Hello Hawk,
To clear a Fault 99 on an Alpha 87A amplifier with a PC connected to serial
port:
Amp plugged into AC but not turned on.
Type in the following commands and enter them for each new line. You can
also
copy and paste the entire string of commands (include EXT ON at beginning
thru
SF at end) into the Hyperterminal window, put cursor at END of the list and
hit
enter. They will be sent in sequence to the 87A.
EXT ON
W B71A FF
W B71B FF
W B71C FF
W B71D FF
W B71E FF
W B71F FF
W B720 FF
W B721 FF
W B724 FF
W B725 FF
W B726 FF
W B727 FF
W B728 FF
W B729 FF
W B72A FF
W B72B FF
W B72C 0C
W B72D B5
W B7E0 FF
W B7E1 FF
W B7E2 FF
W B7E3 FF
W B7E4 FF
W B7E5 FF
W B7E6 FF
W B7E7 FF
HF
SF
When you type HF and SF they should show all 00.
Unplug the 87A from the mains power for 30 seconds. This resets the
microprocessor.
Once you have cleared the Fault 99, turn on the amp and the original fault
may show up.
