The BUS systems, intended for new large installations, are made using a twisted pair, which connects the command and control devices to the actuators. The control devices are installed inside appropriate wall boxes. The actuators are installed inside the electric distribution board, junction boxes, or in direct proximity of the load. Only the BUS is connected to the control devices, while both the BUS and the power cable for the load managed, are connected to the actuators. The association between control and actuator is ensured by the configuration: the configuration allocates a unique address to the control device and the actuator in communication with each other. The BUS system is therefore very versatile: with a simple change in the configuration it is possible to change the association between the control device and the actuator. It is also very safe, power supply does not reach the control boxes. arteor INtroDUCtIoN

The design parameters are different from those of a traditional system. An electric distribution board must be installed, containing enough DIN modules for the installation of the system and its future expansion, as well as for dispersing the generated heat. The system shall therefore be installed with ducts, cables and distribution board, while the control devices shall be configured at the factory, and only taken on site once all work has been completed, preventing them from becoming dirty or being stolen. The versatility of the BUS system means that with just a few operations, it is possible to change the control points to meet the needs of the customer even after the system has been completely installed, and without the need for opening junction boxes or installing further cables.

用于大型安 装项目的母线系统是采用双绞线将操纵与控制装置接至执行机构。控制装置一般安装在箱体内部。执行机构一般安装在配电盘或接线盒的内部或者直接安装在荷载旁边。只有母线是接至控制装置,荷载所用的母线与电缆线全都是 接至执行机构。控制装置与执行机构间的接线的配置方式如下:针对相互通讯的控制装置与执行机构各分配一个唯一地址。因此,母线系统是多用途的:配置稍作改动即可改变控制装置与执行机构间的通讯。而且电源并未连至控 制箱,非常安全。

设计参数与 传统的系统有所不同。必须安装一个带有足够DIN模块的配电 盘,以用于安装与扩展系统以及散热所需。因此,系统应安装配备有线槽、线缆与配电盘等。控制箱出厂时就应配置完成,只需在完成现场其他工作后现取现用,以免弄脏或失窃。母线系统的多功能性是指,及时系统安装完成后 ,只要一些小的操作,无需打开接线盒或安装其他线缆,即可轻松改变控制点满足客户的使用要求。
