The returning RTD signal is processed using voltage-to-frequency converters, sample counters, and a VCO-type A\/D converter. Sampling rates are selectable: \u003cstrong\u003eNormal Mode\u003c\/strong\u003e at 4 samples per second, and \u003cstrong\u003eFast Mode\u003c\/strong\u003e at 25 samples per second. The digital signal processor also performs linearization for 15 selectable RTD types.\u003c\/p\u003e\u003ch3\u003eFault Detection\u003c\/h3\u003e\u003cp\u003eOut-of-range values trigger detection of RTD short circuits and open circuits. When an RTD exceeds hardware limits, the affected channel is removed from the scan while other channels continue operating normally. Repaired channels can be automatically restored after approximately 20 seconds, or manually restored.\u003c\/p\u003e\u003ch3\u003eTriple Modular Redundancy (TMR)\u003c\/h3\u003e\u003cp\u003eThe TRTDH1B configuration supports redundant RTD inputs in a Triple Modular Redundant (TMR) architecture. Inputs are distributed across three VRTD boards located in the R, S, and T racks. High-frequency grounding decoupling is provided on all RTD input signals. RTD multiplexing prevents loss of temperature data if a cable or VRTD board fails. RTDs are read simultaneously by the R, S, and T VRTD boards, with each board reading a different RTD pair to prevent simultaneous excitation, improving measurement accuracy.\u003c\/p\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eBefore installation, turn off power to the VME processor rack. Insert the board and press the top and bottom levers until the edge connectors are fully seated. Tighten the captive screws on the top and bottom of the front panel to secure the board.\u003c\/p\u003e\u003ch2\u003eDiagnostics \u0026amp; Configuration\u003c\/h2\u003e\u003ch3\u003eFront Panel LEDs\u003c\/h3\u003e\u003cp\u003eThree LEDs on the VRTD front panel indicate board status: \u003cstrong\u003eRUN\u003c\/strong\u003e (typically solid green), \u003cstrong\u003eFAIL\u003c\/strong\u003e (flashing green), and \u003cstrong\u003eDiagnostic LED\u003c\/strong\u003e (normally off; remains steady orange when a diagnostic alarm condition exists).\u003c\/p\u003e\u003ch3\u003eDiagnostic Functions\u003c\/h3\u003e\u003cp\u003eThe board performs hardware limit checking for each RTD type using predefined, non-configurable high and low thresholds near the operating range limits. When a hardware limit is exceeded, the input channel is no longer scanned, and a logic signal is generated instead. A composite diagnostic alarm (L3DIAG VRTD) is generated if any input reaches a hardware limit. Diagnostic information is available through the system toolbox. Individual diagnostic signals can be latched, and the RESET DIA signal can be used to clear latched diagnostics.\u003c\/p\u003e\u003ch3\u003eConfiguration Parameters\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Limits:\u003c\/strong\u003e Enable or disable system limit checking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto Reset:\u003c\/strong\u003e Enable or disable automatic restoration of RTD channels removed from scanning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroup A Rate:\u003c\/strong\u003e Sampling rate and system-frequency filtering for the first group of 8 inputs.
