SVI II ESD Maintenance

Repairs may be made only by the factory authorized personnel trained to repair Safety

Devices.

1. A conservative approach is taken in estimating the service interval for the digital valve

controller in Safety Instrumented Systems. For SIS applications, perform preventive

maintenance on the SVI II ESD after five years from the shipment date, if the average daily

ambient temperature is below 60°C (140°F). Where ambient temperature exceeds 60°C

(140°F) for extended periods, reduce this maintenance interval based on plant experience.

2. SVI II ESD preventive maintenance consists of replacing gaskets, O-rings in the device and

a visual inspection of moving components to verify satisfactory condition. Following

maintenance, the SVI II ESD must be reinstalled on the valve actuator and calibrated per

the procedures. After calibration, validate the SVI II ESD functional safety. All maintenance

procedures must be performed only by the factory authorized personnel trained to repair

Safety Devices.

3. If alarms or alerts are detected during operation, maintenance or periodic inspection and

test, immediately take corrective action according to the troubleshooting and repair

procedures given in the Instruction Manual.

4. The tools required for repair of the SVI II ESD are also listed in the SVI II ESD Instruction

Manual, EW5000-ESD.

Report any failures detected that compromise functional safety to the factory. Contact your

local the factory service representative. Sales Office locations are listed on the back cover of

this document.
