When the ES3000 compressor controller detects a "hot" condition (high temperature), it follows a two-stage safety protocol to protect the machine from damage. 1. Temperature Alarm Thresholds
According to the ES3000 Instruction Book, the system monitors the temperature through the NTC100K probe (terminals 33–34).
Pre-Alarm (Flashing LED D): Typically triggered when the temperature reaches 100∘C100 raised to the composed with power C ( 212∘F212 raised to the composed with power F ) or within 5∘C5 raised to the composed with power C
of the shutdown limit. The compressor will keep running, but the alarm flashes to warn of impending shutdown. Shutdown Alarm (Solid LED D): Triggered at 105∘C105 raised to the composed with power C ( 221∘F221 raised to the composed with power F
). The controller will immediately stop the compressor to prevent internal oil or component damage. 2. Common Causes & Solutions
If your controller shows a high-temperature fault, check these specific areas identified in the ES3000 Troubleshooting Guide: Potential Cause Dirty Oil Cooler
Blow out the cooler with compressed air or use a cleaning solution. Low Oil Level Top off the oil tank to the proper level. Fan Motor Failure
Verify the fan is spinning; check for a tripped fan motor thermal relay (LED E). High Ambient Temp
Ensure the compressor room has adequate ventilation; temperature should be below . Faulty Sensor
Inspect wiring on CN5 (terminals 33-34) for damage or loose connections. Clogged Air Filter
Check LED L; a restricted intake can cause the unit to work harder and run hotter. 3. How to Reset the Alarm
Allow the compressor to cool down below the pre-alarm threshold (usually below 95∘C95 raised to the composed with power C ).
Press the Reset button on the front panel to clear the red alarm LED.
If the error persists immediately upon startup, check for a "General Alarm" (LED G) which may indicate a faulty temperature probe.

on a Chicago Pneumatic or Atlas Copco air compressor uses a "hot" or high-temperature alarm to protect the unit from permanent damage. When this happens, the controller will typically display a red pilot light and may shut down the machine. Common Causes for High Temperature
According to troubleshooting guides from John Bouchard & Sons Co. and the ES3000 Operation Manual, "hot" errors are usually caused by:
Low Oil Levels: Insufficient lubrication increases internal friction, rapidly raising the operating temperature.
Dirty Coolers/Radiators: Dust and debris on the cooling fins prevent effective heat dissipation. Regular cleaning is essential.
Poor Ventilation: If the compressor is in a cramped or poorly ventilated room, it will recirculate its own hot exhaust air.
High Ambient Temperature: Operating in environments exceeding 104°F (40°C) often triggers thermal shutdowns.
Faulty Thermal Valve: If the valve fails to open, oil is not directed through the cooler, causing the machine to overheat almost immediately. How to Reset the Alarm To clear a high-temperature fault on the
, follow these steps outlined in the ES3000 Instruction Book:
Identify the Alarm: Ensure the red LED is flashing, indicating a shutdown condition.
Wait to Cool: The temperature must drop below the set safety threshold (usually around 100°C/212°F) before the controller will accept a reset.
Press Reset: Press the Reset button (often marked with a '0' or circular arrow) to clear the error. When the ES3000 compressor controller detects a "hot"
Restart: Once the alarm clears, press the Start ("I") button to resume operation. Maintenance Checklist
