Selection Guidelines & Recommendations
-
Channel Count: Up to 8 vibration channels per board.
-
Sensor Type: Configure per channel for accelerometer, velocity pickup, or proximity probe.
-
Vibration Scaling: Program scaling factors in GE ToolboxST for engineering units (mm/s, g, mils).
-
Sampling Rate: Configure sampling rate based on expected vibration frequencies.
-
Controller Firmware: Requires Mark VIe processor firmware v8.0 or later.
-
Wiring Guidelines: Use shielded twisted-pair cables for vibration sensors.
-
Spare Strategy: Keep one spare per turbine; lead times 6–10 weeks.
-
Retrofit: Direct replacement—regenerate configuration in GE ToolboxST.
Important Cautions
-
No Hot-Swap: De-energize rack before insertion/removal.
-
Sensor Polarity: Observe correct polarity for IEPE/ICP accelerometers and proximity probes.
-
Cable Length: For vibration sensors, use low-capacitance cables for long runs.
-
Grounding: Connect AGND to Mark VIe system ground at single star point.
-
Shield Termination: Ground sensor cable shields only at cabinet end.
-
ESD Handling: Use grounded wrist straps; field repair not possible.
-
Channel Mapping: With 8 channels, verify field wiring maps to correct ToolboxST channel numbers.
