What is the repair method for electric glass door failure?

1. Check whether the anti-pinch function of the induction electric glass door is causing the induction electric glass door to not open.

Induction electric glass door machine has anti-pinch function, encounter obstacles or induction electric glass door collision will cause the induction electric glass door can not be opened normally, when it reaches three times, the induction electric glass door will stop running, the door will stop opening or closing, encounter this problem only need to push the door leaf to a fully open state can be recovered.

Second, the internal belt of the induction electric glass door is reversed, resulting in the induction electric glass door cannot be closed.

When people pass, the induction electric glass door closes but when it walks away, the induction electric glass door opens and no longer closes after opening. In this case, everyone will think that it can't be closed and opened. This problem is caused by the induction electric glass door being installed or repaired because the technician is unprofessional and the power belt is reversed.

The workaround is:

1. Replace the upper and lower buckle connections of the belt.

3. The controller failure causes the induction electric glass door to be unable to open and close.

When encountering this kind of fault, you need to debug the controller, if the debugging cannot make it return to normal, you need to replace the controller. Therefore, it is recommended that you should find professionals when carrying out maintenance and installation, and you should not lose a big deal because of a small one.

Fourth, when the induction electric glass door is open or closed, there is no response when the power is turned on.

This situation needs to be tested on site, because there are many cases of this problem, such as plugging in the power supply but not powering, it may also be caused by the controller crashing and other reasons. Our technicians can detect this problem on site and solve it in a targeted manner.

Fifth, the remote control problem, resulting in the induction electric glass door can not be opened.

Due to the problem of the remote control of the induction electric glass door, you can unlock it with a look.

6. The induction electric glass door has a door action, but it cannot be closed.

The reason for this is that the sensor has a door opening signal input, that is, there are interferences within the sensing range of the sensor, such as sunlight.

Direct light, moving objects, unstable light sources, etc. You can test whether the induction electric glass door cannot be closed due to the interference signal of the sensor by disconnecting the sensor signal line.

Electric glass door maintenance method: Re-set the sliding method, and install the long belt clamp on the tensioner side.

Compared with the general glass door, the biggest feature of the automatic glass door is the word "automatic", but in contrast, the life of the automatic glass door is lower than that of the general glass door, and it is also more prone to failure. The use of automatic glass doors is still limited to some large shopping malls, hotels and enterprises, etc., and the use of residential buildings is still very rare.

Therefore, if there is a failure and it cannot operate normally, it will cause inconvenience to many people, so it is very necessary to find the problem in time and solve the fault in a timely manner.

Electric Glass Door Functions and Features:

1. In terms of use and control, there are manual and automatic control systems to meet the user's requirements for the opening and closing of industrial doors.

2. On the safe and reliable type, when the door is closed, it is equipped with the function of anti-jamming of the door body, the function of gas safety side, or the infrared sensing function, when encountering resistance or obstacles, the door control system will automatically prevent accidents of people and trucks.

3. In terms of convenience, it is very easy to open and close the sliding door manually, because 90% of the weight of the door has been balanced by springs or weights, and these springs are individually prepared according to the scientific calculation of each door body.

Summary. Fault phenomenon 5: After the electric door switch is in place, the AC contactor COK or CQG is not released (1) The travel switch is damaged, and the control loop cannot be disconnected after the valve is in place, so that the contactor can not be released correctly.

2) There is a short circuit or poor insulation in the local control loop, so that the travel switch does not work. (3) There is remanence in the AC contactor, and the release is delayed. (4) The current of the power circuit is too large, and the contactor contact is burned out.

Hello, glad to answer for you! The fault of the electric door and the treatment method are as follows:

Fault phenomenon 1: the motor rotates, but there is no driving valve (1) the hand automatic switching is damaged, and the manual automatic switching can be replaced (2) the gear of the motor falls off or is worn, and the rotating gear on the vortex rod is not meshed. Press the gears on or replace them.

3) The gap between the rotating claws of the valve is too large or damaged, and the wire mouth of the valve is damaged. (4) The gear between the turbine and the vortex rod is seriously worn or damaged, and the gap is too large.

Therefore, the phenomenon 2: it can be operated on the spot, but the remote control cannot be operated (1) The feedback line is reversed, and the feedback line can be connected. (2) If the remote control transfer switch is damaged, replace it with a new one.

3) There are certain locking conditions, such as liquid level, flow rate, pressure, etc. (4) If the relay is damaged, replace it with a new one.

Fault phenomenon 3: The valve can be opened and closed correctly, but the CRT does not disturb and has feedback (1) The wiring of the terminal strip is loose, and the wiring of the mold can be tightened. (2) If the card is damaged, replace the corresponding card.

(3) If the travel switch does not work or the travel switch is damaged, readjust the travel switch or replace the travel switch.

Fault phenomenon 4: The motor of the motor device cannot be started (1) The power supply is faulty, check whether the empty opening has been closed. (2) If the button fails, check whether the button is damaged.

3) The power supply voltage is too low, find out the reason why the power supply voltage is too low. (4) Torque switch action, check whether the torque switch is acting, and Qingzai readjusts it.

Therefore, guess the phenomenon of opening delay 5: after the electric door switch is in place, the AC early attack contactor COK or CQG is not released (1) The travel switch is damaged, and the control loop cannot be disconnected after the Suili valve is in place, so that the contactor can not be released correctly. 2) There is a short circuit or poor insulation in the local control loop, so that the travel switch does not work.

(3) There is remanence in the AC contactor, and the release is delayed. (4) The current of the power circuit is too large, and the contactor contact is burned out.

