What should you do when a warning alarm sounds during operation?

• A. Stop the machine, investigate the alarm code per the manual, and address any fault before continuing.
• B. Silence the alarm and keep operating until the next scheduled stop.
• C. Ignore the alarm and proceed as if nothing is wrong.
• D. Reset the control system without checking the code.

Answer: (A)

When a warning alarm sounds, treat it as a signal that something in the system may not be operating correctly and could affect safety or performance. The correct action is to stop the machine, look up the alarm code in the manual to identify the fault, and address the issue before continuing. This ensures you don’t overlook a problem that could worsen, cause damage, or put you at risk.

Silencing the alarm and keeping the machine running, ignoring the alarm, or resetting the control system without checking the code all bypass safeguards and prevent you from understanding and fixing the underlying fault. Following the manual’s guidance for diagnosing and correcting the fault, and verifying the condition is resolved before resuming, is the responsible and safe approach.
