<strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> Configurations<br />
Wiring the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong><br />
There are three possible <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> installation configurations each with a<br />
different wiring scheme.<br />
Analog Safety Demand (ASD)<br />
Discrete Safety Demand (DSD)<br />
Analog Safety Demand (ASD)<br />
Analog with Discrete Safety Demand (A/DSD)<br />
The Analog Safety Demand configuration is: 4 - 20 mA signal, power and trip<br />
signal with superimposed HART communications (Figure 13).<br />
