Fire shutter door control box is the core part of the whole fire shutter door technology, which affects the whole fire linkage system. Here, we will introduce the wiring precautions of the fire shutter door control box: first, please refer to the wiring diagram of the junction box to understand the function and wiring requirements of each terminal, and then conduct the wiring correctly.

确认接线正确后，使用500V兆欧表或振动器测试绝缘电阻；要求将电源接线子电动机的接线端子连接到机箱上，且相互绝缘电阻值不小于300MΩ；如果绝缘电阻符合要求，则可以进行电源调试工作。打开电源，检查"正常"指示灯是否点亮。

After confirming that the wiring is correct, use a 500V megohmmeter or vibrator to test the insulation resistance; It is required to connect the terminals of the power supply sub motor to the chassis, and the mutual insulation resistance shall not be less than 300m Ω; If the insulation resistance meets the requirements, the power supply can be debugged. Turn on the power and check whether the "normal" indicator is on.

如果它没有点亮（控制回路已死），则应更改电源线中的任何两相；否则，请更改电源线。手动控制卷门的上，下，停止和限制开关。调整在无火的情况下，按下"向上"按钮，卷帘门应下降；按下"停止"按钮，滚动门应停止运行。

If it does not light up (the control circuit is dead), any two phases in the power line should be changed; Otherwise, change the power cord. Manually control the up, down, stop and limit switches of the rolling door. Adjustment in the case of no fire, press the "up" button, the shutter door should be down; Press the "stop" button, the rolling door should stop running.

在测试运行期间，顶部和底部之间可能会有差异。在这种情况下，您只需要更改两个葫芦的三相接线。然后尝试确定与运行方向相对应的限位是否有效（用手触摸微动开关），当该功能不起作用时，应更换限位线；然后调整行程开关的位置以打开和关闭防火百叶窗门。

There may be differences between the top and bottom during the test run. In this case, you only need to change the three-phase wiring of the two hoists. Then try to determine whether the limit corresponding to the running direction is effective (touch the microswitch by hand). When the function does not work, replace the limit line; Then adjust the position of the travel switch to turn on and close the fire shutter door.
