Emergency Lid Release - Sigma 1-14K Operating Manual

7.1.1

Emergency Lid Release

Version 05/2010, Rev. 1.8 of 01/09/2011- sb
Translation of the original operating manual
In the event of a power failure, it is possible to manually open the
centrifuge lid with a socket wrench (part no. 930 014, included in the
scope of supply). The opening is located in the bottom plate in the
front quarter on the left-hand side.
•
Switch the centrifuge off by actuating the mains power switch and
unplugging the mains power plug.
•
Pull the centrifuge a bit over the edge of the table and jack it up
(e.g. on wooden logs). Ensure that the centre of gravity of the
centrifuge is still located above the tabletop. If necessary, the unit
must be secured by a second person.
•
Insert the wrench for the emergency release into the hole (see fig.
7.2, item 1) and attach it to the shaft of the lid lock motor.
•
Turn the shaft carefully clockwise with the aid of the wrench until
the lid opens.
•
Remove the wrench and set the centrifuge upright again.

Do not release the lid unless the rotor is at a standstill and there is no
danger to other persons.
If the lid is opened via the emergency lid release during a centrifuge
run, the centrifuge will be switched off immediately and decelerate
without a brake.
As a general rule, the lock can be opened more easily with the
emergency lid release system if the load on it is relieved by exerting
slight pressure on the lid.
