防火卷帘门控制箱接线注意事项

The fire shutter control box is the technical core of the whole fire shutter, which affects the whole fire linkage system. Here, I'd like to introduce the precautions for the wiring of the fire shutter control box:

1.首先参考接线端子接线图了解各端子的功能和接线，的要求，然后校正接线；确认接线正确后，用500V兆欧表或摇表测试绝缘电阻；要求电源接线子电机的接线端子与外壳之间的绝缘电阻值不小于300m；如果绝缘电阻符合要求，只能进行通电调试。

1. First refer to the wiring diagram of the wiring terminal to understand the functions and wiring requirements of each terminal, and then correct the wiring; After confirming that the wiring is correct, test the insulation resistance with 500V megger or megger; It is required that the insulation resistance between the wiring terminal of the power connector and the housing of the motor shall not be less than 300m; If the insulation resistance meets the requirements, only power on commissioning can be carried out.

2.打开电源，检查“正常”指示灯是否亮起。如果没有接通(控制电路没有电源)，更换电源进线中的任意两相；手动控制卷帘门的向上运动、向下运动、停止和行程开关的调整；

2. Turn on the power and check whether the "normal" indicator is on. If it is not connected (the control circuit has no power supply), replace any two phases in the power incoming line; Manually control the upward movement, downward movement, stop and travel switch adjustment of the rolling shutter door;

如无火警，按“上”键，卷帘门应下降；按下“停止”按钮，卷帘门应停止运行。试运行时，有可能是上下不匹配。此时只需随意更换两台启闭机的三相接线即可。然后试一下运行方向对应的限位是否起作用(用手直接触摸微动开关)，不起作用就更换限位接线；然后调整行程开关的位置，使防火卷帘开关到位。

If there is no fire alarm, press the "up" button, and the rolling shutter door shall be lowered; Press the "stop" button and the rolling shutter door shall stop running. During commissioning, there may be a mismatch between the top and bottom. At this time, it is only necessary to replace the three-phase wiring of two hoists at will. Then try whether the limit corresponding to the running direction works (touch the microswitch directly by hand), and replace the limit wiring if it doesn't work; Then adjust the position of the travel switch so that the fire shutter switch is in place.

4.门体重复运转：门体出现重复运转现象时，首要查看门体在下降过程中是否有物体或帘体本身切断红外线状况，采纳相应办法扫除。

4. Repeated operation of door body: in case of repeated operation of door body, first check whether there is an object or the curtain body itself cuts off the infrared ray during the falling process, and take corresponding measures to remove it.
