🔍 Key Concepts

• Role of a vibration (emergency stop) switch on a fuel oil separator • How the separator bowl should be handled during a vibration trip and rundown • Purpose of keeping the bowl filled with liquid vs. empty when stopping

💭 Think About

• From the illustration, what does a vibration alarm/emergency stop protect against in a high‑speed rotating bowl? • During rundown after a vibration trip, would a full or empty bowl better prevent damage from imbalance and friction? Why? • Which option focuses on correcting the cause of vibration rather than changing alarm setpoints or ignoring the device?

✅ Before You Answer

• Make sure the procedure includes stopping the separator when excessive vibration occurs. • Confirm that the step includes investigating and rectifying the cause of vibration before restarting. • Check whether the option tries to defeat or override the safety device (like lowering the vibration switch setpoint) – such an option should be avoided.
