Setup, Calibration<br />

and PST<br />

3<br />

Overview<br />

This section provides information on <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> setup and calibration procedures<br />

to ensure proper valve positioning and Partial Stroke Testing (PST).<br />

NOTE<br />

Perform the setup and calibration procedures in<br />

this section before putting the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> into<br />

operation as the SIF.<br />

<strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> Setup<br />

There are two <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> items to consider prior to actual setup and calibration:<br />

1. <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> display and pushbuttons for accessing <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> menu functions.<br />

2. <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> modes of operation.<br />

Pushbuttons and Local Display<br />

Local interface to the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> consists of the LCD alphanumeric display and<br />

pushbuttons. The <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> can be controlled locally through the<br />

device-mounted pushbuttons and digital display, shown in Figure 1 on page 13.<br />

Using the display you can read the input signal, valve position, and actuator<br />

pressure. The display sequences from one variable to the next is every 1.5<br />

seconds.<br />

Using the pushbuttons you can change operating modes at any time and step<br />

through a menu structure to perform a wide range of manual operation,<br />

calibration, configuration, and monitoring functions. The <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> provides<br />

internal diagnostics and if a fault is detected it appears on the display. ValVue<br />

<strong>ESD</strong> provides advanced diagnostic functions. The pushbuttons do not support<br />

ValVue <strong>ESD</strong> advanced diagnostics functions.<br />
