The emergence of automatic doors is also a product of modern social science and technology development, and the automatic opening and closing of automatic doors can bring great convenience to people's access and save energy. However, if the automatic door is used for a long time, it will easily produce some minor faults. The following Xiaobian shares the automatic door maintenance method for everyone.
1. Understand the failure: In addition to inquiring about and understanding the situation before and after the damage of the electric door, in particular to understand the phenomenon of the moment of failure. For example, whether there has been smoke, abnormal noise, or falling, etc., and whether or not any person has dismantled and overhauled causes “human errorâ€.
2. Summarize the approximate location or range of the fault: Infer the various possible causes of the fault according to the manifestation of the fault, and gradually narrow the fault to a certain extent. Among them, we must be good at using the “optimization method†principle to analyze the entire circuit containing several unit circuits, and then analyze which unit or several unit circuits the failure may be in. In short, the more thorough understanding of the unique functions that each unit circuit plays in the entire circuit system, the more it can reduce the blindness in maintenance, and greatly improve the work efficiency of inspection and repair.
3. Analyze the reason: According to the surface phenomena that are understood in the field, try to find the circuit diagram of the faulty machine and the wiring diagram of the printed circuit board. If you can not find the relevant information of the electric door repair, you can also draw on the circuit diagram of similar models, make full use of past maintenance experience and comprehensive analysis based on the characteristics of the fault machine to identify the cause of the fault.
4. Fault finding: comparing the circuit schematic and PCB layout, after analyzing the working principle of the electric door and forming a suspicious fault point in the maintenance idea, the corresponding position should be found on the printed circuit board. The instrument performs on-road or off-road testing, compares the measured data with normal data, analyzes and gradually narrows down the fault, and finally finds fault points.
5. Try to repair the electric door: For the malfunction of the electric door to pass audition, try, try and other ways to deepen understanding of the failure of the electric door. The maintenance sequence is to turn on the power, toggle the corresponding switches and connectors, adjust the relevant knobs, and carefully listen to the sound diagram to analyze and judge the parts that may cause the fault.
6. Troubleshooting: After finding fault points, reasonable repair measures should be taken based on the characteristics of failed components or other abnormal conditions. For example, for soldering or soldering, it can be re-welded; for component failures, qualified components of the same model should be replaced; for short-circuit faults, the cause of the short circuit should be identified and eliminated.
7. Restoration and debugging: After the replacement of components and parts, it is often necessary to perform full or partial debugging of the electric door more or less.
Automatic doors have begun to slowly approach the home life, installed in the balcony and other places is also very good, more convenient access, but should pay attention to the maintenance of automatic doors, if they can deal with the failure to deal with, if the automatic door repair is not Learn the advice or find a professional for maintenance.
The above is a brief introduction for Xiaobian. If you want to know more related information, please continue to pay attention to Qijia Consulting. More exciting consultation, please stay tuned.
