7.4. Using the Fault Codes (signatures) for Diagnostics

The data of the last 28 HARD FAULT protection trips is stored in the amplifier memory (see Section
).
FAULTS LOG
The data can be downloaded from the memory through the RS-232 port and stored in a computer file even
if the amplifier cannot be turned on after a serious fault - only external power has to be fed to the Control
unit in either of the following ways:
External 8 to 15 VDC voltage applied to the "DEBUG mode" input (see

pin out of the CAT/AUX connector
provide 0.4 A of current;
If the Control board has already been removed from the amplifier, it can be powered directly
•
with +5 V (0.4 A) and the fault log downloaded via the RS-232 port.
In the FAULT LOG reading mode (see
transmits the data from the memory trough the RS-232 interface (see Section
). The RS-232 protocol settings are: 9600, 8 N 1. Depending on the number of fault events stored
connector
in the memory, the transmission may take between 0.5 and 12 seconds. A pause of 6 seconds follows, then
transmission starts again. The data can be read in a plain-text format with a computer, using a standard
terminal emulating program (TTY).
You can send the recorded file to your dealer or to ACOM accordingly.
To decode the downloaded hexadecimal data, you have to use the
