VII. Troubleshooting
1. Mechanical Emergency Door Release
CAUTION
A spinning rotor can cause serious injuries when touched. In case of
power outage the rotor can still be spinning.
Do not open the centrifuge before the rotor has stopped. Do not touch the
spinning rotor. Do not brake the rotor using hands or other tools.
During a power failure, you will not be able to open the centrifuge door with the regular electric door
release� A mechanical override is provided to allow sample recovery in the case of an emergency�
This is only to be used 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 current� The braking process lasts much longer than usual�
Proceed as follows:
1�
Make sure the rotor has stopped (view port in the centrifuge door)�
2�
Pull out the power supply plug� Keep the centrifuge horizontal at all times�
3�
On the right side of the housing is one white plastic plug which can be removed from the
plate with a small flat screwdriver� Once the plug is removed it will expose the release cord�
Pull the release cord attached to it to trigger the mechanical door release� The lock releases
the centrifuge door� The centrifuge door can be opened and the samples can be removed�
Reconnect the centrifuge to the power supply� Switch on the centrifuge�
