What You Can Do on the Monitor

SVI II AP Monitor Screen

Positioner Operations

Signal Indicates the input analog signal expressed in % and in mA of the configured

signal range.

Position Indicates the actual valve position in % of valve opening. 0% is always closed

and 100% is open. Because the travel of a valve may exceed its nominal travel,

positions greater than 100% are possible (see “Open Stop Adjustment” on

page 61).

Setpoint In NORMAL mode, the setpoint is the target position based on the characterized

input. In MANUAL mode, it is the target position to which the SVI II AP is control-

ling the valve. The manual setpoint may be changed by dragging the lower

thumb on the position indicator.

Pressure The SVI II AP continuously monitors the actuator pressure and displays accord-

ing to the configured units (psi, bar, or kPa).

Position Indicator This shows the valve position graphically and consists of three parts:

 The upper part contains an indicator showing the value of the input

signal. In Normal mode this is the position setpoint. WARNING! - In manual

mode, this is the position that the valve moves to if normal mode is selected.

 The center green bar shows the valve position in percent. The numerical

valve position is shown in the center.

 The lower part contains an indicator (that can be dragged when active)

showing the valve setpoint. In operating mode, this is the same as the sig-

nal. In manual mode it is the valve setpoint. You can drag the indicator to

change the valve setpoint. While dragging, the number in the center bar

shows the manual setpoint that is selected when you release the indicator.
