Omega CNI8DV, CNI16D, CNI8C, CNI8DH, CNI32 manual Start Auto Tune PID, Proportional Band Submenu

Page 43

If Anti Integral (Anti Windup) Submenu “Enabled”, this feature allows the error term outside the proportional band to be calculated and accumulated for integration. This may be an important feature in applications where fast response time is desirable.

START AUTO TUNE PID:

Press d 27) Display flashes ENBL or DSBL.

Press b 28) Scroll through the available selections: “Enable” or “Disable”. Press d 29) Display shows STRD stored message momentarily and then advances to CYCL only, if it was changed, otherwise press a to

advance to CYCL Cycle Time Submenu.

If “Enabled”, the controller is ready to calculate P, PI or PID parameters. The instrument performs this by activating the output and observing the delay and rate at which the Process Value changes. The setpoints must be at least 18°F or 10°C above the (PV) Process Value in order to perform Auto Tune, otherwise an error message will be displayed.

To start Auto Tune PlD select PID, enable Auto PID and enable Start PID. Sometimes Auto PID parameter needs fine tuning i.e. for each 5°F over shoot increase the Proportional Band (PB) by 15% and for each ±1°F fluctuation at the Setpoint (SP) increase reset by 20%.

Once started, display shows A.TUN with letters blinking in the rotating pattern. When auto tune stops, display will show process value. Do not perform any operations or settings before first stopping Auto Tune. Any alarms or other output is disabled during Auto Tune.

If “AUTO PID” was “DISABLED”, the display will show the following three submenus. This allows the user to manually enter values for Proportional, Reset and Rate terms corresponding to P, I, and D. It also can be used for auto PID for disabling unwanted parameter i.e. PI enter 0000 for rate.

PROPORTIONAL BAND SUBMENU:

Press d 30) Display flashes 1st digit of the previous P PRoP Proportional band value.

Press b & c 31) Press b and c buttons to enter a new “Proportional Band” value.

Press d 32) Display shows STRD stored message momentarily and then advances to REST only, if it was changed, otherwise press a to advance to REST Reset Setup Submenu.

Proportional band is in degrees of temperature or counts of process. Proportional band is defined, as the change in the instrument input to cause a 100% change in the controller output.
