Question 378Electricity & Electronics - Assistant Engineer

The correct answer is A) Run indicator lamp is ON, Overload indicator lamp is ON. In a steering system hydraulic power unit motor controller, the run indicator lamp being ON and the overload indicator lamp being ON indicates that the motor has encountered an overload condition. This is the expected response, as the overload indicator lamp will illuminate to signal that the motor has exceeded its safe operating limits, while the run indicator lamp remains ON to show that the motor is still running. The other answer choices are incorrect because they do not accurately reflect the expected response to a motor overload condition, as outlined in the illustration EL-0119.
