Using The Fault Codes (Signatures) For Diagnostics - Acom 700S User Manual

Besides the primary fuses, there are internal fuses inside the amplifier.
Do not replace internal fuses located inside the amplifier.
Blown internal fuses can be a symptom of a more serious problem, which should be
resolved beforehand. A fault of this type will not occur under normal operating
circumstances.
Replacing internal fuses is a complex and potentially dangerous operation.
For this reason, we recommend this work be carried out only by a trained service
technician.
Contact your ACOM dealer for assistance (see Section
Unauthorized replacement of inside fuses infringes the warranty conditions!
Besides several specific national standards, the principal fuses standard
worldwide is IEC 60127.

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:
8 to 15 VDC voltage applied to the "Debug mode" input (see

transmits the data from the memory trough the RS-232 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, thеn 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.
