O4.FACT3 - Factor 3
Adjustment range: 0.1 ... 40.0
Purpose: Use this sub-parameter to set the factor for formation of threshold 3.
Set the factor in a range from '0.1' to '40.0'. The threshold is the
product of 'O1.LIMIT' and 'O4.FACT3'.
The threshold 3 message is displayed when threshold 3 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
Factory setting: 5.0
8.3.3.12 Monitoring the position average value 'P.\\PAVG'
P. PAVG - Monitoring the position average value
Requirement: The '50.XDIAG' Activation of extended diagnostics (Page 160) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
Possible settings: ● OFF
● On
Purpose: Use this parameter to activate the test to calculate and monitor the
average value of position. During the test, the average values of
position and reference are always compared at the end of a time
interval.
The current value is displayed in Diagnostic value '20.PAVG - Aver‐
age value of position' (Page 265). The positioner triggers a mes‐
sage if the current average value of position undershoots one of the
three thresholds.
Factory setting: OFF
P1.TBASE - Time basis of average value generation
Possible settings: 0.5h / 8h / 5d / 60d / 2.5y
Purpose: Use this sub-parameter to set the time interval to calculate the
average value of position. The following values are available to
define the time intervals:
● 30 minutes
● 8 hours
● 5 days
● 60 days
● 2.5 years
After starting the calculation for average value of reference and
expiry of the time interval, a position average over the interval pe‐
riod is determined and compared with the average value of refer‐
ence. The test is then restarted.
Factory setting: 0.5h
