ProofCheck™

ProofCheck™ delivers a comprehensive out-of-the-box testing solution for Safety Instrumented Systems (SIS). ProofCheck incorporates all elements of proper SIS Validation and Proof Testing in a single solution. Validate sensors, wiring, signal conditioners, safety logic, final control element response, as well as manual inspections.

The customizable procedures drive efficient, repeatable, reliable testing processes, and ensure equipment is properly set for safe return to operations.

Procedure execution data is captured electronically and validated against predefined limits. ProofCheck shows pictures, manuals, loop sheets, and any information required by a technician to perform the tests. The built-in reports and monitoring screens show test progress, highlight errors, as well provide the documentation required for permanent record.

As the procedure is executed, ProofCheck records HART field devices response, OPC variable values, manual inputs, while automatically verifying that the test criteria are met. For systems such as Emerson’s DeltaV™ SIS, ProofCheck can even verify that the safety logic has not changed by verifying the SIS System CRC codes.

IEC 61511 provides guidelines for safety testing, and safe return to operations. This includes testing all the SIF functions including redundancies, bypass, reset, and other potential safety states. Proper testing requires checking these SIS and device functions. In addition, after testing ensuring the SIS system, and field devices are back to the normal operation settings, alarms are enabled, and test materials and tools were removed. The comprehensive validation provided by ProofCheck out-of-the-box makes it easier to ensure compliance.

Our built-in reports provide all the information needed for compliance, auditing, and quickly determining what needs to be fixed. Reports expedite safe and efficient return to operations and eliminate countless hours of paperwork processing.

Spend time improving your plant’s safety, and optimizing your process, instead of filling out forms.
