<strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> Quick Start<br />
NOTE<br />
Install the Write Protect jumper on the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> terminal<br />
board for normal operation. Refer to the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong><br />
Instruction Manual SIL3, <strong>GE</strong>A18946 for further information.<br />
Normal Operation<br />
In Normal mode, the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> responds to the input signal and positions the<br />
<strong>ESD</strong> valve accordingly.<br />
In configurations where the safety function is triggered by current, when the input<br />
signal current falls below 5.6 mA, the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> de-energizes the <strong>ESD</strong> valve. In<br />
the same configuration, when the input signal current rises above 14 mA, the <strong>SVI</strong><br />
<strong>II</strong> <strong>ESD</strong> energizes the <strong>ESD</strong> valve.<br />
In configurations where the safety function is triggered by a discrete 0 - 24 VDC<br />
signal, when the input signal voltage falls below 3V, the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> de-energizes<br />
the <strong>ESD</strong> valve. In the same configuration, when the input signal voltage rises<br />
above 18 V, the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> energizes the <strong>ESD</strong> valve.<br />
Manual Operation<br />
Setup<br />
In Manual mode, the valve does not respond to the input signal. Instead it remains<br />
stable in the position that the valve was in when manual mode was entered or a<br />
new position selected by using HART or pushbutton interface. However, the<br />
Shutdown function is activated if the signal is less than 5.6 mA (ASD and A/DSD)<br />
or 3 VDC (A/DSD and DSD).<br />
In the Setup mode, you can set calibration and configuration parameters.<br />
Additionally, you can run response time tests, step response tests, and valve<br />
signatures.<br />
