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、開關電源開空推不上：送閘時，開空推不上應查驗預留板是不是不太好，預留板的輸出線的電阻器約為300歐母。假如引路時或短路故障應當查驗電動機的點剎車踏板是不是燒毀，或查驗預留板是不是燒毀。

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、實際操作按鍵應用不靈敏：理應先按住終止鍵，再按住復位開關，隨后按上行下行鍵。

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、開關電源控制柜或按鍵控制面板的顯示燈全亮：這時候先要查驗按鍵線是不是有短路故障狀況或某1個按鍵被碾死的將會，假如左右狀況找不到，有將會是開關電源主板接口上的集成ic損壞，這時候應拆換集成ic。留意要反衣著，（即張口沖著張口）。

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：按鍵實際操作只能上行下行或下滑：這時候先要查驗限位開關線是不是有老掉線狀況，如果沒有，有將會是主電源板壞掉。

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、實際操作按鍵不太好用或按哪些按鍵全是下滑：先要查驗主電板與備電板的聯接線排時是不是松脫

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、提升鎖控：只需在線排的第5和12的空上串連1個約1K的電阻器。

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

八、分辨電動機的優劣：電動機的三相電電阻器達47-70歐母且三相電均衡。三相不平衡將會是電動機壞掉。

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、防火卷簾門警報時，理應先讓防火卷簾門全自動降低究竟，中途不必按一切按鍵，隨后再上行下行。

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、防火卷簾門的安裝調節：在安裝調節以前先要查驗控制板、按鍵盒、卷門機、限位開關、電剎車踏板的電極連接線是不是一切正常，確定后在開展調節。

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.
