faults from the system. On the display, the
Unit State will read Panel Ready if no Class A shutdown condition exist.
b. Press and hold the Run/Stop key on the display for 2 seconds. This will initiate the start

prelube the equipment, check pre-starting permissives and then signal the driver to start
the equipment. Confirmation of running may be in the form of RPM signal or digital
switch input feedback. Once running signal is confirmed, the Centurion will be in a
running condition. Class B and S lockout timers will begin timing to faults that require
time lockout. Additional warmup and load permissives will be monitored as configured for
the package prior to enabling any load control.
c. After all preload permissives have been achieved, such as oil or water temperatures, and
possible minimum warmup times, the Unit State will read Loaded and will continue until
the stop button is pressed, RPM is lost or a fault condition exist.
