Emergency Recovery from Power Failure
Rotation of Rotor
The rotating rotor coasts free and finally stops if a power failure occurs during operation. When the
power is restored, the centrifuge automatically re-accelerates the rotor if the rotor is still rotating at 250
rpm or higher, or decelerates the rotor if the rotor is rotating under 250 rpm.
Operation Panel
During the power failure, all the displays on the display panel are off. When the power is restored, the
centrifuge will restart the control of the run with the set parameters that were in effect before the power
failure (battery-backed), and will report the occurrence of the power failure by lighting up the alarm
message.

WARNING When servicing the centrifuge, be sure to turn off the POWER switch, turn
off the distribution board of your centrifuge room, and then wait for at least three minutes
before removing covers or tables from the centrifuge to avoid electrical shock hazards.
WARNING Never attempt to open the door while the rotor is rotating.
Never attempt to slow or stop the rotor by hand.
