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 />
