1. The fireproof rolling shutter door does not work: first check the power supply to see whether the power supply air switch of the fireproof rolling shutter door is powered on. If there is no power supply, check the power part of the wire. If there is power, the power indicator of the roller shutter control box shall be green and always on. If the indicator light is not on, check whether the transformer in the control box (transformer resistance is 270 ohms) is burnt out. If the power indicator flashes green, it indicates that the phase of the power supply may be missing. If the power supply is not lost, the standby power board of the control box may be burned out; It may also be that both the live power board and the standby power board are burned out.

2、 電源空氣開關不能推動：當開關發送時，空氣開關不能推動。，檢查備用板是否有問題。備用板輸出線的電阻約為300歐姆。斷路或短路時，檢查電機制動點是否燒壞，或檢查備用板是否燒壞。

2. Power supply air switch cannot be pushed: when the switch is sent, the air switch cannot be pushed. First, check whether there is a problem with the spare board. The resistance of the spare board output line is approximately 300 ohms. In case of open circuit or short circuit, check whether the motor braking point is burnt out, or check whether the spare board is burnt out.

3、 操作按鈕不正常：先按停止鍵，再按復位鍵，再按上下鍵。

3. The operation button is abnormal: first press the stop key, then press the reset key, and then press the up and down keys.

4、 電源控制箱或按鈕面板上的指示燈全部亮起：此時，檢查按鈕線路是否短路或按鈕是否被壓壞。如果不存在上述現象，則可能是電源主板上的芯片損壞。此時，更換芯片。注意反向修整(即從開口到開口)。

4. All indicators on the power control box or button panel are on: at this time, check whether the button circuit is short circuited or whether the button is crushed. If the above phenomenon does not exist, the chip on the power supply motherboard may be damaged. At this time, replace the chip. Pay attention to reverse trimming (i.e. from opening to opening).

5、按鈕操作只有向上或向下：此時，檢查限位線是否下降。否則，主電源板可能會損壞。

5. Button operation is only up or down: at this time, check whether the limit line drops. Otherwise, the main power board may be damaged.

6、 操作按鈕不易使用或按下任何按鈕都向下：檢查主板與備用板之間的連接電纜是否松動。

6. The operation button is not easy to use or press any button downward: first check whether the connecting cable between the main board and the standby board is loose.

7、 增加鎖定控制：只需將大約1K的電阻串聯在扁平線第5和第12的空氣上即可。

7. Add locking control: just connect a resistance of about 1K in series to the air of the 5th and 12th flat lines.

8、 判斷電機好壞：電機三相電阻47-70歐姆，三相平衡。三相不平衡可能是由電機故障引起的。

8. Judge whether the motor is good or bad: the three-phase resistance of the motor is 47-70 ohms and the three-phase is balanced. The three-phase imbalance may be caused by motor failure.

9、 防火卷簾門報警時，防火卷簾門應先自動降到底，途中不要按任何按鈕，然后再上升。

9. When the fire rolling shutter door gives an alarm, the fire rolling shutter door shall automatically lower to the bottom first, and do not press any button on the way, and then rise again.

10、 防火卷簾門安裝調試：安裝調試前，檢查控制器、按鈕盒、卷簾機、行程開關、電剎車等連接線是否正常，確認無誤后進行調試。

10. Installation and commissioning of fireproof rolling shutter door: before installation and commissioning, check whether the connecting wires such as controller, button box, rolling shutter machine, travel switch and electric brake are normal, and conduct commissioning after confirmation.
