5.4.1. HYDRAULIC CONNECTIONS � NOTE FVA/A1 - OPERATION AND MAINTENANCE MANUAL Please refer to the technical manual of the machine for a detailed description of the hydraulic connections. 5.4.2. CONNECTIONS TO THE ELECTRIC POWER SUPPLY Connection of the power supply cable of the machine to the electrical mains is under the responsibility and care of the customer. When performing the connection, strict compliance with the following is recommended: ! WARNING! Connection to the electrical mains must be performed exclusively by qualified personnel, fully complying with all the safety requirements prescribed by applicable standards with reference to the installation site of the machine. All connections must be made with no mains voltage present. ! WARNING!! Please refer to the technical manual of the machine in order to determine the correct polarities and connection sequence. Connecting the ground conductor poorly, or not connecting it at all, may seriously compromise the operating safety of the sterilizer. FEDEGARI declines any responsibility arising from connecting the ground conductor poorly or not at all. � NOTE Please refer to the technical manual of the machine for a detailed description of the electrical connections. 5.5. CHECKING THE INSTALLATION Before normal use of the sterilizer, it is necessary to provide a short running-in period, which consists in performing at least two complete cycles while the machine is empty. During this period, it is necessary to monitor and search for any anomalies. The machine can be introduced in the normal production cycle only after these tests have been successful. If anomalies in operation are observed, contact the manufacturer immediately. � NOTE Please refer to the technical manual of the machine for further information on the installation of the sterilizer.

FVA/A1 - OPERATION AND MAINTENANCE MANUAL 6. USE 6.1. GENERAL DESCRIPTION OF OPERATION All the main functions of the sterilizer are controlled by a process controller, which is composed of a PLC with integrated touchscreen. Its management depends on resident software, which is structured according to menus and submenus, which can be accessed only by entering suitable passwords. The access levels allowed permit to enter the menus of the software according to a preset hierarchy. The operator interacts with the machine by means of the touch-screen and manages the sterilization process according to preset programs, which can be customized according to the specific parameters. The set of main activities involved in treating the processed materials in order to sterilize them is termed sterilization process, or, more commonly, sterilization cycle or cycle. On the sterilizer, execution of a cycle leads to the evolution of a specific program on the process controller. The process controller, by means of its own operating system and of the program mentioned above, coordinates a series of actions aimed at the components and elements that control the fluids at the various temperatures and pressures. This provides the most correct and appropriate transfer of heat energy to the load according to its physical characteristics. The following main activities can be distinguished in the sterilization process: - autoclave preparation; - load sterilization; - cycle end. Each of these main activities is composed of further operating processes, simply termed phases, which vary, according to the programs selected from the menu by the operator, in terms of the values of the physical parameters that characterize the liquids/fluids involved in the process. These main activities typically comprise the following operating phases. � Autoclave preparation � Initial tests � Power-on � Product loading � Load sterilization � Program start and execution � Cycle end � Product unloading � Shutdown � NOTE Please refer to the OPERATING PHASES subsection for full details of the individual phases. 6.2. SOFTWARE STRUCTURE The software that is resident in the process controller is composed of two fundamental parts, which are known as: • PLC SOFTWARE • PANEL SOFTWARE � NOTE Operator access to the PLC software is not allowed. The operator can access the panel software only at specific access levels, which are enabled by entering appropriate passwords. Please refer to the technical manual for the characteristics and structures of the panel software. July 2005 19 / 31 ID no. 85693 Rev. 2
