Appendix E. Using the Pushbuttons and Digital
Interfaces

Overview

This section describes three ways to communicate, configure, and calibrate the SVI FF. The
Smart Valve Interface is truly a smart device capable of:
Streamlining the valve positioning function
Improving precision of process control
The four available communication tools listed below offer increasing levels of functionality:
Local Display and Push Buttons
ValVue

Local Display and Pushbuttons

The most basic and easiest digital interface is the local pushbutton and display option mounted
on the SVI FF. It is available at any time and provides immediate local access to most
configuration, calibration, and fault messages. It is approved for use in Explosion Proof and
Intrinsically Safe installations in Hazardous Areas.
Additionally, in Normal mode the local display scrolls sequentially displaying setpoint, pressure
and position information. The display sequences from one variable to the next every 1.5
seconds. Depending on specific SVI FF configuration details, the LCD also regularly displays
some parameter's values. You can configure the device to show the PID process variables, AO
block setpoint or other control parameter. Refer to the SVI FF DTM online help for procedures to
configure parameters.

The display is limited to values between 0 and 100. Therefore, the display
may show a value for the actual setpoint that is not valid if the setpoint is
above 100 or below 0.
