<strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> Maintenance<br />

Repair and Replacement<br />

<strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> Maintenance<br />

Repairs may be made only by authorized personnel trained to repair Safety<br />

Devices.<br />

CAUTION<br />

When working on safety rated equipment appropriate risk<br />

reduction safety measures must be in place.<br />

1. A conservative approach is taken in estimating the service interval for the<br />

digital valve controller in Safety Instrumented Systems. For SIS applications,<br />

perform preventive maintenance on the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> after five years from the<br />

shipment date, if the average daily ambient temperature is below 60° C <br />

(140° F). Where ambient temperature exceeds 60° C (140° F) for extended<br />

periods, reduce this maintenance interval based on plant experience.<br />

2. <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> preventive maintenance consists of replacing gaskets, O-rings in<br />

the device and a visual inspection of moving components to verify satisfactory<br />

condition. Following maintenance, the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> must be reinstalled on the<br />

valve actuator and calibrated per the procedures in this Quick Start Guide or in<br />

the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> Instruction Manual SIL3, <strong>GE</strong>A18946. After calibration, validate<br />

the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> functional safety. All maintenance procedures must be<br />

performed only by authorized personnel trained to repair Safety Devices.<br />

3. If alarms or alerts are detected during operation, maintenance or periodic<br />

inspection and test, immediately take corrective action according to the<br />

troubleshooting and repair procedures given in the Instruction Manual.<br />

4. The tools required for repair of the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong> are also listed in the <strong>SVI</strong> <strong>II</strong> <strong>ESD</strong><br />

Instruction Manual SIL3, <strong>GE</strong>A18946.<br />

Factory Notification<br />

Report any failures detected that compromise functional safety to the factory.<br />

Contact your local service representative. Sales Office locations are listed on the<br />

back cover of this document.<br />
