Occurrences in the Event of Power Failure

DANGE R
To avoid electrical shock hazards, proceed as below when servicing the centrifuge.
1) Make sure to turn off the POWER switch and, if your centrifuge is equipped with a
three-wire power cord, turn off the distribution board of your centrifuge room. Then
wait at least three minutes before removing the covers from the centrifuge.
2) Make sure to turn off the POWER switch and, if your centrifuge is equipped with
a power cord with plug, unplug the power cord from the outlet. Then wait at least
three minutes before removing the covers from the centrifuge.
WARNI NG
Never open the door during rotation.
Never touch the rotor during rotation.
C A UTI ON
Never perform operations in a manner other than as described in this instruction
manual.
Rotation of the rotor
The rotor coasts to a stop� If power is restored when the current speed is above 500 rpm, the rotor will be automatically accelerated
to the set speed� If it is restored when the current speed is below 500 rpm, the rotor will decelerate to a stop�
Panel displays
During power failure, all the displays on the control panel are off� When power is restored, the centrifuge will restart control of the
run with the set parameters that were in effect before the power failure (battery backup), and will report the occurrence of the power
failure by lighting up the alert message�
Removing the rotor from the ultracentrifuge
First open the chamber door, then remove the rotor according to the following procedure:
1� Check that the rotor is at rest� Listen carefully for any sounds coming from the drive�
WARNI NG
It can take more than three hours for the rotor to come to a complete stop because
the rotor chamber is under vacuum.
Before opening the door, wait until the rotor comes to a stop.
2� Turn off the POWER switch and open the power circuit breaker for the ultracentrifuge�
3� Remove the four M5 hexagon head bolts which fix the front cover in place from both sides and pull down the front cover by pulling
its lower edge forward� Then remove the front cover� The upper edge of the front cover is engaged by insertion�
