Controller Status LED: This LED is the primary back panel indicator of alarms. An

alarm is generated when a specific condition is identified and is cleared when the

specified condition is no longer detected. When an alarm is posted,

1) The controller status LED turns orange for 5 seconds

2) The controller status LED turns off for 5 seconds

3) The controller status LED flashes orange the number of times specified by the first

digit of the alarm code

4) The controller status LED turns off for 3 seconds

5) The controller status LED flashes orange the number of times specified by the second

digit of the alarm code

Steps 2-5 are repeated for each alarm posted. The entire process is repeated as long as

the alarms are still posted.

For all modules, a green LED indicates normal operation and a red LED indicates mdule

fault. Alarms are also shown in the Web Interface, Command Line Interface (CLI), and .
