Firmware Flash Compatibility and High-Speed Signal Execution
The terminal board processes physical feedback signals directly from LVDT and LVDR sensors to maintain closed-loop servo valve positioning. Firmware flash compatibility across the Mark VI rack architecture ensures seamless communication over the I/O backplane during real-time fuel and steam regulation tasks. Hardware logic circuits enforce strict signal isolation across both channels, suppressing electrical cross-talk while maintaining deterministic data transfer speeds to the primary controller.
Frequently Asked Questions
Q: How does the board handle signal routing in a Triple Modular Redundant (TMR) setup?
A: In TMR mode, the board splits feedback signals across three independent processor cards, enabling 2oo3 voting logic to maintain valve control without interruption even if one processor channel experiences a fault.
Q: What physical grounding procedures must technicians apply to LVDT feedback lines?
A: Ground all individual cable shields at the terminal block protective earth (PE) busbar using a single-point connection. Never ground shield wires at the field sensor junction box, as this creates ground loops that corrupt low-voltage AC position signals.
Q: Can maintenance staff swap terminal block connections while the board operates under live power?
A: Live hot-swapping of terminal wiring is prohibited due to the risk of arc generation and inductive kickback from active servo coil outputs. You must de-energize the servo drive loop and disable the associated valve hydraulic pressure prior to servicing field connections.
Field Installation Guidelines
Mount the board securely into the rack frame using the integral card guides to avoid mechanical deflection of the PCB traces. Ensure proper metallic contact between the board frame and cabinet PE ground before attaching terminal connectors. Route field cables carrying low-level LVDT excitation AC voltages in separate conduit tracks away from heavy three-phase AC power lines. Verify all terminal block screws are torqued according to cabinet assembly specs to prevent loose connections caused by turbine deck vibration.
