Plugged Impulse Line Advanced Settings

NOTE

For most applications the above parameters are all that are needed to configure the PIL for detection.

In order to use the Advanced Set of parameters below, fully understand the underlying technology of the PIL. These parameters will fine tune the PIL to fit process conditions.

PLINE_Relearn

PLINE_Relearn allows the user to activate the learning phase of the PIL Detection Algorithm. To activate, “Relearn” must be selected. This can be used to reinstate the algorithm after a plugged line has been detected. The proper measures must be taken to clear the plug, and the process should be running normally before relearning the process. Relearning the process may also be necessary after changing parameters in the Advanced Set of parameters.

PLINE_Auto Relearn

PLINE_Auto Relearn determines whether or not the algorithm automatically changes to learning mode when the thresholds are exceeded. When the default “Enabled” is selected the algorithm will automatically relearn when the mean value changes by more than the Relearn Threshold value. If “Disabled” is selected, relearn must be started manually, see “PLINE_Relearn” on page 3-23.

PLINE_Relearn Threshold

PLINE_Relearn Threshold is a percent value of URL of the transmitter range. If the mean has changed by this value and Auto Relearn is “Enabled”, then the algorithm will automatically go into the learning state. If the Auto Relearn is “Disabled” this value is ignored. The default is 190 of the URL.

PLINE_Learning Cycle

PLINE_Learning Cycle determines the length of time the learning cycle uses to calculate the mean and standard deviation for the baseline. The default value is five minutes. If the process has a slow change in the mean over time, a longer learning cycle may provide a better baseline.
