卷帘门运行期间十个常见的维修方面

随着经济的发展，卷帘门的应用领域愈加广泛，已经不断应用到大型超市、商场、地下车库、厂房及其他人员密集的场所，在使用过程中难免会遇到一些小问题需要解决，在此厂家总结几点常见故障及处理方法供大家参考。

With the development of economy, the application field of roller shutter door is more and more extensive, and it has been continuously applied to large supermarkets, shopping malls, underground garages, workshops and other densely populated places. It is inevitable to encounter some small problems to be solved in the process of use. Here, the manufacturer summarizes some common faults and treatment methods for your reference.

一、卷帘门不动：应检查电源，看卷帘门的电源空开是否有电，如果没电，就应线检查电源部分。如果有电，此时卷帘控制箱的电源指示灯应当是绿色常亮。如果指示灯不亮此时我们应检查控制箱内的变压器（变压器的电阻270欧姆)是否烧坏。如果电源指示灯是绿色闪烁，表明电源部分可能缺相，如果电源不缺相有可能是控制箱的备用电源板烧坏；也有可能住电源板和备用电源板都烧坏。

1、 The rolling shutter door does not move: check the power supply to see whether the power supply of the rolling shutter door is powered. If there is no power, check the power supply part. If there is electricity, the power indicator of the roller shutter control box should be green and always on. If the indicator light is not on, we should check whether the transformer in the control box (the resistance of the transformer is 270 ohms) is burnt out. If the power indicator is flashing green, it indicates that the phase of the power supply may be missing. If the phase of the power supply is not missing, the standby power board of the control box may be burned out; It is also possible that both the live power board and the standby power board are burnt out.

二、电源空开推不上：送闸时，空开推不上应检查备用板是否有问题，备用板的输出线的电阻约为300欧姆。如果开路时或短路应该检查电机的点刹车是否烧坏，或检查备用板是否烧坏。

2、 The power supply air switch cannot be pushed: when the switch is sent, if the air switch cannot be pushed, check whether there is a problem with the spare board. The resistance of the output line of the spare board is about 300 ohms. In case of open circuit or short circuit, check whether the point brake of the motor is burnt out, or check whether the spare board is burnt out.

三、操作按钮使用不灵：应当先按下停止键，再按下复位键，然后按上行下行键。

3、 The operation button does not work well: you should first press the stop key, then press the reset key, and then press the up and down keys.

四、电源控制箱或按钮面板的指示灯全亮：这时应先检查按钮线是否有短路现象或某一个按钮被压死的可能，如果以上现象不存在，有可能是电源主板上的芯片坏掉，这时应更换芯片。注意要反着装，（即开口对着开口）。

4、 The indicator lights of the power control box or button panel are all on: at this time, check whether there is a short circuit in the button line or whether a button may be crushed to death. If the above phenomenon does not exist, it may be that the chip on the power motherboard is broken, and the chip should be replaced at this time. Pay attention to reverse dressing (i.e. opening to opening).

五：卷帘门按钮操作只有上行或下行：这时应先检查限位线是否有掉线现象，如果没有，有可能是主电源板坏了。

5： The operation of the roller shutter door button is only up or down: at this time, check whether the limit line falls off. If not, it may be that the main power board is broken.

六、卷帘门操作按钮不好用或按什么按钮都是下行，应先检查主电板与备电板的连接排线时是否松动

6、 If the operation button of the rolling shutter door is not easy to use or any button is pressed, it is necessary to check whether the connecting cable between the main board and the standby board is loose

七、增加锁控：只需在排线的第5和12的空上串接一个约1K的电阻。

7、 Add lock control: just connect a resistance of about 1K in series on the air of the 5th and 12th of the flat line.

八、判断电机的好坏：电机的三相电阻达47-70欧姆且三相平衡。三相不平衡可能是电机坏了。

8、 Judge whether the motor is good or bad: the three-phase resistance of the motor is 47-70 ohms and the three-phase is balanced. The three-phase imbalance may be caused by the motor failure.

九、卷帘门报警时，应当先让卷帘门自动下降到底，途中不要按任何按钮，然后再上行。

9、 When the rolling shutter door gives an alarm, the rolling shutter door should be automatically lowered to the bottom first, and then it should not press any button on the way, and then it will go up.

十、卷帘门的安装调试：济南电动卷帘门安装维修人员认为在安装调试之前应先检查控制器、按钮盒、卷门机、行程开关、电刹车的连接线是否正常，确认后在进行调试。

10、 Installation and commissioning of rolling shutter door: the installation and maintenance personnel of Jinan electric rolling shutter door believe that before installation and commissioning, they should first check whether the connecting wires of controller, button box, door rolling machine, travel switch and electric brake are normal, and then conduct commissioning after confirmation.
