10.2.2.16
Description of parameter 46
46. STRK - limit for monitoring the path integral (number of strokes)
Use this parameter to set the limit for the path integral. This parameter corresponds to the
profile parameter "TOTAL_VALVE_TRAVEL_LIMIT".
NOTICE
Limit overshoot
A fault message is not triggered if the set limit is exceeded. Only the
"CB_TOT_VALVE_TRAV" bit in the "CHECK_BACK" parameter is set.
The fault message is activated if the path integral exceeds the limit.
This function enables preventive maintenance of the control valve.
Note
Path integral
Use the "L" parameter in the advanced diagnostics to monitor the path integral along with the
diagnostics messages.
The factory setting is "1E9".
