SIL | Ex | Nuclear Services

Specific obligations must be complied with in SIL certified plant sections. For example, during commissioning and following corrective maintenance or modifications as well as at specified time intervals, proof-tests according to IEC 61508 must be performed.

AUMA service experts are certified and empowered to perform all test and maintenance interventions on the actuator.

Standard services

• Review of wiring for actuator and actuator controls
• Professional parameter setting
• Review and documentation of ESD safety function incl. tripping functions
• Review of documentation of safety-relevant signals
• Performance of proof tests including compilation and handover of proof test documentation for each SIL capable AUMA product in compliance with IEC 61508
• Performance of tests and functional tests
• Maintenance and replacement of wear parts
• Implementation of required performance improvements

Optional services

• Minor modifications of safety function
• Enabling and setting of special parameters, e.g. positioner, process controller, optimisation parameters, interlocks

Within the EU, devices in potentially explosive atmospheres must be checked every three years in compliance with ATEX or IEC 60079-17. This is the case for example for digestion towers in sewage water treatment plants.

AUMA service are comprehensively qualified to perform the specified interventions - a warrant for the explosion protection at all times.

Standard services

• Review of wiring for actuator and actuator controls
• Professional parameter setting
• Performance of tests and functional tests
• Maintenance and replacement of wear parts
• Implementation of required performance improvements

Optional services

• Enabling and setting of special parameters, e.g. positioner, process controller, optimisation parameters, interlocks 

Periodical inspections and sound overhauls are specified for safety-relevant actuators deployed in nuclear power plants. AUMA service experts are appropriately certified and have long standing experience with these interventions while respecting the specific safety regulations. They are furthermore qualified for inside containment interventions.

Standard services

• Professional parameter setting
• Performance of tests and functional tests
• Maintenance and replacement of wear parts
• Implementation of required performance improvements
• Complete and sound overhaul of actuators

Optional services

• Enabling and setting of special parameters, e.g. positioner, process controller, optimisation parameters, interlocks
