The ES3000 monitors air/oil temperature through an NTC100K sensor. A high-temperature signal (typically triggered when the internal temperature exceeds roughly ) will cause a red LED to light up and the machine to stop immediately.
If your compressor is shutting down due to heat, check these common causes and solutions: es3000 compressor controller manual pdf hot
Ensure the cooling fan is rotating in the correct direction and moving air across the heat exchangers. The ES3000 monitors air/oil temperature through an NTC100K
Once you have identified and fixed the root cause of the heat issue, you must manually reset the controller before the compressor can be restarted. Once you have identified and fixed the root
Check the oil level through the sight glass while the machine is running (if possible) or after a short rest. Low fluid levels cause rapid overheating.
A clogged oil filter can restrict flow, leading to "fluid starvation". A hot oil filter usually indicates oil is moving, while a cold one might suggest a blockage.
