SVI II ESD Maintenance
Repair and Replacement
Repairs may be made only by authorized personnel trained to repair Safety Devices.
CAUTION
When working on safety rated equipment appropriate risk
reduction safety measures must be in place.
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 in this Quick Start Guide or in the
SVI II
ESD Instruction Manual SIL3
,
GEA18946
. After calibration, validate the SVI II ESD
functional safety. All maintenance procedures must be performed only by
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 SIL3
,
GEA18946
.
