Sealing function
CUTOFF
Valve closes tight outside the control range. Specifi-
cation of the value (in %), from which the actuator is
completely deaerated (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 standard signal range to two or more
positioners
Correction line to adjust the operating characteristic
CHARACT
The operating characteristic can be linearized
Insensitivity range
X.CONTROL
The position controller is initially actuated from a
control difference to be defined
Effective direction of the controller nominal value
DIR.CMD
Reversal of the effective 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 direction of the actuator
DIR.ACT
Adjustment of the effective direction between aeration
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
