Selection Guidelines
-
When to choose: Applications requiring combined measurement (bridge, pressure, pulse) and analog control in a single module.
-
Bridge Configuration: Configure excitation voltage per manufacturer specifications.
-
Pulse Configuration: Set scaling (pulses per revolution or per unit flow).
-
Control Configuration: Configure PID or feedforward control loops in Toolbox ST.
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.0 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.
-
Control Tuning: Perform PID tuning during commissioning—avoid overshoot and instability.
-
Calibration: Factory calibrated—verify against known references during commissioning.
-
LED Diagnostics: Green = normal; Amber = fault; Red = module fault.
-
Fault Log: Access 500-event log via Toolbox ST.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
ESD: Handle by edges with grounded wrist strap.
