What indicates the operational status of the FANUC system visually?

The operational status of the FANUC system can be indicated visually through both the Fault LED and the Power LED. The Fault LED provides clear visual feedback about any errors or malfunctions in the system. When this LED is lit, it signals that there's a fault that requires attention, allowing operators to quickly assess whether the machine is operational or if it needs troubleshooting.

On the other hand, the Power LED indicates whether the system is powered on and functioning. A lit Power LED confirms that the power supply is operational, ensuring that the system is ready for use. Together, these two indicators provide essential information about the system's state, allowing operators to determine not only if the system is on but also if it is functioning correctly. This dual visual feedback is critical for effective monitoring and management of the equipment.

Other options may refer to components that contribute to status awareness, but they do not provide the dual visual indication that the Fault and Power LEDs offer collectively. Thus, both LEDs together serve as crucial indicators of the operational status of the FANUC system.
