Description of System
3.2 Properties of the position controller software
Additional function Action
Position controller with additional function
Sealing function
CUTOFF
Valve closes tight outside the control range. Specification of
the value (in %), from which the actuator is completely de-
aerated (when 0%) or aerated (when 100%).
Stroke limit
X.LIMIT
Mechanical valve piston movement only within a defined
stroke range
Signal range splitting
SPLTRNG
Splitting of the uniform signal range to two or more position-
ers
Correction line to adjust the operating characteristic
CHARACT
The process characteristic can be linearized
Insensitivity range
X.CONTROL
The position controller is initially actuated from a control dif-
ference to be defined
Effective sense of direction of the controller nominal value
DIR.CMD
Reversal of the effective sense of direction of the nominal
value
Safety position
SAFEPOS
Definition of the safety position
Limit of the control speed
X.TIME
Input of the opening and closing time for the entire stroke
Effective directional sense of the actuator
DIR.ACT
Adjustment of the effective sense of direction between aera-
tion state of the actuator and the actual position
Signal level error detection
SIG.ERROR
Check the input signals for sensor break.
Warning output on the display and start up of the safety
position (if selected)
Binary input
BINARY. IN
Switch over AUTOMATIC-MANUAL or
Start up of the safety position
Analogue feedback (option)
OUTPUT
Status signal set-point or actual value
2 binary outputs (option)
OUTPUT
Output of two selectable binary values.
User calibration
CAL.USER
Change to the factory calibration of the signal input
Hierarchical control concept for easy control on the following levels
Process control On this level switch between AUTOMATIC and MANUAL
mode.
Configuration and parameterisation On this level specify certain basic functions during start-up
and, if required, configure additional functions
