Solution: as far as possible, waterproof and regular maintenance (the automatic door of the dust level and waterproof level in the automatic door standard does not reflect).

二、 控制端到被制端的中间节点多

Two. Many intermediate nodes from the control end to the controlled end

解决方法：在电器设计时尽量减少中间节点

Solution: minimize intermediate nodes in electrical design

三、 旋转门雷达故障

Three. The malfunction of the revolving door radar

一般的两翼自动旋转门配有4个旋转门雷达，门外侧两个，门内侧两个。

The general two wing automatic revolving doors are equipped with 4 revolving door radars, two outside the door and two inside the door.

门外侧雷达的常见故障为被雨水淋湿，造成烧坏。

The common malfunction of the radar outside the door is that the rain is soaked by rain, causing burn out.

解决方法：做好防水。

The solution: waterproof.

门内侧雷达的故障。一般自动门使用方会在自动门内侧安装热风幕，热风幕离旋转门雷达太近，会对雷达产生干扰，造成雷达自激，造成自动门在间断运行模式不停。

The malfunction of the inside radar. The general automatic door user will install hot air curtain inside the automatic door, and the hot air curtain will be too close to the revolving door radar. It will cause interference to the radar, cause the radar self excitation, and cause the automatic door to keep running in intermittent mode.

解决方法：与使用方协商解决

Solution: negotiate with the user

四、 防夹传感器故障

Four, anti clamp sensor fault

一樘两翼旋转自动门在门内外侧各有一个放夹传感器，其常见故障为存在防夹死区，在夏季和冬季检测距离会发生变化。虽然符合自动门标准，但还是存在安全隐患。

A complete set of wings automatic revolving doors on each side and a clamp sensor, the common fault for the existence of anti pinch dead, in summer and winter detection distance will change. Although it is in line with the automatic gate standard, there is still a hidden danger.

解决方法：在门外壁右侧下端安装检测传感器，减小防夹死区。

The solution is to install the detection sensor at the right side of the right side of the outside wall to reduce the dead zone of the anti clamp.
