At one time I thought I had seen a list of error codes posted.  I can't find them now.  any help would be appreciated.

My 22KW NG threw a 2800 code last night and I'm not sure what caused it.  I was able to reset.

2800 is "External shutdown circuit open"  Check the e-stop buttons and wiring harness.

That unit will have two switches. One switch exterior rear corner area where the gas and electric connect to generator. Second on the interior right side engine compartment fire wall adjacent to the controller area. If either or both are off it will throw that 2800 code.

Thank you for the reminder about the common codes. I will try to find it soon and post it prominently. If anyone else has seen it post it and I will lock it in place.

Checking the switches was the first thing I did.  Neither switch was set to the "off" position.  I did reset the switches by turning them off and then back on.  From what I understand, they are just normally "on" switches so don't know what my reset accomplished.

Anyway, after resetting, I cleared the code on the panel, and all was fine.

By the way, what are these switches called?

All Evolution error codes flash the name as well as the code number alternately, and I believe even in the HISTORY>ALARM LOG the names in addition to the numbers are shown as well.

So there is no need to refer to a list of all codes or a book to translate a 2800 into "AUX SHUTDOWN".  

They are called E-Stop switches, and are there so the unit can be shut down without opening the top.

The fault will be set and require acknowledgment even if you only momentarily turn either of the switches off, even if the unit was not running at the time.
State your problem, not your diagnosis.

They are auxiliary shut down switches. Possibly one of the switches may have been set to off, then back on.. Or accidentally bumped.. The error code wouldn't have cleared until you did so manually.

I did find that list. Unfortunately it didn't export/import properly. I don't know how to fix it.
