卷闸门在使用的过程中，总有一些问题。下面济南卷帘门厂小编就和大家分享一些常见卷帘门出现问题和排除方法。

There are always some problems with the use of rolling gates. Below, the editor of Jinan Rolling Curtain Door Factory will share with you some common problems and troubleshooting methods for rolling shutter doors.

一、接通电源所有功能皆不能动作

1、 All functions cannot be activated when the power is turned on

1.检查按钮盒接线是否松动；

1. Check if the button box wiring is loose;

2.按钮盒按键按下听是否有响声，如有响声，检查限位接线是否正常；

2. Press the button box button and listen for any sound. If there is a sound, check if the limit wiring is normal;

3.如按钮盒及限位接线均正常，还不动作，测试变压器输入及输出电源是否带电及电机接线端子是否带电，如都正常，则直接按控制箱上接触器，如电机动作则可能是控制箱电路板损坏，更换电路板；如还不动作则可能是电机或接触器损坏，直接更换电机或接触器；

3. If the button box and limit wiring are normal and still not working, test whether the input and output power supply of the transformer is live and whether the motor wiring terminals are live. If they are all normal, directly press the contactor on the control box. If the motor acts, it may be due to damage to the circuit board of the control box. Replace the circuit board; If it still doesn't work, it may be due to damage to the motor or contactor. Replace the motor or contactor directly;

4.检查主电源是否有故障，查看保险是否烧坏。

4. Check if the main power supply is faulty and check if the fuse is burnt out.

二、接上烟感器或温感器时门马上动作

2、 The door immediately acts when the smoke or temperature sensor is connected

1.检查消防烟感或温感的信号线正负极是否接反或短路；

1. Check whether the positive and negative poles of the signal wires for fire smoke or temperature sensors are connected in reverse or short circuited;

2.可能控制箱电路板出故障，直接更换电路板故障现象。

2. It is possible that the control box circuit board has malfunctioned and the circuit board may be replaced directly.

三、控制箱报警

3、 Control box alarm

1.检查按钮盒接线是否松动；

1. Check if the button box wiring is loose;

2.检查电机线连接是否松动。

2. Check if the motor wire connection is loose.

四、消防控制室给信号卷帘不动作

4、 The fire control room signals that the roller shutter does not operate

1.检查消防信号线是否连接正常；

1. Check if the fire signal line is connected properly;

2.检查卷帘手动是否动作；

2. Check if the manual operation of the roller shutter is working;

3.更换控制箱电路板。
