: Starts the shutdown phase; the compressor will run in "no load" before stopping .

To adjust the pressure setpoints (load/unload), the compressor must usually be stopped .

: The PT100 probe or thermistor can degrade over time, transmitting a false high reading to the controller analog inputs. Viewing and Programming Heat Parameters

Digital display of the current line pressure. Temperature: Internal temperature of the air/oil mixture. Hours: Total running hours and loaded hours. Troubleshooting with the ES3000 Controller

Always prioritize safety. The information in this guide is for reference. Only qualified personnel should perform electrical work on industrial equipment. Always disconnect and lock out all power sources before opening electrical enclosures. If you are ever in doubt, consult with a certified compressor technician.

Insufficient lubrication increases internal friction, rapidly raising the operating temperature.

If fluid levels and ventilation are optimal, the internal cooling loop components may be failing.

This comprehensive technical guide explains how to use the to troubleshoot hot running conditions. It covers reading thermal sensors, adjusting software safety thresholds, and fixing underlying mechanical faults. ES3000 Temperature Monitoring Architecture

The controller abruptly stops the compressor to prevent fire or mechanical seizure. A specific error icon or code (often indicating a thermal fault) illuminates. Typical threshold: 110°C (230°F).

: Overloaded thermal relays or electrical phase imbalances will trigger a motor overload fault, bleeding excess thermal energy into the machine chassis.

The controller triggers an automatic safety shutdown. The compressor stops immediately to prevent oil degradation and mechanical seizure. The display will show a specific fault code, often accompanied by a blinking red error light.

: Check connector CN5 (terminals 33–35) for loose or damaged wiring to the NTC100K temperature sensors.
