E2000 with an unplugged Mystery Coil? Anyone know it's funtion?

[danatlvc]

I have a E2000 double progressive.  There's a coil that's unplugged in the right corner & I don't know what it goes to. I don't want to plug it in until I know it's function to be safe learning from past mistakes. The machine works excellent with the exception that the progressive doesn't progress. I can set the progressive up thanks to the help on this site, but that's it. Anybody know what this coils function is? Thanks

the coil is the door open buzzer - goes off every 45 seconds when door is open - annoying - hence disconnected.
