What to do if the Ingersoll-Rand Control Systems shows a low oil pressure trip?

C

If the Ingersoll-Rand Control Systems indicates a low oil pressure trip, it could be due to the oil pressure falling below the Oil Pressure Trip Value or an incorrect value read by the CMC. First, check the prelube pump and installation of a calibrated pressure sensor to verify the actual oil pressure. If the oil pressure is adequate, refer to the Pressure Monitoring System troubleshooting table, as the likely cause is a loose wire, terminal, or connector.
