Changing Configurable Control Parameters
Open the Control Parameters window by double-clicking in the Control Diagram inside one
of the white boxes. To modify any of the configuration parameters, enter the desired value
in the appropriate box and
select “Update Controller”
to save the change.
In addition to the parameters described in section 6.5.8, the Control Parameters window
includes a value titled
“Close Valve when Setpoint <

. When the Setpoint is less
than this value, the controller will drive the valve to the fully closed position.

Strip Chart
The Strip Chart provides a real-time x-y strip chart plot of the Airflow Setpoint and
Measurement values with respect to time. The Strip Chart is a useful tool for troubleshooting
and evaluating the controller performance. The time scale (x axis) is adjustable between 10 and
300 seconds and the airflow volume scale (y axis) can either be set for auto range or bounded
by upper and lower limits.
