Common faults
The main factors contributing to the fault of remote operation of electric roll-up doors are as follows:
1Transmitting power: A larger transmitting power means a longer distance, but it consumes more electricity and is more likely to cause interference.
2Increased sensitivity: The receiver's sensitivity increases, resulting in a longer remote control distance, but it is also more susceptible to interference, which can cause inadvertent operations or uncontrolled movements.
3Antenna: The antenna is of the straight line type and is parallel to each other, with a long range for remote control but occupying a large amount of space. By stretching and straightening the antenna during use, the remote control distance can be increased.
4Height: The higher the antenna, the farther the remote control distance, but it is limited by objective conditions;
5、阻挡:目前使用的无线遥控器使用国家规定的UHF频段,其传播特性和光近似,直线传播,绕射较小,发射器和接收器之间如有墙壁阻挡将大大打折遥控距离,如 果是钢筋混泥土的墙壁,由于导体对电波的吸收作用,影响更甚。因为对电动卷帘门维修的时候,会有很多的不同的系统维护,所以安装卷帘门在操作的时候会遇 到很多的问题,当然在维修的时候也需要注意。
The following are the precautions:
(1)由于电动卷帘门维修与中央门锁、电动天线共用搭铁线,而产生一个典型故障:中央门锁不好用。开关卷帘门维修时收音机、升降器指示灯等小功率电器起作用, 结果为搭铁点搭铁不实互相连电所致。
(2)电动卷帘门的密封与防尘尤为重要:电动卷帘门内板有一层塑料防护层,其破损后会导致灰尘进入电动卷帘门内,严重时将干涉电动卷帘门维修的运动。
(3)拆装电动卷帘门维修时一定要注意正确的安装位置,其所有的螺栓连接孔为椭圆孔,定位前卷帘门维修升降一定不要发生干涉。
(4)电动卷帘门的尺寸精度将严重影响卷帘门维修升降器电机的寿命。因为导槽安装在电动卷帘门上,升降器又在导槽中运动。
电动卷帘门是以多关节活动的门片串联在一起,起动由电动机组带动,卷帘门在固定的滑道内,以门上方卷轴为中心转动上下的门。适用于商业门面、车库、商 场、医院、厂矿企业等公共场所或住宅。尤其是门洞较大,不便安装地面门体的地方起到方便、快捷开启作用。如用于车库门、商场防火卷帘门飞机库门。成都电 动卷帘门、水晶卷帘门、不锈钢通花卷帘门尽在齐创门业。
