What is the initial step in troubleshooting a control system?

The initial step in troubleshooting a control system involves verifying that something is indeed wrong. This is crucial because troubleshooting requires an accurate understanding of the system's current state. By confirming that an issue exists, the technician can avoid unnecessary adjustments or repairs to components that may be functioning correctly.

After this confirmation, the technician can proceed to identify and locate the precise problem, but without the initial verification of an issue, any further troubleshooting steps may be based on assumptions rather than fact. This foundational step sets the stage for an effective troubleshooting process, enabling the technician to make informed decisions moving forward. Thus, ensuring that a problem exists before taking action is essential in the protocol of addressing control system issues.
