2.3 FAULT REPORTING AND FAULT CODES
SYSTEM FAULT CODES provide one of the most important ways to quickly locate and assess problems
in the MicroGuard®System. Please review this section carefully.
Each time the system is turned on, it goes through a self-testing process lasting six seconds that
automatically detects most faults in the system. During normal operation, a self-test can be initiated
at any time by pressing the TEST button on the display console.
Many fault conditions are detected without a system self-test.
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 of the text window.
Fault codes may be displayed on the display console. To view the codes, press and hold the TEST
button and wait for the system to complete the self-test. Do not release the TEST button. Fault codes
will now be displayed at the bottom of the text window for as long as the TEST button is held down.
