FAN FAULT
1
Illuminated indicates the exhaust fan has stopped rotating.
The POWER ON LED remains illuminated, and the amplifier is
fully functional until a TEMPERATURE FAULT occurs.
TEMPERATURE FAULT
1
When illuminated, indicates the internal heat sink
temperature exceeds 75 °C.
All amplifier functions are disabled, the POWER ON indicator
extinguishes, and any other fault indicators are disabled. The
amplifier remains non-functional with the TEMPERATURE
FAULT indicator illuminated until the heat sink temperature
drops to less than 50 °C, at which point, the amplifier will
automatically restart.
MODULE FAULT
1
When illuminated, the MODULE FAULT LED indicates that
one or more amplification modules in the final stage of the
power amplifier are malfunctioning. The POWER ON indica-
tor remains illuminated, and the amplifier remains functional
at reduced capability and performance.
