7548/7794/7796/7796HC OPERATOR’S MANUAL – SECTION 7
Shut off the signal source before reset -
ting the amplifier. Try resetting the Fault
condition only once. If the Fault condi-
tion does not clear after one reset, STOP.
Contact AE Techron Support for further
assistance. Repeated resetting can dam-
age the amplifier.
CAUTION
7.7.4 Resetting After OverTemp
To reset the amplifier after an OverTemp has oc -
curred, make sure fans are running, then remove
the input signal from the amplifier. Allow the fans to
run for five minutes, and then push the Reset but
-
ton to reset the amplifier.
7.8 Fault LED is Illuminated
The 7548/7794/7796/7796HC contains protec -
tion circuitry that disables the amplifier if an output
stage is behaving abnormally. This usually indi
-
cates an output transistor has shorted.
To clear the Fault condition, follow these steps:
1. Turn off the signal source.
2. Turn off the AC mains.
3. Turn AC mains power back on. If the Fault LED
doesn’t illuminate again, turn the signal source
on.
4. If the Fault LED is still illuminated and the Fault
condition doesn’t clear, return the amplifier for
Factory Service. Please see the Factory Ser-
vice information at the end of this section.
