If the system computer is lost, it will not be possible to follow the recommended shut
down procedure. The system power should be turned off when the case is finished
by depressing the bottom of the AC (Mains) power switch.
Using Local Control upon a Central Control Monitor Failure
If the Central Control Monitor Fails During Bypass
Failures of the CCM include frozen touch screen, portions of the screen may appear
blank, the entire screen may go blank, or there may be a message “System Computer
Needs Service” displayed on the screen and/or local pump display.
CAUTION:
If the Central Control Monitor fails and does not reboot itself, do
NOT touch the CCM touch screen. Touching the CCM touch screen may cause
unexpected system responses. Only use local controls.
WARNING: Carefully follow these instructions to safely complete the case
through use of local controls. A failure to understand how to use the manual
controls in the case of a CCM failure may lead to patient harm.
WARNING:
Do not turn the system power off if the CCM fails as this will cause
all settings, device assignments, and safety connections to be lost.
WARNING:
If the CCM reboots itself during bypass, it is recommended that
caution be used when reentering the Perfusion Screen as this will cause safety
devices to turn off. If you choose to re-enter the Perfusion Screen, you must
reactivate safety devices.
WARNING: Failure to understand how to clear safety alarms through the manual
controls may lead to patient harm.
Use the local controls for roller pumps, centrifugal control unit, and electronic gas
blender. All safety systems that were active when the CCM was lost will still be
functional.
•
The roller pump and centrifugal pump speeds are controlled with the pump speed
control knob (see below) on the front of the pump.
