Question 118Motor Plants - 1st Asst/Chief
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
AController setpoint changed
BThroughput too low
CEmergency stop button not reset
DSeparating temperature too low
AI Explanation
The correct answer is B) Throughput too low. A low-pressure in the oil outlet alarm indicates that the oil flow through the system is insufficient, likely due to a decrease in throughput or flow rate. If the throughput is too low, the pressure in the oil outlet will drop, triggering the low-pressure alarm. This is the condition that would be responsible for the alarm being indicated. The other options are incorrect because they do not directly relate to a low-pressure in the oil outlet. A change in the controller setpoint, an emergency stop button not being reset, or a separating temperature that is too low would not cause the specific low-pressure alarm described in the question.
