KION / KION-i
8. PC 1733 / PC 1796 Interconnection
The PC 1733 / PC 1796 I
NTERCONNECTION
connects a number of units in the KION workstation.
The only electronic functions on this PC board are
output filters and PTC resistors.
There are two versions of this PC board:
• PC 1733 on units with S/N 00125–01405.
• PC 1796 on units with S/N 01501 and higher.
Four PC boards are mounted in PC board connectors
on the upper side of the PC 1796:
• PC 1730 C
ONTROL
• PC 1737 M

9. PC 1730 Control
Controls flow, pressure, composition and concentra-
tion in the gas delivered to the patient. All ventilation
mode functionality is controlled by this unit.
PC 1730 C
contains a microprocessor that
ONTROL
executes the CON-software (CON-SW) that is stored
in a FLASH-PROM. New versions of the CON-SW
can be installed either by replacing PC 1730 or by
using the Software download tool.
The main functions of PC 1730 C
• General parameters (used or created by CON).
• Fresh gas production (excluding control of
anesthetic agent type and concentration).
• Inspiratory fresh gas control.
• Drive gas for rebreathing.
• Regulation of expiration.
General parameters
Some of the general parameters used or created by
CON are:
• Pressure: Input pressure signals from the four
pressure transducers on PC 1750 are supplied via
the A/D C
for regulation of inspiration and
ONVERTER
expiration.
• Timing: Output Insp. time and Exp. time signals
are generated. These are used by MEA to control
zeroing of the flow transducers.
• Fresh gas outlet: Input signal from the Hall sensor
in the A

• Pressure alarm: Input signal from MEA indicating
that upper pressure limit is reached. Used to stop
inspiration time and immediately start expiration
time. This will open the PEEP V
other valves in safe positions.
