Transducer Block

Search Stop Points

This method guides you through each step to search for the valve's mechanical stop
positions (both on the closed and open sides) by maximizing and minimizing the output
pressure to the positioner.
Setup procedure
1. AO/TB block mode check
2. Auto tuning execution: AUTO_TUNE_EXEC
❑ Standard
❑ Step by step

Control Parameter Tuning

This method helps perform control-parameter-specific tuning, from among the
parameters that can be tuned by the auto tuning function. It does not contain a help
utility for a stop point search (searching for the valve's mechanical stop positions).
1. AO/TB block mode check
2. Execution of control parameter tuning: AUTO_TUNE_EXEC

Travel Calibration

This method guides you through each step to carry out travel calibration. See the
respective descriptions in "Carrying out Tuning" on page 61.
Travel calibration procedure:
1. AO/Transducer block mode check
2. Execute travel calibration
a. 0% calibration: Adjustment of FINAL_VALUE (by moving the valve position to
the desired 0% position)
b. Execute 0% calibration: TRAVEL_CALIB_EXEC
c. Span calibration: Adjustment of FINAL_VALUE (by moving the valve position to
the desired 100% position)
d. Execute span calibration: TRAVEL_CALIB_EXEC
e. 50% calibration: Adjustment of FINAL_VALUE (by moving the valve position to
the desired 50% position)
f. Execute 50% calibration: TRAVEL_CALIB_EXEC
g. Exit
❑ Without timeout
❑ Exit
