1550 oil free sullair compressor, engine and compressor not communicating!


When you press start the unit only carry out checks and shuts down, error comes up communication or data link error.

It seems like the compressor is shutting down the engine before it starts.

That's right.

Probably a broken or loose cable between the two. It's on-board diagnostics, and yes, they have to communicate to co-ordinate engine speed (for E.G.) and compressor demand.

So look for a relatively small cable running between the engine controller and your control panel. If you're lucky, it just broken or has a loose connector somewhere.

Good luck.
