup capacitor of 20UF is invalid.

4. Whether the motor is good or not, and then measure whether the three limited signal lines of blue, green, and gray are short -circuited, because the door is automatically stopped in place to pass through the sensor K1 and K2 induction. The door is restricting at the door, and the closure of the door is also limited to the unable to switch and switch [Red Gate Electromechanical].

5. The motor cable and signal line are good, and they cannot be switched, indicating that the control box is faulty.

Why not change the control box first?

If there is a short circuit, it may be burned again. Therefore, we need to check each part without any other faulty hazards before it can be replaced.

Second, the gate can be closed [open] cannot be opened [off]

Nenggan [open] cannot be opened [off], indicating that the motor white public line is good, you can first test whether the electrical red [yellow] color is connected with the white wire, and then measure the blue and gray [green] color signal line and K2 [k1] Whether the sensor switch is short circuit.

Third, can switch but cannot be stopped

Can switch the three lines of red, white, and yellow lines of the motor line, and 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.

Fourth, the gate cannot be stopped automatically

1. Limit sensor K1, K2 opens the road at the same time [Limit sensor is closed by magnetic fields, no magnetic field breaks];

2. Public line blue disconnection.

3. Controller bad: Use the above inspection method to measure the same.

Fifth, what is the failure during the operation of the gate?

During operation, tremor is mainly caused by the length of the gates [weight]. It is not proportional to the spring pull power. If the lower pole will not tremble, the rod will tremble, indicating that the pull spring pulls is too strong, and the pine springs can be tilted; the upper rod will not tremble. Spring to handle.

6. The gate gates are in place

The reason is:

1. Sailing in the control box: When the control box is plugged in, it runs automatically, indicating that the thyristor is worn.

2. The Hall switch is not in place: Shake the gate rod to the position or open position by shaking the handle, and use the output voltage of the universal table to measure the output voltage of the position or the opening position.

3. The Hall switch is not in contact with the misalignment box plug -in: open the gate and use the meter to measure the positive and negative voltage of the photoelectric switch. Assuming no, it means that there is a problem with the plug -in, you must check it.
