What designation indicates that the system is operating incorrectly in troubleshooting charts?

• A. Symptom
• B. Alarm
• C. Fault
• D. Condition

Answer: (A)

In troubleshooting charts, the term used for an observable sign that something is not operating correctly is a symptom. It describes what you can see or measure that indicates a problem, without claiming the exact cause. Recognizing the symptom is the first step that guides you toward diagnosing the underlying fault. For example, a lack of output, unusual vibration, or drop in pressure are all symptoms that alert you something is wrong and need investigation. An alarm is a specific alert signal tied to a threshold or safety limit; it indicates abnormal operation but is a particular type of warning rather than the general designation for a malfunction you’re diagnosing. A fault refers to the actual failure or malfunction in a component or system, which is the root cause you aim to identify after noting the symptom. A condition is simply a state the system can be in and may be normal or abnormal, but it doesn’t by itself convey that the system is malfunctioning in the investigative sense used in charts.
