Parameter – Readings/
values [default setting]
Description
19* Tolerance band
0.1 to 10.0 %, [5.0 %] of the
operating range, ESC
Used for error monitoring.
If the set point deviation is greater than selected tolerance band
for a time longer than the lag time [30 s], this causes the error
code 57 (control loop) to be activated.
Note: The lag time can only be set using the operator software.
20* Select characteristic
[0] to 9, ESC
Select characteristic. See section 16.
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 operator software)
21* Transit time OPEN
(w ramp OPEN)
[0] to 240 s, ESC
The entered transit time does
not apply when fail-safe
action, solenoid valve or
forced venting function are
triggered nor when the
auxiliary energy fails.
The time required to move through the operating range when
opening the valve.
This parameter can be used to increase the Min. transit time OPEN
(Code 40).
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.
22* Transit time CLOSED (w
ramp CLOSED)
[0] to 240 s, ESC
The entered transit time does
not apply when fail-safe
action, solenoid valve or
forced venting function are
triggered nor when the
auxiliary energy fails.
The time required to move through the operating range when
closing the valve.
This parameter can be used to increase the Min. transit time
CLOSED (Code 41).
Code 22 has priority over Code 14.
