Monitoring of the displacement integral
This parameter activates the monitoring of the displacement integral.
This function allows the preventive maintenance of the control valve,
also see chapter 4.5 “Diagnosics”, page 122.
Limit for the number of strokes
Input of the limit for the number of strokes. The parameter can be used
depending on the requirement profile of the user.
On the one hand, it is possible to enter a maximal number for the
strokes and to use factors smaller than one to receive warning
messages when a certain fraction of the maximal number is reached.
On the other hand, a minimum value can be entered for the strokes.
Factors greater than one are then used to receive warning messages
for certain limits above the minimum value. Factory setting for the limit
is 1 000 000.
Factor 1
Input of the factor for the threshold 1 error message. This factor refers
to the limit for the number of strokes. Factory setting for factor 1 is 1.0.
That means, for L1.LIMIT = 1 000 000 and factor 1 = 1.0, the first
stroke counter error message is triggered after 1 000 000 strokes.
Factor 2
Input of the factor for the threshold 2 error message. This factor refers
to the limit for the number of strokes. Factory setting for factor 2 is 2.0.
That means, for L1.LIMIT = 1 000 000 and factor 2 = 2.0, the second
stroke counter error message is triggered after 2 000 000 strokes.
Factor 3
Input of the factor for the threshold 3 error message. This factor refers
to the limit for the number of strokes. Factory setting for factor 3 is 5.0.
That means, for L1.LIMIT = 1 000 000 and factor 3 = 5.0, the third
stroke counter error message is triggered after 5 000 000 strokes.
