9.9.2.2 Transducer Block Parameters
Min. Travel time
Min. Travel Time Close: Time interval from opened to closed positions
registered during the last calibration.
Min. Travel Time Open: Time interval from closed to opened positions
registered during the last calibration.
Linearization Table
Min Number of Coordinates: Informs the minimal number of coordinates
supported by the device.
Max Number of Coordinates: Informs the maximum number of coordinates
supported by the device.
Number of Coordinates: The actual number of coordinates currently stored in
the device. Change this parameter to the intended
number of coordinates before setting up a new
curve.
DEADBAND
Deadband: Valve position dead band in general used as dead
band for the travel alert, setpoint deviation alert,
LCD position filter, close position deviation alert and
full stroke time measurement.
DEVICE_CALIB_DATE
Calibration Date: Date of the device’s last calibration. This value will
change after a successful calibration.
LIN_TYPE
Flow Type: Set the type of set point characterization curve. The
following options are available:
-
Linear
: the analog output setpoint from the analog output is
set directly to the servo PID setpoint;
-
Equal Percentage
: the analog output setpoint is used as a
parameter for the equal percentage function to set the servo
PID setpoint;
-
Quick Opening
: the analog output setpoint is used as a
parameter for the quick opening function to set the servo PID
setpoint;
-
User defined (table):
the analog output setpoint is
characterized using a table defined by the user to set the
servo PID setpoint. (
See the Characterization Curve section to
get details how to enter this table).
RATED_TRAVEL
Nominal Valve Stroke/Angle: Nominal stroke of the valve in units of OUT_SCALE.
