Selection Guidelines
-
When to choose: Boiler and turbine protection applications requiring fast response, bridge sensors, pressure, and pulse inputs.
-
Bridge Configuration: Configure excitation voltage per manufacturer specifications.
-
Protection Logic: Configure trip setpoints and voting logic in Toolbox ST.
-
Pulse Configuration: Set scaling (pulses per revolution or per unit flow).
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.5 or higher.
Operational Precautions
-
Wiring: Follow GE wiring diagrams—correct polarity and shield grounding essential.
-
Bridge Excitation: Verify excitation voltage does not exceed sensor manufacturer specifications.
-
Protection Testing: Simulate over-pressure and over-speed conditions to verify <5 ms trip response.
-
Voting Logic Testing: Simulate single-channel failures to verify 2-out-of-3 logic.
-
Calibration: Factory calibrated—verify against known references during commissioning.
-
LED Diagnostics: Green = normal; Amber = alert; Red = trip/fault.
-
Fault Log: Access 750-event log via Toolbox ST—review waveform snapshots.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks—critical for protection availability.
-
Firmware Updates: Ensure the GE IS210BPPBH2B is in “standby” mode during updates.
-
ESD: Handle by edges with grounded wrist strap.
