Determination of the tolerance band in relation to the operating
range.
Associated lag time [30] s is a reset criterion.
If a transit time is determined during initialization which is
six times > 30 s, the six-fold transit time is accepted as the lag
time.
Select the characteristic:
0 Linear
1 Equal percentage
2 Reverse equal percentage
3 SAMSON butterfly valve linear
4 SAMSON butterfly valve equal percentage
5 VETEC rotary plug valve linear
6 VETEC rotary plug valve equal percentage
7 Segmented ball valve linear
8 Segmented ball valve equal percentage
9 User-defined (defined over operating software)
Note: The various characteristics are listed in the Appendix
(section 17).
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 recommendable to limit the transit time
of the actuator to prevent it from engaging too fast in the running
process.
Code 21 has priority over Code 15.
NOTICE
The function is not activated when the fail-safe function or sole-
noid valve is triggered nor upon failure of the auxiliary power.
The time required to pass through the operating range when the
valve closes.
Code 22 has priority over Code 14.
NOTICE
The function is not activated when the fail-safe function or sole-
noid valve is triggered nor upon failure of the auxiliary power.
