2.14 Light Beacon
The Light Beacon is a device that displays system status and can warn the operator when fault conditions
exist. The beacon has red, yellow, green, and blue lights that can be solid or flashing. The beacon also has
an audible alarm. Table 2-3 provides possible reasons for each color indication.
Software and hardware share control of the beacon lights. Sometimes, hardware-driven displays override
those caused by software conditions and sometimes software-driven displays override those caused
hardware conditions. Safety critical conditions always have priority. Flashing light software commands
have priority over solid light commands.
NOTE Light beacon action can be custom configured using the beacon control feature. Refer
to the Easy Coat User Guide for details.
Refer to Section 8 - Troubleshooting for suggested recovery from common fault
conditions.
