Question

3.Project characteristcs
The microcontroller was programmed to check a pair of infrared sensors, one for top and another for the bottom levels of the hopper with the purpose of maintaining a constant supply of cacao to the machine by a three-phase electric motor activated by a contacor SIEMENS 3RT1017 (Fig. 4).

Fig. 5. Circuit board

The infrared sensors for monitoring the cacao level (Fig. 6) consist on a pair of aligned infrared emitter and receiver, when obstructing the path between them, a change is registered by the microcontroller. It is important to mention that tests were made using wet cacao powder on the sensors and we observed that the dirt does not stick to the sensors.

All the electronics are integrated to a control panel (Fig. 7), we use a 220V/24V-1A transformer as the power supply for the electronic circuit. In order to connect this transformer to the power line any pair of the three-phase wires may be chosen.

The equipment has manual and automatic modes of operation. When it’s working on manual mode, the user must supervise the operation. This modality can be used temporarily in case of any failure or maintenance procedures.

4.desing and operation
The microcontroller checks the sensors, when the cacao hopper is empty activates the coil of the contactor SIEMENS 3RT1017 with 24 VAC, the contactor is open and the three-phase motor starts, when the hopper is filled the microcontroller stops the electric motor, when the hopper is emptied one more time this operation is repeated again (Fig. 7).

We show the electric diagram used on this project (Fig. 8),

5. Conclusions

A simple problem was solved by a reliable and economic way. The company obtained a benefit at short and long term, by the optimization of this process, there was no waste of cacao anymore and production expenses were smaller, in addition a worker could be relocated to another sector.

项目特点
控制器通过检测一对红外传感器，（一个用于是储料位的低位，另一个是储料位的高位。应该是个物位仪吧）来保证大量的可可豆不间断地传送到机器中。机器是由一个继电器（SIEMENS 3RT1017）控制的三相电机来提供动力。

用于检测物位的红外传感器是一对已经调节对准好的发射器和接收器组成。当它们中间有障碍物时，控制器内的寄存器会发生改变。非常值得一提的是，传感器上需使用潮湿的可可豆粉末，我们发现，干燥的可可豆准确性差。

所有电子器件集成在一个控制平板上，见图7，我们采用一个220V/24V-1A的变压器来给电子电路供电。为了连接变压器上的电源线，你会发现其上的三根电线。

The equipment has manual and automatic modes of operation. When it’s working on manual mode, the user must supervise the operation. This modality can be used temporarily in case of any failure or maintenance procedures.
设备具有手动和自动操作两种模式。手动工作状态下，操作人员必须手动给定操作。该模式使用与暂时设备故障或者是设备维修过程。

4desing and operation
The microcontroller checks the sensors, when the cacao hopper is empty activates the coil of the contactor SIEMENS 3RT1017 with 24 VAC, the contactor is open and the three-phase motor starts, when the hopper is filled the microcontroller stops the electric motor, when the hopper is emptied one more time this operation is repeated again (Fig. 7).
控制器监测物位传感器，当可可豆储物罐为空是，24V供电的中间继电器SIEMENS 3RT1017的线圈西河，中间继电器控制三相电机工作。当储物罐满时，控制器停止电机。如果储物罐再一次空时，操作会重复进行。

5. Conclusions

A simple problem was solved by a reliable and economic way. The company obtained a benefit at short and long term, by the optimization of this process, there was no waste of cacao anymore and production expenses were smaller, in addition a worker could be relocated to another sector.
结论
以一个可信且经济的方法解决了一个简单的问题。不论是眼前还是长远来看，公司将获得很大益处。通过优化工作程序，公司不会再浪费可可豆，同时生产成本也降低了，初次之外，一个工人可以安排到其它部门的其它岗位。

Answer 2

这是一条可可生产线上料仓控制系统的电控设备手册的一部分，其语法相当规范，由此推断应该是欧美产品。指南属于典型的科普类科技英语，阅读难度并不大，因为考虑到全球销售（到不同国家），只要是有点英语基础的人都能了解大概意思。而且你搞这一行（估计是刚参加工作），这种文章的阅读能力你必须具备（况且并不难）。
毫无恶意地劝一句：自己看吧，好吗？相信你会很快掌握的。
对了，一般来说，手册最后几页会有一些术语解释，包括缩写和其它一些类似于导读之类的东东，对你来说是个入门必读的好东东。最后，祝好运。本回答被网友采纳

你是不明白什么意思光理解就行还是要书面的
