Monitoring The Position Average Value "P._Pavg - Siemens 6DR50 Series Operating Instructions Manual

9.4.3.12

Monitoring the position average value "P._PAVG"

P. PAVG - Monitoring the position average value
Use this parameter to activate the test to calculate and monitor the average value of position.
Configure the following settings to activate the test:
1. Set the "P. PAVG" parameter to "On". Sub-parameters to set the test parameters are
displayed. The test is activated.
2. Set the suitable parameter values in sub-parameters. The setting options available in
sub-parameters are described below.
During the test, the average values of position and reference are always compared at the
end of a time interval. The positioner triggers an error message if the current average value
of position exceeds a threshold.
The factory setting is "OFF".
P1.TBASE - Time basis of average value generation
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 period is determined and compared with the average value
of reference. The test is then restarted.
The factory setting is "0.5 h".
P2.STATE - Status of monitoring position average value
Use this sub-parameter to start the calculation for average value of position. If an average
value of reference has never been determined, the parameter value is "IdLE".
Then start the calculation by pressing the
changes from "IdLE" to "rEF". The average value of reference is calculated.
