The '50.XDIAG' Activation of extended diagnostics (Page 170) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
● OFF
● On
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 261). The positioner triggers a message
if the current average value of position undershoots one of the three
thresholds.

0.5h / 8h / 5d / 60d / 2.5y
Use this sub-parameter to set the time interval to calculate the aver‐
age 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 ex‐
piry of the time interval, a position average over the interval period
is determined and compared with the average value of reference.
The test is then restarted.
