← TechnologyWhich risk increases when a hydraulic actuator's position feedback signal is lost?
A)Uncontrolled motion and potential damage✓
B)Reduced pump efficiency and overheating
C)Increased fluid contamination and leakage
D)Premature wear due to higher pressures
💡 Explanation
When position feedback is lost, a closed-loop control system fails because the controller cannot correct deviations from setpoint, leading to actuator runaway. Therefore uncontrolled motion results, rather than pump inefficiency, fluid contamination or premature wear, which require different mechanisms.
