a. Clear any Alarms Class A (always armed) 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 cycle.
Depending on your configuration, the Centurion will send signals to possibly 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.
