70% to passAs shown in the illustration, which of the following conditions would be responsible for a "low-pressure in oil outlet" alarm to be indicated? Illustration MO-0127
AThroughput too low
BSeparating temperature too low
CController setpoint changed
DEmergency stop button not reset
AI Explanation
The correct answer is A) Throughput too low. A low-pressure alarm in the oil outlet would indicate that the oil flow or throughput is too low. This could be caused by a blockage or restriction in the oil line, a malfunctioning pump, or other issues that reduce the oil flow. Separating temperature, controller setpoint, and the emergency stop button are not directly related to causing a low-pressure alarm in the oil outlet. The other answer choices are incorrect because they do not directly impact the oil outlet pressure. A low separating temperature, changed controller setpoint, or an un-reset emergency stop button would not independently trigger a low-pressure alarm in the oil outlet.
