Selection Guidelines
-
When to choose: Critical overspeed protection applications requiring redundant speed measurement with 2-out-of-3 voting per measurement point.
-
Redundancy Configuration: Use all 6 channels (3 pairs) with 2-out-of-3 voting per pair for maximum protection integrity.
-
Scaling Configuration: Enter correct pulses per revolution (gear teeth count) in Toolbox ST.
-
Trip Level Setting: Configure overspeed trip setpoint per turbine manufacturer specifications (typically 110–115% of rated speed).
-
Speed Mismatch Threshold: Default 2%—adjust based on sensor accuracy.
-
Coating Verification: Inspect under UV (365 nm) upon receipt.
-
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.
-
Sensor Gap Setting: For proximity probes, verify air gap and bias voltage are correct.
-
Speed Calibration: Verify speed reading against a known reference during commissioning.
-
Overspeed Testing: Perform simulated overspeed tests to verify <3 ms response and trip logic.
-
Voting Logic Verification: Simulate single-channel failures to verify 2-out-of-3 logic per pair.
-
Speed Mismatch Testing: Introduce a known offset on one channel to verify mismatch alarm generation.
-
Signal Quality Monitoring: Review amplitude trends in Toolbox ST—degrading amplitude indicates sensor/cable issues.
-
LED Diagnostics: Green = signal OK; Amber = marginal signal; Red = channel fault or overspeed condition.
-
Fault Log: Access 750-event log via Toolbox ST for post-event analysis.
-
Coating Care: Use GE-approved cleaner; inspect annually under UV.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks; “H1AA” backward-compatible with all DTUR/VTUR sockets.
-
Firmware Updates: Ensure the GE IS210DTURH1AA is in “standby” mode during updates.
-
ESD: Handle by edges with grounded wrist strap.
-
Storage: Anti-static bag with desiccant at –40 to +85 °C; rotate every 3 years.
