User Messages
If a problem occurs during operation, the appropriate diagnostic message will light and a beep will
sound to alert you to the condition. See Table 4.1 for a list of the diagnostic messages, the probable
causes, and the recommended actions.
Two kinds of diagnostic conditions can occur.
• Cautionary diagnostic messages alert you to a condition that may need attention when the run is
complete. Cautionary diagnostic messages provide information only; they do not shut down the
run in progress. Press
CLEAR to stop the light from flashing. If the condition still exists, the
diagnostic message will begin flashing again, even though the run continues.
• Shutdown diagnostic messages occur when a problem exists that prevents the run from
continuing. The diagnostic message will flash and the red
STOP key light will also flash,
indicating that the rotor is decelerating to a stop. You can press
CLEAR to stop the diagnostic
message from flashing. However, if the diagnostic condition still exists (for example, if the rotor
is out of balance), another beep will sound and the message will start flashing again.
