Selection Guidelines
-
When to choose:
-
Critical boiler and turbine protection requiring <3 ms response
-
Extreme environments (–30 to +75 °C, condensing, salt spray, chemical exposure)
-
Applications needing the highest accuracy and expanded diagnostics
-
Maximum reliability (nuclear, critical infrastructure)
-
-
When to choose “H2B” instead: For less extreme environments (0–60 °C, non-condensing) where silicone coating is not required.
-
Bridge Configuration: Configure excitation voltage per manufacturer specifications.
-
Protection Logic: Configure trip setpoints and 2-out-of-3 voting logic in Toolbox ST.
-
Coating Verification: Inspect under UV (365 nm)—silicone coating shows distinct fluorescence; verify edge encapsulation bead is continuous.
-
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 <3 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 1000-event log via Toolbox ST—review waveform 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; “H2BMD” backward-compatible with all BPPB sockets.
-
Firmware Updates: Ensure the GE IS210BPPBH2BMD is in “standby” mode during updates.
-
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.
