ADVANCED SETUP GUIDE
11.2.4.5 Diagnostic value '6.HOURS - Number of operating hours'
Display range: 0 ... 4.29E9
Purpose: The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner.
11.2.4.6 Diagnostic value '7.HOURR - Resettable operating hours counter'
Display range:
Purpose:
Description:
0 ... 4.29E9
The runtime meter is incremented every hour as soon as electric
auxiliary power is supplied to the positioner. In contrast to
Diagnos‐tic value '6.HOURS - Number of operating hours', 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' are low. Low
values mean that the switching frequency of the positioner
pneumatics is also low. In order to carry out a comparison with var‐
ious parameter settings, determine the number of switching cycles
per hour. To do this, use the values of the Diagnostic value
'44.VEN1R' / '45.VEN2R' and '7.HOURR'. These three parameters
can be reset to enable simpler determination of the values.
11.2.4.7 Diagnostic value '8.WAY - Determined travel'
Condition for
linear actuator:
Display range:
Purpose:
The travel is set in the '3.YWAY' Range of stroke parameter.
0 ... 130
This value in mm or ° speci ies the travel determined during the
initialization.
11.2.4.8 Diagnostic value '9.TUP - Travel time up' / '10.TDOWN - Travel time down'
Display range: 0 ... 1000
Purpose: This value indicates the current UP or DOWN travel time in seconds
determined during the initialization.
