卷帘门维护方法基本上能够掌握“措施”，但存在一定的困难，特别是在没有电路原理图的情况下，刚刚进入的许多道路经常无法启动。在这里，常见的济南卷帘门维护的基本方法可以概括为：一看，二听，三摸。

The maintenance method of rolling shutter door can basically grasp the "measures", but there are certain difficulties, especially in the absence of circuit schematic diagram, many roads just entered often cannot be started. Here, the common basic maintenance methods of Jinan rolling shutter door can be summarized as follows: look, listen and touch.

1，看看

1. Look

应注意检查电路板上组件是否损坏。如部件故障，黄发，松针，接触，设备连接错误等。有经验的维护人员将根据用户提供的相关信息和故障现象正确观察问题并快速查找故障。某些联系人可用于确定可疑组件是否产生火花。

Pay attention to check whether the components on the circuit board are damaged. Such as component failure, yellow hair, loose needle, contact, equipment connection error, etc. Experienced maintenance personnel will 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 if the suspect component is sparking.

2，听听

2. Listen

大多数卷帘门控制系统使用电磁继电器作为控制器，继电器触点开关产生明显的“滴答声”声音。静音时，在确定继电器驱动电机无故障时，可以确定继电器断开。

Most roller shutter door control systems use electromagnetic relay as the controller, and the relay contact switch produces obvious "tick" sound. When the sound is muted, it can be determined that the relay is disconnected when the relay drive motor is not faulty.

3.触摸

3. Touch

在维护中，通常还会在接通电源后与某些元件（如某些元件）进行接触。 CC，防雷，变压器，驱动二极管，感应温度是否正确，如快速加热，高温，无短路故障电路可以识别不良设备。

During maintenance, it is usually necessary to contact some elements (such as some elements) after the power is turned on. CC, lightning protection, transformer, drive diode, whether the induction temperature is correct, such as fast heating, high temperature, no short circuit fault circuit can identify bad equipment.

在卷帘门的维护中，有一些注意事项。在卷帘门的维护过程中，操作员不能在未经授权的情况下离开操作点。密切关注卷帘门的开合和实施。当卷帘门被修理时，没有人可以站立或走在门下，以防止卷帘门行程开关发生故障和发生事故。检查电路和电气设备是否损坏。如果损坏，请及时修理，以免造成不必要的麻烦。

There are some precautions in the maintenance of rolling shutter door. During the maintenance of the rolling shutter door, the operator cannot leave the operation point without authorization. Pay close attention to the opening and closing of the rolling shutter door. When the shutter door is repaired, no one can stand or walk under the door to prevent the shutter door travel switch from failure and accidents. Check the circuit and electrical equipment for damage. If it is damaged, please repair it in time to avoid unnecessary trouble.
