🔍 Key Concepts

• Protective engine trips vs. alarms and how quickly damage can occur • Difference between conditions that change gradually (like temperature) vs. suddenly (like overspeed or crankcase explosion risk) • Why some protections need instant reaction and others allow a short delay

💭 Think About

• Which unsafe condition can exist briefly without instantly damaging the engine, so that a short delay helps avoid nuisance trips? • Which conditions are so dangerous that you would want the engine to shut down or alarm immediately with no delay? • Think about start‑up and load changes: which parameter might momentarily go out of limits even though the engine is still operating normally?

✅ Before You Answer

• For each choice, decide if the hazard is immediate and catastrophic or develops over a short time • Identify which device commonly has a built‑in delay to avoid false trips during starting • Ask yourself: which of these parameters normally fluctuates and could briefly dip or rise past the setpoint without indicating true danger?
