RETRIEVING YOUR SAMPLE IN CASE OF POWER FAILURE
If facility power fails only momentarily, the instrument will resume
operation when power is restored and the rotor will return to set
speed. However, if the rotor came to a complete stop, you will have
to restart the run when the power is restored. In either case, a power
outage message will be displayed on the control panel to indicate that
a power outage has occurred.

Rotor imbalance
Rotor load is severely
out of balance
Run shuts down with
maximum brake
• Make sure that tubes or bottles are
loaded symmetrically in the rotor.
• With swinging bucket rotors, remove
the buckets and lubricate the pivot
pins where the buckets contact as
described in the applicable rotor
manual. Unlubricated pivot pins can
prevent the buckets from reaching
horizontal position, which can cause
imbalance.
—
During low-tempera-
ture runs (near –10°C),
ice forms around the
door opening
Door will not open at
the end of a run
To minimize icing, wipe moisture from
the chamber, the chamber gasket and
the inner door surface before each
run. Keep the door closed as much as
possible.