Five common faults and solutions for electric doors You refer to yo <>

The reason for the electric door is that the motor does not rotate or the speed of the dismantling is very slow. Solution: Press the reset button several times, or replace the motor with a new one. Others are as follows:

The hand zipper cannot be pulled: straighten the chain, adjust the position between the chain crimping frame and the chain, and re-add the lubricating oil. Loud noise:

Replace the brake disc with a new one, adjust the brake disc, or add lubricating oil. Control failure: Replace the contact or micro switch.

Maintenance of electric doors:

During the use of the electric door, the force should be light and not too large, and the electric door should be opened without obstacles, if there is any, it should be cleaned up after unplugging the power supply.

The surface of the electric door should be cleaned frequently, and a soft cotton cloth should be used to wipe it to avoid scratching the surface of the electric door, and if there are stains, it can be cleaned with water or alcohol. It is important not to clean the electric door to avoid acid-alkali spike loose substances.

Do a good job in the daily maintenance of the electric door at any time, and the flexibility of all kinds of accessories. When it is found that there is damage, repair or replace it in time, and the hardware can be coated with a little fire wax oil or drop some oil to reduce friction and keep the opening and closing of the electric retractable door easy and flexible. The sealing strip and glass strip of the electric retractable door are the two key components of sealing and insulation, and should be replaced in time if there is aging and loosening.

Failure and solution: 1Phenomenon:

The microcomputer does not work, and the electric door does not move, and the electric door does not lose power; Inspection steps: check whether the electric door machinery is sinking, whether the travel switch is bent and Sun Chang, whether the remote and local switch is good, and whether the door head internal break protection switch is normal; Fault cause analysis: the green light is normal, the red light is missing, if the red and green lights are on, it is a fault of the broken protector.

The red light is on, and the three items are not missing, which is a quality problem of the broken item protector; Solution: Short the normally closed contact of the broken item protector and return it to normal. 2.

Phenomenon: Taking the exit door of the fifth phase of the mortar pump as an example, the operation attendant can contact the switch, the switch direction of the door is wrong, go to the spot for observation, and find that the direction of the door is sometimes right, sometimes wrong, mistakenly thinking that there is a problem with the phase sequence of the motor, and after the new phase change sequence, the fault of changing the shirt is still not discharged; Inspection steps: check whether the three direct resistances of the electric door motor are balanced, whether the opening and closing strokes are correct, and whether the electric door machinery is sinking; Check the results:

The direct resistance of the electric door motor is less, the stroke is normal, and the electric door head is not sinking; Fault cause analysis: because the electric door machinery is lighter, the motor is less, the motor rotation is in a free state, which direction is lighter to rotate in which direction, therefore, the direction of the electric door switch can not be buried in the chain fixed, this fault is a deficiency, the motor is missing to normal, the fault is eliminated. The above two fault scenarios are relatively common.

Electric door failure: the electric door does not move according to the remote control or occasionally fails, the trackless electric door does not go in a straight line, the motor idles, the electric door does not stop in place, it is closed to about one meter away from the wall and automatically retreats, the door body makes abnormal noise, the door body walks slowly, the power is insufficient, the door body does not move according to the control box, and everything else is normal. Here's how to deal with it:

1. The electric door does not move according to the remote control or occasionally fails. The main cause of this problem is the low battery of the remote control or its aging age. Solution: Replace the battery or remote control.

2. The trackless electric door does not go in a straight line. If the trackless door cannot be opened and closed for a short distance for a long time, you can try to open the door in place and close it again. Secondly, check whether the ground navigation magnet has fallen off or damaged, the magnet is a necessary condition for alignment, and the lack will affect the operation of the door.

Solution: Check whether the navigator is worn and off, if it is damaged, it needs to be replaced with a new accessory, which is highly encapsulated and cannot be repaired.

3. The motor is idling. Solution: Check whether the clutch is in place and whether the chain is disconnected.

4. The electric door is in place and does not stop. Workaround: Check the limit magnet and navigator.

5. Close it to about one meter away from the wall and automatically retreat. Solution: This fault is caused by damage to the magnet of the ground shutdown radar to trigger the electric door protection mechanism, and reinstall the ground fixed position magnet.

6. Abnormal sound of the door. Solution: Check whether there is structural damage, including connecting rods, door rows, etc., this accessory needs to be replaced, and the original cannot be repaired.

7. The door body walks slowly and lacks power. Solution: Check whether the voltage is insufficient and the cable is damaged.

8. Press the door body of the control box to move, and everything else is normal. Vertical grinding solution: first check the control box insurance, and then consider the fault of the electric door signal line.

How electric doors work

1. The working principle of the automatic door sensor.

When the automatic door sensor detects that someone has entered, it transmits the pulse signal to the main controller, and the main controller notifies the motor to run after judgment, and monitors the motor speed at the same time, so as to notify the motor to increase the force and enter the slow operation at a certain time. After the motor gets a certain running current, it runs in the forward direction, and transmits the power to the synchronous belt, and then the synchronous belt transmits the power to the spreader system to open the door; After the door is opened, the controller will make a judgment, and if the door needs to be closed, notify the motor to move in the opposite direction and close the door.

2. The principle of translational automatic door.

When the induction detector detects that someone has entered, it transmits the pulse signal to the main controller, and the main controller notifies the motor to run after judgment, and monitors the motor speed at the same time, so as to notify the motor to increase the force and enter the slow operation at a certain time. After the motor gets a certain running current, it runs in the forward direction, and transmits the power to the synchronous belt, and then the synchronous belt transmits the power to the spreader system to open the door; After the door is opened, the controller will make a judgment, and if the door needs to be closed, notify the motor to move in the opposite direction and close the door.
