SAFETY INTERLOCK SYSTEM

The safety interlock system prevents opening of the lid when the rotor is spinning.
The centrifuge does not operate until the lid is closed and the lid remains locked until the
rotor stops spinning. The "Lid Open" indicator turns on to warn the user if the lid is not closed
properly.
If power failure occurs, access to the samples is possible by opening
the lid with a special tool. Please see the manual lid opening section for
further information.

MANUAL LID OPENING

In case of a power cut or any defects, the instrument would be opened manually to be able to
get the samples.
To open the lid manually :

Power off the instrument

Insert the manual lid opening tool into the hole at the front side of the instrument.

Push the tool while keeping it vertically until the lid is opened.

After opening the lid manually, turn off and on device.
Before opening the lid manually, make sure that the rotor already
stopped spinning. Upon opening the lid, lift it by hand and observe the
rotor. If the rotor is still spinning, close the lid and wait approximately
10 minutes before repeating the operation. This operation must be
carried by someone who is informed of the danger and of the
precautions which must be undertaken.
After opening the lid manually, turn off and on device.
