S/5 Avance
2.1 Electrical system
The electrical system consists of two main computing units: the Display Unit and the Anesthesia Control board. Additional subsystems interact with these computing hosts to perform various gas delivery, ventilation, and monitoring functions.
The Display Unit handles the main user interface functions and connections to external devices. The Display Unit software run on the Windows CE operating system.
Therapy functions are handled by the Anesthesia Control board. The
Anesthesia Control board is based on the Motorola Coldfire processor with a
Nucleus operating system.
Embedded controllers are used to perform specific machine functions on subsystems like the Power Controller board and the Mixer board.
The processors communicate through serial bus channels.
The various function of the electrical system are accomplished on the following circuit boards:
•Display Unit CPU (A)
•Display Unit System Interconnect assembly (B)
•Display Connector board (C)
•Power Controller board (D)
•Anesthesia Control board (E)
•Pan Connector board (F)
•Electronic Mixer board (G)
•Ventilator Interface board (H)
•ABS Filter board (I)
•Vent Engine Connector board (J)
•MGAS Power Supply board (K)
•Light Strip board (L)
•Inrush board (M)

S/5 Avance
2.2 Power subsystem
Mains power enters the system through the AC Inlet module (A), which includes a line filter and the system circuit breaker. Mains power is routed through the Inrush (B) circuit board to the isolation transformer (C).
The isolated secondary output of the transformer is routed through fuses (D) and a second line filter (E) to the input of the Power Controller board (F). If the system is equipped with electrical power outlets, the transformer (larger size) also supplies isolated power to the electrical outlets through individual circuit breakers.
The Power Controller board interfaces with the system through:
•the Anesthesia Control board connector (G),
•the Display Connector board connector (H),
•the battery connector (I) and fan connector (J).
