The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner. In contrast to Diag-
nostic value '6.HOURS - Number of operating hours' (Page 211),
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
values of the Diagnostic value '44.VEN1R' / '45.VEN2R'
(Page 222) are low. Low values mean that the switching frequency
of the positioner 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 Di-
agnostic value '44.VEN1R' / '45.VEN2R' (Page 222) and
'7.HOURR'. These three parameters can be reset to enable sim-
pler determination of the values.
The travel is set in the '3.YWAY' Range of stroke (Page 157) 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 sec-
onds determined during the initialization.
The positioner is initialized and in manual mode (MAN).
