PLINE_Learn_Sensitivity

The PLINE_Learn_Sensitivity parameters provide very specific adjustments to the sensitivity during the learning phase.

•Insufficient Dynamics Check: Ignores the insufficient dynamic check if not selected. Use only when there is very low process noise. PIL may not detect a plugged line condition.

•10%, 20%, and 30% Stdev. Change Check: Allows for 10, 20, or 30% change in Standard Deviation while in the learning state. If this value is exceeded, the algorithm will stay in the verifying state until the value is not exceeded.

•Three or six Sigma Mean Change Check: Allows for a three or six Sigma change in the mean while in the learning state. If this value is exceeded, algorithm will stay in the verifying state until the value is not exceeded.

•2% Mean Change Check: The mean value of the baseline calculation can not vary more than 2% during the learning or verifying states. If this value is exceeded, algorithm will stay in the verifying state until the value is not exceeded.

PLINE_Detect_Length

PLINE_Detect_Length is the length of time the algorithm uses to take the process values and calculate the dynamics to compare to the learned baseline. This value should not be longer than the PLINE_LEARNING_LENGTH to avoid false detections. The default value is one minute. The detection cycle must be larger than the macrocycle of the system.

PLINE_Detect_Sensitivity

PLINE_Detect_Sensitivity will override the “Plugged Sensitivity” value. The values for this parameter are 0%-100% change in dynamics. Low values are used in low noise processes, and high values are used in noisy processes. This value is used when detecting two lines plugged condition for DP and line plugged for AP and GP transmitters.

PLINE_Single_Detect_Sensitivity

PLINE_Single_Detect_Sensitivity will override the Plugged Sensitivity value. The allowed values for this parameter are 0%-100% change in dynamics. Low values are used in low noise processes, and high values are used in noisy processes. This value is used when detecting single line plugged condition with DP transmitters only.
