How do you clear an ERROR message?

• A. Press CANCEL
• B. Press RESET softkey
• C. Power cycle the controller
• D. Navigate to the Maintenance page

Answer: (A)

Acknowledging the fault on the operator panel is how you clear an ERROR message. Pressing CANCEL is the standard action to dismiss the error dialog and return you to the previous screen after you’ve acknowledged the issue. This clears the on-screen message without changing the controller’s state, letting you proceed if the fault doesn’t require a reset. A RESET softkey would perform a fault reset or reinitialization, which is more disruptive and isn’t needed just to clear the message. Power cycling is a drastic step used only when the controller is unresponsive or the fault can’t be cleared by software. Navigating to the Maintenance page isn’t necessary for clearing a single error; that page is for diagnostics and configuration.
