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 5.5 Menu
FAULTS LOG).
The data can be downloaded from ACOM 1200S 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:
• 8 to 15 V DC voltage applied to the "DEBUG mode" input (see Table 2-1 Signals and pin out of
the CAT/AUX connector) of the CAT/AUX port. The power supply has to be capable to provide
0.4 A of current;
• If the Control board has already been taken out of 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 Section 5.5 Menu FAULTS LOG), the Control board automatically
transmits the data from the memory trough the RS-232 interface (see Section 2.5.b) RS-232 interface
connector). Depending on the number of fault events stored 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 ACOM Hard Faults Signatures Converter
(Excel file), distributed by ACOM free of charge. You can download it from www.acom-bg.com.
