Selection Guidelines
-
When to choose: Applications requiring higher channel density, faster sampling, and advanced control modes for vibration suppression.
-
Vibration Input Configuration: Configure IEPE or proximity probes per channel.
-
Control Mode: Select active vibration control, dynamic response shaping, adaptive filtering, or modal control.
-
Dynamic Analysis: Configure FFT, spectrum, order, transfer function, and cascade plots.
-
Modal Control: Configure for multi-mode vibration suppression.
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v7.5 or higher.
Operational Precautions
-
Wiring: Follow GE wiring diagrams—correct polarity for vibration sensors.
-
Vibration Sensor Verification: Verify sensor type and sensitivity during commissioning.
-
Control Tuning: Tune active control algorithms during commissioning.
-
Modal Control Tuning: Tune modal control parameters for multi-mode suppression.
-
Dynamic Analysis Baseline: Review baseline FFT, transfer functions, and cascade plots.
-
LED Diagnostics: Green = normal; Amber = fault; Red = module fault.
-
Fault Log: Access 1000-event log via Toolbox ST—review vibration/spectrum snapshots.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
Firmware Updates: Ensure the GE IS215UCVDH2A is in “standby” mode.
-
ESD: Handle by edges with grounded wrist strap.
