Troubleshooting
Mechanical emergency door release
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. However, this
should be used only in emergencies and after the rotor has come to a complete stop.
WARNING The rotor can still be spinning at high speed. If touched, it can cause serious
injuries.
Always wait a few minutes 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 lid).
WARNING Never use your hand or other tools to brake the rotor.
2. Pull out the power supply plug.
3. On the left side of the housing is one white plastic plugs which you can pry out of the side plate with
a screwdriver or a knife.
Pull the release cord attached to it to trigger the mechanical lid release. The lid will open and the
samples can be removed.

4. Push the cord back into the centrifuge and mount the plug.
Reconnect the centrifuge once the power has been restored. Switch on the centrifuge. Press the OPEN key
to have the door locks operative again.
