Selection Guidelines
-
When to choose:
-
Critical vibration monitoring and active control requiring absolute reliability
-
Extreme environments (–40 to +85 °C, condensing, salt spray)
-
Maximum reliability (nuclear, critical infrastructure, military)
-
-
When to choose “H2AA” instead: For less extreme environments (–30 to +75 °C) where standard silicone coating suffices.
-
Vibration Input Configuration: Configure IEPE or proximity probes per channel.
-
Control Mode: Select active, shaping, adaptive, or modal control.
-
Coating Verification: Inspect under UV (365 nm)—thickest silicone shows distinct fluorescence; verify edge encapsulation bead is continuous.
-
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 1500-event log via Toolbox ST—review snapshots.
-
Coating Care: Use GE-approved silicone-safe cleaner; inspect annually under UV—rework voids with approved silicone coating per GE FSB-MKVIe-112.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks; “H2AM” backward-compatible with all UCVD sockets.
-
Firmware Updates: Ensure the GE IS215UCVDH2AM is in “standby” mode.
-
ESD: Handle by edges with grounded wrist strap—coating does not protect connectors.
-
Storage: Anti-static bag with desiccant at –40 to +85 °C; rotate every 3 years for coating inspection.
