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.

確認(rèn)接線正確后，使用500V兆歐表或振動器測試絕緣電阻；要求將電源接線子電動機的接線端子連接到機箱上，且相互絕緣電阻值不小于300MΩ；如果絕緣電阻符合要求，則可以進(jìn)行電源調(diào)試工作。打開電源，檢查"正常"指示燈是否點亮。

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.

如果它沒有點亮（控制回路已死），則應(yīng)更改電源線中的任何兩相；否則，請更改電源線。手動控制卷門的上，下，停止和限制開關(guān)。調(diào)整在無火的情況下，按下"向上"按鈕，卷簾門應(yīng)下降；按下"停止"按鈕，滾動門應(yīng)停止運行。

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.

在測試運行期間，頂部和底部之間可能會有差異。在這種情況下，您只需要更改兩個葫蘆的三相接線。然后嘗試確定與運行方向相對應(yīng)的限位是否有效（用手觸摸微動開關(guān)），當(dāng)該功能不起作用時，應(yīng)更換限位線；然后調(diào)整行程開關(guān)的位置以打開和關(guān)閉防火百葉窗門。

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.
