10.2 Description of parameters
SIPART PS2 with PROFIBUS communication
174
Operating Instructions, 09/2007, A5E00127926-07
The factory setting is "2.0".
O4.FACT3 - factor 3
Use this sub-parameter to set the factor for the formation of limit threshold 3. Set the factor in
a range from "0.1" to "40.0". The limit threshold is the product of "O1.LIMIT" and
"O4.FACT3".
The threshold 3 fault message is displayed when the limit threshold 3 exceeds. The process
to activate and display this fault message is described in the "XDIAG" parameter.
The factory setting is "5.0".
10.2.3.12
Description of parameter P
P. PAVG - calculation of position average
Use this parameter to activate the test to calculate and monitor the position average.
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 position and reference average values are always compared at the end
of a time interval. The positioner triggers a fault message if the current position average
exceeds a threshold.
The factory setting is "OFF".
P1.TBASE - time base for averaging
Use this sub-parameter to set the time interval to calculate the position average.
The following values are available to define the time intervals:
●
30 minutes
●
8 hours
●
5 days
●
60 days
●
2.5 years
After starting the reference average calculation and the expiry of the time interval, a position
average over the interval period is determined and compared with the reference average.
The test is then restarted.
The factory setting is "0.5 h".
