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] When a compressor heats up it usually indicates there is too little lubricating oil within the system. Low pressure together with delayed airflow could signal internal damage within the system. A burning odor along with smoke indicates imminent danger therefore you should immediately stop the machine.
[pdf] 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.)
