Core Functions

1. Multi‑sensor signal acquisition: Collects vibration, acceleration and shaft‑speed signals from field transducers for rotating‑machinery condition evaluation.
2. Condition‑monitoring calculation: Executes vibration‑analysis algorithms, computes bearing and gearbox health indices, compares measurements against configurable alarm thresholds.
3. Alarm & event capture: Generates level‑1 / level‑2 alarm outputs; captures fault timestamps and waveform snapshots for post‑failure root‑cause analysis.
4. Supervisory system interface: Modbus‑TCP uploads real‑time measurement values and alarm status to plant DCS / SCADA system.
5. Local discrete & analog outputs: Relay alarm contacts and analog output signals for local annunciator and auxiliary equipment.

Installation, Replacement & Critical Warnings

1. De‑energize 24 VDC auxiliary power before replacement. Unit is non‑hot‑swappable. Field transducer wiring should be isolated during terminal maintenance work.
2. After hardware replacement, download matching project configuration and firmware via dedicated 60M‑Series configuration software; factory default settings cannot be used for site operation.
3. Torque all screw‑terminal connections properly; loose terminals cause intermittent sensor signal dropout and false‑alarm triggers.
4. After power‑on, verify front‑panel LED status, check sensor signal quality, validate alarm thresholds and Modbus‑TCP data interaction with host system.

5. Common failure mode: Field‑wiring surge damage to sensor input circuits, Ethernet transceiver damage. Inspect transducer cabling when missing‑sensor or abnormal‑vibration alarms appear.
