Slow or no rotation speed

原因主要是因为电机烧毁、线路短路，惦记负荷过大或者是停止按钮没有弹回复位等原因引起的。

The main reason is due to motor burnout, short circuit in the circuit, excessive load, or failure to reset the stop button.

解决方法：更换烧损的电机，检查路线接通，拨动限位开关的滑块使其触动开关触点，调整好开关位置。

Solution: Replace the burnt motor, check the line connection, move the slider of the limit switch to touch the switch contacts, and adjust the switch position.

控制失效：

Control failure:

当接触器的触点粘死、微动开关失效、滑块螺丝钉松、靠板移位，使滑块或螺母不能随丝杆转动而移动、限位器传动齿轮破损、按钮上、下键卡死。这是济南卷帘门安装维修中常见的问题。

When the contact of the contactor is stuck, the microswitch fails, the screw of the slider is loose, the backup plate shifts, making the slider or nut unable to move with the rotation of the screw rod, the transmission gear of the limiter is damaged, and the upper and lower buttons are stuck. This is a common problem during the installation and maintenance of Jinan rolling shutter doors.

济南卷帘门维修方法：

Jinan rolling shutter door maintenance method:

检查电路板是否有损伤。比如：固定针是不是松动，设备连接是不是错误，组建是不是故障等等。维修人员根据用户提供的现象可以迅速分析出故障，并加以检测。

Check the circuit board for damage. For example, whether the fixing pin is loose, whether the device connection is incorrect, whether the assembly is faulty, and so on. Maintenance personnel can quickly analyze and detect faults based on the symptoms provided by the user.

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 control system of roller shutter doors mostly uses electromagnetic relays as controllers, and the relay contact switches will produce a clear "tick" sound. As silent, when confirming that the relay drive motor is not faulty, it can be determined that the relay is faulty.
