Accessing the Rotor in Case of Power Failure
Accessing the Rotor in Case of Power Failure
WARNING
Any maintenance procedure requiring removal of a panel exposes the operator to
the possibility of electrical shock and/or mechanical injury. Therefore, turn the
power off (O) and disconnect the instrument from the main power source by
removing the Mains (power) plug from the outlet receptacle, and refer such
maintenance to qualified service personnel.
WARNING
Before performing this procedure, verify that the rotor is not spinning by listening
carefully for any noise coming from the chamber. Proceed only if the instrument
is quiet. Never attempt to override the door interlock system while the rotor is
spinning.
If the facility power fails only momentarily, the centrifuge will resume operation when the power
is restored and the rotor will return to the set speed. In the event of an extended power failure,
you may need to override the door-locking mechanism manually to remove the rotor and retrieve
your sample.
I1 /
Imbalance error
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,
lubricate the buckets according to
the rotor manual instructions.
Unlubricated pivot pins can prevent
the buckets from reaching
horizontal position, which can cause
imbalance.
— During low-temperature
runs (near –10°C), ice
forms around the door
opening
Door will not open at the
end of a run
Press firmly in several locations around
the door opening, then depress the foot
pedal again.
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.
