OVERSPEED AND ROTOR IDENTIFICATION SYSTEM

NAME RATING PLATE

A 19-mm ( / -in.) structural steel armor ring acts as the primary
4
barrier, surrounded by a 13-mm (
to provide full protection for the operator.
An imbalance detector monitors the rotor during the run, causing
automatic shutdown if rotor loads are severely out of balance. At
low speeds, an incorrectly loaded rotor can cause an imbalance.
Rotor instability can also occur if the instrument is moved, or if
it is not resting level on the table or bench (see Section 4,
).
TROUBLESHOOTING
The overspeed system, which includes magnetic speed sensors in the
rotor chamber and magnets on the bottom of each rotor, continuously
monitors the rotor during centrifugation. At 1000 rpm, the system
identifies both the rotor type and maximum rotor speed and compares
the set speed with the rotor's maximum permitted speed. If the set
speed is greater than the maximum permitted speed, the SPEED rpm
display begins to flash rapidly and the rotor decelerates to a stop. The
error must be cleared and an appropriate speed entered before the run
can be continued or restarted. Throughout the run, checks are made to
ensure that the rotor does not exceed set speed. If a speed-related
problem occurs, the user message SPD will appear.
A name rating plate is affixed to the rear of the instrument. Always
mention the serial number and model number when contacting
Beckman Coulter regarding your Optima TLX ultracentrifuge.
