🔍 Key Concepts

• Location of the water content sensor in the diagram (look at the MARST1 connections and where they tie into the oil outlet line). • What an abnormal water content alarm means for the quality of the cleaned fuel oil leaving the purifier, not for the operating water system. • How a mechanical leak or separation failure at the bowl/paring disc interface would affect water in the fuel outlet compared to general fouling or tank level issues.

💭 Think About

• Follow the piping from the separator bowl to the oil outlet and note where the control unit is monitoring for water – what exactly is it measuring? • Ask yourself which option would most directly introduce water into the clean oil outlet path, rather than just making the machine dirty or a tank full. • Consider whether a simple high water content in incoming fuel would be called an equipment alarm, or more a fuel quality issue – what condition inside the separator would actually cause that high reading at the sensor?

✅ Before You Answer

• Verify which parts of the system are monitored by MARST1 versus the EPC unit – focus on the MARST1 A01 description box. • Check whether any instrument or sensor is shown on the operating water tank; would overflowing that tank change the reading at the water content sensor? • Look closely at the bowl and paring disc area in the illustration and think about what happens if sealing between them is lost – where would the separated water go, and what would the sensor see?
