System Base
3-4
System Power
The power system is located within the base and includes two internal DC power
supplies, integrated batteries, and an internal power manager. The power supplies
transform AC (Mains) power into the DC levels required by the system components.
The integrated batteries provide backup power in the event of AC (Mains) power loss
during use or when power needed exceeds power available.
The internal power manager monitors the power needed to run the system and
compares the power needed (load) with the power available (AC (Mains) power
capacity). If the power needed exceeds the power available, the system will switch to
battery power. The auxiliary outlet will remain powered as long as AC (Mains) power
is still available. To decrease the load, noncritical modules or pumps may be turned
off by the user. When the system power need falls below the available power limit for
at least 10 seconds, the system will automatically switch back to using AC (Mains)
power.
If the system switches to battery power, the battery alert tone will sound and the
power status indicator LED will flash. If a Perfusion Screen is open, a message
will be displayed on the CCM and posted in the Aux tab, the Power Source/Battery
Status icon will flash and display a color indicating approximate battery time available
and the approximate battery run time in minutes will be displayed above the Power
Source/Battery Status icon.
If the system switches to battery power, the battery alert tone will sound and the
power status indicator LED will flash. If the Main Screen is open, the Power Source/
Battery Status icon will flash and display a color indicating the approximate battery
time available and the approximate battery run time in minutes will be displayed
above the Power Source/Battery Status icon.
Note:
If the system is started by battery power, the auxiliary outlet will not be
available. When AC (Mains) power is connected, the auxiliary outlet is immediately
powered and, after a short delay, the system will automatically switch to AC (Mains)
power.
Battery System
Integrated batteries provide uninterruptible battery backup power in the event AC
(Mains) power is lost or when power needed exceeds power available.
During power loss, fully charged batteries will power a fully loaded System 1 for at
least 60 minutes. A fully loaded System 1 is defined as:
A combination of 6 blood pumps, from the list below:
2 roller pumps, speed set to 120 RPM while using 1/2 in (12,7 mm) I.D. x 3/32 in
(2,4 mm) wall tubing and/or speed set to 190 RPM while using 3/8 in (9,5 mm)
I.D. x 3/32 in (2,4 mm) wall tubing, properly occluded and fluid temperature of
25°C;
2 roller pumps, speed set to 100 RPM while using 1/4 in (6,4 mm) I.D. x 3/32 in
(2,4 mm) wall tubing, properly occluded and fluid temperature of 25°C;
1 roller pump, speed set to 50 RPM while using 1/4 in (6,4 mm) I.D. x 3/32 in
(2,4 mm) wall tubing, properly occluded and fluid temperature of 25°C;
1 roller pump, speed set to 30 RPM while using 8:1 dual tubing set, properly
occluded and fluid temperature of 5°C;
1 centrifugal pump, flow set to 5.0 L/min, a backpressure of 400 mmHg and fluid
temperature of 25°C;
