Learn More About ProofCheck™

Automated, Repeatable, Reliable Execution

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.

Intelligent Field Device Loop Testing

Validation and periodic Proof Testing requires sending signals from the field instruments. This process verifies not only the instrument, but also wiring, junction boxes, and signal conditioning between device and the SIS. Sending technicians to the field with handheld communicators to manually set devices in loop test mode is time intensive, error-prone, and may expose the field technician to a variety of hazards including heights, temperature extremes, and chemicals.

ProofCheck allows the technician to set the output of transmitters from a workstation or tablet. This non-intrusive testing automatically returns devices to their proper state after testing. ProofCheck allows for automated testing of your plant’s SIS voting logic.

Capture Manual/Visual Verification

Many testing steps and activities performed for safe return to operations, require manual interaction. ProofCheck captures these manual/visual verifications and validates technician responses in the same manner as automated verifications.

Manual verifications can capture items like:

Did the valve stem move?
Did the light/siren activate?
Instruct an operator to press the reset button after a trip
Set/reset a breaker
Any manual action
Operators can add notes/pictures to the record

Safe Return to Operation

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.

BPCS Test Procedures

In addition to thoroughly testing SIS, ProofCheck can verify Basic Process Control Systems (BPCS), commonly known as Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), and other automations systems at the site.

ProofCheck is a perfect fit for testing these other systems along with their connected field devices.

The test procedure can set/reset any variable, set a recipe variable, enable/disable alarms or any other required value for testing/return to operations. Automated BPCS trip resets or alarm acknowledgements can also be set by ProofCheck allowing comprehensive testing for all systems at the site.
