What should be included in the PLC output diagram related to motor starters?

The PLC output diagram for motor starters should include the normally closed (NC) contacts of the motor starter, as these are crucial for understanding the operational logic of the system. Including NC contacts allows for insights into safety interlocks and control logic. These contacts are often used in conjunction with the programmable logic controller to ensure that the motor cannot be inadvertently started when it is unsafe to do so, such as when a safety guard is not properly in place.

By including this information in the diagram, the designer can depict the circuit’s behavior when the motor is not in operation, thereby illustrating how the system will function under various conditions. Understanding the role of NC contacts aids in troubleshooting and validating system performance in various scenarios.

The other options, while important in their own contexts, do not directly affect the PLC output implementation for controlling motor starters in the way the NC contacts do. The manual override controls provide a way to manually operate the motor, but do not depict the interlock safety features associated with start/stop processes. Power supply details give information about the source of power but do not inform the PLC's output logic. Input sensor connections are relevant to how the motor is triggered but are not directly part of the output diagram itself.
