System/SES Fault LED & Audible Alert

fault includes over temperature, power fault, or blower fault. The buzzer will
sound off with a sequence of beeps to indicate the fault that has occurred.
2 beeps = Temperature Fault

5 beeps = Power Supply Fault
The light will stay on red if a fault occurs. During normal operation, the red light
will blink to notify that internal SES monitoring is working.
