Module 15 · Lesson 2

FAT, SAT and commissioning documentation

Plan and execute factory acceptance, site acceptance, loop checks and performance tests.

Learning outcomes

Explain the key principles of fat, sat and commissioning documentation.
Carry out a structured practical check or configuration task.
Recognise common faults, risks and evidence needed for diagnosis.

Before you begin

Approved test procedures and issue register.

Safety: Use site procedures, approved test equipment and competent supervision. Never bypass a protection or interlock without formal control.

Step-by-step learning

Trace every requirement to a test step and expected result.
Record pass/fail, evidence, tester and issue reference.
Control simulation, forcing and temporary wiring.
Close defects or formally accept outstanding limitations before handover.

Ian's practical tips:

A signed checklist is not proof unless the result and evidence are meaningful.
Test failure behaviour as thoroughly as normal operation.

Fault-finding questions

What should be happening, and what evidence proves it?
Where is the last known correct signal, voltage, state or process condition?
What changed immediately before the fault?
Can the system be divided into smaller testable sections?

Practical activity

Create a one-page test record for this lesson. Include expected values, measured results, equipment used, risks controlled, defects found and the final proven condition.

I completed the lesson activity. I checked the result safely. I can explain the fault-finding approach.
