FAN2 Fault
Processor Fault
Note: A temperature fault is indicated if
the unit is
≤
-12
°
C or
≥
+80
°
C. This
creates a summary fault and will cause
the unit to mute itself and switchover to
the back-up unit. However, the 9V
supply to the FET transistors will
remain on until the unit reaches the
thermal shutdown temperature of
≥
89
°
C. For protection reasons, the unit
will shutdown the 9V supply to the
power transistors at temperatures
≥
+89
°
C.
