Using the fault codes (signatures) for diagnostics

The data of the last 28 HARD FAULT protection trips is stored in the amplifier memory – see S. 4-6(c).
The data can be downloaded from the memory through the RS232 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 15V DC voltage applied to the "Debug mode" input (Table 2-1) of the CAT/AUX port. The
power supply has to be capable to provide 0.4A of current;
- if the Control board has already been removed from the amplifier, it can be powered directly with
+5V (0.4A) and the fault log downloaded via the RS232 port.
In the FAULT LOG reading mode (Fig. 5-5), the Control board automatically transmits the data from the
memory trough the RS232 interface. 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, than transmission
starts again. The data can be read in a plain-text format with a computer, using a standard terminal
program.You can send the recorded file to your dealer or to ACOM accordingly. They could also
provide the necessary instructions, if you choose to decode the downloaded hexadecimal data by
yourself.

FIRMWARE UPDATES

When ACOM issues a new firmware version, the user can upload it in the amplifier after he checks the
compatibility – see the note above.
When compatibility is confirmed a return to an earlier version is also possible.

Before you change the firmware version, check the new version
compatibility with the revisions of the hardware and of the boot
loader in your amplifier - see S. 5-5. If you have any doubts about
the versions, please consult your dealer before you undertake
any action.
