6.2 Precautions

1. Installation Guidelines:
   • Mount GE IS200VTURH1B in a Mark VIe/Mark VI control rack with minimal vibration (远离 turbine-mounted equipment) to avoid measurement interference.
   • Use shielded twisted-pair wiring for sensor connections and ground the module per GE turbine control system guidelines to maximize noise immunity.
2. Configuration Notes:
   • Calibrate sensor inputs via ToolboxST software to match probe/accelerometer specifications (e.g., 3.33mV/mil for Bently Nevada proximity probes).
   • Set alarm/trip thresholds based on turbine manufacturer recommendations and API/ISO standards (e.g., 100 mils peak-to-peak for shaft vibration trips).
3. Troubleshooting:
   • For erratic vibration readings: Check sensor wiring integrity and verify module grounding—replace faulty proximity probes or accelerometers before recalibrating GE IS200VTURH1B.
   • For communication faults: Confirm Turbine Control Bus connections and check Modbus RTU settings (baud rate, parity) for remote monitoring.
4. Maintenance:
   • Recalibrate the module annually using a certified vibration calibrator to maintain measurement accuracy.
   • Inspect sensor connections quarterly for corrosion or damage, especially in harsh turbine room environments (high temperature/humidity).
