How does the photocell on the electric door work?

Thinking of automatic electric gate, you dream about comfort and luxury, but you may be concerned about the safety of your system. You can easily clear your doubts with few notions about how safety devices work.

Operation of the photocell

To begin with, photocells on electric gates always come in pair: one transmitting photocell and one receiving photocell.

The transmitter photocell sends an invisible infrared signal to the receiver photocells’ photo-diode.

When an obstacle or a person cuts the infrared beam, the receiving sensor sends an alert to the main control unit, which stops the motors and puts the system into safety mode.

The use of infrared technology for gate photocells also prevents sunrays from interfering with the safety sensors and ensures a correct operating cycle of the gate system.

Proper mounting

Appropriated mounting and correct wiring of the photocells is essential to manage the electric gate safely and comfortably.

Even if the installation of safety devices such as photocells may not always be mandatory in a system, there are important  rules and regulations to comply with, regarding for instance how high from ground the photocells should be mounted to ensure effective safety or the need of flashing light to signal an automatic operated gate in community environments.

 

That’s why consulting with professionals such us Ascendant for advice is highly recommended when choosing and installing your electric gate to overcome any doubt about photocells’ placing and wiring to main electrical system.

Safety and maintenance of photocells sensors on electric gates

Now you have installed you electric gate perfectly, but any gate automation system always needs good maintenance and routine checks to ensure smooth and long lasting operation.

First of all, you should clean the photocells’ eye and the surrounding area for time to time, removing dust, leaves, bugs webs and cutting the grass if too high.

Also, in case you accidentally bum pinto the gate, make sure that photocells have not been misplaced and check the alignment between transmitting and receiving sensors is still steady. In the same way, you may check that electric wiring has not been damaged after a very strong storm.

电动门上的光电管是如何工作的？

想到自动电动门，您就会想到舒适和豪华，但您可能会担心系统的安全性。您只需了解一些关于安全装置如何工作的概念即可轻松消除疑虑。

光电管的操作

首先，电动门上的光电管总是成对出现：一个发射光电管和一个接收光电管。

发射器光电管向接收器光电管的光电二极管发送不可见的红外信号。

当障碍物或人切断红外光束时，接收传感器向主控制单元发出警报，主控制单元停止电机并将系统置于安全模式。

门光电管采用红外技术还可以防止阳光干扰安全传感器，并确保门系统的正确运行周期。

正确安装

光电管的适当安装和正确接线对于安全舒适地管理电动门至关重要。

即使在系统中安装光电管等安全装置可能并不总是强制性的，也有一些重要的规则和规定需要遵守，例如光电管应安装在离地面多高的位置以确保有效安全或需要闪光灯在社区环境中发出自动门信号灯。

这就是为什么在选择和安装电动门时强烈建议咨询我们 Ascendant 等专业人士的建议，以克服对光电管放置和接线到主电气系统的任何疑问。

电动门光电传感器的安全与维护

现在您已经完美地安装了电动门，但任何门自动化系统始终需要良好的维护和例行检查，以确保平稳和持久运行。

首先，您应该不时清洁光电管的眼睛和周围区域，清除灰尘、树叶、虫网并剪掉太高的草。

此外，如果您不小心撞到门上，请确保光电管没有放错位置，并检查发射和接收传感器之间的对准是否仍然稳定。以同样的方式，您可以检查电线是否在暴风雨过后没有损坏。
