The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner.
0 ... 4.29E9
The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner. In contrast to Diagnostic
value '6.HOURS - Number of operating hours' (Page 256), this value
can be reset.
In order to minimize the control valve wear resulting from a poor
control quality, it makes sense to optimize the positioner's parame‐
ters. You can recognize optimum parameter settings when the val‐
ues of the Diagnostic value '44.VEN1R' / '45.VEN2R' (Page 265)
are low. Low values mean that the switching frequency of the posi‐
tioner pneumatics is also low. In order to carry out a comparison
with various parameter settings, determine the number of switching
cycles per hour. To do this, use the values of the Diagnostic value
'44.VEN1R' / '45.VEN2R' (Page 265) and '7.HOURR'. These three
parameters can be reset to enable simpler determination of the val‐
ues.
The travel is set in the '3.YWAY' Range of stroke (Page 156) pa‐
rameter.
0 ... 130
This value in mm or ° specifies the travel determined during the
initialization.
0 ... 1000
This value indicates the current UP or DOWN travel time in seconds
determined during the initialization.
