How to detect phase loss in screw air compressor

Checkout Current Transformers (CTs) and check resistance across each one while it is disconnected. All resistances should be within 10% of one another. Also do a diode test on the CT inputs on each compressor module. (The diode test is described in RTAA-SVB10B-EN.) [pdf]

How to check the oil of screw air compressor

Air compressor oil is standard or synthetic oil made specifically for air compressors. Unlike motor oil, air compressor oil does not contain detergent and typically has lower amounts of carbon, sulfur, an. [pdf]

How to check the fault light of screw air compressor

Check the pressure and temperature sensor and start button. If there is a disconnection or poor contact, it needs further inspection. Check the controller program. If it is a procedural error, you need to change the phase sequence of the power supply. Inspect the body.. Check the pressure and temperature sensor and start button. If there is a disconnection or poor contact, it needs further inspection. Check the controller program. If it is a procedural error, you need to change the phase sequence of the power supply. Inspect the body.. First, check that there isn't a very high air demand, or air leak somewhere. If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed). [pdf]
