Description
Note: Codes with marked with an asterisk (*) must be enabled with Code 3 prior to configuration.
19*
Tolerance band
0.1 to 10.0 [5] % of the
operating range
ESC
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.
20*
Characteristic
0 to 9 [0]
ESC
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 (sec-
tion 13.1).
21*
Required transit time OPEN
(w ramp open)
0 to 240 s [0]
ESC
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.
22*
Required transit time
CLOSED (w ramp closed)
0 to 240 s [0]
ESC
The time required to pass through the operating range when the
valve closes.
Code 22 has priority over Code 14.
23*
Total valve travel
0 to 99 · 10
7
[0]
Exponential reading from 9999 travel
cycles onwards
RES · ESC
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.
