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 the temperature rises abnormally or there is an oil cooling defect, the sensor stops the compressor to protect the motor and screw assembly. Troubleshooting High-Temperature Issues
