📖 Product Usage Instructions

The basic measurement chain can be understood as:

Vibration / Displacement Sensor → IOC4T → MPC4 → Signal Processing → Alarm / Protection Logic

The MPC4 receives dynamic signals from compatible machinery-monitoring sensors. It processes these signals using configurable filters and measurement functions, then compares the resulting values with programmed alarm thresholds.

For example, a proximity probe can be used to monitor shaft vibration or shaft position. The MPC4 processes the incoming signal and provides vibration or position information for continuous machinery monitoring.

The MPC4 also supports speed/phase reference inputs. This allows vibration measurements to be analyzed relative to rotational speed, which is particularly useful for rotating machinery diagnostics and order tracking.

📈 Signal Processing

The MPC4 supports several programmable processing functions.

🔹 Broad-Band Processing — High-pass, low-pass, and band-pass filters can be configured.

🔹 Narrow-Band Tracking — Used for tracking vibration components associated with rotating speed.

🔹 Amplitude Monitoring — Provides amplitude measurement for vibration-related signals.

🔹 Phase Monitoring — Speed/phase reference information can be used for phase-related analysis.

🔹 Alarm Processing — Alert and Danger thresholds can be programmed according to the monitored equipment.

The published specifications give an amplitude accuracy of approximately ±1% of full scale and linearity error below ±1% for the applicable measurement functions.

🚨 Alarm & Protection Functions

The MPC4 supports configurable protection thresholds.

🟢 OK — Measurement chain and monitored value are within the configured normal range.

🟡 Alert — Measurement has reached a configured warning threshold.

🔴 Danger — Measurement has reached the configured danger threshold.

Alarm delay, hysteresis, and latching can be configured according to the application.

These functions allow the VM600 system to provide early warning before a rotating machine reaches a more severe protection condition.
