4.3.1 Front Panel LEDs
Three LEDs are located on the front panel: one green, one yellow, and one red. These LEDs are used to display the
alarm status of the power system, controller progress and status during startup, and file transfers.
Alarm conditions
Only one LED light is illuminated at a time during alarm conditions. Each LED light corresponds to a specific alarm. A
built-in audio speaker sounds an intermittent tone during active alarms. An LCD message display provides details of
all major and minor alarms.
