Auxiliary Lid Release; Automatic Braking After Power Restoration - Omni revvity CF-220 User Manual

3.13 AUXILIARY LID RELEASE

In case of power failure, the lid can be opened manually. If power failure occurs during
the operation of the centrifuge, the rotor may continue rotating for several minutes,
before it stops.
Before auxiliary lid release, turn off the main switch of the centrifuge
and wait until rotor fully stops. Check this by looking through the lid
window. Otherwise, injury from rotating rotor may occur!
On the bottom side of the centrifuge, behind the front right foot, there is a plastic
plug, which you pull out of the hole. There is a string fastened to the plug. Pull the
string vertically downwards to open the lid of the centrifuge. Then insert the string and
the plug back in the hole.
3.14 AUTOMATIC BRAKING AFTER POWER
RESTORATION
If power failure occurs during the operation of the centrifuge, the rotor may contin-
ue rotating for several minutes, before it stops. When power returns, the centrifuge
checks if the rotor is still rotating. If it is still rotating, then the display shows message
brE. The centrifuge begins with the automatic rotor braking, which is performed with
preset braking level. When rotor stops, displayshows error message ERROR E45 and
thus warns you, that power failure occurred during operation and the centrifugation
was interrupted. By pressing the STOP key, you exit from error display and go back to
stand-by mode. You can use the centrifuge again.
