Monitoring of dynamic control valve behavior 'b.\\DEVI' (Page 168)
parameter is activated.
0.0 ... 100.0
This value in percent provides information about the current dynam‐
ically determined deviation from the model response.
Monitoring/compensation of pneumatic leakage 'C.\\LEAK'
(Page 170) parameter is activated.
0 ... 100
This diagnostics parameter shows the current leakage indicator.
Monitoring of stiction (slipstick) 'd.\\STIC' (Page 173) parameter is
activated.
0.0 ... 100.0
This diagnostics parameter shows the filtered value of the slip
jumps in percent resulting from the stiction.
Monitoring of lower endstop 'F.\\ZERO' (Page 176) parameter is
activated.
'39.YCLS' Tight closing/fast closing with manipulated variable
(Page 153) Parameter is set to one of the following values: 'do', 'uP
do', 'Fd', 'Fu Fd', 'uP Fd', 'Fu do'
0.0 ... 100.0
Indication of how many percent the lower endstop has changed
compared to its value during initialization.
