The is a sophisticated electronic unit used in screw compressors (such as those from Chicago Pneumatic, Ceccato, and Alup) to monitor pressure, temperature, and service intervals. When your controller displays a "hot" or high-temperature alarm, it is often a safety shutdown to prevent internal damage. Understanding "Hot" High-Temperature Alarms
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
Much like a car thermostat, a faulty thermal valve may fail to direct oil through the cooler. How to Reset the Alarm es3000 compressor controller manual pdf hot
Ensure the cooling fan is rotating in the correct direction and moving air across the heat exchangers.
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. The is a sophisticated electronic unit used in
