Which statement accurately describes the sequence involving PB1?

The correct answer describes a sequential operation that emphasizes the timing and control of different motors based on the input from PB1. When PB1 is pressed, it initiates a series of actions within the system.

In this scenario, pressing PB1 triggers the Lube Pump Motor to activate. The Impeller Motor is also turned on simultaneously. This reflects a typical operation in programmable controller systems, where a single input can control multiple outputs effectively. The operation includes a specified time for each motor to run, allowing for controlled processes that can prevent potential issues such as overheating or excessive wear on the motors.

After the specified time for each motor has elapsed, both motors are then turned off. This sequence ensures that the system operates safely and efficiently, consistent with good practices in programming and automation control. Timing is a critical aspect in these types of operations, allowing for effective coordination between motors for tasks such as lubrication or fluid movement, ensuring that components of the system are adequately prepared for their respective functions.

This choice accurately captures the functionality and operational logic expected from programmable controllers in industrial systems, where precise timings and coordinated actions are crucial for optimal performance.
