5. 1. Mechanical Emergency Lid Release
During a power failure, you will not be able to open the centrifuge lid with the regular
electric lid release. A mechanical override is provided to allow sample recovery in the case
of an emergency. However, this should be used only in emergencies and after the rotor
has come to a complete stop.
Always wait until the rotor has come to a stop without braking� The brake does not
work when there is no power. The braking process lasts much longer than usual.
Proceed as follows:
1.
Wait until the rotor has stopped. This can take several minutes. Use the view port
for visual confirmation.
2.
Pull out the power supply plug.
3.
Insert a 3 inch long wire (e.g. a staple) into the hole above the control panel.
4.
Press the centrifuge door down gently. Push the wire further into the hole until you hear
and feel the door latch unlocking.
5.
Remove the wire from the hole and open the centrifuge lid.
The samples can be removed.
