Note: A temperature fault is indicated if the unit is less than -
20C or more than 85 degrees C. This creates a summary fault and
will cause the unit to mute itself and switchover to the back-up
unit. However, the 10V supply to the FET transistors will remain
on until the unit reaches the thermal shutdown temperature of 90
degrees C or above. For protection reasons, the unit will
shutdown the 10V supply to the power transistors at temperatures
at or above 90 degrees C.
