MACHINE CONDITION MONITORING Rotating machines are one of the key and most valuable components in a power system. Equipping rotating machines with systems for condition monitoring enables predictive maintenance and risk assessment. It ensures: Processing unit (real time processing, modular design, analog inputs/outputs, digital inputs/outputs, ICP, RTD, Pt100, thermocouple …) Higher machine availability Improved safety of service and no unplanned outages or dead times Longer service life Early fault detection Better resource management (time, human, capital) Process values – analog and digital...

1. MCM specification Architecture: • Data acquisition unit with the real time controller and local visualization Inputs: • Vibration inputs (IEPE) • Analog inputs (0-10 V / (0)4-20mA) • Speed sensor input(0-10 V) • Temprature inputs (RTD, Pt100) • Digital inputs • Additional inputs on request Digital/relay outputs: • Number of outputs: 2-8 • Continuous current: 6 A • Maximum switching power: 1500 VA • Maximum switching voltage: 250 VAC/DC • Maximum switching frequency: 0,1 Hz • Rated isolation voltage: 300 V overload (category III) by EN 50178 • Surge withstand: 4 kV (1,25/50 µs), by IEC 5017...

2. Software The processing units are connected through the standard communication protocols with server computer (central diagnostic computer). In addition to the measurement data display, the central diagnostic system enables through expert tools of the MCM system: analysis of the measured results, diagnostic monitoring, recording/storing measurement data and important events (e.g. alarms). MCM system enables local data visualization through operator touch panel. Local visualization enables insight into real-time data, alarms, trends and orbit plots. All screens can be modified according to...
