MEP-831 inverter troubleshooting

[Aby3250]

Greetings! I need help . My mep 831a turns on perfectly when turned on, it generates energy but after two or three seconds it gives the code.

Is the generator new to you?
Has it worked properly in the past?
I assume you mean the Overload/Short Circuit fault lamp illuminates and the contactor opens.

I bought it in those conditions. Yes, sometimes the low oil pressure light also comes on. When I get that error I can't turn it off using the power button.

If it doesn't shut off due to Low OP fault it's likely either the Governor Controller isn't working properly or the mechanical settings of the governor have been fiddled with.
The low OP fault may be due to a bad LOP switch. They fail with some frequency in the 831s. The OP is usually about 90 PSI when warmed up and the LOP shutdown switch trips at about 15 PSI.

What can you recommend I want to fix the problem. At first it turned off fine using the power button but then it didn't. But it always gave the overload short circuit code.

The -13&P TM has the adjustment procedure for both the SLC100 Goernor Controller module and the mechanical linkage on the governor.
The -13&P TM can be downloaded from the TM section of this forum.

Could you show me what it is since I totally don't know what you're talking about. Excuse me for my ignorance.

Here is a link to the Technical Manuals, TM's, for the 831A.
---> 831A TMs
See section 4-14 for the adjustment procedures.

I was able to download the manual but I can't find section 4-14.

See PDF page 159 of that -13&P

The version I referred to about 4-14 may be a different version. I have several version of the PDF.
