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.
