Selection Guidelines
-
When to choose:
-
Critical protection requiring <2 ms response and highest accuracy
-
Extreme environments (–40 to +85 °C, condensing, salt spray)
-
Rate-of-change prediction for early trip detection
-
Maximum reliability (nuclear, critical infrastructure)
-
-
Bridge Configuration: Configure excitation voltage (0.25–10 V) per manufacturer specs.
-
Protection Logic: Configure trip setpoints and 2-out-of-3 voting in Toolbox ST.
-
Rate Prediction: Configure acceleration limits for predictive tripping.
-
Coating Verification: Inspect under UV (365 nm)—thickest silicone shows fluorescence; verify edge encapsulation.
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v7.0 or higher.
Operational Precautions
-
Wiring: Follow GE diagrams—correct polarity and shield grounding essential.
-
Bridge Excitation: Verify excitation voltage does not exceed sensor specifications.
-
Protection Testing: Simulate over-pressure/over-speed to verify <2 ms response.
-
Rate Prediction Testing: Simulate rapid acceleration to verify predictive trip logic.
-
Voting Logic Testing: Simulate single-channel failures to verify 2-out-of-3 logic.
-
LED Diagnostics: Green = normal; Amber = alert; Red = trip/fault.
-
Fault Log: Access 1500-event log via Toolbox ST—review waveform snapshots.
-
Coating Care: Use GE-approved silicone-safe cleaner; inspect annually under UV.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
Firmware Updates: Ensure the GE IS210BPPBH2CAA is in “standby” mode. Use ControlST v7.0 or higher.
-
ESD: Handle by edges with grounded wrist strap.
-
Storage: Anti-static bag with desiccant at –40 to +85 °C; rotate every 3 years.
