III. Working Principle

The machinery protection unit composed of Vibro-meter 200-510-070-113, 200-510-111-034 and MPC4 acts as the signal processing core and fault protection hub of the VM600 system. Following the closed-loop workflow of Signal Collection → Signal Processing → Fault Judgment → Alarm Linkage, it connects sensors, IOC4T input/output cards, CPUM control modules and external protection devices to realize real-time monitoring, fault diagnosis and emergency protection of key rotating machinery. The detailed working process is as follows:

Signal Collection Phase: MPC4 cards collect original monitoring signals from accelerometers, velocity sensors, proximity probes, displacement sensors, speed sensors and other transducers via built-in interfaces or 200-510-111-034 shielded cables, and provide stable power supply for sensors. It supports synchronous acquisition of 4 dynamic signals and 2 speed signals. After internal noise filtering, purified original signals are sent to signal processing units. The 16-bit high resolution and high sampling rate ensure precise signal collection, and the built-in OK system monitors sensor operating status in real time to timely detect sensor faults and wire breakage.
Signal Processing Phase: MPC4 performs digital processing including filtering, integration, differentiation, rectification and order tracking on collected original signals to accurately extract key parameters such as vibration amplitude, phase, frequency and rotating speed, and analyze operating anomalies such as rotor unbalance, bearing wear and shaft misalignment. Processed parameters and analysis results are transmitted to CPUM modules via VME backplane bus for comprehensive analysis, and relevant signals are fed back to IOC4T cards to provide data basis for subsequent alarm and control actions.
Fault Judgment & Alarm Phase: MPC4 compares real-time monitored parameters with pre-configured Alert and Danger thresholds set by software. When values exceed alert thresholds, alert signals will be triggered and indicated by LED indicators, meanwhile alert information will be sent to CPUM and IOC4T cards. Once danger thresholds are exceeded or signal abnormalities are detected, emergency alarms will be activated immediately with preset alarm logics started. External audible & visual alarms will be driven through self-owned processing outputs or IOC4T cards to remind field staff of timely handling.
Protection Linkage & Status Feedback Phase: While triggering danger alarms, MPC4 interlocks external protection devices such as trip switches and emergency braking units through relay outputs of IOC4T cards to cut off power supply or stop equipment operation rapidly, so as to prevent fault escalation and avoid equipment damage and safety accidents. Meanwhile, MPC4 collects real-time operating data including signal processing status, alarm status and power status, as well as linkage feedback signals from sensors and external devices, and uploads all data to CPUM modules for remote status monitoring and quick troubleshooting. Automatic power-on self-check further enhances overall system reliability.

Relying on high-precision signal processing, flexible alarm configuration and superior reliability of MPC4 cards, the VM600 system realizes full-process monitoring and protection for key rotating machinery. Its complete filtering protection, diversified alarm logics, fast response speed and excellent module compatibility ensure accurate monitoring data, timely alarm response and reliable protection actions. Working with CPUM and IOC4T modules, it achieves full-process automatic management covering real-time monitoring, fault diagnosis, early warning and emergency interlock, effectively extending equipment service life, cutting maintenance costs and ensuring safe and stable industrial production. It should be noted that this series of MPC4 products are gradually phased out, so sufficient spare parts reserve shall be arranged in advance during application.
