Faults detected in the system during the self-test, are indicated on the display console in the following
ways:
The RED OVERLOAD LAMP will illuminate. The AUDIBLE ALARM will sound.
“WARNING SYSTEM FAULT!” will be displayed at the bottom o f the text window.
Fault codes may be displayed on the display console. To view the codes, press the TEST button and
wait for the system to complete the self-test.

listing of each code is provided on the following pages.
