🔍 Key Concepts

• Trace the oil outlet line in the MO-0127 diagram and note every component that could reduce pressure (valves, sensors, switches). • Consider how a vibration switch, a water solenoid valve, and high throughput each might change flow or cause a shutdown/bypass in this system. • Think about the relationship between flow rate and pressure in a piping system (too much flow vs. blocked/closed paths).

💭 Think About

• For each option (A, B, C), ask: would this condition realistically cause the pressure at the oil outlet transducer to drop below its alarm setpoint, or just stop the system entirely? • Does the vibration switch act directly on the oil line pressure, or does it trigger a protective function elsewhere that could indirectly affect outlet pressure? • What does a faulty water solenoid valve actually control in this separator system, and would its failure lead to loss of oil outlet pressure?

✅ Before You Answer

• Verify in the illustration where the pressure transducer/sensor for the oil outlet is located and what it is connected to. • Check which alarms and switches are tied to emergency stopping or vibrations versus product outlet conditions (oil outlet, water outlet). • Confirm whether excessive throughput in a separator tends to raise backpressure, lower outlet pressure, or cause other types of alarms (e.g., no discharge, abnormal water content).
