Operator Fault

¿Qué significa 11 ?

This fault occurs specifically when the program keypad module is physically removed from the controller while the controller is still powered on. It is a protective measure to prevent unintended parameter changes or operational interruptions.

• Keypad module was physically disconnected or vibrated loose from the controller's front panel while the controller was still energized.
• Damaged or dirty contact pins on the keypad module or the controller's keypad interface port.
• Accidental removal of the keypad by personnel during operation or troubleshooting.
• Loose mounting screws or clips allowing the keypad to detach inadvertently.
