2.3 Emergency procedures
Introduction
This section describes how to shut down the ÄKTA go instrument in an emergency situ-
ation, and the procedure for restarting the system.
The section also describes the result in the event of power failure.
Emergency shutdown
To shut down the instrument in an emergency, disconnect the instrument power cord
from its power source. The power source can be an ordinary power outlet, or an UPS
(Uninterruptible Power Supply) unit.
Any ongoing activity will be terminated immediately. Run data up to the time of the in-
terruption will be saved.
NOTICE
Do not leave the instrument in an emergency stop condition. Flush
the flow path with water or buffer when the emergency has been
dealt with.
Power failure
The result of a power failure depends on whether the system is equipped with a Real-Time
Unit and whether the instrument or the computer is affected.
If power is lost to the ÄKTA go instrument, with or without a Real-Time Unit, the run is
interrupted immediately. Run data collected up to the time of the power failure is saved
in the UNICORN software.
If power is lost to the computer and the system is not equipped with a Real-Time Unit,
the run is interrupted immediately. Run data collected up to the time of the power failure
is saved in the UNICORN software.
If power is lost to the computer and the system is equipped with a Real-Time Unit, the
run continues to completion and the run data is stored in the Real-Time Unit and uploaded
to the computer once it is reconnected.
Connecting the instrument and computer to an uninterruptible power supply
(UPS) can help to prevent loss of data and material during a power failure.
