1. One of the necessary tools for installing fireproof rolling shutter doors is a ten thousand energy meter, which must be prepared. If the motor does not rotate, the first consideration is whether the voltage is normal. The normal voltage of the fireproof rolling shutter door motor is 380V, and if 220V occurs, the motor will not rotate;

2、考慮到是電壓問題的時候，檢查是不是地線和零線接反了或者去工地大電盤看看是否有其他問題；

2. When considering the voltage issue, check if the ground wire and zero wire are connected in the opposite direction or go to the construction site's large electrical panel to see if there are any other issues;

3、如果是接線正常，電壓也正常的時候，就要檢查電控設備。看控制箱輸入380v，輸出是不是也是380v;

3. If the wiring is normal and the voltage is also normal, it is necessary to check the electronic control equipment. Firstly, check if the input and output of the control box are also 380V;

4、如果是控制箱輸入輸出電壓都沒問題的時候，看看電機中的3個線圈的電阻是不是正常，因為電機轉不轉，全靠這三個線圈，三個線圈都是在50上下，如果有1-2個是1的情況，電機不會轉的；

4. If there is no problem with the input and output voltage of the control box, check if the resistance of the three coils in the motor is normal. Because the motor cannot rotate, it all depends on these three coils. All three coils are around 50. If 1-2 coils are 1, the motor will not rotate;

5、電源線中斷：檢查快速門電機接線，需要時糾正；

5. Power line interruption: Check the wiring of the fast door motor and correct it if necessary;

6、熔斷器熔斷：更換熔斷器；

6. Fuse blown: replace the fuse;

7、電機保護裝置已動作：檢查電機保護裝置的設置是否正確，需要時排除故障；

7. The motor protection device has been activated: Check if the setting of the motor protection device is correct, and troubleshoot if necessary;

8、電機接觸器不動作，控制系統中的故障：檢查電機控制器的控制，需要時排除故障。

8. Motor contactor not working, malfunction in control system: Check the control of the motor controller and troubleshoot if necessary.

9、就是看看是不是電機缺少蒸餾條，有些電機廠家，出廠檢測不仔細，就會出現個別的電機忘記放蒸餾條。蒸餾條的缺少，不會導致電機不轉，但是會出現電機吱吱響的故障。

9. It's just to see if the motor lacks distillation strips. Some motor manufacturers may forget to put distillation strips on individual motors if they don't conduct careful factory inspections. The lack of distillation strips will not cause the motor to stop rotating, but it will cause the motor to squeak.
