Description
Used for error monitoring
Determination of the tolerance band in relation to the operating
range.
Associated lag time [30] s is a reset criterion.
If a lag time is determined during initialization which is six times
> 30 s, the six-fold lag time is accepted as the lag time.

Note: The various characteristics are listed in the Appendix (sec-
tion 13.1).
The time required to pass through the operating range when the
valve opens.
Limitation of the transit time (Code 21 and 22):
For some applications it is better to limit the actuating speed of
the actuator to prevent it from engaging too fast in the running
process.
Code 21 has priority over Code 15.
The time required to pass through the operating range when the
valve closes.
Code 22 has priority over Code 14.
Totaled double valve travel.

Can be reset to 0 via RES.
Note: The number of travel cycles (in steps of 1000) is saved in a
non-volatile memory.
