Within hydraulic elevators employing a PID controller, which outcome occurs when inadequate filter maintenance introduces particulate contamination?

💡 Explanation

Spool seizure increases because particulate contamination causes restricted movement; the PID controller attempts compensation via increased valve activity, accelerating wear due to abrasive contaminants. Therefore, valve seizure probability rises, rather than improved pump efficiency or lowered viscosity due to contamination.
