Installation and<br />
Checking Actuator, Linkages, or Rotary Adapter<br />
Checking Actuator, Linkages, or<br />
Verify that the mounting has not been damaged in shipment for a pre-mounted<br />
<strong>SVI</strong> <strong>II</strong> <strong>ESD</strong>, physically inspect the actuator, linkage. Record the following<br />
information for the configuration checkout:<br />
Valve Air to Open (ATO) or Air to Close (ATC)<br />
Actuator pressure rating<br />
Actuator bench range<br />
Inherent trim characteristic of the control valve; linear, equal percentage,<br />
or other.<br />
NOTE<br />
For the aforementioned information, refer to the valve data<br />
sheet or model number of control valve.<br />
Verify Mounting and Linkage Adjustment<br />
Inspect the mounting and make any needed adjustments before running the PST<br />
Controller and checking the digital configuration.<br />
Connecting the Tubing and Air Supply<br />
NOTE<br />
When an <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> is turned on it is advisable to apply the<br />
air supply before applying the electrical input signal.<br />
This section describes the process for connecting the tubing and air supply to a<br />
single and double acting PST Controller.<br />
Pneumatic Connections<br />
The <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> is intended for use with industrial compressed air or natural gas<br />
systems only that meets the requirements of ISA standard 7.3 Supply pressure<br />
must not exceed 120 psi. A coalescing filter can be used to assure that the supply<br />
air is sufficiently free of oil, water, and particulate contaminants. Ensure that an<br />
adequate pressure relief provision is installed when the application of system<br />
supply pressure could cause peripheral equipment to malfunction. Installation<br />
must be in accordance with local and national compressed air and instrumentation<br />
codes. Table 4 provides the pneumatic connections and air supply requirements<br />
for the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong>.<br />
