2.3 Cordex System Controller
A Cordex system controller (CXCP), mounted in one of the BDFBs, provides easy access to controls and display
status. The CXCP provides comprehensive setup, control, monitoring and communication for Alpha DC power
systems.
The CXCP features include the following:
• Local and remote communications
• User definable alarms
• Daily logging of events and system statistics
See the CXC Software Manual shipped with your order for detailed information.

Progress and status indication
The LED lights are also used in the following situations:
• Base unit validation—all three LEDs illuminate
• File transfer—red LED illuminates
2.3.1 Front Panel Reset Button
If it is necessary to reset the controller (before a power-down for example), use the LCD to select the reset menu
item. Resetting from the LCD initiates a soft reset with no loss of data.
The reset button (Figure 6) on the front panel initiates a hard reset of the CXC microprocessor. No data is saved
and should be used only If the controller is hung up. It takes approximately 15 seconds before the display reap-
pears after pressing the reset button.

2.3.2 Front Panel LEDs
Three LEDs are located on the front panel: one green, one yellow, and one red. These LEDs display the alarm
status of the system, controller progress and status during startup, as well as 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.
