5. ELECTRONIC SYSTEM ARCHITECTURE
5.1 OVERVIEW
This section describes the electronic system architecture of the
Arena Dialysis Delivery System. Some details may vary for
individual Instruments according to the options installed. While
reviewing this section it is recommended that you refer to the
Input/Output Diagrams when available that correspond to the
specific circuits being described.
Refer to the Interconnect Block Diagram in Figure 5-1 (next page)
for an overview of the electronic architecture and also to the
Interconnect Diagram at the end of this section.
Two letters identify most of the printed circuit boards. All the
connectors on the boards will be identified with these letters plus a
number.
Table 5-1. Electronic Board Identifiers
Printed Circuit Board Location Identifier
Blood Pump Controller Card Cage, Slot 5* PB
I/O Controller Card Cage, Slot 6 PD
UF-Proportioning Controller Card Cage, Slot 7* PC
Blood Pump Power Above Blood Pump(s) PF
UF-Proportioning Power Hydraulics Module PG
I/O Hydraulics Power Hydraulics Module PH
I/O Electronics Power Lower Chassis PI
Venous Line Clamp Driver Lower Chassis PK
Notes
*Blood Pump and UF-Proportioning Controller boards are
physically identical. The type of controller they become is
determined by the position of a jumper on the board and software
on the EEPROM. Refer to Sections 5.4.4 and 5.4.6.
Thin lines in Figure 5-1 are components; thick lines are printed
circuit boards.
The architecture is described starting with the input power and
continuing as it is distributed throughout the Instrument. It also
follows the flow of the water and concentrates as well as the blood
flow.
Table 5-12 at the end of this section, shows information on all
fuses used in the Instrument.
