Diagnostics<br />
The <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> provides two types of diagnostic information; the continuous<br />
diagnostics that require no user configuration for which no valve movement<br />
occurs and Partial Stroke Testing (PST) diagnostics that you can configure and<br />
run at any time. You can also manually run a proof test (see page 11).<br />
Partial Stroke Test Diagnostics<br />
The <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> is capable of partially stroking the valve to detect failures in the<br />
final control element assembly. The PST is configured using the pushbutton<br />
display or through ValVue <strong>ESD</strong>. Upon detection of a failure or deviation from the<br />
user configurable conditions the annunciation channel SW 1 sets its state to low.<br />
The PST can be configured to start automatically or can be initiated through<br />
setting the current input to 16.4 mA. +/- 0.1mA, local control panel pushbutton, or<br />
initiated locally by an operator. When configured to run automatically or when<br />
initiated through a safety rated logic solver, additional diagnostic credit can be<br />
taken for the PST.<br />
In addition to the safety rated I/O, HART communications are available to provide<br />
additional information on the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> status. Additional diagnostic functions<br />
include:<br />
With ASD or A/DSD modes, the device is capable of capturing and<br />
storing the shutdown event when the safety function is engaged and / or<br />
when the valve is positioned using the control signal (4-20 mA or <br />
0-24 VDC).<br />
The <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> can provide general information of the device’s sensor<br />
health (Temperature, Actuator Pressure, Air supply, Current, etc.).<br />
Capable of annunciating faults resulting from a PST.<br />
