Setpoints Setup Screen

Up to 192 setpoints may be configured in the system by the Centurion Configuration Tool software. The values for the setpoints are user editable.

Setpoints are data entries used in greater than or less than comparisons of signals based on variable input types such as MPU, analog or thermocouples. The setpoint is a threshold, exception or any other out-of-limit event that can be configured to take a required action. Multiple setpoints are often applied to a process, and they may be configured as often as needed to meet changing conditions.

Common alarm and shutdown setpoints a user might have configured include:

 High shutdown (High-High)

 High warning (High)

 Low warning (Low)

 Low shutdown (Low-Low)

To edit a configured setpoint: a) Select the setpoint group submenu that requires editing.

The configuration listing provided will include a listing of all setpoints and their respective number. b) Assign numeric threshold that if crossed, triggers the setpoint. b) Adjust the sign of the threshold value as plus (+) or minus (-) by moving the cursor to the sign symbol position and use the up and down keys to toggle the sign.

NOTE: Setpoints 1-16 and 17-32 can also have debounce timing applied as a signal filter. The setpoint comparison must be sustained through this time delay to see the setpoint as true. This time filter can be used to ignore transients of short duration.
