济南地库冬季防风卷帘门故障排查：不落或自动升起？这样解决

　　Troubleshooting of winter windproof rolling shutter door in Jinan basement: does it not fall or automatically rises? This is how to solve it

　　冬季济南地库的防风卷帘门、快速自动门是保温防风的关键设备，但不少用户会遇到门不落、落一半自动升起的故障，既影响通行，又导致地库热量流失。这类故障多由碰撞、部件偏移或参数异常引发，并非难以解决。今天就为大家科普实用排查方法，帮济南用户快速搞定门体故障，恢复正常使用。

　　The windproof rolling shutter doors and fast automatic doors in Jinan underground warehouses during winter are key equipment for insulation and windproof. However, many users may encounter faults such as doors not falling or automatically lifting halfway down, which not only affects traffic safety but also leads to heat loss in the underground warehouses. These types of faults are often caused by collisions, component offsets, or abnormal parameters, and are not difficult to solve. Today, we will popularize practical troubleshooting methods to help Jinan users quickly solve door faults and restore normal use.

　　遇到门不落或自动升起的情况，可以排除简单的操作问题。先检查急停按钮是否被误按，若急停处于按下状态，门体将无法正常运行，恢复急停按钮后再尝试启动；同时观察门体控制面板的代码，若数字频繁变动却不执行指令，大概率不是操作失误，而是需要进一步排查硬件或参数问题。

　　When encountering situations where the door does not fall or automatically rises, simple operational issues can be ruled out first. First, check if the emergency stop button has been pressed incorrectly. If the emergency stop button is pressed, the door will not function properly. After restoring the emergency stop button, try to start it again; At the same time, observe the code of the door control panel. If the numbers frequently change but instructions are not executed, it is likely not an operational error, but further investigation of hardware or parameter issues is needed.

　　红外对射系统异常是常见诱因之一。地库门的红外对射装置负责检测通行障碍，若反光镜片未竖直、对射未对齐，或插头松动，门体为避免碰撞会拒绝下落，甚下落中自动升起。可以先观察红外对射的反光镜片是否偏移，轻轻调整竖直状态；再检查红外电源插头是否插紧，若拔掉插头后门体能正常下落，说明红外对射存在校准问题，重新对齐镜片并插好插头即可恢复。

　　Abnormal infrared radiation system is one of the common causes. The infrared reflecting device of the basement door is responsible for detecting passage obstacles. If the reflective lens is not vertical, the reflecting is not aligned, or the plug is loose, the door body will refuse to fall to avoid collision, and even automatically rise during falling. You can first observe whether the infrared reflective lens is offset and gently adjust it to a vertical position; Recheck if the infrared power plug is securely plugged in. If the door can fall normally after unplugging the plug, it indicates that there is a calibration issue with the infrared beam. Re align the lens and plug it in to restore it.

　　门体皮带松紧度也会影响运行。若门体曾被车辆碰撞，可能导致传动皮带松动，出现运行时鼓包、受力不均的情况，进而引发门体升降异常。此时需调整皮带松紧度，让皮带保持适度张力，避免因传动打滑导致门体无法精准到位，或下落中因受力不稳自动回升。

　　The tightness of the door belt can also affect its operation. If the door has been hit by a vehicle before, it may cause the transmission belt to loosen, resulting in bulging and uneven force during operation, which in turn can cause abnormal lifting and lowering of the door. At this point, it is necessary to adjust the tightness of the belt to maintain a moderate tension, in order to avoid the door body being unable to be accurately positioned due to transmission slippage, or automatically rebounding due to unstable force during descent.

　　上下限位参数偏移是碰撞后常见的核心故障。门体被撞击后，电机的上下限位设置可能错位，导致门体落到地面后仍继续下行，触发保护机制自动升起，或上升到预设高度前就停止。排查时可将门体切换手动模式，通过控制面板的菜单键进行调整：长按菜单键六秒，待显示“L1”（下限）时，按下降键让门体落到地面，松开后按确认保存；再切换“L0”（上限），按上升键调整合适高度后确认，完成参数校准。调整后，电机能精准识别升降终点，避免因限位错误引发故障。

　　The deviation of upper and lower limit parameters is a common core fault after collision. After the door is hit, the upper and lower limit settings of the motor may be misaligned, causing the door to continue to descend after falling to the ground, triggering the protection mechanism to automatically rise, or stop before reaching the preset height. When troubleshooting, the door can be switched to manual mode and adjusted through the menu button on the control panel: long press the menu button for six seconds, wait for the display of "L1" (lower limit), press the down button to let the door fall to the ground, release it, and press confirm to save; Switch to "L0" (upper limit) again, press the up button to adjust to the appropriate height, and confirm to complete the parameter calibration. After adjustment, the motor can accurately identify the lifting endpoint, avoiding faults caused by limit errors.

　　需要注意的是，排查时要遵循“从简单到复杂”的逻辑，先排除急停、红外等易操作的问题，再调整皮带和限位参数，避免盲目拆卸导致二次损坏。若门体碰撞严重，出现轨道变形、电机异响等情况，不建议自行处理，需联系维修人员检修。

　　It should be noted that during troubleshooting, the logic of "from simple to complex" should be followed. First, easy to operate problems such as emergency stop and infrared should be eliminated, and then the belt and limit parameters should be adjusted to avoid blind disassembly and secondary damage. If the door collision is severe, resulting in track deformation, motor abnormal noise, etc., it is not recommended to handle it by oneself, and professional maintenance personnel should be contacted for inspection.

　　Manufacturer's professional maintenance suggestions

　　针对济南冬季地库门的使用场景，建议定期做好维护：冬季来临前检查红外对射的校准状态、皮带松紧度和上下限位参数，避免低温环境下部件故障；若门体发生碰撞，及时排查上述部位，避免小问题恶化；选择产品时优先考虑带防撞保护和参数自校准功能的门体，降低故障概率。出现故障时切勿强行反复启动门体，以免损坏电机或传动部件，可按排查步骤操作，或联系厂家售后获取技术支持。

　　For the usage scenario of Jinan's winter underground warehouse gate, it is recommended to regularly maintain it: check the calibration status of infrared radiation, belt tightness, and upper and lower limit parameters before winter arrives to avoid component failures in low-temperature environments; If there is a collision with the door, promptly check the above parts to avoid minor problems from worsening; When selecting products, prioritize door bodies with collision protection and parameter self calibration functions to reduce the probability of failure. When a malfunction occurs, do not forcefully restart the door repeatedly to avoid damaging the motor or transmission components. You can follow the troubleshooting steps or contact the manufacturer's after-sales service for technical support.
