Section 1: Introduction
IMBALANCE DETECTOR
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 (see Section 4, TROUBLESHOOTING).
OVERSPEED AND ROTOR IDENTIFICATION SYSTEM
A rotor identification system prevents the installed rotor from running above its maximum rated
speed. During acceleration the microprocessor checks the magnetic rotor identification. If the
system identifies a rotor different than the one entered by the user, the system shuts down the run
and displays an error message.
Speed is limited to the maximum safe speed of the identified rotor.
