Faults, Stops and Alarms
Normal Stop
When a normal stop is issued and the unit is running, the system will start a normal shut-down sequence.
1. To issue a normal stop, touch and hold the Run Stop icon on the display for 2 seconds.
2. On the display, the Unit State will read Cooldown, and the Cooldown state delay will begin timing
(if configured).
3. After the Cooldown is completed, the Unit State will read Stopping.
4. When everything has been recognized as back to normal, the Unit State will read Panel Ready.
Fault Shutdown
The Centurion will continually monitor for Fault or ESD shutdown events which require the equipment to
stop immediately or prevent it to start.
On the display, the Unit State will read Shutdown, and the Alarm Shutdown banner will appear on most
operating screens.
The cause of the event is recorded and can be viewed on the Shutdown History screen with time and
date of occurrence.
1. The Shutdown History screen displays information of the fault. Touch the Book icon for
troubleshooting.

2. The Shutdown Snapshot screen displays the values of the unit running at the time a fault
occurred.

3. Once the corrections are made, clear the Shutdown condition by touching the Reset icon on the
screen.
4. Always make corrections on the unit before attempting to restart the equipment.
Alarms
If an alarm condition is detected the Alarm Shutdown banner on the bottom of the screen shows the
active alarm messages in the system. Alarms may be configured as self-clearing or as requiring
acknowledgement. Self-clearing alarms will auto clear if
it’s no longer present. Alarms requiring
acknowledgement will persist until the ACK key is pressed.
