1、 Fireproof rolling shutter door does not work: first check the switching power supply to see whether there is electricity when the switching power supply of fireproof rolling shutter door is open. If there is no electricity, check part of the switching power supply by wire. If there is electricity, the indicator light of the rolling curtain control cabinet should be emerald green. If the indicator light is not on, people should check whether the transformer (resistor 270 ohm bus of the transformer) in the control box is burned. If the indicator light is emerald green, it indicates that part of the switching power supply will be disconnected. If the switching power supply is not missing, the backup power board of the control cabinet will be burned; it will also burn both the live power board and the backup power board.

二、开关电源开空推不上：送闸时，开空推不上应查验预留板是不是不太好，预留板的输出线的电阻器约为300欧母。假如引路时或短路故障应当查验电动机的点刹车踏板是不是烧毁，或查验预留板是不是烧毁。

2、 Switching power supply can not be pushed on when opening the air: when sending the switch, first check whether the reserved plate is not very good, and the resistor of the output line of the reserved plate is about 300 ohm bus. If there is a lead or short circuit fault, check whether the brake pedal of the motor is burned, or whether the reserved plate is burned.

三、实际操作按键应用不灵敏：理应先按住终止键，再按住复位开关，随后按上行下行键。

3、 The application of actual operation keys is not sensitive: you should first press and hold the termination key, then press and hold the reset switch, and then press the up and down keys.

四、开关电源控制柜或按键控制面板的显示灯全亮：这时候先要查验按键线是不是有短路故障状况或某1个按键被碾死的将会，假如左右状况找不到，有将会是开关电源主板接口上的集成ic损坏，这时候应拆换集成ic。留意要反衣着，（即张口冲着张口）。

4、 The display lights of the switching power supply control cabinet or the key control panel are all on: at this time, first check whether the key line has a short circuit fault condition or a key is crushed. If the left and right conditions are not found, the integrated IC on the interface of the switching power supply motherboard will be damaged. At this time, the integrated IC should be removed and replaced. Pay attention to reverse clothing (i.e. opening the mouth against the opening).

五：按键实际操作只能上行下行或下滑：这时候先要查验限位开关线是不是有老掉线状况，如果没有，有将会是主电源板坏掉。

5： The actual operation of the key can only go up, down or down: at this time, check whether the limit switch line is old and dropped. If not, the main power board will be broken.

六、实际操作按键不太好用或按哪些按键全是下滑：先要查验主电板与备电板的联接线排时是不是松脱

6、 The actual operation keys are not easy to use or all the keys are sliding: first check whether the connecting line row between the main board and the standby board is loose

七、提升锁控：只需在线排的第5和12的空上串连1个约1K的电阻器。

7、 Lifting lock control: just connect a 1K resistor in series on the air of the 5th and 12th rows of the line.

八、分辨电动机的优劣：电动机的三相电电阻器达47-70欧母且三相电均衡。三相不平衡将会是电动机坏掉。

8、 Distinguish the advantages and disadvantages of the motor: the three-phase electric resistor of the motor reaches 47-70 ohm bus and the three-phase electricity is balanced. The three-phase imbalance will cause the motor to break down.

九、防火卷帘门警报时，理应先让防火卷帘门全自动降低究竟，中途不必按一切按键，随后再上行下行。

9、 When the fire rolling shutter door alarms, it should first let the fire rolling shutter door fully automatically lower. In the middle, you don't have to press all the buttons, and then go up and down.

十、防火卷帘门的安装调节：在安装调节以前先要查验控制板、按键盒、卷门机、限位开关、电刹车踏板的电极连接线是不是一切正常，确定后在开展调节。

10、 Installation and adjustment of fireproof rolling shutter door: before installation and adjustment, check whether the electrode connecting wires of control board, key box, door rolling machine, limit switch and electric brake pedal are normal, and carry out adjustment after confirmation.
