Removing the Rotor During
Power Failure
4-24 RC-6 PLUS
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.
WARNING
Never attempt to open the door while the rotor is rotating.
Never attempt to slow or stop the rotor by hand.
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
Make sure that the rotor has coasted to a complete stop. When the rotor is at
rest, it makes no sound. So listen carefully for any sound coming from the rotor
chamber.
Never attempt to override the door interlock system while the rotor is rotating.
CAUTION
Do not perform any operation not specified in this manual. If any problem is
found with your centrifuge, contact Thermo Fisher Scientific or your local
representative of Thermo Fisher Scientific products.
If the power failure continues for an extended time, and you have decided to
remove the rotor from the rotor chamber during the power failure, use the
following procedure.
The rotor needs more than 60 minutes to coast to a complete stop if the rotor
has been rotating at high speed.
1. Check that the rotor stops completely.
