卷帘门算是现代防火设备当中应用比较广泛的一种消防设施，因其耐火限度高，耐腐蚀等优势特点受到了广大群众的青睐。但有时卷帘门也会出现一些故障，那么卷帘门出现故障之后如何检测故障呢？下面济南卷帘门厂家为您解答。

Rolling shutter door is a kind of fire protection equipment widely used in modern fire protection equipment. Because of its high fire resistance, corrosion resistance and other advantages, it is favored by the masses. But sometimes the rolling shutter door also has some faults. How to detect the faults after the rolling shutter door has faults? Now the manufacturer of Jinan roller shutter door will answer for you.

在维修中，还经常接触通电后的某些元素等集成器件稳定性建CC，防雷管，变压器，二极管，感觉温度是否正确，如快速加热，温度高，无短路故障电路可以识别坏设备。

During maintenance, I often contact some elements after power on and other integrated devices to ensure the stability of CC, lightning protection tube, transformer, diode, and feel whether the temperature is correct, such as rapid heating, high temperature, and no short circuit fault circuit can identify bad equipment.

应仔细检查是否有元器件在电路板上的损伤。如组件故障，头发黄，固定针松动，接触，设备连接错误等。厂家表示有经验的维修人员会根据用户提供的相关信息和故障现象，正确地观察问题，迅速找到故障。一些接触可以是否光暗观察可疑元件产生火花的确定。

Carefully check whether there is any damage of components on the circuit board. Such as component failure, yellow hair, loose fixed needle, contact, wrong equipment connection, etc. The manufacturer said that experienced maintenance personnel would correctly observe the problem and quickly find the fault according to the relevant information and fault phenomenon provided by the user. Some contacts can be used to determine whether the spark generated by the suspect component can be observed in light or dark.

在电路的输入或输出，连接和控制模式逐渐清晰的系统电路。例如：一个电路的主控制板右电机关闭无输出，产生异常关闭。检测，先用交流电压等级的措施，终没有输出功率，从而控制终端连接继电器找到，然后测量继电器线圈是否与相应的控制电压;如由线圈的控制端，可以找到更好的控制电路等等，可以迅速找出故障元件，并排除。

The input or output of the circuit, connection and control mode of the system circuit are gradually clear. For example, there is no output when the right motor of the main control board of a circuit is closed, resulting in an abnormal shutdown. Test: firstly, measure the AC voltage level, and there is no output power, so the control terminal is connected to the relay to find out, and then measure whether the relay coil is connected with the corresponding control voltage; For example, better control circuits can be found at the control end of the coil, and fault components can be quickly found and eliminated.

卷帘门控制系统大多采用电磁继电器作为控制器，继电器触点开关会产生明显的“滴答”声。作为无声，在确定继电器驱动电机无故障，可以确定继电器坏。

The roller shutter control system mostly uses electromagnetic relay as the controller, and the relay contact switch will produce an obvious "tick" sound. As silent, it can be determined that the relay is broken after confirming that there is no fault in the relay drive motor.

以上就是卷帘门出现问题后的检测方法，当然，在实际应用过程中，我们会遇见各种各样的问题，这时候我们要冷静处理，顺藤摸瓜，找出问题的原因!关注我们http://xl0475.com，了解更多事项！

The above is the detection method after the rolling shutter door has problems. Of course, in the actual application process, we will encounter various problems. At this time, we should calm down and find out the cause of the problem! Follow us http://xl0475.com , learn more!
