<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 />
