Gross Schaltschrankbau tests control cabinets and assemblies against the agreed test scope and documents the results traceably. Visual, build, wiring, electrical and functional tests provide certainty before approval, shipment and commissioning.
Inspection
Visual, build and wiring inspection
Measurement
Electrical measurements according to the test plan
Function
Functional testing to the agreed extent
Verification
Test report and approval status
Test scope
Three test types and three levels of testing. The combination that applies is defined before production starts – a test scope cannot be verified retrospectively.
Visual and build inspection
Check components, labelling, cable routing, degree of protection, fastening and conformity with the drawings.
Electrical testing
Depending on the test plan, carry out protective conductor continuity, continuity, insulation, dielectric strength and other measurements.
Functional test
Test switching sequences, operation, messages, inputs and outputs, safety and communication functions.
In-process inspection
Check critical characteristics during assembly and wiring.
Routine and final testing
Test and record every unit against defined criteria before approval.
Factory acceptance test / FAT
Joint acceptance, simulation and documented approval.
Process
Testing is not a step at the end, but a chain of checks along the production process. Anything that only shows up in the final test has to be corrected in the fully wired cabinet – where every deviation costs many times more.
The basis is a test specification defined before work starts: which characteristics are tested, against which status, with which equipment and with which documentation? Without this definition, a test result is not reliable.
We test against the approved drawing and build status, not against an expectation. Deviations are documented and reported back instead of being decided in the workshop.
The result is a traceable approval with the agreed evidence – the basis for handover, commissioning and any later queries.
01
Agree test scope, limit values and responsibilities.
02
Verify revision, BOM and target values.
03
Check build, marking and workmanship.
04
Carry out electrical measurements and functional tests.
05
Document results and record the approval status.
Test basis
Documentation
A test report is only reliable when test scope, measured values, evaluation and responsibility are clearly assigned.
Test report
Test scope, measured values, evaluation, tester identification, product assignment and approval status.
Deviations
Document, correct, retest and approve findings.
