Emergency lid release
In the event of a power failure, it is possible to manually open the centrifuge
lid.
• Switch off the mains power switch and disconnect the power cord from
the socket.
• Remove the plug (see figure, item 1) from the opening on the right side
panel, e.g. with a screwdriver.
Fig. 29: Position of the opening for the emergency lid release
• First, pull the red string to release the mechanism and then unlock the
lid lock by pulling the white string.
• Then, reinsert the plug and quit the error message by switching the
centrifuge off/on. Approximately 10 seconds after quitting the lid can be
closed again.
WARNING
Do not unlock or open the lid unless the rotor is at a standstill.
If the lid is opened via the emergency lid release system during a centrifuge
run, the centrifuge will be switched off immediately and decelerate in an
unbraked manner.
