Power failure
The system power is lost if the Mains power switch on the cabinet is turned off, the
mains cable disconnected or the power supply is lost.
The pump stops if the electrical power to the system is lost. All valves will immediately
revert to default positions. Any data that has not been saved at that time may be lost.
If only the system is affected by the power failure and not the computer, UNICORN will
display text saying that communication has been broken and that no data are recovered.
When power returns to normal, the system will be in End state (i.e., it will not resume the
run).
A UPS (Uninterrupted Power Supply) protects against temporary power failures by en-
abling the system to continue to operate for a limited time. A UPS is not included with
the system. Contact your local GE Healthcare representative for more information about
the options for your specific system.
NOTICE
If the compressed air is lost, all inlet and outlet valves will close and
all valves at the system front will open. The pressure is let out via
the air trap. There is no risk for the user or the system, but the
product may be damaged.
