Implementation of new Automatic Transfer Switches in an integrated automation system for industrial precision cooling

The aim of this thesis concerns to give a general overview of the structure of a data center and to highlight the importance of a core element called ATS (Automatic Transfer Switch) installed in one of the machines used to control the data center internal temperature. More in detail, first it will be given a description of the data center environment and its cooling infrastructure. Then, it will be presented one of the machines that are used to correctly adjust the internal temperature of a data center, named Fanwall, giving a detailed overview of its technical specifications. After this, it will be discussed in detail the most important communication protocol used in the system and it will be given an overview of the Schneider Electric BMS, namely EcoStruxure. Finally, it will be presented the Automatic Transfer Switch case of study, in which it will be explained its importance in the system, then it will be described the behavior of the Fanwall in case of power outage and after this, it will be presented the two new ATS models introduced in the project and it will be exposed in detail the development process followed to introduce these two new elements in the PLC logic and the improvement introduced from the HMI point of view, to allow the users to correctly set and read the power supply status of the machine from the touch screen interface.
