Reading Auto-Protection Signatures - Acom 1000 User Manual

5.3. Reading Auto-protection Signatures

On every Hard Fault protection trip of the amplifier, signature information is stored in its nonvolatile
memory. The 7 most recent auto-protection trip signatures related to the amplifier internal status are
stored there, which you can copy and forward to your dealer for diagnostics.
In order to read them press the OPER button while OFF LINE. You'll see the beginning of the signatures list.
Use NEXT and PREV buttons to navigate through 7 pairs of screens. For each auto-protection trip there is a
pair of information screens, beginning with nA... and nB... where:
"n" is the number of the event (nr.1 is the latest, nr.7 is the oldest one);
•
A and B mark the first and the second part of an information screen pair.
•
Two lines, three groups by six symbols (36 symbols in total) are to be copied concerning every one of the 7
memorized events from 1A-1B through 7A-7B.
To decode the signatures see Section
Забележка!
Note!
After every signature listing the tube warm-up time is reset to 150 seconds regardless of
the time being in OFF LINE state.
