Selection Guidelines & Recommendations
-
Channel Configuration: Determine required mix of vibration and temperature channels.
-
Vibration Sensor Type: Configure per channel for accelerometer, velocity pickup, or proximity probe.
-
Temperature Sensor Type: Configure per channel for thermocouple type or RTD.
-
Controller Firmware: Requires Mark VIe processor firmware v7.5 or later.
-
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 vibration sensors and thermocouples.
-
CJC Protection: Do not apply conformal coating or tape over the terminal block area.
-
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: Verify field wiring maps to correct ToolboxST channel numbers.
