济南卷帘门调试教程：链条电机行程开关这样调，简单易懂！

　　Jinan rolling shutter door debugging tutorial: Adjusting the chain motor travel switch in this way is simple and easy to understand!

　　济南的商铺老板、小区业主们，是不是都遇到过这些糟心情况：卷帘门升一半就停、降到底还嗡嗡转个不停，甚门体磕到门框、扯断链条？其实这多半是链条电机的行程开关没调好，不用急着花钱找维修师傅，自己动手就能搞定！今天就把超实用的行程开关调试教程分享给大家，步骤清晰、操作简单，新手也能轻松学会，再也不用为卷帘门“不听话”发愁。

　　Have shop owners and community residents in Jinan all encountered these frustrating situations: rolling shutter doors stop halfway up, keep buzzing when they are lowered, and even knock against door frames or break chains? Actually, this is mostly due to the travel switch of the chain motor not being adjusted properly. Don't rush to spend money to find a repairman, you can handle it yourself! Today, I will share with you a highly practical tutorial on adjusting travel switches. The steps are clear and the operation is simple, making it easy for beginners to learn and no longer have to worry about "disobedient" rolling shutter doors.

　　先跟大家说清楚：行程开关是控制卷帘门升降停止位置的核心部件，相当于卷帘门的“刹车”，调不好不仅影响使用体验，还可能烧电机、损门体，所以调试时别瞎拧乱碰，跟着步骤来就行。

　　First of all, let me make it clear to everyone: the travel switch is the core component that controls the lifting and stopping position of the rolling shutter door, equivalent to the "brake" of the rolling shutter door. If not adjusted properly, it not only affects the user experience, but may also burn the motor and damage the door body. Therefore, do not twist or touch it randomly during debugging, just follow the steps.

　　步，先定好上行程的停止位置。调试前先通电，用遥控器操作卷帘门，让它慢慢升到你认为合适的高度——比如商铺门要完全打开，不遮挡门头；车库门要升到不影响车辆进出的位置，停稳后保持不动。这里划：别把门关升太高，避免门体脱轨；也别升太低，影响通行或采光，确定好位置后就保持门体静止，准备调开关。

　　The first step is to determine the stopping position of the upper journey. Before debugging, turn on the power and use the remote control to operate the rolling shutter door, allowing it to slowly rise to the height you think is suitable - for example, the shop door should be fully opened without blocking the door head; The garage door should be raised to a position that does not affect the entry and exit of vehicles, and kept still after coming to a stop. Key point here: Do not close the door too high to avoid derailment of the door body; Don't raise it too low, as it may affect traffic or lighting. After determining the position, keep the door still and prepare to adjust the switch.

　　第二步，调节上行程开关。找到电机侧面控制上行程的调节部件（一般是个小拨片或可旋转的螺丝，不同电机位置略有差异，找不到就看电机说明书），用手把它往前轻轻拨动，拨完后按一下遥控器的上行键，要是门不再往上动，说明上行程就调到位了。如果门还能继续升，就再微调一下拨片位置，直到按上行键门完全停住为止。

　　Step two, adjust the up travel switch. Find the adjustment component on the side of the motor that controls the upward stroke (usually a small paddle or a rotatable screw, the position of different brands of motors may vary slightly, so if you cannot find it, please refer to the motor manual), gently move it forward with your hand, and then press the up button on the remote control. If the door no longer moves upward, it means that the upward stroke has been adjusted in place. If the door can continue to rise, adjust the paddle position slightly until the door stops completely by pressing the up button.

　　第三步，设定下行程的停止位置。确认上行程调好后，按遥控器的下行键，让卷帘门自然下落，直到完全关闭、贴紧地面（商铺门要贴紧门槛，防止漏风进灰），立刻按停止键让门停下。这里一定要注意：门落到底后千万别让电机继续运转，否则容易烧电机线圈或扯断传动链条，造成不必要的损坏。

　　Step three, set the stop position for the downward stroke. After confirming the adjustment of the up stroke, press the down button on the remote control to let the rolling shutter door fall naturally until it is completely closed and tightly attached to the ground (the shop door should be tightly attached to the threshold to prevent air leakage and dust ingress), and immediately press the stop button to stop the door. Attention must be paid here: do not let the motor continue to run after the door has fallen to the bottom, otherwise it is easy to burn the motor coil or break the transmission chain, causing unnecessary damage.

　　第四步，调节下行程开关。找到电机上控制下行程的开关，慢慢转动或拨动调节部件，直到听到“咔”的一声脆响——这说明开关已经按压到位，下行程的限位就设置好了。此时再按下行键，门就不会继续往下动了，避免门体被压变形或电机过载。

　　Step four, adjust the travel switch. Find the switch on the motor that controls the downward stroke, slowly rotate or toggle the adjusting component until you hear a crisp "click" sound - this indicates that the switch has been pressed in place and the limit for the downward stroke has been set. At this point, pressing the down button again will prevent the door from continuing to move downwards, perfectly avoiding deformation of the door body or motor overload.

　　第五步，反复测试确认效果。全部调完后，多按几次上行、下行键：上行时门精准停在设定高度，下行时刚好落到底就刹车，没有卡顿、过冲的情况，就说明调试成功了。如果门还是“不听话”，就再小幅微调行程开关，直到升降动作完全符合预期。

　　Step five, repeatedly test and confirm the effectiveness. After completing all the adjustments, press the up and down keys several times: when going up, the door will accurately stop at the set height, and when going down, it will brake just when it reaches the bottom without any lag or overshoot, indicating successful debugging. If the door is still "disobedient", then slightly adjust the travel switch until the lifting action fully meets expectations.

　　补充两个小提醒：调试时别站在门体下方，防止门体突然掉落受伤；老旧电机的行程开关可能有磨损，调完后可以给调节部件滴点润滑油，延长使用寿命。其实链条电机行程开关的调试逻辑特别简单，济南的朋友们按这个步骤来，几分钟就能搞定，既省了维修费，又能让卷帘门用得更顺畅。要是调试时遇到电机没反应的情况，先检查电源和遥控器电池，排除基础问题后再调行程开关就行～

　　Finally, two small reminders should be added: do not stand under the door during debugging to prevent the door from suddenly falling and getting injured; The travel switch of old motors may have wear and tear. After adjustment, lubricating oil can be dripped onto the adjusting components to extend their service life. In fact, the debugging logic of the chain motor travel switch is very simple. Friends in Jinan can solve it in a few minutes by following this step, which not only saves maintenance costs but also makes the rolling shutter door smoother to use. If you encounter a situation where the motor does not respond during debugging, first check the power supply and remote control battery, eliminate the basic problem, and then adjust the travel switch
