System Overview
2-13
The hardshell reservoir must be made of polycarbonate material with wall
thicknesses of 0.07 inches (1,8 mm) – 0.15 inches (3,8 mm). Level sensors should
be placed so that internal structures of the reservoir are more than 1 cm away from
the transducer face. The level sensors function normally with clear priming solutions
and blood of any hematocrit.
An operating mode for the module of Alert Only or Alert and Alarm is selected during
configuration. The operating mode can also be changed during a case.
In the event of an alarm, an audible dual tone alarm sounds, a message appears
on the Central Control Monitor, the level detect icon on the Central Control Monitor
flashes red and the status LED on the level module flashes red.
In the event of an alert, an audible single tone alert sounds, a message appears
on the Central Control Monitor, the level detect icon on the Central Control Monitor
flashes yellow and the status LED on the level module flashes yellow.
In the event of an alert or alarm, if a safety connection was made to a pump, a
message will also appear in the message area on the pump control panel, and the
pump will react with the response chosen.
Pressure Module
The pressure module provides the interface between
pressure transducers and the system. Each pressure
module has 2 channels. Two pressure transducers can
connect to each pressure module.
Up to 4 pressure modules can be connected to the
system at a time.
Terumo offers pressure transducers known to be
compatible for use with the pressure module.
Pressure transducers must be calibrated before use.
Pressure alarm limits, alert limits, safety connections and pump responses are set up
during configuration. Pressure information can be viewed and changed through the
Safety tab on the case screen.
The System 1 is capable of displaying pressure values between –250 mmHg and
+900 mmHg. Information is displayed on the Central Control Monitor in the perfusion
screen, in a square icon labeled mmHg.
“CAL” will be displayed if the pressure transducer requires calibration, “– – –”
is displayed at pressures less than –250 mmHg or if no pressure transducer is
connected, “999” is displayed at pressures greater than +900 mmHg. The display is
blank in the event of a module malfunction.

CAUTION:
The accuracy of the pressure information is dependent on
the specification of the pressure transducer. Always ensure the pressure
transducers used are appropriately specified for the application. Refer to
instructions for use provided with the pressure transducer for the transducer’s
specifications.
