防火卷簾門控制箱接線注意事項
防火卷簾控制箱是整個防火卷簾的技術核心部分，影響整個消防聯動系統。在這里，我想介紹一下防火卷簾控制箱接線的注意事項：
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:
1.參考接線端子接線圖了解各端子的功能和接線，的要求，然后校正接線；確認接線正確后，用500V兆歐表或搖表測試絕緣電阻；要求電源接線子電機的接線端子與外殼之間的絕緣電阻值不小于300m；如果絕緣電阻符合要求，只能進行通電調試。
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.打開電源，檢查“正常”指示燈是否亮起。如果沒有接通(控制電路沒有電源)，更換電源進線中的任意兩相；手動控制卷簾門的向上運動、向下運動、停止和行程開關的調整；
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;
如無火警，按“上”鍵，卷簾門應下降；按下“停止”按鈕，卷簾門應停止運行。試運行時，有可能是上下不匹配。此時只需隨意更換兩臺啟閉機的三相接線即可。然后試一下運行方向對應的限位是否起作用(用手直接觸摸微動開關)，不起作用就更換限位接線；然后調整行程開關的位置，使防火卷簾開關到位。
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.門體重復運轉：門體出現重復運轉現象時，首要查看門體在下降過程中是否有物體或簾體本身切斷紅外線狀況，采納相應辦法掃除。
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.
