电动门毁坏有很多原因，请不要着急，济南电动门加工厂家建议可以针对以下几点检查维修或是找专业维护售后人员

　　There are many reasons for the destruction of electric doors, please do not worry, Ji'nan electric door processing manufacturers suggest that you can check for the following maintenance, or looking for professional maintenance staff

　　1、先了解机型，品名，损坏原因，故障现象，再据此详细分析，以便做到有的放矢，对症下药，少走弯路。主要询问的内容有：何时 损坏，是否浸水，是否受过撞击，是否电压过高，是否有人改动，是否操作不当，是否遭受雷击，是否有冒烟现象，是否有异常响声等。 只有在问明原因后,才能确定下一步的检修方法及处理措施。对于雷击、浸水、冒烟、烧保险等故障机型,切不可贸然通电试机,否则将造成 机器再次受创、故障扩大。

　　1, first understand the model, name, damage reasons, the phenomenon of failure, and then detailed analysis in order to achieve a clear object, the right remedy, less detours. The main contents are: when asked whether damage, flooding, or an impact, whether the voltage is too high, if someone changes, if improper operation, whether the lightning, whether there is smoke phenomenon, whether there is abnormal sound. Only after learning the cause, in order to determine the next step of the repair methods and treatment measures. For lightning, water, smoke, fire insurance and other failure models, we must not rush the electric test machine, otherwise it will cause the machine to suffer again, failure to expand.

　　2、检查电动伸缩门控制,应仔细查看电路板上是否有元件受损。如元件断裂、发黑发黄、引脚相碰、器件松动、连线错误等。有经验 的维修人员会根据用户提供的相关信息及故障现象,准确地察看电动伸缩门可疑部位,麻利地找出故障所在。某些接触不良的故障,可在光线 较暗处观察可疑部件是否有火花产生来确定(注：某些接触不良故障,尤其是在电源通电后,因故障点接触不良而产生火花)。

　　2, check the electric retractable door control, should carefully check the circuit board whether there is damage to components. If the component fault, black hair yellow, touching, pin loosening, device connection error etc.. Experienced maintenance personnel according to the relevant information and provide users with accurate fault phenomenon, to examine the electric telescopic door suspicious position, quickly find a fault. Some faults of bad contact, whether in the light is dark to observe suspicious spark components to determine (Note: some bad contact failure, especially in the power supply of electricity, poor contact due to failure to produce sparks).

　　3、在控制系统中,大都采用了电磁继电器作为控制器件,在继电器触点切换时会产生清晰的“滴哒”声。如无声或异常,在确定继电器 驱动电器无故障后,可判定该继电器不良。

　　3, in the control system, most of the electromagnetic relay used as a control device, relay contacts in the switch will produce a clear "drop" sound. If silent or abnormal, the relay is not good after the fault of the relay drive device is determined.

　　4、指使用万能表拧到合适档位,对控制电路进行相关测量。通常采用的方式有测电压、测电路的电阻、测电流等。这是一种综合性逻 辑分析手段,可依据各种测量数据准备的找出故障原因及损坏器件。

　　4, refers to the use of universal table to the appropriate gear, the control circuit related measurements. The commonly used methods include measuring voltage, measuring circuit resistance, measuring current and so on. This is a comprehensive logic analysis method, which can be used to find out the cause of the failure and the damage of the device according to various measurement data.
