Functional Description

AC Distribution
The AC distribution assembly provides On/Off power control and power
distribution to the sterilizer. It interfaces with system software to provide
AC power distribution to all subsystems including: Heaters for the
chamber, door and vaporizer; DC power supply; vacuum pump; and
plasma power supply.
The AC distribution assembly contains, inside the enclosure, a
configuration jumper board which must be set to match the input voltage
to be used by the sterilizer (120V/240V). The voltage setting of the
jumper board is determined by how the jumper board is plugged into its
socket.
DC Power Supply
The DC power supply converts AC power to six different DC voltages.
The voltages are +3.3V, +5V, +12V, +24V and +/-15V. All output
voltages are regulated and the DC power supply has built-in over-current
protection. The input to the DC power supply is supplied by AC power
from the AC distribution assembly.
System Controller
The system controller consists of the universal controller board and the
system interface board. The system software resides in the Compact-
Flash card on the universal controller board. The system controller
provides all necessary electrical interconnections to components,
provides software control to operate and monitor the sterilizer, provides
external connections and access, and provides a control interface for the
operator to input cycle information and access the sterilizer’s functions.
The system controller is configured as two circuit boards mounted
together, inside a metal shielded enclosure. This assembly is mounted at
the rear of the top module in such a way as to provide access to
connectors on the interface board through slots and cutouts in the top rear
panel.
Fan
The fan is mounted on the rear wall of the top module. The fan exhausts
heat from the top module.
