[Kiln error -PLOG Orton AutoFire 2000]

Hi everyone, thank you for your feedback! I contacted orton and they sent me this response. So it sounds like I'll just need to wait and see what happens in future firings to see what's going on. Thanks for your input!

[Kiln error -PLOG Orton AutoFire 2000]

Hi all,

This is my first post and I'm in need of some help. I have an electric kiln run on an AutoFire 2000 Kiln Controller by Orton. This was my first bisque fire. I'd done one test fire previously with no issue. 

Today, I set my bisque for cone 04, 2 hr preheat, slow (as I have some thicker pieces). It was nearing 11pm and had reached 1600-something degrees, so I set my alarm for 1am to check on the kiln. I found my controller flashing "PLOG 134". My manual says PLOG is a diagnostic error that can usually be corrected with the enter key. 

I pressed enter and the kiln resumed firing, although upon reviewing the program, it was not set to today's schedule. I aborted the firing and reset to my schedule of cone 4.

I have no idea what happened or what this error means. Any ideas why my kiln had a diagnostic error? 

THANK YOU!
