instructions.

Flow Characteristics

Applied in addition to the control valve’s inherent charac-

teristic.

Linear

Equal Percentage (of 50:1 or 30:1)

Camflex

Quick Opening (inverse of 50:1 equal percentage)

User Configurable

Tight Shut Off (0 -20% of input)

Position Auto Tune

SVI II AP performs automatic determination of the opti-

mal valve position control parameters. In addition to P, I,

D, the position algorithm uses damping, symmetry for

exhaust and fill time constants, dead zone and magni-

tude characterization parameters. Auto Tune is opti-

mized for 5% step changes with negligible overshoot.

After the Auto Tune process is completed, the user can

further adjust the positioner tuning parameters to more

conservative or to more responsive values.

Proportional gain: 0 to 5, displayed as 0 to 5000

Integral time: 0 to 100 seconds - displayed as 0 to 1000 (1/

10s)

Derivative time: 0 to 200 milliseconds

Dead Zone: 0 to +/-5% (0 to 10% deadband)

Padj: +/- 3000 (depends on P)

Beta (non-linear gain factor): -9 to +9

Stroking Time: 0 to 250 seconds

Position compensation coefficient: 1 to 20

Boost: 0 to 20

Full open position adjustment

60 to 100% of actual stop

Start Up Time (from no power)

Less than 200 ms

Minimum current to maintain HART

3.0 mA
