Referring to the illustration, what would be the result if the lower oil/water interface detection probe became faulty? GS-0175

Correct Answer: Option C — The unit would not be able to transition from ending the separation processing mode to initiating the oil discharge mode.

The lower probe monitors the oil-water interface to determine when the separation process is complete and the unit is ready to discharge accumulated oil. If this probe fails, the logic controller cannot verify the oil level, preventing the transition from the processing mode to the oil discharge sequence.
